Nature:Chemical and Biological Recycling,and Novel Micro- and Nanodevices

摘要

After perusing this years Nature issues for articles that are related to recycling through chemistry,the Earth Day theme of this JCE issue,we decided to report on two advances:the more efficient generation of hydrogen,a recyclable energy source;and the remarkable way in which certain bacteria recycle the greenhouse gas,methane.In addition,we have included two articles that point the way to ever smaller analytical and mechanical devices of the future.
