Single-walled carbon nanotubes (SWCNTs) are composed entirely of carbon atoms and can be regarded as one-dimensional materials rolled from a single layer of graphene. Single-walled carbon nanotubes can be used as conductive agents in energy storage devices such as high-energy-density lithium batteries, sodium-ion batteries, and solid-state batteries. They can also...

Polysulfamide is a linear polymer with selective metal (palladium) adsorption capacity. The research group of Professor Yi Wenbin of Nanjing University of Science and Technology has developed a general method for preparing polysulfamide using secondary amines, and uses palladium to assist the synthesis of polysulfamide. A palladium-crosslinked polysulfamide skeleton metal...

Azasaccharides are a class of sugar mimetics with important biological and pharmacological activities and play an important role in glycochemistry and glycobiology [1]. Studies have shown that azasugar exhibits excellent glycosidase inhibitory activity, glycosyltransferase inhibitory activity and nucleoside phosphorylase inhibitory activity. Therefore, azasugar has broad application prospects in the treatment...

In August 2018, the team of Academician Shao Feng, deputy director of the Beijing Institute of Life Sciences, published a research paper titled "Alpha-kinase 1 is a cytosolic innate immune receptor for bacterial ADP-heptose" in Nature, proving for the first time that two Adenosine heptose monophosphate (ADP-heptose) can be used...

Benzo[a]pyrene (B[a]p) is a typical polycyclic aromatic hydrocarbon with strong teratogenic, carcinogenic and mutagenic properties. After entering the human body, it undergoes a series of metabolic activation to generate 7,8-diol-9, 10 Epoxy benzopyrene (benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide, BPDE). This metabolite has two pairs of enantiomers: (±)anti-BPDE and (±)syn-BPDE. A large number of studies...

The Ullman reaction was discovered by Ullman in 1903. It usually refers to a copper-catalyzed cross-coupling reaction between an aryl halide and a nucleophile such as oxygen, nitrogen, sulfur, phosphorus or carbon. This reaction not only requires the use of an excess of copper catalyst, but also requires high temperature...
