(Phys.org)—Biological systems are characterized by a form of molecular recycling – and proteins do not escape this fate. In particular, unneeded or damaged proteins biochemically marked for destruction undergo controlled ...
As electronic, thermoelectric and computer technologies have been miniaturized to nanometer scale, engineers have faced a challenge studying fundamental properties of the materials involved; in many cases, targets are too ...

Materials scientists typically use solution-phase transmission electron microscopy (TEM) to reveal the unique physiochemical properties of three-dimensional (3-D) structures of nanocrystals. In a new report on Science Advances, ...
Femtosecond lasers can be integrated with electron microscopes to directly image transient structures and morphologies in materials in real time and space. In a new report, Xuewen Fu and a team of scientists in condensed ...
Everyday transitions from one state of matter to another—such as freezing, melting or evaporation—start with a process called "nucleation," in which tiny clusters of atoms or molecules (called "nuclei") begin to coalesce. ...
