This Perspective highlights studies of protein structure, stability, and folding kinetics that can now be carried out in prokaryotic and eukaryotic cells. The general features of cooperative folding transitions and kinetics remain the same as those in vitro, but the folding free-energy landscape and local viscosity va…
Power Quality means to maintain purely sinusoidal current wave form in phase with a purely sinusoidal voltage wave form. Power quality improvement using traditional compensation methods include many disadvantages like electromagnetic interference, possible resonance, fixed compensation, bulkiness etc. So power system…
Information relating to the biology, culture expansion, and mechanisms relating to adipose-derived cells has advanced significantly in the past decade. Both the heterogeneous stromal vascular fraction (SVF) and more homogeneous adipose-derived stem cells (ASC) offer unique opportunities as novel cell-based therapeutic…
The enthalpy of formation of 5,6-(3,4-furazano)-1,2,3,4-tetrazine-1,3-dioxide was determined, and the parameters of detonation, energetics, and performance characteristic were estimated.
We present full-band structure calculations of temperature- and wavelength-dependent two-photon absorption coefficients and free-carrier absorption cross sections in GaAs, InP, and 0.92 eV-band gap Ga64In36As and InP60As40 alloys. The calculated coefficient decreases with increasing wavelength and band gap but increas…
In the nanoscale beam, the effect of the coupling between temperature and strain rate becomes domineering. In the present study, a generalized solution for the vibration of gold nano-beam resonator induced by ramp type heating is developed in the context of the Green and Naghdi model of generalized thermoelasticity. T…
Single crystalline anatase TiO 2 tetragonal nanosheet‐array film on a transparent conductive fluorine‐doped tin oxide (FTO) substrate was successfully prepared by hydrothermal method. The products were characterized with XRD, SEM, and transmission electron microscopy measurements. The formation mechanism of the tetrag…
Drastic efforts have been realized these last years in order to develop comple mentary organic technology. This is the essential key to produce elementary low cost circuits for digital and analog applications. Different techniques are available nowadays to obtain both Nand/or P-type organic devices. Screen printing is…
The HELIOS zero-dimensional code (Version 1.0) is described in detail in the case of deuterium-tritium (D-T) plasmas.The part of the code described solves in a self-consistent way the thermal equilibrium equation of a D-T thermonuclear plasma coupled to the conservation equation of the helium ash with a τHe*/τE = cons…
One of the challenges in the field of organic photovoltaics is developing alternatives to the family of fullerene derivatives that are commonly used as acceptor material but that generally lack strong optical absorption coefficient. We describe the synthesis and optoelectronic properties of three new acceptor electron…
Nanocrystalline zeolite has received significant attention in the catalysis community. Zeolites with a crystal size smaller than 100 nm are the potential replacement for existing zeolite catalysts due to its unique features with added advantages. Zeolite FAU type Y is one of the most studied framework of all zeolites,…

The MWCNT/TiO2 composite was homogeneously coated on the surface of GCE and applied in the electrochemical determination of 0.1 mM potassium ferricyanide in 0.1 M Na2HPO4 (pH 8.5). The redox couple of potassium ferricyanide with current enhancements of 3.0-3.1 folds was obtained using the MWCNT/TiO2/GCE when compared…
We systematize available experimental data on the crystal structure of the ternary halides K 2 (Rb 2 ,Cs 2 ,Tl 2 )TeBr 6 (I 6 ) and Rb 3 (Cs 3 )Sb 2 (Bi 2 )Br 9 (I 9 ), analyze the general trends in the properties of their single crystals, and examine the key features of the physicochemical interaction in related syst…
PURPOSE: To design and evaluate a four-channel cardiac transceiver coil array for functional cardiac imaging at 7T. MATERIALS AND METHODS: A four-element cardiac transceiver surface coil array was developed with two rectangular loops mounted on an anterior former and two rectangular loops on a posterior former. specif…
A systematic analysis of orthophosphates of framework (tetrahedral-octahedral) structure, belonging to langbeinite structural type (cubic cell, space group P213), is performed. The langbeinite structure is considered as favorable for environmentally safe crystalline forms of radioactive waste solidification. Experimen…
AlGaN ternary alloys have unique properties suitable for numerous applications due to their tunable direct band gap from 3.4 to 6.2 eV by changing the composition. Herein we report a convenient chemical vapor deposition growth of the quasi-aligned Al(x)Ga(1-x)N alloy nanocones over the entire composition range. The na…
A review of various laser techniques for microscale processing of SiC for microelectronics and microelectromechanical-system applications is presented. SiC is an excellent material for harsh environments due to its outstanding mechanical, thermal, and chemical properties. However, its extreme thermodynamic stability a…
It is generally believed that there is no simple relationship between ultimate fracture strength and stiffness for an elastically isotropic material. By taking bulk metallic glasses (BMGs) as model materials, the relation between ultimate fracture strength and elastic moduli was analyzed within Griffith theory framewo…
