First principles total energy calculations have been performed using the full potential linear augmented plane wave plus local orbital (FP-LAPW+lo) method within density functional theory to investigate the effects of Sr-dopant on the structural, electronic, and optical properties of Mg1-xSrxTe alloys in the rock salt…
Three irradiation positions of Apsara reactor were characterized by determining epithermal neutron spectrum shape factor$(\alpha)$and sub-cadmium to epithermal neutron flux ratio$(f)$for${\rm k}_{0}$-based Internal Monostandard Neutron Activation Analysis (IM-NAA). The$\alpha$values were determined by cadmium ratio me…
Creating a pyramidal structure on an n-GaN surface is considered the most effective approach for maximizing light extraction of n-side-up GaN-based light-emitting diodes (LEDs). This letter shows that the light extraction efficiency of a pyramidal n-GaN surface can be further enhanced by growing ZnO nano-rods (NRs) sp…
In this work, a novel amperometric biosensor for hydrogen peroxide (H2O2) determination was successfully prepared by immobilizing horseradish peroxidase (HRP) on poly (aniline-co-o-aminobenzoic acid) or p (Ani-co-o-Aba) and then covered with chitosan (CS) film. The immobilized HRP displayed an excellent electrocatalyt…
Extended abstract of a paper presented at Microscopy and Microanalysis 2013 in Indianapolis, Indiana, USA, August 4 – August 8, 2013.
Tumor cell apoptosis by using nanosecond pulsed electric fields (nsPEF) has a great potential in clinical tumor treatment. It is difficult to find the appropriate parameters of nsPEF which can induce substantial apoptotic tumor cells because of selectivity between apoptosis and parameters of pulse number and pulse dur…
BACKGROUND: Radiologic response of brain tumors is traditionally assessed according to the Macdonald criteria 10 weeks from the start of therapy. Because glioblastoma (GB) responds in days rather than weeks after boron neutron capture therapy (BNCT) that is a form of tumor-selective particle radiation, it is inconveni…
Heating of zinc(II) nitrate and 2,5-thiophenedicarboxylic acid (H 2 Tdc) in the presence of hexamethylenetetramine in N -methylpyrrolidone (Nmp) gave the crystals of a layered coordination polymer [Zn 2 (Nmp) 2 (Tdc) 2 ] · 2Nmp · 0.5H 2 O, which were studied by X-ray diffraction. The compound was characterized by IR s…
Die attach process is widely used to realize the connection between die, device and the rest of the system in electronic packaging. During this process, the die moves under the capillary force induced by the liquidus solder. Such a die tilt phenomenon usually occurs and strongly worsens the reliability and performance…
PREMISE OF THE STUDY: Tamale preparation has a long tradition in Mexico. To understand which material properties have been considered important for this purpose throughout the years, a study was conducted of the anatomical, chemical, and mechanical properties of the leaves of four plant species used in tamale preparat…
The density functional theory with account for gradient correction (DFT/PBE) and periodical boundary conditions was used to model the main stages of processes occurring in hydrogen low-temperature fuel cells. Modeling was carried out at the example of calculation of catalytic anodic and cathodic processes occurring on…

The process of coagulation of suspensions of monodisperse spherical silica particles driven by appropriate coagulants (NH4Cl, HCl, C16H33N(CH3)3Br) has been studied. Films of photonic crystals and photonic glasses have been grown by the sedimentation method. The possibility of controlling the degree of structural diso…
The aim of this paper is to recognize if the differences between effects due to external mechanical faults and internal electrical faults in induction motors can be diagnosed through Motor Current Signature Analysis (MCSA) techniques applying Fourier analysis. For that purpose an alternative algorithm to traditional F…
The effect of stress on the oxidation behavior of solution-annealed Alloy 600 was investigated by exposing samples to low pressure steam environments containing hydrogen at temperatures up to 480°C. The resultant oxidized surfaces of stressed and unstressed samples were analyzed via several electron microscopy techniq…
High-accuracy solution of the problem of plate analysis is normally required in some pre-known domains (regions with the risk of significant stresses that could potentially lead to the destruction of structure, regions which are subject to specific operational requirements). The distinctive paper is devoted to correct…
Abstract This article summarizes the terminology for gas reactions, and discusses low-temperature nitriding and nitrocarburizing of stainless steels. It describes the various nitriding processes, namely, high- and low-pressure nitriding, oxynitriding, sulfonitriding, oxysulfonitriding, ferritic nitrocarburizing and au…
Reported cases of the influence of guest molecules absorption/desorption on magnetic properties of porous coordination polymers (PCP) of transition metals are reviewed. Interaction of PCPs with guest molecules can modify magnetic susceptibility in wide temperature range, as well as can lead to change of the magnetic o…
Organic content in soil is believed to inhibit formation of reaction products in lime stabilization which resulted in low gain of strength when dealing with organic soils. Zeolite, a kind of pozzolan with high CEC capacity is proposed to be use in this study in order to improve lime stabilization of organic soil. The…
An analytical treatment of the piezoelectric ceramic complete ring transducer undergoing flexural vibrations is presented. Conditions for the electromechanical excitation of the flexural vibrations are discussed and it is shown that the fundamental mode of the flexural vibration of a complete ring can be considered as…
