Analytical Instruments

In July 1978, Peter Buseck of Arizona State University, together with two postdoctoral researchers (also then at ASU), published a paper on a new technique for high-resolution imaging of crystal structures using transmission electron microscopes. Recently, the scientific journal Nature has hailed that paper as a milestone in the science of crystallography. At the same time, Nature also cited three other milestone crystallography papers.

A research group led by Professor Hiroyuki Noji, Department of Applied Chemistry, Graduate School of Engineering, University of Tokyo, successfully observed and touched the rotational motion of a 1-nm synthetic molecular machine through the application of a single-molecule capturing and manipulation technique using optical microscopy and a bead probe (single-molecule motion capturing), which allows visualization of molecular mechanical motion.

Criminals are smuggling an estimated $30 billion in U.S. currency into Mexico each year from the United States, but help could be on the way for border guards, researchers reported recently. The answer to the problem: a portable device that identifies specific vapors given off by U.S. paper money.
