Metal- and light-free approach to polyheterocycles via a quinone-Cs2CO3 couple promoted regioselective cascade radical cyclization

open access: yesGreen Synthesis and Catalysis
A highly efficient, transition-metal- and light-free approach to polyheterocycles via regioselective cascade radical cyclization is developed. The redox-neutral protocol has a broad substrate scope with good functional group tolerance and probably ...

Design and verification of a bamboo-like structure pipeline based on SLA-3D printing [PDF]

open access: yesAIP Advances
This study focuses on structural biomimetics, using bamboo as the biomimetic object. Owing to the porous and lightweight characteristics of bamboo, its macroscopic structure was simplified and simulated to design a pipeline. The changes in pore structure
