In the present work, the influence of the photovoltaic effect of the corrosion products of γ-FeOOH and γ-Fe 2 O 3 on the corrosion of Q235 carbon steel (CS) under visible light was qualitatively and quantitatively studied. The photo-voltages and photoinduced current density were simultaneously measured. The photoinduc…
This paper briefly describes the many different sets of ionic and covalent radii available. A simple model of ionic and covalent bonding is proposed and an equation to calculate internuclear distances of covalent, ionic and metallic lattices is described. Derivation of covalent radii and the use of a proposed model of…
ABSTRACT An 2‐ureido‐4[1H]pyrimidinone (UPy) motif with self‐association capability (through quadruple hydrogen bonds) was successfully anchored onto montmorillonite clay layers. Polymer/clay nanocomposites were prepared by specific hydrogen bonding interactions between surface functionalized silica nanoclays and UPy‐…
Enzyme function prediction remains an important open problem. Though structure-based modeling, such as metabolite docking, can identify substrates of some enzymes, it is ill-suited to reactions that progress through a covalent intermediate. Here we investigated the ability of covalent docking to identify substrates th…
The results of a study on the suitability of materials derived from cobalt ferrite for sensor and actuator applications are presented. The mechanism responsible for the superior sensor properties of Ge-substituted cobalt ferrite compared with Ti and other cation substituted cobalt ferrite materials is believed to be d…
The enhanced photoelectrochemical cathodic protection performance of the In 2 O 3 /TiO 2 composite for 304 stainless steel (SS) was investigated in this work. The heterojunction structure of the In 2 O 3 /TiO 2 composite promotes the generation and transfer of the photoinduced electrons, resulting in a larger number o…
5,6-Bis(benzylideneamino)-2-mercaptopyrimidin-4-ol (SCR7) is a new anti cancer molecule having capability to selectively inhibit non-homologous end joining (NHEJ), one of the DNA double strand break (DSB) repair pathways inside the cells. In spite of the promising potential as an anticancer agent, hydrophobicity of SC…
We determined a reliable Au( <sc>i</sc> ) chloride X-ray absorption spectrum from dichlorobenzene solutions containing varying amounts of [AuCl <sub>2</sub> ] <sup>−</sup> and [AuCl <sub>3</sub> OH] <sup>−</sup> .
We present numerical modelling of a dual-band double-negative chirped metamaterial (MM) in the optical region. The MM has an elliptical nanohole array (ENA) penetrating through a metal/dielectric material/metal (Au-Al2O3-Au) film. We consider the case when the chirp is introduced by displacing the positions of the ENA…
Abstract CdSe/CdS core-shell nanocrystals with controlled CdS shell thickness and CdSe core size were synthesized for several different values of these two parameters. The particles in aqueous dispersion were in situ decorated with Ni nanoparticles and evaluated for photocatalytic hydrogen generation capacity. The hig…
A synthetic strategy toward the intriguing hydrocarbon nanorod polytwistane is outlined. Our approach aims toward the polymerization of acetylene starting from precursors that would provide a helical bias for the formation of polytwistane. Both transition-metal-catalyzed and radical polymerizations were investigated.…
We report a successful synthesis of Mesoporous Boron Nitride (MBN) powder through a facile one-pot synthesis strategy.
The corrosion behavior of magnesium-aluminum (Mg-Al) alloy AM50 produced by a rheocasting (RC) technique was examined in the presence and absence of CO 2 at three temperatures −4, 4 and 22°C. The slurry preparation in the RC material was performed with the newly developed RheoMetal process. For reference, 99.97% Mg wa…
B4C and graphite(C) mixed powders were clad by laser at the surface of Ti–6Al–4V alloy in N2 environment. X-ray diffraction (XRD), scanning electron microscope (SEM), and X-ray energy dispersive spectroscopy (EDS) were used to analyze the composite coatings. It was found that TiC, TiB, TiN, and TiB2 which were compris…
This paper shows that pair-distribution function (PDF) analyses can be carried out on organic and organometallic compounds from powder electron diffraction data. Different experimental setups are demonstrated, including selected area electron diffraction and nanodiffraction in transmission electron microscopy or nanod…
PURPOSE: The aim of this study was to develop a technique for rapid collection of chemical exchange saturation transfer images with the saturation varied to modulate signal loss transfer and enhance contrast. METHODS: Multi-echo Length and Offset VARied Saturation (MeLOVARS) divides the saturation pulse of length Tsat…
Gasochromic VO2 thin films were fabricated by the sol-gel spin-coating technique. The results of X-ray absorption spectroscopy and resonant inelastic X-ray scattering spectroscopy reveal that the origin of gasochromic coloration in VO2 is strongly related to the modulation of its structure and the electron-electron co…
A multi-branch thermoviscoelastic-themoviscoplastic finite deformation constitutive model incorporated with structural and stress relaxation is developed for a thermally activated shape memory polymer (SMP) based syntactic foam. In this paper, the total mechanical deformation of the foam is divided into the components…
Here we report the organic-free mesocrystalline superstructured cages of BaTiO3, i.e., the BaTiO3 supercages, which are synthesized by a one-step templateless and additive-free route using molten hydrated salt as the reaction medium. An unusual three-dimensional oriented aggregation of primary BaTiO3 nanoparticles in…
Renewable thermoset elastomers were prepared using the plant-based monomer carvomenthide. Controlled ring-opening transesterification polymerization of carvomenthide using diethylene glycol as an initiator gave α,ω-dihydroxyl poly(carvomenthide) (HO-PCM-OH), which was subsequently converted to carboxy-telechelic poly(…
