Abstract:

The present developmental trend is towards the new types of devices with compact size, which led to the miniaturization, better performance, reliability coupled with low cost production, low pack weight where the thin film devices and components are preferred than bulk counterparts. Nowadays the research has been raised in thin film technology due to its extensive applications in the diverse fields such as optics (anti reflection coatings, solar cells), mechanics (adhesion providers, hard layers), magnetic (Squids, video tapes), space science, semiconductor technology (resistors, capacitors), chemistry (protection against corrosion, sensors), aircrafts, defense (coatings on components) and other industries. Out of these, chromogenic devices based on electro-chromism highly attract researchers where the optical modulation (transmittance, reflectance) takes place in a reversible manner with the application of a low voltage. The schematic representation of electro-chromic window consists of seven layers. The thin films of the suitable electro-chromic layer (tungsten trioxide) and the stock layer (vanadium pentoxide) are coated with either physical or chemical vapor deposition technique at desired parameters. The liquid or solid can be used as electrolytes. In this connection our investigations are towards to improve the efficiency, response time and stability of electro-chromic layer of tungsten trioxide

Abstract:

Biosensors have witnessed an everlasting interest because of their wide applications in different areas including medicine, biomedical, environment and food industries. Biosensors are one type of small devices for detecting target analyte that are usually bio-molecules such as antigen, antibody, protein, peptide, enzyme, DNA and RNA. A biosensor can be defined as a compact analytical device or unit incorporating a biological or biologically derived sensitive recognition element or bio-receptor integrated or associated with a physiochemical transducer. The bio-receptor recognizes the target analyte, while the transducer converts the recognition event into a measurable signal which can be weighted and measured electrically, optically, electrochemically or mass-sensitive. The uniqueness of a biosensor is that the two components; bio-receptor and transducer are integrated into one single sensor. Many different fabrication techniques for different types of biosensors have been examined in this presentation. The utilization of new coming Nano-Materials (NMs) has promoted the development of DNA biosensors towards the goal of smart, simple and inexpensive detection for targets analyses. Ideal NMs must comprise a range of fundamental properties like the ease in preparation, availability and an abundance of functional groups, large surface/volume ratio and chemical stability for the use as a suitable matrix in biosensor fabrication. Crucial parameters such as sensitivity, specificity and selectivity are discussed in this presentation.

Abstract:

A triphenylamine hyper-branched Schiff base was prepared in a good yield and molecular weight using Schiff reaction between mono- and tri-formyl derivatives of Triphenylamine (TPA) and selected aromatic and aliphatic diamine compounds to give amine-imine multi-anchored product. Triphenylamine as electron donor and hole transport group was devised and synthesized and complexation of the multifunctional products isolated with metals such as Cu2+, Ni2+, Pt2+, Ni2+ was carried out. The structural properties of the isolated products can be verified by Fourier Transform IR (FT-IR) spectroscopy and other techniques. Chemical oxidation of the product of the condensation reactions gives a stable cation radical which can be used in polymerization of epoxide and vinyl monomers and as a powerful one electron oxidizing reagent in organic reactions, at room temperature

Abstract:

Pure vanadium pentoxide thin films were prepared by electron beam evaporation technique onto well cleaned corning 7059 glass substrates. The films were prepared at an oxygen partial pressure of 2´10-4 mbar and at substrate temperatures ranging from RT to 450 oC. The deposited films were characterized to study the effect of substrate temperature on the structural and optical properties. As the films deposited at room temperature are amorphous in nature which was observed from XRD and Raman studies and confirmed by the AFM image, the studies are aimed at physical properties of the films deposited at substrate temperatures 250 oC, 350 oC and 450 oC. The XRD data revealed the orthorhombic structure of the films with well-defined peaks and the crystallite sizes were calculated by Debye-Scherrer formula. The variation in crystallite size with respect to substrate temperature and the average grain size from AFM studies were also discussed. The Raman spectra of the films deposited at Ts from 250 oC to 450 oC are well resolved and exhibiting the polycrystalline nature of the films. The optical band gap values are calculated from the optical transmittance spectra

Abstract:

A simple and rapid method has been developed for solvent extraction and separation of tin (II) using O-Methylphenyl Thiourea (OMPT) as a sensitive reagent. The basis of the proposed method is tin(II)-OMPT complex formation in aqueous potassium iodate media (0.1 mol L-1) and it is extracted into chloroform. The absorbance of complex was measured at 504 nm. Beer’s law was obeyed up to 9 µg mL-1 of tin(II). The molar absorptivity and Sandell’s sensitivity of the complex were 1.2457×104 L mol-1 cm-1 and 0.0955 µg cm2 respectively. The stoichiometry of tin(II)-OMPT complex was 1:2 established from slope ratio method, mole ratio method and job’s continuous variation method. The stability of tin(II)-OMPT complex was >12 hours. The proposed method is free from interferences from large number of foreign ions. The proposed method was successfully applied for separation and determination of tin(II) from real samples (environmental and food), binary and ternary synthetic mixtures. Precision of method was checked by finding relative standard deviation for 10 determinations was 0.23%. Sequential separation method has been developed for separation of antimony(III), lead(II) and tin(II).

Title: Electronic structure and formation energy of TiCxH2-xalloys: DFT study

Time : 13:50-14:10

Speaker
Biography:

Dr Said have a Ph.D. in Physics from the University of Jordan (August 2011). After I got my Ph.D. degree, He have worked as an assistant professor of physics since in two private universities in Riyadh. My dissertation is to investigate theoretically by using and employing the computational methods and technologies, of the Half-metallic properties and spin polarization of Heusler alloys which used in spintronics technologies. Through working as an assistant professor of physics, in addition to physics courses I taught both mathematics and statistical courses. Also, I contributed to many committees such as quality assurance committee. These experiences make me more dynamic and confidence to teach any courses in physics and mathematics. My research focuses on subjects central to study and investigate computationally, from an ab initio standpoint, the electronic and magnetic properties of new functional nanomaterials such as catalyst, topological insulators, Half-metallic etc. One of the most important interests for me is to construct and modeling calculations by the clustering solution. If there are a clustering solution and HPC technology in your department, I can use these facilities and pursue my research projects. Furthermore, I was attended many workshops and tutorials in High-Performance Computing (HPC) and computational physics, which was very interesting and useful for me. My experience and knowledge in ab initio packages such as Wien2k and abinit, OS operating systems and C/C++ and FORTRAN programming qualified me to be a computational physics researcher.

Abstract:

In this work, the electronic structure and formation energy of TiCxH2-alloys (x=0, 0.25, 0.5, 0.75, 1) are investigated by performing density functional theory calculations. The total energy calculations showed that hexagonal close-packed (h.c.p) structure is more preferable and stable than cubic (f.c.c) one for x  1/2. The results showed that for the cubic (f.c.c)structure, Hydrogen atoms are occupied partially both octahedral and tetrahedral interstices while carbon atoms occupied only the octahedral interstices. In the other hand, the hexagonal close-packed (h.c.p) structures showed that the octahedral interstices are fully occupied by carbon and the tetrahedral interstices are partially occupied by hydrogen.

Helanka J Perera has completed her PhD from Oklahoma State University, USA and is currently an Chemistry Assistant Professor in Maths and Natural Science Department at Abu Dhabi Women’s College, UAE. Her research interests are in material science, surface modification on micro and nanomaterials, superhydrophobicity, hydrophobicity, polymer and surface characterization.

Abstract:

Superhydrophobic/hydrophobic coatings were made using Fluorinated (FS) and Non-Fluorinated (NFS) Silane treated Diatomaceous Earth (DE) with different polymeric resins/binders. These coatings have been characterized with contact angle measurements, scanning electron microscopy and thermogravimetric analysis. Contact angles greater than 150° were attainable if the particles were sufficiently coated with fluorinated and non-fluorinated coupling agents and also if there were enough particles in the coatings. The critical particle loadings depended on the resin/binder system used. The behavior of these surfaces mimics that from, for example, the lotus leaf as they had low surface energies and also appropriate nano-micro structures.

Abstract:

Nanoscience and nanotechnology have been an interesting field of research and gained much importance from last two decades. Nanotechnology is fundamentally changing the way in which materials are synthesized and devices are fabricated. Incorporation of nanoscale building blocks into functional assemblies and further into multifunctional devices can be achieved
through a “bottom-up approach”. Research on the synthesis of nanosized material is of great interest because of their unique properties like optoelectronic, magnetic, and mechanical, which differs from bulk. Nanostructured materials are being viewed as the future material and for
various diverse applications in areas such as biomedical science, optics, mechanics, magneticscatalysts, biosensors and energy science.
Biological methods can be used to synthesize silver nanoparticles without the use of any harsh, toxic and expensive chemical substances. Green synthesis approaches of producing NPs are an alternative source of conventional method and possess excellent antimicrobial activity.Nonalcoholic fatty liver disease is a common clinic pathological condition characterized by significant lipid deposition in the hepatocytes of the liver parenchyma. The pathological picture
bears a striking resemblance to that of alcohol-induced liver injury, but it occurs in individuals who deny a significant history of alcohol ingestion. The effect of complex mixtures on several cellular responses, in an invitro liver model using human hepato carcinoma (HepG2) cells, was studied.
The synthesis nanoparticles were characterized by Uv-Visisble sepectroscopy, FTIR, SEM and EDX, TEM,XRD. AgNps of A.malabarica on HepG2 cell line showed dose dependent activity performed by laura talarico, 2004 method. The AgNP’s exhibited good cytotoxic effect . Activation of the caspase-3 pathway is a hallmark of apoptosis and can be used in cellular assays to quantifyactivators and inhibitors of the “death cascade.” The nano based phyto medicine will certainly provide and serve the line of safety and also willbe used as eco- friendly than allopathicchemically synthesized drugs in future.

Abstract:

Supported TiO2 nanoparticles were synthesized by sol-gel method using blue-green phosphor and characterized using X-ray diffraction (XRD), diffused reflectance UV-Visible spectroscopy, fourier-transform infrared, and electron microscopy techniques. The XRD study reveals that the TiO2 crystal structure does not transform from anatase to rutile phase till 600 ºC. Covalent interaction between the phosphor and TiO2 is evident from the diffuse reflectance spectra showing red shift in wavelength. The band-gap has been tuned to absorb light in the visible range. TEM micrographs of the as-prepared materials revealed presence of well dispersed polycrystalline TiO2 nanoparticles on the surface of the phosphor substrate. The difference in size of TiO2 particles that are bonded to the phosphor is attributed to the magnitude of Lewis acid-base interactions between TiO2 and phosphor support. Photocatalytic activity of as prepared nanocomposite was investigated by photodegradation of model organic pollutant methylene blue under UV and visible light. The nanocomposite catalyst showed highest photocatalytic activity

Speaker
Biography:

Dr Ahmed presently working as a Researcher at Petroleum Institute Research Center of Khalifa University of Science and Technology, Abu Dhabi, UAE in the field of corrosion coatings based on polymers for oil/gas industry. Ahmad Tabish, a graduate in Chemical Engineering from Aligarh Muslim University, India; batch 2014. He have a good International and National exposure in working in Research projects. Presently, I am a Researcher at Petroleum Institute of Khalifa University of Science and Technology, Abu Dhabi National Oil Company (ADNOC) at Abu Dhabi, UAE. My Research work includes synthesis of self-healing anti corrosion coatings based on nano-materials.

Abstract:

The issue of corrosion is a well-known problem and it causes the weakening of metal and its properties and makes it unfit for use. Corrosion causes enormous economic losses consistently over years in equipment maintenance, repair, and its substitution. In Gulf Cooperation Council (G.C.C) countries, money spent into corrosion control and repair are extremely dependent on production of oil, refining and petrochemicals sector shall be noteworthy as it comprises more than 33% of gross domestic products. Until now, various coatings have been developed to tackle this problem like sacrificial coatings, barrier coatings, noble metal coatings and electrically resistive coatings. In this study, self-healing smart anti-corrosion coatings were synthesized as it is a much lesser investigated area of research. Functionalized particles from mesoporous carbon along with mesoporous silica etc. were used as Nano containers for encapsulation of corrosion inhibitor for self-healing purpose using layer-by layer (lbl) self-assembly method and their effect on performance of coatings were studied after adding in commercially available polymer matrix against the corrosion of mild carbon steel in seawater. A series of tests were conducted on the resultant coatings to investigate their corrosion resistance, self-healing performance etc.This study will evaluate the protection offered by coatings of commercially available porous materials against the corrosion of mild steel in seawater, along with addition of different encapsulated nano containers in the polymer matrix. Benzotriazole (BTA) was used as a corrosion inhibitor in this study for synthesizing Nano containers. Self-healing smart anti-corrosion coatings, is a much lesser explored area of research with the major challenge of low adhesion properties and release of Nano containers to heal the corroded metal substrate. This calls for preparation of substrate surface and treatment of coatings to establish good interfacial interaction of the nano containers with the porous material and their successful release in the medium upon a pH change to avoid delamination/corrosion of coatings in water.The potential of the functionalized carbon materials to further enhance anticorrosion performance of the self-healing coatings was also evaluated. The coatings were prepared by brush coatings as well as dip-coating methods in determined optimal conditions on clean polished mild carbon steel coupons. The coating degradation behavior and corrosion resistance was investigated by the immersion tests (performed in 3.5 wt. % sodium chloride solution) and Potentiostatic Electrochemical Impedance Spectroscopy (PEIS). Brunauer–EmmettTeller (BET) testing was done only initially in order to determine the degree of impregnation in the pores of the carbon and silica materials. Corrosion monitoring was performed using Linear Polarization (LP) technique. Other nanocapsules characteristics were studied using techniques such as Fourier Transform Infrared Spectroscopy (FTIR), X Ray Diffraction (XRD) was used to characterize the composition of the multilayers of the Nano capsules, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were used to analyze the surface morphology of coatings as well as nanocapsules. The visual appearance of coating and corrosion products was studied using Optical Microscopy (OM). Coating thickness measurements were done using a standard PosiTector gauge. Zeta Potential was also analyzed continuously during the synthesis of nanocapsules in order to optimize the layer-by-layer assembly of a self-healing coating. Ultraviolet–visible spectroscopy (UV-Vis) was also studied to analyze the release behavior of the synthesized Corrosion Inhibitor encapsulated Nano containers in different pH of water. Self-healing testing of the synthesized coatings based on ASTM D7027-13 standards was also carried out to analyze the coating performance when exposed to corroding conditions.The electrochemical impedance spectroscopy (EIS) results illustrated the improved corrosion resistance of the coating based on carbon materials. The proposed coating also had a rapid self-healing ability in the presence of water. The mesoporouscarbon based coatings produced, were highly stable and protective in nature. The self-healing coatings possessed high impedance good barrier characteristics. The mesoporous carbon and functionalized mesoporous carbon coatings were compared with coatings of mesoporous silica and commercially available vinyl acrylate. The SEM analysis also revealed successful release of BTA onto the corroded surface thus verifying the self-healing effect. UV-Vis predicted that the carbon based capsules had more impregnation of the corrosion inhibitor than the silica based nanocontainers. It was observed that carbon based coatings and its 5 wt. % composition in the polymer matrix had better anticorrosive performance and adhesion than the silica coatings and provided much greater substrate protection as explained in the work in detail.

Abstract:

In this paper, Novel Magnetically Chitosan@N-Heterocyclic Carbene-Palladium (NHC-Pd) Coated Multi-Walled Carbon Nanotube (MWCNTs) was synthesized in three steps:

1) the reaction of Chitosan, glyoxal  and formaldehyde for synthesis of Chitosan@imidazol,

 2) Synthesis of magnetic functionalized-MWCNTs and 3) the esterification reaction via the reaction of hydroxyl and carboxylic acid groups of Chitosan@imidazol and magnetic functionalized-MWCNTs respectively, and followed with the attachment of palladium chloride to compose of novel NHC ligand for the first time. Catalytic studies of Magnetic Chitosan@ NHC-Pd Coated MWCNTs for the Suzuki cross-coupling reaction of various aryl halides with aryl boronic acids have been evaluated in the ethanol–water solution. In general, our new catalyst showed superior reactivity for this model reaction. Moreover, the heterogeneous catalyst can be easily recovered by external magnet field and reused for subsequent use without any significant loss in catalytic activity.The Suzuki–Miyaura cross-coupling reaction is important synthetic transformations that is widely employed for the preparation of biaryl compounds in a great variety of industrial applications including the production of natural products, agrochemicals and pharmaceuticals. Challenges facing this reaction are the employ of catalysts that are efficient with higher turnover frequencies (TOF) and turnover numbers (TON), easily recoverable and can operate in environmentally benign solvents.  Therefore, much recent effort has been Search and made approaches to develop efficiently heterogeneous Pd-catalyst systems

Title: Advanced epoxy resins for making structural composites

Time : 11:50-12:10

Speaker
Biography:

Mohammad Hosain Beheshty has received his PhD from Bath University, UK. He is the Head of Composite Department of Iran Polymer and Petrochemical Institute and Chairman of Iran Composite Scientific Association. He has published more than 85 papers in reputed journals and has been serving as an Editorial Board of Iran Polymer Journal and Iranian Journal of Polymer Science and Technology.

Abstract:

Epoxy resins are widely used in different industries as adhesives, surface coatings and matrix of composites. This is due to their unique properties including excellent mechanical and electrical properties, thermal and chemical stability. The pure or virgin epoxy resins have high viscosity and the inherent toughness of polymer network is low. Some additives like diluents, fillers (micro or nano) extenders, adhesion promoters and toughening agents usually are being used in epoxy formulations in order to make a suitable or advanced epoxy matrix. Much research has been carried out to enhance the toughness of the cured epoxy resins. The general strategies used are introduction of flexible chain into the network structure (e.g. ether linkage), compatible blending with flexible or ductile polymer, reduction in crosslink density of network and introduction of a suitable matter like rubber, thermoplastic or rigid particles as a second phase. For a decade we have done a comprehensive work in the area of modifications of epoxy resins in order to develop an advanced epoxy matrix system suitable for making glass or carbon/epoxy prepregs. These includes selection of suitable epoxy resins, curing systems, modification of an epoxy system by using reactive diluents, toughening of a system by using carboxyl-terminated Copolymer of Butadiene and Acrylonitrile (CTBN), poly (propylene oxide) based amine (Jeffamine D-400) or long-chain hardener and Hydroxyl Terminated Poly butadiene (HTPB), micro capsulation of curing agent and developing new latent accelerator

Abstract:

Irradiation of poly (4-ethoxystyrene) in solid films and at 265 nm at room temperature showed a gradual photo-degradation of polymeric chains. Degradation was accelerated by the presence of air and rise in temperature. The degradation process was followed by UV-VIS, fluorescence and FT-IR Spectroscopic techniques. The intensity of absorption spectra was increased by the increase in irradiation time in both solid films and in solution; on the other hand the intensity of fluorescence was decrease upon the increase in irradiation time and increase in the amount of blended phthalate and terephthalate plasticizers. Some kinetics work was applied to the results on fluorescence intensity of the excimeric emission to evaluate the quenching efficiencies and photo quenching rate constant by applying Al Ani Hawi equation. The analysis of the FT-IR spectra of the irradiated and non-irradiated samples, showed a noticeable formation of new bands and their intensity was found to increase with the increase in irradiation time and also with the increase in the amount of added plasticizer. In addition, the observed increase in the intensities of the carbonyl and hydroxyl absorption regions of the FT-IR spectra, providing evidence for the photo-degradation as well as photo-oxidation of polymeric chains

The analysis of the FT-IR spectra of the irradiated and non-irradiated samples, showed a noticeable formation of new bands and their intensity was found to increase with the increase in irradiation time and also with the increase in the amount of added plasticizer. In addition, the observed increase in the intensities of the carbonyl and hydroxyl absorption regions of the FT-IR spectra, providing evidence for the photo-degradation as well as photo-oxidation of polymeric chains

Abstract:

In modern years there has been an enormous interest in electrochromic technology, which triggered the designing and fabrication of efficient electrochromic devices (ECD) which work on the phenomena of electrochromism, in which a reversible optical modulation in the materials can be achieved by intercalation/deintercalation of small cations and electrons by the application small electric field. Tungsten trioxide (WO3) is one among the various EC transition metal oxides recognized as best EC material in thin film form. It exhibits large optical modulation, good durability, stability, low power consumption for the prepared ECDs.

                                 WO3(Transparent) + xH+ + xe-  ↔ HxWO3(Blue)

        In the present work, WO3 thin films were prepared by electron beam evaporation technique at various oxygen partial pressures (PO2) ranging from 2x10-3 to 2x10-5 mbar and at the substrate temperature of 250 oC. The films were deposited onto well cleaned glass, ITO coated glass and silicon substrates. The influence of oxygen partial pressure on the growth, morphology, optical and electrochromic properties have been investigated. The XRD studies revealed that the phase transformation taken place from orthorhombic to monoclinic with respect to PO2 from 2x10-3 to 2x10-5 mbar. The maximum optical bandgap of   3.28 eV was obtained for the films deposited at 2x10-5 mbar and decreased to 2.66 eV for the films deposited at 2x10-3 mbar. The coloration efficiency of WO3 films at the wavelength of 550 nm were found to be 50.84, 29.56 and 24.95 cm2/C for the films deposited in the PO2 of 2x10-3, 2x10-4 and 2x10-5 mbar respectively.

Abstract:

Graphene is an atom-thick material that shows distinct electrical and mechanical properties, thanks to its hexagonal-lattice of carbon atoms. For instance, graphene-based-platforms offer a basis for compact and tunable photonic devices. This is because graphene waveguides offer nanoscale optical confinement, tunable graphene conductivity in the optical range, desirable properties of being able to stand alone, and good compatibility with a wide diversity of optical and electronic materials. In this presentation, we present our recent work on exploiting graphene layers to achieve frequency switching, and giant amplification, of photonic signals in the terahertz frequency range, owing to the distinct graphene
properties.

Biography:

Muteeb Siddiqui has completed his Engineering at the age of 21 years from Hamdard engineering University and. He is the Process Engineer of Octal, world largest PET manufacturer clear regin packing facility in Oman. He has vaste experience of working in different polymer plant of resin and downstream products. 

Abstract:

Future plan to make PET Heavy metal free for human friendly packaging material, toxic heavy metal has to be replaced with light metal catalyst is the ultimate objective. Adverse effects of heavy metals including, life threatening diseases by damaging of brain, kidney, lungs in fact damage to all major organs. At present heavy metal migration limits are 40 ppb. For one of its kind project, series of trial were designed, out of which first two light metal catalyst trials on one of the world largest PET production lines did not results in the desired heavy metal free process with high process stability and high production quality as demonstrated on pilot lines. Therefore, a second pilot plant trial was executed to define root causes. In the latest pilot plant trial results from previous pilot plant trials could be repeated and exceeded by switching the new catalyst injection point from post-ester (second chamber of reactor) into esterification (first chamber of reactor), respective in the paste tank (giving it better mixing and more residence time). It has to be mentioned that in early commercial line trials it was thought that the new catalyst (light metal) could be partly deactivated in the easterification reactor due to too high end groups (COOH) and water content and that it would be most safe to feed the catalyst into the post ester reactor. Furthermore the esterfication reaction is auto-catalyzed by H+ from the COOH and can run without any catalyst. After the commercial trials, the suspicion arose that the catalyst suffers a poor mixing when fed in the post-ester and that it should be tested to feed the catalyst into the paste or esterification chamber to ensure complete mixing. During pilot plant trial, it was a great surprise when feeding the new catalyst (light metal) in the esterification reactor that even with only 7.5 ppm it was possible to reach a stable viscosity after the melt phase polymerization of 0.80 dl/g at 100% name plate capacity. The slight deterioration in optical quality was later easy to adjust to standard color with addition of a small amount of toner. Another finding in that trial was that the esterfication conversion should be above 90% otherwise a loss of viscosity after melt phase polymerization is possible. Along with minimizing human health concerns, stable process, energy efficient and better optical quality in PET are of prime interest in the establishment of light metal catalyst.

She has published two research papers to her credit

Abstract:

Nanotechnology can be defined as research for the designing synthesis and manipulation of the structure of particles with dimension smaller than 100 nm. Metal nanoparticles have been studied extensively because of their unique physicochemical properties. Biological methods of nanoparticle synthesis using microorganisms, enzymes/proteins and plants extracts has been suggested as possible eco-friendly methods of synthesis alternatives to physical and chemical methods. Recently, nanomedicine has become a leading research field. Scientists are involved in developing safe, effective, cheaper and less toxic drugs or carriers to combat diseases like cancer, epilepsy, etc. Use of plant for synthesis of nanoparticles could be advantageous over other environmentally benign biological process as this eliminates the elaborate process of maintaining cell cultures. Plant use can also be suitable scaled up for large scale synthesis of nanoparticles. In the plant mediated green chemistry approach, the reduction are of metals salts is very fast and the procedure itself requires no specific conditions unlike the physical and chemical. Therefore medicinal plants of well established therapeutic importance are being widely used for the Green synthesis. Medicinal plants are used by 80% of the world population for their basic health needs. India is the birth place of renewed system of indigenous medicines such as Siddha, Ayurveda and Unani.

Biography:

Ebtesam Mohammed Al-Shanqiti has completed her doctorate in King Abdulaziz University, Saudi Arabia

Abstract:

In the current work, Chitosan (CS) underwent modification with Alginic acid (AG), Hydroxyapatite (HA), multi-walled Carbon Nanotubes (CNT) and cross-linked with Glutaraldehyde (GA). All products were characterized and compared with blank CS. All materials showed the characteristic bands of FT-IR spectroscopy. Thermal degradation of modified CS was also investigated by thermal analysis. There was a slight weight loss % up to 240 °C followed by Extensive Weight Loss (EWL) % up to 420 °C. After that, there was a slight weight loss until the end of measurement at 700 °C. EWL % depends on the modifier content. Generally, modified CS is more thermally stable than the unmodified ones. For CS/AG blends, thermal stability was higher for 10% AG content than others for both cross-linked and uncross-linked samples. In case of CS/HA composites, 20% HA modified CS showed higher thermal stability than others with no significant difference among them but significant if compared with the unmodified CS. For CS/HA/CNT composites, CNT helps samples to be thermally more stable than CS/HA composites. It would be more beneficial to use CNT only in the composite formation but the functions supplied to the composite by HA are sometimes crucial where the chemical structure and features of HA are required to be involved in the composite characteristics. Ability of matrices to uptake metal ions was determined by using Cu (NO3) and it could be arranged as CS/AG/GA>CS/GA>CS/HA/CNT/GA>CS/HA/GA. Modified CS was used for drug delivery by using 5-Fluorouracil (FU) as antitumor model drug. Most of FU was released within 24 hours while maximum release was after 48 hours. It could be concluded that the ease of release of FU from the investigated matrices could be arranged from the fastest to the slowest matrix in the order of P111F>P121F>P311F>P411F>P321F>P421F

Helanka J Perera has completed her PhD from Oklahoma State University, USA and is currently an Chemistry Assistant Professor in Maths and Natural Science Department at Abu Dhabi Women’s College, UAE. Her research interests are in material science, surface modification on micro and nanomaterials, superhydrophobicity, hydrophobicity, polymer and surface characterization.

 

Abstract:

Superhydrophobic/hydrophobic coatings were made using Fluorinated (FS) and Non-Fluorinated (NFS) Silane treated Diatomaceous Earth (DE) with different polymeric resins/binders. These coatings have been characterized with contact angle measurements, scanning electron microscopy and thermogravimetric analysis. Contact angles greater than 150° were attainable if the particles were sufficiently coated with fluorinated and non-fluorinated coupling agents and also if there were enough particles in the coatings. The critical particle loadings depended on the resin/binder system used. The behavior of these surfaces mimics that from, for example, the lotus leaf as they had low surface energies and also appropriate nano-micro structures.
