Self-assembling protein filaments designed and built from scratch

ScienceDaily.com: Nanotechnology News - Thu, 11/08/2018 - 23:22
For the first time, scientists have created, from scratch, self-assembling protein filaments built from identical protein subunits that snap together spontaneously to form long, helical, thread-like configurations. Protein filaments are essential components of several structural and moving parts in living cells, as well as many body tissues. Being able to design and build protein filaments could allow for engineering novel materials for nano-electronics or scaffolds for new diagnostic tests.

Metallic nanocatalysts imitate the structure of enzymes

NanoWerk.com - Thu, 11/08/2018 - 17:16
An international team of researchers has transferred certain structural characteristics of natural enzymes, which ensure particularly high catalytic activity, to metallic nanoparticles. The desired chemical reaction thus did not take place at the particle surface as usual, but in channels inside the metal particles - and with three times higher catalytic activity.

ScienceDaily.com: Nanotechnology News - Wed, 11/07/2018 - 19:35
A research group has successfully developed a methodology for enhancing thermoelectric power factor while decreasing thermal conductivity. By introducing ZnO nanowires into ZnO films, the thermoelectric power factor became 3 times larger than that of ZnO film without ZnO nanowires. The success of this research will lead to the realization of high-performance transparent thermoelectric devices which will enable energy recovery from transparent objects used all over the world.
