Graphene-based actuator swarm enables programmable deformation

NanoWerk.com - Wed, 04/01/2020 - 18:34
Graphene-based actuators featuring fast and reversible deformation under various external stimuli are promising for soft robotics and MEMS. However, these bimorph actuators are incapable of complex and programmable 3D deformation, which limits their practical application. Inspired from the collective coupling and coordination of living cells, researchers proposed a moisture-responsive graphene actuator swarm that has programmable shape-changing capability by patterning the SU-8 inert layer underneath.

On Mars or Earth, biohybrid can turn carbon dioxide into new products

ScienceDaily.com: Nanotechnology News - Tue, 03/31/2020 - 21:00
Chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture organic compounds ranging from fuels to drugs. The efficiency is greater than the photosynthetic efficiency of most plants.

Manipulating noble metal aerogels by reductant chemistry

NanoWerk.com - Mon, 03/30/2020 - 11:05
One of the key issues that is holding back widespread applications of noble metal aerogels is a lack of understanding of the underlying structure-performance correlations. Presumably, this is caused by an insufficient understanding of the sol-gel process that limits manipulating versatile parameters, such as ligament sizes, compositions, and spatial element distributions. Recently published findings not only take a big step towards the detailed understanding of reductant chemistry and gelation mechanisms, manipulating the microstructures, and enriching the compositions of NMAs, but also open a new dimension for devising high-performance electrocatalysts by taking advantage of the ligand effects.
