The rise of antibiotic resistance as a public health concern has led to increased interest in studying the ways in which bacteria avoid the effects of antibiotics. Enzymatic inactivation by several families of enzymes has been observed to be the predominant mechanism of resistance to aminoglycoside antibiotics such as…
Calcium carbonate was grown by diffusion of gaseous carbon dioxide into aqueous calcium chloride–alcohol solutions and the relationship between the alcohol additive and the growing crystal was investigated. There was no evidence that crystal growth was controlled through any specific molecular interaction between the…
We present theoretical and dynamic Monte Carlo simulation results for the mobility and microscopic structure of 1+1-dimensional Ising interfaces moving far from equilibrium in an applied field under a single-spin-flip ``soft'' stochastic dynamic. The soft dynamic is characterized by the property that the effects of ch…
The connections between the anti-shielding effect, negative absolute temperature and superluminal light propagation in both the instantaneously reversed electric field and the left-handed media are considered in the present paper. The instantaneous inversion of the exterior electric field may cause the electric dipole…
Building on the success of the first edition Fuel Cell Systems Explained presents a balanced introduction to this growing area. In summary, an altogether satisfying book that puts within its covers the academic tools necessary for explaining fuel cell systems on a multidisciplinary basis. Power Engineering Journal. An…
The structural, magnetic and electronic properties were investigated for LaAl1−xMnxO3 (x = 0.0, 0.005, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 1.0) perovskites prepared by the citrate method and calcined at 1073 K. The materials were characterised by XRD, BET surface area, diffuse reflectance spectroscopy (DRS), magnetic susce…
The third edition of this reference work represents a full revision by the author.It describes thermal and mechanical processes that produce extensive rearrangements of atoms in metals and alloys, and the resultant change in physical and chemical properties.Published as Parts I and II, it deals with lattice geometry,…
Kontakte anderer Art: ausschließlich cuprophile Wechselwirkungen wurden im [CuICl2]−-Dimer 2 nachgewiesen, das durch interne Reduktion des oktaedrischen CuII-Komplexes mit annähernd unbesetzten cis-Positionen, 1, entstand.
The chemical reactivity of a hydrogenated diamond surface with carboxylic acid [HCOOH, CH3(CH2)nCOOH (0 < n < 16)] in benzoyl peroxide containing solvent was investigated. The diamond surface modified with acetic acid was stable against severe conditions. The chemical reaction rate of the modification of the diamond s…
Epoxidation of 1-octene with hydrogen peroxide catalysed by amphiphilic salts of peroxo tungstophosphate [PO4[WO(O2)2]4]3- in water-in-oil microemulsions is an efficient and environmentally benign reaction which, coupled with ultrafiltration, shows the potential for continuous production of epoxides.
Abstract The electrochemical adsorption and hydrogenation of benzene on a roughened Pt electrode were studied by confocal Raman microscopy. Some forbidden vibrational bands of benzene were detected owing to the lowering of the symmetry upon adsorption. The results infer that benzene is adsorbed on the Pt surface in a…
Abstract Series of maleic mono‐ and diester monomers have been prepared by esterification of maleic anhydride with poly(ethylene glycol) having different molecular weights, and with n ‐dodecyl alcohol. These monomers were copolymerized with 2‐acrylamido‐2‐methylpropane sulfonic acid (AMPS) using different dose rates o…
Abstract Samples of polyglycolide were degraded in various buffered solutions in order to investigate the effects of buffer concentration, pH and particular buffer ions on the hydrolysis reaction. The small‐angle X‐ray scattering profiles changed with degradation; long periods were calculated and their changes with de…
Abstract Syntheses and biodegradation of statistical copolymers of D , L ‐lactide ( D , L ‐LA) with trimethylene carbonate (TMC), rac ‐1‐methyltrimethylene carbonate (1‐MTMC) and 2,2‐dimethyltrimethylene carbonate (2,2‐DTMC) were investigated at various monomer ratios using SmMe(C 5 Me 5 ) 2 THF as an initiator at 80…
In situ X-ray absorption fine structure (EXAFS) spectroscopy combined with on-line gas analysis was used to get insight into the oxidation state of the constituents and of the structure of a Pd/ZrO2 catalyst during activation and catalytic combustion of methane. The sample was prepared from an amorphous Pd33Zr67-alloy…
Abstract The thermal doping of the emeraldine base (EB) form of polyaniline using two different sulfonic acids, dodecylbenzene sulfonic acid (DBSA) and p ‐toluenesulfonic acid ( p TSA) has been studied. Differential scanning calorimetry was used to record thermal events associated with the doping process. EB undergoes…
Abstract Poly(ethylene terephthalate) (PET) is a widely used polyester, which can be crystallized from the melt over a wide range of supercooling conditions or, alternatively, quenched into the amorphous state and, subsequently, crystallized by thermal treatment above the glass‐transition temperature. It is well known…
A simple focused laser beam pruning method is used to fabricate unique two‐ and three‐ dimensional structures (see Figure and the cover), without a pre‐patterned substrate and under ambient conditions. The construction of microscopic movable carbon nanotube (CNT) structures that are controlled by laser light are also…
A 2D 10-element test microbolometer array was fabricated without an air-gap thermal isolation structure. The microbolometer uses vanadium oxide film deposited by pulsed laser deposition at room temperature as the infrared (IR) sensitive layer. The IR response of the uncooled microbolometer was evaluated in the spectra…
A novel, simple, fast, cheap and pollution-free method was developed for recovering the silver from waste X-ray photographic films with NaOH stripping. The method has a number of advantages because it obviates the need for burning, oxidizing, electrolysis or purifying steps. Moreover, all experiments were carried out…
