When proteins shake hands

ScienceDaily.com: Nanotechnology News - 20 февраля, 2018 - 18:24
Protein nanofibers often have outstanding properties such as a high stability, biodegradability, or antibacterial effect. Artificially creating these fibers is not easy, much less assigning them specific functions. That and how fibers with new properties can be successfully created is now being reported by materials scientists in a new study.

Creating highly tunable adhesives with Kirigami-inspired structures

Nanowerk.com - 19 февраля, 2018 - 10:16
Tuning adhesion without relying on chemical treatment or micro or nanostructured surfaces is now closer with a novel, kirigami-inspired approach. New research shows that by carefully designing arrays of cuts in an adhesive film, the stickiness can not only be tuned by a factor of 100 across a single sheet, but also be decreased for an easy-release purpose. These kirigami-inspired structures at interfaces provide a mechanism to spatially control and enhance adhesion strength while providing directional characteristics for high-capacity, easy-release interfaces.
