Durable wood 'sponges' act as green sensors of mechanical strain

ScienceDaily.com: Nanotechnology News - Thu, 03/01/2018 - 21:51
Striking just the right balance between softness and sturdiness, balsa wood is a choice material for crafting anything from model airplanes to full-size wind turbine blades. Scientists have opened up a new realm of possibilities for balsa by hijacking its natural structure with chemical and physical treatments to transform it into a 'wood carbon sponge' capable of enduring repeated compression and other extreme mechanical conditions.

Controlled release of nanohydrogel from halloysite nanotubes

NanoWerk.com - Thu, 03/01/2018 - 04:01
A popular structure for the development of nanodelivery systems are hollow tubular nanoparticles. In new work, researchers show that a hydrogel can be confined within the cavity of halloysite nanotubes (HNTs) by means of an easy strategy. The alginate network inside the HNTs cavity can be triggered by chemical stimuli (by calcium chelators) altering the kinetics, which results in the release of the cargo. This shows that halloysite with tunable hydrophilic/hydrophobic interfaces can act as nanotemplate for the synthesis of drug delivery systems based on biopolymer hydrogels.
