Single-walled carbon nanotubes are readily observable in a scanning electron microscope, which traditional models fail to explain. We present an ab initio model to explain how the electron beam can interact with these structures despite the ...
现代催化研究方法高级讲习班由从事催化工作50余年，担任催化协会秘书长15余年的辛勤教授发起，以研究生、高等院校青年教师、企业和科研院所相关技术人员为主要对象，着重讲解当前催化研究涉及的主要现代物理方法基本原理、应用实例和存在的问题。近几年来，先后在中国科学院大连化学物理研究所（2007）、浙江师范大学（2...
