Carnegie Mellon scientists use 'green' approach to transform plastics manufacturing

...cture using a special catalyst to add one or a few monomer units at a time to a growing polymer chain. ATRP requires a balance between two species of copper (Cu) catalyst, CuI and CuII. But as an ATRP reaction progresses, CuII builds up. Typically, researchers add more CuI to compensate for this effect and m...

Recombination protein dynamics observed with single monomer resolution

...filament, which grows and shrinks primarily by one monomer at a time, the researchers report in the August issue of the journal Cell. RecA is a DNA recombination protein found in the gut bacterium E. coli. A human homolog, called Rad51, interacts with many proteins, including BRCA2, whose mutation increases...

Duke Chemists Isolating Individual Molecules Of Toxic Protein In Alzheimer's, Parkinson's Disease

...ycol molecules. They then attach one such tethered monomer to a microscope slide and the other to the AFM microscope tip. They can then bring the isolated and suspended molecules together to study how and whether they interact. The Duke researchers study these interactions by retracting the tip of their AFM...
