In this work we report strategies to nucleate bimetallic nanoparticles (NPs) made by gas phase synthesis of elements showing difficulty in homogeneous nucleation. It is shown that the nucleation assisted problem of bimetallic NP synthesis can be solved via the following pathways: (i) selecting an element which can itself nucleate and act as a nucleation center for the synthesis of bimetallic NP...

We report a simple yet effective approach for the decoration of the TiO2 nanocrystal surface with size-tunable CuO nanodots for high-performance noble metal-free photocatalytic H2 production. Modification with polyacrylic acid enables the surface of TiO2 nanocrystals to be selectively deposited with Cu(OH)2 nanodots, which can be subsequently converted to CuO through dehydration without changin...

background:   h2-eb1 molecule which is the homolog of human hla-drb1 is proposed to be associated with allergic rhinitis (ar). construction of   h2-eb1 knockout animal models provides a tool to elucidate the role of h2-eb1 and ar pathogenesis. objective:   to establish the h2-eb1 knockout model and investigate the h2-eb1 functions in   h2-eb1 knockout mice as a model of ar. methods: the cre/lox...

Matrimid®5218 hollow fiber membranes were prepared using the dry-wet spinning process. The transport properties were measured with pure gases (H2, CO2, N2, CH4 and O2) and with a mixture (30% CO2 and 70% N2) in dry and wet conditions at 25 °C, 50 °C, 60 °C and 75 °C and up to 600 kPa. Interesting values of single gas selectivity up to 60 °C (between 31 and 28 for CO2/N2 and between 33 and 30 fo...

The combination of density-functional theory with other approaches to the many-electron problem through the separation of the electron–electron interaction into a short-range and a long-range contribution (range separation) is a successful strategy, which is raising more and more interest in recent years. We focus here on a range-separated method in which only the short-range correlation energy...

Hydrogen Evolution Reaction In article number 2300961, Dominik Eder and co-workers test a visible light responsive titanium-based metal-organic framework (MOF) comprised of 2D secondary building units for the hydrogen evolution reaction. It ranks amongst highest performing MOFs this challenging conversion. Upon photoexcitation, unique structure enables efficient charge separation extraction, di...

The separation of nanoparticles from a solution-based photocatalytic reaction is significant problem in practical applications. To address the issue, we developed new photocatalyst composite based on ZnO-ZnS heterojunction (ZnOS) embedded polyvinyl alcohol (PVA) hydrogel, which showed satisfactory results for recycling. PVA-ZnOS hydrogel was fabricated by freezing-induced gelation, enabled enca...

In this study, a novel technology for the comprehensive utilization of low-grade iron ore is presented. For with Fe content 24.91%, pilot-scale study pre-concentration, suspension magnetization roasting, grinding, and low-intensity magnetic separation was conducted, an concentrate grade 62.21% recovery 85.72% obtained. The products were analysed using chemical elemental analysis, particle size ...
