ABSTRACT Hydrogen is known to have a deleterious effect on most engineering alloys. It has been shown repeatedly that the strength of steels is inversely related to the ductility of the material in hydrogen gas. However, the fatigue properties with respect to strength are not as well documented or understood. Here, we…
In this paper, a novel green phosphor Ca 8 Mg 3 Al 2 Si 7 O 28 :Eu 2+ is synthesized via a conventional high‐temperature solid‐state reaction. The crystal structure of the phosphor is confirmed from the Rietveld method. The obtained phosphor has a wide absorption band from the UV to the visible spectral region, rangin…
A urea-based tripodal receptor L substituted with p-cyanophenyl groups has been studied for halide anions by $^1$H NMR spectroscopy, density functional theory (DFT) calculations and X-ray crystallography. The $^1$H NMR titration studies suggest that the receptor forms a 1:1 complex with an anion, showing the binding t…
Patchy particles are a popular paradigm for the design and synthesis of nanoparticles and colloids for self-assembly. In "traditional" patchy particles, anisotropic interactions arising from patterned coatings, functionalized molecules, DNA, and other enthalpic means create the possibility for directional binding of p…
Engineering multifunctional nanocarriers for targeted drug delivery shows promising potentials to revolutionize the cancer chemotherapy. Simple methods to optimize physicochemical characteristics and surface composition of the drug nanocarriers need to be developed in order to tackle major challenges for smooth transl…
An analytical model for the prediction of the dielectric properties of gold–silver alloys is developed. This multi‐parametric model is a modification of the usual Drude–Lorentz model that takes into account the band structure of the metals. It is fitted by a genetic algorithm to the dielectric function of thin alloy f…
The peak fluorescence emission of conventional fluorophores such as organic dyes and inorganic quantum dots is independent of the excitation wavelength. In contrast, the position of the peak fluorescence of graphene oxide (GO) in a polar solvent is heavily dependent on the excitation wavelength. The present work has d…
We demonstrate extraordinary photoconductive behavior in two-dimensional (2D) crystalline indium selenide (In2Se3) nanosheets. Photocurrent measurements reveal that semiconducting In2Se3 nanosheets have an extremely high response to visible light, exhibiting a photoresponsivity of 3.95 × 10(2) A·W(-1) at 300 nm with a…
The synthesis of a DO3A conjugate of [(p-aniline benzothiazole)methyl]pyridine (<TEX>$L^2H_3$</TEX>) and its gadolinium complex of the type [<TEX>$Gd(L^2)(H_2O)$</TEX>] (<TEX>$GdL^2$</TEX>) is described. The <TEX>$R_1$</TEX> relaxivity (<TEX>$=4.50mM^{-1}sec^{-1}$</TEX>) and kinetic inertness of <TEX>$GdL^2$</TEX> com…

Although nanoprobes functionalized with one type of affinity molecule are commonly used as bioimaging probes, biolabeling studies of nanoprobes functionalized with more than one type of affinity molecule remains an unexplored area of research. Here we show that the labeling specificity of a nanoprobe can be enhanced i…
Purpose – The purpose of this paper is to investigate the effects of the related factors on the mean path length of the Epstein frame and propose a weighted method based on the different specific losses to decide the actual mean path length of the Epstein frame. Design/methodology/approach – Two Epstein frames of diff…
We investigate charge transport of a randomly stacked few-layer graphene (FLG) film supported on quartz plate, as-prepared and after annealing treatment. The film is prepared by a simple, cheap and rapid hot spray technique from a FLG suspension, while FLG was obtained in our previous report by high yield mechanical e…
Purpose – The purpose of this paper is to present a simple method to analyze the iron loss in the laminated core of power and distribution transformers. Design/methodology/approach – This paper presents a practical method to calculate the no-load loss in the transformer cores. Considering the non-uniformity of the mag…
How garments contribute to performance of the clothing system during wear is of interest, as is understanding the value of using fabric properties to inform end-use characteristics. To investigate the influences of layering upper-body garments, four fabrics were used to construct two first-layer garments (wool and pol…
The well dispersed and size-controlled Ag nanoparticles decorated multi-walled carbon nanotubes (MWCNT) were synthesized by a simple chemical plating method. The oxidized MWCNT surfaces could get a more controlled and specific nucleation of Ag nanoparticles. The as-prepared nanocomposites were characterized by transmi…
Nanomaterials are prone to influence by chemical adsorption because of their large surface to volume ratios. This enables sensitive detection of adsorbed chemical species which, in turn, can tune the property of the host material. Recent studies discovered that single and multilayer molybdenum disulfide (MoS_2) films…
Carboxymethyl-quaternized oligochitosan (CMQAOC) was prepared through carboxymethylization and N-quaternization of oligochitosan (OC) which was obtained from chitosan degradation. The structure was confirmed by Fourier transform infrared spectroscopy (FT-IR), 1H-NMR, and X-ray diffraction (XRD) analysis. The performan…
4-Hydroxy-4-methyl-2-oxoglutarate (HMG)/4-carboxy-4-hydroxy-2-oxoadipate (CHA) aldolases are class II (divalent metal ion dependent) pyruvate aldolases from the meta cleavage pathways of protocatechuate and gallate. The enzyme from Pseudomonas putida F1 is structurally similar to a group of proteins termed regulators…
Ga-Sb alloys with compositions ranging between ∼12 and 50 at. % Ga are promising materials for phase change random access memory applications. The short-range structures of two such alloys with compositions Ga14Sb86 and Ga46Sb54 are investigated, in their amorphous and crystalline states, using 71Ga and 121Sb nuclear…
