9-R-Anthracenes (R = Me, Ph) are effective acceptors of peroxyl and metalalkoxyl radicals in the systems tert -butylhydroperoxide-metal tert -butoxide (M = Al, V, Cr; C 6 H 6 , 20°C). Isolation of 9-R-9,10-dihydro-9,10-di- tert -butylperoxyanthracenes, 10-R-10- tert -butylperoxy-9-anthrones as major products reliably…
The transmission-reflection spectra of a bilayer structure formed on a substrate of single-crystal silicon with transition layers (TiO 2 -SiO 2 ), which consists of a PbZr 0.52 Ti 0.48 O 3 ferroelectric thin film and a polycrystalline platinum layer, have been measured in the frequency range of 10–6000 cm −1 . The fre…
Powders of the ferrimagnetic alloy CoFeBDyPr have been synthesized by the gas atomization method. Annealing of the samples at 900°C leads to the recrystallization of the amorphous phase into the crystalline phase (Pr,Dy) 2 Fe 7 Co 7 B, which changes the magnetic properties of the alloy (the coercive force decreases, t…
The Src family of tyrosine kinases (SFKs) regulate numerous aspects of cell growth and differentiation and are under the principal control of the C-terminal Src Kinase (Csk). Although Csk and SFKs share conserved kinase, SH2 and SH3 domains, they differ considerably in three-dimensional structure, regulatory mechanism…
In this work, we demonstrate the results of studies on the synthesis, the structure and properties of carbon inverted opal (C-IOP) nanostructures, the surface of which is modified by oxide and sulfide of nickel. It is shown that the modification of the matrix C-IOP by nickel compounds led to a decreasing the specific…
Wide band gap oxides, such as ZnO, SnO2 and ZrO2, are functional materials with a wide range of applications in several important technological areas such as those including lighting, transparent electronics, sensors, catalysis and biolabeling. Recently, doping and co-doping of oxides with lanthanides have attracted a…
In this work, it was examined mechanisms that control internal cooling device (nano-homojunction diode)depending on thermoelectric Peltier effect, resulting in structures that are optimized thermal management. Peltier coefficient for short-length diode is theoretically investigated. It is found that the cooling power…
The influence of blending Li1.2Mn0.54Ni0.13Co0.13O2 with a small amount of Na0.6[Li0.2Mn0.8]O2 on the electrochemical properties has been investigated. The results indicate that Na0.6[Li0.2Mn0.8]O2 has a beneficial effect on the electrochemical performance of Li1.2Mn0.54Ni0.13Co0.13O2. The initial coulombic efficiency…
If it is needed to achieve a higher strain rate during the ironing process, which is possible without inter-stage annealing, the ironing is performed in succession through multiple dies. During that process, changes of friction conditions occur due to the change of contact conditions (dislodging of lubricants, changes…
Background: Stem cells represent an ideal cell source for application in tissue engineering and regenerative medicine due to their ability to proliferate and differentiate to a wide variety of cell lineages. With recent development of medical sciences and tissue engineering, usage of adipose-derived mesenchymal stem c…
Toyota Motor Corporation and the Japan Fine Ceramics Center (JFCC) have developed a new observation technique that allows researchers to monitor the behaviour of nanometre-sized particles of platinum during chemical reactions in PEM fuel cells, so that the processes leading to reduced catalytic reactivity can be obser…
This paper presents an accurate and efficient model for crosstalk analysis of coupled multi-layer graphene nanoribbon (MLGNR) interconnects using a finite-difference time-domain (FDTD) method. In a more realistic manner, the proposed model incorporates the width dependent mean free path (MFP) parameter that helps in a…
Clothes are exposed to diff erent impacts during usages and maintenance. The more frequent impacts on textile materials are the washing processes and the perspiration eff ects. These mentioned eff ects are the causes of specifi c changes of the textile fi bres and on colour reproduction on printed materials. This pape…
Doping Cu(In,Ga)Se2 (CIGS) thin films with Sb can provide large grains at lower processing temperatures than are normally required. In this study, we incorporated Sb into the precursor of a two-step selenization process. We saw enhanced grain size and improved device performance compared to similarly processed CIGS fi…
We developed a 2D numerical model simulating cathodoluminescence (CL) measurements in CdTe. Using this model we analyze how various material parameters impact the CL contrast and intensity observed in the measured signal, and determine if and when we can accurately determine the value of grain boundary recombination r…
Bifacial n-type c-Si solar cells have recently gained a lot of attention in the photovoltaic field. Such architecture at cell level is employed in the n-Pasha concept. At module level n-Pasha are combined with a reflective white backsheet to avoid losses from infrared transmission. In this work we have investigated th…
Polyhydroxyalkanoates (PHAs) are a family of biopolymers with good biodegradability. Poly(3hydroxybutyrate) [P(3HB)], poly (3-hydroxybutyrate-co-25 mol % 4-hydroxybutyrate) [P(3HBco-25 mol % 4HB)] and poly (3-hydroxybutyrate-co-75 mol % 4-hydroxybutyrate) [P(3HB-co-75 mol % 4HB)] were fabricated using the electrospinn…
Abstract The polymer composite materials properties are clearly determined by their constituent properties and by the micro-structural configuration. Additives and modifiers ingredients can expand the usefulness of the polymeric matrix, enhance the processability or extend composite durability. The fibres are mainly r…
A study on synthesis and characterization of nanoporous carbon derived from sugarcane bagasse (Saccharum officianarum) by ultrasonik irradiation using ZnCl2 activator for electrochemical capasitor application has been investigated. Nanoporous carbon is a basic material for the electrode in the electrochemical energy s…
Nano-composite copper-zinc oxide (NCCZO) was deposited on borosilicate glass using a novel sol-gel/doctor-blade technique. The photocatalyst was prepared from copper acetylacetonate, zinc acetylacetonate, monoethanolamine (MEA) and citric acid monohydrate at 75 oC, aged for 1 d and annealed at 650 oC. The properties o…
