Engineering both intrinsic characteristic and local microenvironment of platinum sites toward highly efficient oxygen reduction reaction.

The optimization of the adsorption of oxygen-containing intermediates on platinum (Pt) sites of Pt-based electrocatalysts is crucial for the oxygen reduction reaction process. Currently, a large amount of researches mainly focus on modifying the bulk structure of the electrocatalysts, however, the vital role of solvent effect on the phase interfaces is often overlooked. Here, we successfully developed an electrocatalyst in which the ordered PtCo alloy anchors on the cobalt (Co) single-atoms/clusters decorated support (CoNC) and its surface is further optimized using hydrophobic ionic liquid (IL).

Influence of acetate-to-butyrate ratio on carbon chain elongation in anaerobic fermentation.

This study investigated the effect of electron acceptor (EA) distribution (acetate to butyrate ratio) on the carbon chain elongation (CCE) process. The results showed that the higher content of butyrate in the initial material led to the higher production of caproate. The maximum production of caproate was 3.

Inactivation of , and Bacteriophages in Biofilms by Humidified Air Plasma.

In this study, humidified air dielectric barrier discharge (DBD) plasma was used to inactivate (), (), and bacteriophages in biofilms containing DNA, NaCl, carbohydrates, and proteins. The humidified DBD plasma was very effective in the inactivation of microbes in the (≤1.0 μm) biofilms.

Characterization of lithium zinc titanate doped with metal ions as anode materials for lithium ion batteries.

With the aim of improving the ionic and electronic conductivities of LiZnTiO for high performance lithium ion battery applications, LiZnMTiO (M = Li, Cu, Al, Ti, Nb, Mo) compounds are successfully fabricated using facile high temperature calcination at 800 °C. Physical characterization and lithium ion reversible storage demonstrate that Zn-site substitution by multivalent metal ions is beneficial for improving the migration rate of ions and electrons of LiZnTiO. X-ray diffraction analysis and scanning electron microscopy reveal that the crystal structure and microscopic morphology of bare LiZnTiO do not change by introducing a small amount of foreign metal ions.
