Spin Effect to Promote Reaction Kinetics and Overall Performance of Lithium-Sulfur Batteries under External Magnetic Field.

Lithium-sulfur batteries (LSBs) are still limited by the shuttle of lithium polysulfides (LiPS) and the slow Li-S reaction. Herein, we demonstrate that when using cobalt sulfide as a catalytic additive, an external magnetic field generated by a permanent magnet can significantly improve the LiPS adsorption ability and the Li-S reaction kinetics. More specifically, the results show both experimentally and theoretically how an electron spin polarization of Co ions reduces electron repulsion and enhances the degree of orbital hybridization, thus resulting in LSBs with unprecedented performance and stability.

[PM Pollution Characterization and Cause Analysis of a Winter Heavy Pollution Event, Liaocheng City].

Heavy pollution events frequently occur during fall and winter seasons in northern areas. In order to understand the characteristics and chemical composition of PM during heavy pollution in winter in Liaocheng City, ambient PM samples were collected between January 7-11,2016. Mass concentration, water-soluble ions, carbonaceous species, and elements were analyzed, as well as the causes of pollution.

Enhanced expression and phosphorylation of the MET oncoprotein by glioma-specific PTPRZ1-MET fusions.

PTPRZ1-MET (ZM) proteins are a group of fusion proteins identified in human gliomas by high-throughput transcriptome sequencing. ZM fusions are associated with poor prognosis in afflicted glioma patients and mediate oncogenic effects in assays. In this study, we show that ZM-carrying patients have increased hepatocyte growth factor receptor (MET) mRNA expression levels induced by fusion with receptor-type tyrosine-protein phosphatase zeta (PTPRZ1).

2-[4-(Chloro-meth-yl)phen-oxy]-4,6-dimeth-oxy-pyrimidine.

The title compound, C(13)H(13)ClN(2)O(3), was synthesized in the course of the search for novel bioactive pyrimidine derivatives. The C-O-C angle at the phen-oxy O atom is widened to 119.87 (18)°.

Vacuum electron acceleration driven by two crossed Airy beams.

Using numerical simulation, we have studied in detail vacuum electron acceleration driven by two crossed Airy beams with identical characteristics except for opposite accelerating directions. An electron injected along the longitudinal central axis is only affected by the combined longitudinal electric field. In addition, a suitable crossed Airy beams scheme is more beneficial to the energy gain of an electron than the single Airy beam acceleration scheme [Opt.

Adenoviruses use lactoferrin as a bridge for CAR-independent binding to and infection of epithelial cells.

Most adenoviruses bind to the coxsackie- and adenovirus receptor (CAR). Surprisingly, CAR is not expressed apically on polarized cells and is thus not easily available to viruses. Consequently, alternative mechanisms for entry of coxsackievirus and adenovirus into cells have been suggested.
