Making a transparent flexible material of silk and nanotubes

ScienceDaily.com: Nanotechnology News - Tue, 10/30/2018 - 20:19
The silk fibers produced by Bombyx mori, the domestic silkworm, has been prized for millennia as a strong yet lightweight and luxurious material. Although synthetic polymers like nylon and polyester are less costly, they do not compare to silk's natural qualities and mechanical properties. And according to new research, silk combined with carbon nanotubes may lead to a new generation of biomedical devices and so-called transient, biodegradable electronics.

High-loading graphene composites meet electronic industry's metrics for thermal conductivity enhancement

NanoWerk.com - Tue, 10/30/2018 - 12:08
Researchers investigated the thermal conductivity and thermal diffusivity of epoxy composites with high loading fractions of graphene and h-BN fillers. They found that the graphene fillers outperformed boron nitride fillers in terms of thermal conductivity enhancement. The surprising finding is that, in the high loading composites with quasi-2D fillers, the apparent cross-plane thermal conductivity of the fillers can be the limiting factor for heat conduction. These results are important for developing the next generation of the thermal interface materials.

Testing nanomedicine in space

NanoWerk.com - Mon, 10/29/2018 - 19:42
Researchers investigated the potentially protective role of nanoceria against oxidative stress associated with microgravity and cosmic radiations in space. Their findings support the application of antioxidant nanomaterials to skeletal muscle tissue culture for protection from the noxious effects of microgravity and cosmic radiations, which result in muscle mass and force loss and limit human operations and permanence in space. On Earth, these deteriorations are usually associated with aging or pathologies and are exhibited over longer time intervals compared to those occurring in space.
