The aza-Michael reaction as an alternative strategy to generate advanced silicon-based (macro)molecules and materials

Here, we show that this addition reaction is efficient for modifying or curing silicon-containing molecules, oligomers and polymers. The pros and cons of applying the aza-Michael reaction to silicon-containing molecules (including alkoxysilanes and PDMS) are highlighted.

Polymer-Supported Chiral-at-Metal Lewis Acid Catalysts

The covalent immobilization of a chiral-at-metal bis-cyclometalated iridium(III) catalyst on a solid support is reported, and its catalytic activity has been investigated.

Bioinspired process makes materials light, robust, programmable at nano- to macro-scale

MEDFORD/SOMERVILLE, Mass. - Researchers at Tufts University's School of Engineering have developed a new bioinspired technique that transforms silk protein into complex materials that are easily programmable at the nano-, micro- and macro-scales as well as ultralight and robust. Among the varied structures generated was a web of silk nano fibers able to withstand a load 4,000 times its own weight. (http://dx.doi.org/10.1038/nnano.2017.4) (press release)

How protein misfolding may kickstart chemical evolution

Alzheimer's disease, and other neurodegenerative conditions involving abnormal folding of proteins, may help explain the emergence of life - and how to create it. (press release)
