Abstract:
Les catalyseurs à base de zéolite ont été largement utilisés dans la conversion de la biomasse. Les rendements catalytiques des produits recherchés sont fortement limités en raison de la taille relativement petite des pores dans les zéolithes et la préparation du catalyseur par imprégnation conduit généralement à des nanoparticules métalliques relativement grosses et à un faible contact entre les sites métalliques et acides. Le but de ce travail est la conception de catalyseurs nanocomposites métal-zéolithe contenant des nanoparticules de ruthénium uniformément réparties dans les zéolithes hié

Abstract:
It is ideal to theoretically predict the activity of a catalyst. It has been recognized that not only the type of metal, but also its atomic size plays an important role in catalysis. In the past, atomic clusters have been created by sputtering from a sacrificial metal plate and then using a mass selector to choose cluster sizes from 1-233 atoms of gold. This approach has practical limitations. In this thesis, I describe a procedure by which atomic clusters of gold containing 1-8 atoms are deposited in polyaniline as an isolation matrix. My atomic deposition follows a cyclic pathway. Atom

Abstract:
This thesis investigates the nonlinear optical properties of ZnO and ZnO-Au composite nanostructures. For applications such as photodynamic therapy, it is desirable to use nanoparticles to generate localised UV emission while illuminating them with visible or infrared light. This is possible using nonlinear optical processes such as two photon absorption. Nonlinear optical processes however, are extremely weak, so this work investigates the potential of increasing the efficiency of two photon absorption in ZnO nanoparticles by coupling them to metal nanoparticles.

With all the improvements in cancer treatments, multidrug resistance is still the major challenge in treating cancer. Cells can develop multidrug resistance (MDR) during or after treatment, which will render the cancer cells resistant not only to the chemotherapy drug being used but also to many other structurally- and mechanically-different chemotherapeutics. In the first project, the main focus was on development of drug resistant cell lines by selection with taxol. Gene changes in the L1T2 cell line after treatment with Taxol was studied.

It is recently reported that, MOX can enter the human body through ingestion, inhalation, or by dermal penetration. Due to its high non-degradability, it can bind to the tissues of fruits and vegetables. When it is consumed, it can imposes sub-chronic and chronic diseases, by the inhibition of acetylcholinesterase in human metabolism. Therefore, for the first time, we reported a detection of non-enzymatic electrochemical sensor based on 3D porous phase graphene oxide sheets

Department of Ecology and Resource Management<br>PhDENV<br>Groundwater has traditionally been perceived to be low in chemical species toxicity and microbiologically 'pure'. However, depending on the geological chemistry, formations and anthropogenic activities creating the frequent occurrence of microbiological contamination and excess toxic chemical constituents, the high quality of groundwater as a drinking water source can easily be compromised rendering it unsafe, thus, leading to severe waterborne epidemics. The rapid increase in fluoride and microbial contamination of groundwater have be

The reduced graphene oxide (RGO) and a zinc oxide (ZnO) composite modified electrode has been used for the enzyme free detection of hydrogen peroxide (H2O2). Moreover, it also has been used as an immobilization matrix of glucose oxidase to construct the glucose biosensor. The model enzymes such as hemoglobin (HB) and GOx were immobilized at multiwa

In this study, we tried to improve the hydrogen storage properties of LiAlH4 by ball milling process. We introduced different carbon materials, metal/carbon composites, other catalysts. According to Temperature-Programmed Desorption (TPD)analysis, We found that by Supercritical carbon dioxide (scCO2)process synthesized Fe/Graphene composites obviously decreased the dehydrogenation temperature of LiAlH4. It’s catalytic effect better than VCl3, TiO2. By

By introducing KNO3 in the starting CNT pretreatment, the yield of GNRs can reach nearly 100%. In addition, it is possible to reduce 90% usage of the concentrated H2SO4. The experimental findings presented in this study show that engineering of the inter- and intratube intercalation of CNTs by suitable intercalation molecules is a key factor t

Therefore, it is suitable to develop as substituted materials of plastic. However, HPMC deforms easily when it bears the loading, causing real con-tact area and the adhesive force between HPMC and counter(AISI52100) increase, so that the HPMC film is easily damaged due to adhesive wear, and leading to lose efficacy on wear resistance.
