Fragmented Polymetric Carbon Nitride with Rich Defects for Boosting Electrochemical Synthesis of Hydrogen Peroxide in Alkaline and Neutral Media.

Electrocatalytic oxygen reduction reaction via 2e pathway is a safe and friendly route for hydrogen peroxide (HO) synthesis. In order to achieve efficient synthesis of HO, it is essential to accurately control the active sites. Here, fragmented polymetric carbon nitride with rich defects (DCN) is designed for HO electrosynthesis.

Effects of poplar addition on tar formation during the co-pyrolysis of fat coal and poplar at high temperature.

Three-stage absorption by butyl acetate was used to obtain tar components during the co-pyrolysis of fat coal and poplar at high temperature. The resulting tar yields were calculated relative to the fat coal and poplar blends. The tar components were characterized by gas chromatography-mass spectrometry, Fourier transform-infrared spectroscopy and H nuclear magnetic resonance spectroscopy.

Role of generation on folic acid-modified poly(amidoamine) dendrimers for targeted delivery of baicalin to cancer cells.

Baicalin (BAI) has been reported to exert antitumor effects. However, BAI has limited water solubility, non-specific tumor targeting, and low bioavailability, which severely limited its clinical application. The aim of this study was to develop folic acid (FA) covalently conjugated-polyamidoamine (PAMAM) dendrimers (PAMAM-FA) as carrier systems for improvement of water solubility and tumor-specificity of BAI, and study the role of generation on the physiochemical properties and biological effects of PAMAM-FA/BAI complexes.
