As the domestic petrochemical industry pays increasing attention to production safety, enterprises such as Yangzi Petrochemical are also constantly exploring and practicing, striving to adopt more advanced anti-explosion design in building structure design. Roxtec sealing system, with its reliable safety performance, has become the ideal choice for many chemical companies. It can not only withstand the strong impact of the explosion, but also ensure the structural integrity of the building, so that it maintains its original anti-explosion performance.

Science Daily, Beijing, January 31 (Reporter Liu Xia) — American scientists published a paper in the latest issue of Nature magazine, announcing that they have designed two biosensors based on viral proteins.

Professor Chen Yifeng's research group from the School of Chemistry and Molecular Engineering of East China University of Science and Technology and Ferlinga Joint Research Center for Nobel Prize Scientists has made new progress in asymmetric multi-component coupling reactions of alkenes. Relevant research was published online in the Journal of the American Chemical Society.

Recently, Professor Zhang Guoqing's team at the Hefei National Research Center for Microscale Physical Sciences at the University of Science and Technology of China reported the discovery of a new mode of interaction between organic molecules: that is, a stable light-induced charge transfer complex can be formed between aromatic imides and aliphatic amines , and systematically studied the properties and formation process of the complex through steady-state and time-resolved emission spectra, absorption spectra, mass spectrometry, paramagnetic resonance spectroscopy, etc., and proved that the complex can be used for light-induced polymerization and carbon dioxide photoreduction. , UV energy storage and other fields. The result was published in Chem under the title "Trapping Highly Reactive Photo-Induced Charge-Transfer Complex Between Amine and Imide by Light".
