The Raman vibrational spectra of water inside mesoporous silicate are measured in a temperature range of 100 T 303 K. It is found that the Raman spectrum of confined water becomes more different from that of bulk water with the decrease of water content in pores. For samples with high water content in pore, the main p…
12- or 18 wt.% cobalt and 0.5 wt.% rhenium was impregnated on nickel-aluminate spinel support supplied by Statoil R&D. The catalysts were dried in an autoclave continuous stirred tank reactor with different reactor parameters. Reactor parameters, such as duration, temperature and stirring rate were adjusted in each ex…
Four types of nonwoven materials produced by Struto technology have been investigated. These materials have different composition and surface mass. The air permeability, behavior under loading and after relaxation, capillary action and thermal conductivity have been determined. The results obtained make it possible to…
Dans cette thèse sur la conception et la réalisation d'une structure pixellisée transparente pour laquelle la diffraction et la diffusion doivent être imperceptibles, la structure à double damier empilé a été la mieux adaptée. Une étude des techniques de lithographie pour les grandes surfaces est proposée. L'objet est…
We studied the effects on structural and magnetic phase transitions and the emergence of superconductivity in transition metal substituted BaFe2As2. We grew four series of Ba(Fe1-xTM2)2As2 (TM=Ru, Mn, Co+Cr and Co+Mn) and characterized them by crystallographic, magnetic and transport measurements. We also subjected Ba…
The purpose of this dissertation was to synthesize and evaluate porous poly(2- hydroxyethyl methacrylate) (PHEMA) and PHEMA composite hydrogels containing various concentrations of titanium dioxide (TiO2) nanoparticles, silicon dioxide (SiO2) nanoparticles, and multi-walled carbon nanotubes (CNTs) for tissue engineeri…

A heat stable complex polysaccharide (molecular weight of 4300 Da) purified from the cell wall of the fungus Mucor rouxii (CPM) and a cationic polysaccharide from crab chitin (CPP) are potent antifungal agents both in vitro and in vivo . These compounds possess several highly desirable characteristics for the next gen…
The objective of the present study is to develop a novel microactuator by using a liquid crystal.As a fundamental experiment,we tried to move a liquid crystal droplet(4-cyano-4'n-pentylbiphenyl) put on a flat glass plate.A transparent electrode layer(ITO layer) was formed on the glass plate The ITO layer was divided i…
The occurrence of columnal euhedral „biotite“ crystals with focus on their crystallochemical properties, mineral inclusions and alteration products from granodioritic rocks of the „Kralovo Pole“ unit, Brno Massif, have been studied. Micromorphological descriptions, microprobe analysis and X-ray powder diffraction were…
Studies of magnetism at reduced scales have revealed new phenomena that are distinctly different from their bulk counterparts providing insight to the fundamental mechanisms that govern magnetism and other correlated properties. To this end, the use of heteroepitaxy and heterostructures is invaluable for investigating…
Glia are well known for providing essential physical and metabolic support to neurons, as well as regulating neuronal development. Glial development is also modulated by external signals from other cells and the extracellular matrix (ECM). Many signals are transduced into glia by specific receptors, such as integrins…
Molecular sensors based on surface-enhanced Raman scattering (SERS) and optical fibers have been widely used in chemical and biological detections due to their unique advantages: molecular specificity, high sensitivity, flexibility, and in-situ remote sensing capability. In this chapter, we review the development of f…
Abstract The topic of this update is synthesis of silenes, compounds with Si=C bonds, which are generally highly reactive and sensitive to the ambient atmosphere. Synthetic routes published since 2001 yielding either persistent silenes or transient silenes that can be trapped by suitable reagents are discussed. Both n…
IN PREPARATION OF THIS CHAPTER, THE CONTENTS of the 14th edition of this manual were drawn upon. The author acknowledges the author of the chapter in the 14th edition, Richard J. Burns. The current edition will review, alter, and update the topics as addressed by the previous author and ensure that any ASTM documents…
Mechanism for obtaining urea-formaldehyde resins is very complex and process of formation of resinous substances in the condensation of urea with formaldehyde has not been sufficiently studied. Urea is highly soluble in solution of formaldehyde, even at ambient temperature and very quickly when heated. The dissolution…

This paper reports the equilibrium and kinetic parameters for N2 and CH4 adsorption on the zeolite H+ mordenite measured at 303 K and pressures up to 900 kPa using a dynamic column breakthrough (DCB) apparatus. The equilibrium capacities of mordenite measured for pure gases were 1.56 mmol/g CH4 and 0.85 mmol/g N2 at 9…
BM-21火箭炮是前苏联研制的一种122毫米40管自行火箭炮。该炮1964年开始装备陆军炮兵部队。1982年黎以冲突中，使用了BM-21火箭炮的两种型号，包括6管和9管两种。1984年，阿富汗战争期间，苏军大量使用了BM-21，主要用于袭击游击队村庄营地和实施火力封锁，建立安全区等。两伊战争中，双方使用BM-21火箭炮袭击对方境内目标。俄军在车臣冲突中，
A liquefaction process to convert waste plastic into fuel oil was studied over three commercial catalysts namely zeolite Y, Silica Alumina (SA) and fluid catalytic cracking (FCC) catalyst. A catalytic cracking process in which waste plastic were melted and cracked into smaller molecular weight hydrocarbons and at very…
