ZnO thin films have been successfully deposited by Atomic Layer Deposition (ALD) using Diethylzinc (DEZn) and water (H2O) as precursors. The preferred orientations of the thin films were found to be strongly dependent on the deposition temperature. (100)–oriented ZnO thin films were grown in the temperature range of 1…
An application of deuteride moderator for fast reactor cores is proposed for power flattening that can mitigate thermal spikes and alleviate the decrease in breeding ratio, which sometimes occurs when hydrogen moderator is applied as a moderator. Zirconium deuteride is employed in a form of pin arrays at the inner mos…
We present here the results of the Raman study of lattice dynamics and local compositional fluctuations in cubic spinel Zn2TiO4 nanostructures. The observed Raman modes of the spinel structure are identified and attributed to local vibrational modes. Additionally, the analysis of the nonpolar E2(H) (∼437 cm−1, 54.2 me…
A new trivalent chromium black plating based on trivalent chromium and cobalt metal has been optimized both in the as plated as well as annealed conditions. The annealed coatings exhibited high hardness, good corrosion resistance and optical properties. XRD and SEM investigations confirmed the formation of intermetall…
Three novel hydroxylated tung oil (HTO) components with three conjugated double bonds were synthesized by aminolysis of tung oil with diethylolamine, and their cytotoxic effects on five human tumor cell lines were revealed for the first time. Compared with conjugated linolenic acid (CLnA) and conjugated linoleic acid…
In this study, we report a facile one-step solvothermal approach for growing nanoparticle aggregates–texture nanosheets hierarchical TiO2 core–shell structure (HTCSS) via the synergistic interaction of butylamine and ethanol. Under specific conditions, the products obtained in ethanol tended to aggregate into spherica…
Pore propagation during anodization of (100) n-InP electrodes in aqueous KOH was studied in detail by scanning and transmission electron microscopy (SEM and TEM). Pores emanating from surface pits propagate along the 〈111〉A crystallographic directions to form, in the early stages of anodization, porous domains with th…
A straightforward non-covalent synthetic strategy for producing donor-acceptor rotaxanes is reported. Femtosecond absorption spectroscopy illustrates that the use of this strategy gives rise to supramolecular chromophores with different electron transfer behavior.
Love's model for the acoustic scattering by a spherical viscous fluid shell filled with gas and surrounded by inviscid liquid [J. Acoust. Soc. Am. 64, 571-580 (1978)] is reviewed. For certain material parameters, discrepancies are observed in Love's scattering cross section when compared with the exact solution near r…
A prototypical ferritic/martensitic alloy, HT-9, of interest to the nuclear materials community was investigated for microstructure effects on Barkhausen noise emission and first-order reversal curve (FORC) analysis for three different heat-treated samples. It was observed that Barkhausen noise emission and reversible…
Intrinsic disorder is everywhere and is inevitable. The non-folding propensity is inherent for numerous natural polypeptide chains, and many functional proteins and protein regions are intrinsically disordered. Furthermore, at particular moments in their life, most notably during their synthesis and degradation, all o…
We have recently proposed a new general concept regarding amphiphilic materials that have been named as "active interfacial modifier (AIM)." In emulsion systems, an AIM is essentially insoluble in both water and organic solvents; however, it possesses moieties that are attracted to each of these immiscible liquid phas…
We report two new microporous mixed-metal triazolate based MOFs made from zinc and nickel salts combined with either 1,2,4-triazole or 3,5-diamino-1,2,4-triazole. Their structures, refined from X-ray powder diffraction, their CO2 adsorption and photoluminescent properties show a direct correlation with the structure o…
The results of optical investigation of hydrogenated epitaxial bilayer graphene are presented. A softening and an increase of the intensity of the in-plane anti-symmetric phonon mode are observed at 0.2eV. It is suggested that they both originate from coupling of the optically active phonon mode to virtual electronic…
The synthesis of the platy form of titanates is challenging owing to their high tendency to form fibrous structures. Here, we report the successful preparation of plate-like potassium titanate starting from layered titanate, K0.8Mg0.4Ti1.6O4, with a lepidocrocite-like structure. Plate-like K2Ti6O13 was first prepared…
Peptides and peptide conjugates elicit considerable interest for diverse applications ranging from materials science to biology, for unique molecular recognition properties, and for solution phase self-assembly. Diketopiperazines (DKPs) are an important class of cyclic scaffolds, which offer a useful platform for stud…
TiO2 mesoporous microspheres self‐assembled from nanoparticles were synthesized by a surfactant‐free solvothermal route. The TiO2 precursors were fabricated by tetrabutyl titanate, glacial acetic acid, and urea in the ethanol solution at 140°C for 20 h, and TiO2 mesoporous microspheres were obtained by a postcalcinati…
Aspirin or acetylsalicylic acid has been utilised by physicians for hundreds of years as an analgesic, anti-inflammatory and antipyretic (1). Derived from plant sources, such as the willow tree, it...
The charge compensation effects induced by aliovalent doping were studied in the monoclinic CdSiO3. An interstitial oxide ion may be feasible in this host to provide the extra negative charge required by the R3+ doping. The oxide was studied in CdSiO3 using density functional theory (DFT) calculations and synchrotron…
