functionalization of multiwalled carbon nanotubes (mwcnts) with nh2 groups under a one pot reaction is studied. during the first step of the reaction, cl and chcl2 groups were attached to the surfaces of mwcnts through an electrophilic addition reaction. in the second step of process, cl atoms were replaced with nh2 and amino groups (ethylene diamine and butyl amine) under a nucleophilic substi...
ABSTRACT Introduction: In the current Chinese basketball team, many players have a high level of training. However, in official competitions, athletes tend to heart rate problems. Therefore, it is importment monitor and control improve their performance. Objective: To explore intermittent endurance Methods: The researchers selected 28 male from university as research objects. Athletes performed...
An eco-friendly synthesis of highly functionalized epoxides and their incorporation into an organocatalytic multicomponent approach are reported. For this, a modified class of diarylprolinol silyl ethers was designed to enable high catalytic activity in an environmentally benign solvent system. The one-pot procedure showed great efficiency in promoting stereoselective multicomponent transformat...
