The synthesis of RGO/Pt–Ni nanocatalysts and the catalytic reduction of p -nitrophenol using the as-synthesized nanocatalysts (magnetic separation and recycling).
(O)(TMC)(X)] complexes (TMC = tetramethylcyclam) and thus appears to be inconsistent with the Two-State Reactivity rationale that is the prevailing explanation for the relative facility of oxoiron(IV) complexes to undergo HAT.
In bulk non-centrosymmetric magnets the chiral Dzyaloshinskii-Moriya exchange stabilizes tubular skyrmions with a reversed magnetization in their centers. While the double-twist is favorable in the center of a skyrmion, it gives rise to an excess of the energy density at the outskirt. Therefore, magnetic anisotropies…
Pt/TiO 2 nanoparticles were prepared by a solvothermal method and used for high efficiency photocatalytic CO 2 conversion.
Homochiral MOFs were engineered using postsynthetic modification and a one-pot synthetic strategy. l -Proline functionalized IRMOF-3 show high ee for aldol reaction. Gold functionalized CUP-1 catalysts are highly efficient for the A 3 coupling reaction.
The radioactivity concentrations of 226 Ra, 232 Th and 40 K in some commercial flooring materials used in Tiruvannamalai, Tamilnadu, India, were measured using NaI(Tl) gamma ray spectrometer. The natural radionuclide contents, Ra equivalent activities and various hazard indices were also calculated to assess the radia…
An operationally simple and environmentally benign formal hydrogenation protocol has been developed using highly abundant iron(iii) salts and an inexpensive, bench stable, stoichiometric reductant, NaBH4, in ethanol, under ambient conditions. This reaction has been applied to the reduction of terminal alkenes (22 exam…
Three-dimensional hybrid nanomaterial of graphene-multiwalled carbon nanotubes (G-MWCNTs) was synthesized using gamma rays emitted by a60Co source with a dose rate of 3.95 Gy min−1. The products were characterized by fourier transform infrared (FTIR), ultraviolet-visible (UV-Vis), photoluminescence (PL), and micro-Ram…
Organic-inorganic hybrid of cobalt phosphonate hollow nanostructured spheres were prepared in a water-ethanol system through a mild hydrothermal process in the absence of any templates using diethylenetriamine penta(methylene phosphonic acid) as bridging molecule. SEM, TEM and N2 sorption characterization confirmed a…
In order to investigate thermochemical energy storage in larger scale, a test bench as well as a reactor containing around 20 kg of reaction material has been built and brought into operation. This investigation is based on the reversible decomposition reaction of calcium hydroxide, due to its wide availability, high…
As a new reduction-sensitive linkage, diselenide bonds can also timely release DNA inside the tumor cells, while remaining constant outside the cells, implying its higher stability during the circulation process and great potential for in vivo gene delivery system design.
Graphene oxide (GOs) has emerged in recent years as a versatile nanomaterial, demonstrating tremendous potential for multifunctional biomedical applications. GOs can be prepared by the top-down or bottom-up approach, which leads to a great variability of GOs being produced due to the different procedures and starting…
For high rate capability and energy density of lithium ion batteries, over-lithiated layered cathodes coated by multiwall carbon nanotube were prepared by a novel dry method without decay in the structure.
Dual-phase TiO2 photocatalysts with controllable ratio of anatase to rutile were synthesized, and evaluated using the degradation of Rhodamine B (RhB) under UV light irradiation. The TiO2 samples prepared by one-pot redox reactions in the presence of graphene oxide (GO) were characterized by X-ray diffraction, physica…
PURPOSE: Dental implant has gained clinical success over last decade with the major drawback related to osseointegration as properties of metal (Titanium) are different from human bone. Currently implant procedures include endosseous type of dental implants with nanoscale surface characteristics. The objective of this…
We explore the possibility for translationally invariant quantum many-body systems to undergo a dynamical glass transition, at which ergodicity and translational invariance break down spontaneously, driven entirely by quantum effects. In contrast to analogous classical systems, where the existence of such an ideal gla…
A bifunctional heterogeneous catalyst based on sulfonated cation exchange resin and embedded Ru nanoparticles shows complete conversion and selectivity at low temperatures and H2 pressure in the direct, one-pot conversion of levulinic acid to GVL under continuous flow conditions, with excellent durability and no need…
During the production of titanium stabilized stainless steel, as titanium in steel has a tendency to reacting with SiO2 in mould fluxes to generate TiO2 into mould fluxes and mould powder can inevitably pick up Ti-bearing inclusions floating up from steel, TiO2 content in the molten mould fluxes gradually increases so…
Helicobacter pylori (H. pylori) successfully colonizes the human stomach of the majority of the human population. This infection always causes chronic gastritis, but may evolve to serious outcomes, such as peptic ulcer, gastric carcinoma or mucosa-associated lymphoid tissue lymphoma. H. pylori first line therapy recom…
Ultrafine grained steels with grain sizes below about 1 m offer the prospect of high strength and high toughness with traditional steel compositions. These materials are currently the subject of extensive research efforts worldwide. Alloy design is one of the first considered issues, while designing new steel with tar…
