FeNi/V nanomultilayered films with different V layer thicknesses were synthesized by magnetron sputtering. By adjusting the thickness of the V layer, different interfacial compressive stress were imposed on FeNi layers and the effect of interfacial stress on martensitic transformation of the FeNi film was investigated…
P-glycoprotein is implicated in clinical drug resistance; thus, rapid quantitative analysis of its expression and activity is of paramout importance to the design and success of novel therapeutics. The scope for the application of quantitative imaging and image analysis tools in this field is reported here at "proof o…
Ternary alloyed II?VI group semiconducting CdSe x Te1???x thin films (x?=?0.1 to 1) have been fabricated using electrodeposition technique for detailed photoelectrochemical study and to eventually grow their two-dimensional microporous photonic structures using self-assembled template for optoelectronic devices. Band…
The development of the metrology and standards for advanced manufacturing of cellulosic nanomaterials (or basically, wood-based nanotechnology) is imperative to the success of this rising economic sector. Wood-based nanotechnology is a revolutionary technology that will create new jobs and strengthen America’s forest-…
Fuel cell is an excellent power generation source where electric current is generated with no environmental or noise pollution as the end product of the process is heat and water. This technology in which about six fuel cell types evolved in the pasted decade was base on the electrolyte used in each, and has a major l…
In this study, mixed southern hardwood was pretreated via a hydrothermal process at 160 C for 1 h. Alkaline pulping was then conducted on both the pretreated and original chips to prepare pulp with Kappa 17 and 30. For the Kappa 30 pulps, oxygen delignification was further carried out to render Kappa 17. After pulping…
Recently, there has been a lot of interest on transparent conducting oxide (TCO) materials which have common application in solar cells and some optoelectronic devices. In this work, cadmium oxide (CdO) thin films have been deposited on glass substrates by RF reactive magnetron sputtering technique and subsequently an…
In contrast to the predictions of the standard theory of electroconvection (EC), our experiments showed that the action of superposed ac and dc voltages rather inhibits pattern formation than favors the emergence of instabilities; the patternless region may extend to much higher voltages than the individual ac or dc t…
Spirooxazine-doped polymers exhibit a fast photochromism response and high polarization sensitivity after irradiation in the short-wavelength range. Based on such properties, holographic grating recordings accompanying a linearly polarized blue-violet beam (405 nm) in a photochromic film were performed by two coherent…
Crystalline Si-C thin films were prepared at substrate temperature between 200°C and 1000°C using Thermionic Vacuum Arc (TVA) method. To increase the acceleration potential drop a negative bias voltage up to -1000V was applied on the substrate. The 200nm thickness carbon thin films was deposed on glass and Si substrat…
We present a systematic study on hydrogenated silicon $m$ vacancies above saturation. For each system a global geometry optimization search for low-lying local minima is performed using a newly developed SiH tight binding model. Subsequently a large number of low-energy structures are examined by density functional ca…
Inspired by natural multifunctionality, mimumes are microfibrous multifunctional metamaterials. Their microfibrosity engenders multifunctionality. Poly(p-xylylene) polymers that are currently used in bulk non-fibrous forms for packaging and tribological applications in electronic and biomedical arenas are excellent in…
A series of high quality Yb3+-doped gadolinium scandium gallium garnet (Yb:GSGG) single crystals with different Yb3+ ion concentration (7.5, 10, 15 and 30 at.%) has been grown by means of optical floating zone (OFZ). Crystal structure was analyzed with X-ray powder diffraction (XRPD), showing that the Yb:GSGG crystal…
TamB is a recently described inner membrane protein that, together with its partner protein TamA, is required for the efficient secretion of a subset of autotransporter proteins in Gram-negative bacteria. In this study, the C-terminal DUF490963-1138 domain of TamB was overexpressed in Escherichia coli K-12, purified a…
Magnetic and transport properties are investigated in Pr0.5Sr0.5Mn1−xCr x O3 (0 x 0.05) focusing on the effect of Cr substitution and particle size dependence. The studies demonstrate that magnetic and transport properties are significantly different for nanocrystalline compound from the bulk. Neutron depolarization a…
IN THE MIDST OF THE EPITAXIAL CIRCUITRY REVOLUTION IN SILICON TECHNOLOGY, WE LOOK AHEAD TO THE NEXT PARADIGM SHIFT: effective use of the third dimension - in particular, its combination with epitaxial technology. We perform ab initio calculations of atomically thin epitaxial bilayers in silicon, investigating the fund…
Organic solar cells using titanylphthalocyanine as a hole transport layer (HTL) were fabricated and characterized. Photovoltaic properties of the solar cells with inverted structures were investigated by optical absorption and current density–voltage (J–V) characteristic. The titanylphthalocyanine was mainly used as a…
Flower-like layered titanate nanosheets were synthesized by a solvothermal reaction that directly used tetrabutyl titanate as a titanium source and poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) as a stabilizer in acetic acid solution. The layer number of each nanosheet varied from 6 to…
To explore potential applications, MgNb2O6 single crystal grown previously by optical floating zone method was used as a prototype for optical phonon behavior investigation.

Elongation factor P (EF-P) plays an essential role in the translation of polyproline-containing proteins in bacteria. It becomes functional by the post-translational modification of its highly conserved lysine residue. It is first β-lysylated by PoxA and then hydroxylated by YfcM. In this work, the YfcM protein from E…
