Photocatalytic Air Purification Using Functional Polymeric Carbon Nitrides.

The techniques for the production of the environment have received attention because of the increasing air pollution, which results in a negative impact on the living environment of mankind. Over the decades, burgeoning interest in polymeric carbon nitride (PCN) based photocatalysts for heterogeneous catalysis of air pollutants has been witnessed, which is improved by harvesting visible light, layered/defective structures, functional groups, suitable/adjustable band positions, and existing Lewis basic sites. PCN-based photocatalytic air purification can reduce the negative impacts of the emission of air pollutants and convert the undesirable and harmful materials into value-added or nontoxic, or low-toxic chemicals.

Metalated carbon nitrides as base catalysts for efficient catalytic hydrolysis of carbonyl sulfide.

A new type of base catalyst was designed and prepared by metalation of carbon nitrides with alkali metal ions. The as-prepared metalated carbon nitride composites showed enhanced basicity and efficient catalytic hydrolysis of carbonyl sulfide. The results of this study demonstrate that the metalation of carbon nitrides holds great promise for base catalysis applications.

Discovery of Four Novel Viruses Associated with Flower Yellowing Disease of Green Sichuan Pepper () by Virome Analysis.

An emerging virus-like flower yellowing disease (FYD) of green Sichuan pepper ( v. ) has been recently reported. Four new RNA viruses were discovered in the FYD-affected plant by the virome analysis using high-throughput sequencing of transcriptome and small RNAs.

Fabrication and characterization of back-side illuminated InGaN/GaN solar cells with periodic via-holes etching and Bragg mirror processes.

In this study, the design and fabrication schemes of back-side illuminated InGaN/GaN solar cells with periodic via-holes etching and Bragg mirror processes are presented. Compared to typical front-side illuminated solar cells, the improvements of open-circuit voltage (V(oc)) from 1.88 to 1.

Maternal phylogeny of a newly-found yak population in china.

The Jinchuan yak is a new yak population identified in Sichuan, China. This population has a special anatomical characteristic: an additional pair of ribs compared with other yak breeds. The genetic structure of this population is unknown.

N-[(6-Bromo-2-meth-oxy-3-quinol-yl)phenyl-meth-yl]-2-morpholino-N-(1-phenyl-ethyl)acetamide.

In the title compound, C(31)H(32)BrN(3)O(3), the morpholine ring adopts a chair conformation, and the planar quinoline system is twisted with respect to the phenyl rings, with dihedral angles of 17.6 (4) and 75.1 (3)°.
