The anomalous piezoresistance (a-PZR) effects, including giant PZR (GPZR) with large magnitude and inverse PZR of opposite, have exciting technological potentials for their integration into novel nanoelectromechanical systems. However, the nature of a-PZR effect and the associated kinetics have not been clearly determ…
The aim of the current study was to analyze the differential microRNA (miRNA) expression profiles of human epidermal stem cells (ESCs) and differentiated keratinocytes. Enzyme digestion was used in combination with rapid adhesion to collagen IV to isolate primary human ESCs and differentiated keratinocytes, from which…
Three new Zn(II) complexes, [Zn(ox)(imb)] (1), [Zn2(mal)2(imb)2] (2), and [Zn(suc)(imb)]·H2O (3) (imb = 2-(1H-imidazolyl-1-methyl)-1H-benzimidazole, H2ox = oxalic acid, H2mal = malonic acid, H2suc = succinic acid), have been synthesized and structurally characterized. Complex 1 is a 3-D framework with a 4-connected di…
Strontium titanate ( SrTiO 3 ) is a potential photocatalyst of H 2 evolution for providing green energy. One of the main strategies for increasing the efficiency of H 2 evolution is to increase the surface area of photocatalysts. In this study, spray pyrolysis was used because of its superior flexibility in morphologi…
Multiple enzyme mixtures are attractive for the production of many compounds at an industrial level. We report a practical and novel approach for coimmobilization of two enzymes. The system consists of a silica microsphere core coated with two layers of individually immobilized enzymes. The model enzymes α-amylase (AA…
Aiming to understand the effect of a metal surface on nonlinear optical properties and the combined effects of surface and solvent environments on such properties, we present a multiscale response theory study, integrated with dynamics of the two-photon absorption of 4-nitro-4'-amino-trans-stilbene physisorbed on nobl…

We report a straightforward method for the rapid conversion of thio-ethers to thio-acetates using TiCl4, in good to excellent yields. The reaction conditions tolerate a variety of functional groups, including halide, nitro, ether, thiophene and acetylene functionalities. A catalytic variant of this reaction is also de…
The accelerated pace of the semiconductor industry in recent years is putting a strain on existing dimensional metrology equipment (such as critical dimension-secondary electron microscopy, atomic force microscopy, scatterometry) to keep up with ever-increasing metrology challenges. However, a revolution appears to be…
Abstract The structures and stabilities of 1,8-anthrylene cyclic oligomers having acetylene or diacetylene linkers were investigated by DFT calculations with M05 and M06 series functionals. The structures of the cyclic oligomers were reasonably reproduced at the M05-2X/6-31G* level by using the interlayer distance bet…
Surface functionalization of an inorganic surface with bio-organic molecules is often aimed at creating a "permanent" bio-organic surface with receptor functional groups. We show here that L-cysteine can be used to transform a highly reactive Si(111)7×7 surface to not just a permanent bio-organic surface but also a se…
Conformational changes in the β2α2 and β6α6 loops in the alpha subunit of tryptophan synthase (αTS) are important for enzyme catalysis and coordinating substrate channeling with the beta subunit (βTS). It was previously shown that disrupting the hydrogen bond interactions between these loops through the T183V substitu…
Tumor-associated angiogenesis is triggered by multiple angiogenic factors. Vascular endothelial growth factor blockers are currently a major mechanism of angiogenesis inhibition; however, either insensitivity due to the targeting of single angiogenic factors or serious side effects due to non-specific exposure ultimat…
Properties of metallic materials are intrinsically determined by their electron behavior. However, relevant theoretical treatment involving quantum mechanics is complicated and difficult to be applied in materials design. Electron work function (EWF) has been demonstrated to be a simple but fundamental parameter which…
To increase the lifetime of rocket combustion chambers, thermal barrier coatings (TBC) may be applied on the copper chamber wall. Since standard TBC systems used in gas turbines are not suitable for rocket-engine application and fail at the interface between the substrate and bond coat, a new bond-coat material has to…
AbstractIn the literature, much attention has been focused on power system harmonics. One of its important effects is degradation of the load power factor. In this article, a C-type filter is used for reducing harmonic distortion, improving system performance, and compensating reactive power in order to improve the lo…
Photocatalysis is being intensively studied for reactions such as water splitting and CO 2 reduction, where absorption of light in a semiconductor such as TiO 2 produces electrons and holes that can drive chemical reactions. Efficiencies on bulk materials, however, are too low to be of practical use. In recent years,…
Microstructural features of sintered steels, which comprise both phases and porosity, strongly condition the mechanical behaviour of the material under service conditions. Many research activities have dealt with this relationship since better understanding of the microstructure–property correlation is the key of impr…
A soft ground arresting system (SGAS) is an alternative solution on airport runways where the runway safety area (RSA) does not meet international Federal Aviation Administration (FAA) standards. If an SGAS is installed on both ends of the runway, the length of the runway can be shortened. In this paper the options of…
Protein phase behavior is involved in numerous aspects of downstream processing, either by design as in crystallization or precipitation processes, or as an undesired effect, such as aggregation. This work explores the phase behavior of eight monoclonal antibodies (mAbs) that exhibit liquid-liquid separation, aggregat…
