Protein Crystallization Seen in Real Time

A team of investigators from the Molecular Foundry announce that atomic force mciroscopy can now be used to determine how a certain class of proteins promotes the development of crystals in cell-like environments. The work focused on analyzing surface-layer (S-layer) proteins, which are the primary point of contact b...

Nanoparticle Crystallization Seen in Real Time

A collaboration between two institutions at the US Department of Energy's (DOE) Argonne National Laboratory (ANL) recently managed to produce the most detailed images of nanoparticle crystallization taking place in real time. Physicists from the Advanced Photon Source (APS) worked together with colleagues from t...

New Details on How Crystals Form

Crystallization is the name given to the process that sees the transformation of a solution, melt or gas into solid crystals, through precipitation. The phenomenon takes place relatively slow when compared to other types of chemical reactions, and scientists have recently discovered one of the reasons for that. It wo...

Researchers Develop Low-temperature Silicon Crystallization Technique

Silicon conversion from a disordered state to an ordered one can usually be carried out at temperatures as high as 700 degrees Celsius, which disables the possibility of applying silicon substrates on materials such as plastic or paper, due to enhanced heat sensitivity. Max Planck Institute of Metals Research scienti...

Fighting Friction and Stiction for a Smoother Ride

Micro-electro-mechanical systems, popularly referred to as MEMS, in small electronic devices often fail because of adhesion and stiction - the attractive force between the surfaces of interacting parts. University of Arkansas researchers have developed a surface-topography engineering method that reduces these forces...
