The lightness of magnesium makes it an attractive material for applications where weight reduction is critical, in particular, consumer electronics and transportation industries. Despite its advantages as a material the use of magnesium worldwide is a tiny fraction of other materials (steel, plastic, aluminium). Among…
Abstract Bis(tetrabutylammonium)bis(2‐thioxo‐1,3‐dithiole‐4,5‐dithiolato)mercurate(II) was prepared and characterized by elemental analyses, electronic absorption, infrared and X‐ray powder diffraction spectroscopy. The specific heat of the crystal was measured to be 1878.2 J.mol –1 K –1 at 300 K. The thermal decompos…
The beneficial aspects of enhanced or extended heat transfer surfaces may be offset if operated under fouling conditions. In this article, preliminary experimental results for crystallization fouling of CaSO4 solutions onto surfaces with different structures are reported. Flat stainless steel plates (50 mm × 59 mm) wi…
We have studied the thermal stability of five potassium strontium vanadates: KSr(VO 3 ) 3 , K 2 Sr(VO 3 ) 4 , K 4 Sr(VO 3 ) 6 , K 6 Sr(VO 3 ) 8 , and KSrVO 4 . The double orthovanadate undergoes a reversible polymorphic transformation at 1117°C and is stable up to 1500°C. The double metavanadates melt peritectically i…
The bacterial tyrosine phenol-lyase (EC 4.1.99.2) and tryptoptophan indole-lyase (EC 4.1.99.1) belong to pyridoxal-5'-phosphate dependent beta-eliminating lyases, catalysing the reversible decomposition of L-tyrosine and L-tryptophan to pyruvate, ammonia, and phenol or indole correspondingly. Data on the three dimenti…
The temperature dependence of the initial magnetic susceptibility of a quenched equiatomic FePd alloy with an A 1 structure and the variations of its Curie temperature and anisotropy of hysteresis loops have been studied during the ordering annealing of single-crystal samples at 550°C. The micro- and mesostructure, re…

The enthalpy of the subsystem of silver ions in the intercalation compounds Ag x TiS2 has been calculated from the electrochemically measured thermodynamic functions of the silver subsystem. The ionic conductivity and the coupled chemical diffusion coefficients for silver in the intercalation compound have been measur…
In this paper, we present the results of a systematic study directed toward submicrometric scale triboactivity of a range of hydrogenated diamond-like-carbon (H : DLC) films derived from source gases with different hydrogen-to-carbon ratios. The H : DLC films were deposited on Si substrates in a plasma enhanced chemic…
The x-ray storage-phosphor CsBr:Eu2+ has been found to exhibit a strong increase in photostimulated-luminescence (PSL) intensity following hydration at room temperature. The sensitivity increases by a factor of 25 following a 60 min exposure to an atmosphere of 99% relative humidity, which is considered to be due to a…
We report the position-controlled formation and the growth direction control of MnAs nanoclusters (NCs) on partially SiO 2 -masked GaAs (111)B substrates by selective-area metal–organic vapor phase epitaxy (SA-MOVPE). At a relatively low growth temperature of 750 °C, MnAs NCs were grown not only in the opening regions…
Global environmental regulations are changing the leather industry. Conventional unhairing contributes most of the pollution in the industry, such as hydrogen sulfide and lime. Ever-increasing attention to the environmental impact of the leather industry has necessitated the development of enzymatic unhairing as a pot…
Photo-stability measurements of electro-optic polymer inverted ridge waveguides, fabricated from AJ-CKL1, AJ416 and LPD-80, are conducted up to 30, 100, and 100 mW of input power coupled into the waveguides respectively. These experiments are performed in a N2atmosphere to exclude absorbed O2. AJ416 and LPD-80 are fou…
Thermodynamics and kinetics of adsorption of atoms and molecules by carbon nanotubes are investigated. Expressions are derived that can be used to perform calculations taking into account various external factors and interactions and, therefore, analyze both physical and chemical adsorption processes and determine its…
Abstract Silver nanoparticles were obtained by a chemical reduction method using aqueous polymers as dispersant and characterized by UV‐Vis spectroscopy, transmission electron microscopy (TEM) and light‐scattering spectroscopy. Solid polymer films containing the silver nanoparticles were also prepared after evaporatin…
As semiconductor devices shrink in size, the challenge of characterisation of their dopant distributions intensifies. Scanning electron microscopy (SEM) has been proposed as a suitable technique to overcome this challenge. However, current low-voltage (LV) SEMs are incapable of the probe sizes required for nano-scale…
The work we present in this article is an investigation of the optimal dielectric behaviour of a ternary composite based on a mixture of epoxy resin, titanates and oxides. Titanates are known by their capacity to provide high dielectric constant values that make their use very important in system of telecommunication,…
Predicting electronic-band structures is a key issue in understanding the properties of materials or in materials design. In this review article, application examples of first-principles calculations, which are not based on adjustable empirical parameters, to study electronic structures of organic conductors are descr…
Magnetic nano- and microparticles have already found many important applications in various areas of biosciences, medicine, biotechnology, environmental technology etc. These smart materials exhibit different types of response to external magnetic field. In most cases they can be described as composite materials, wher…
Nanoporous materials such as zeolites and mesoporous silica crystals have attracted a lot of attention in recent years. In particular, the incorporation of various materials such as organic molecul ...
