Multi-material Additive Manufacturing of Metamaterials with Giant, Tailorable Negative Poisson's Ratios
(Springer Nature, 2018-06-14)
Nature has evolved with a recurring strategy to achieve unusual mechanical properties through coupling variable elastic moduli from a few GPa to below KPa within a single tissue. The ability to produce multi-material, ...
Harvesting Energy from the Counterbalancing (Weaving) Movement in Bicycle Riding
Bicycles are known to be rich source of kinetic energy, some of which is available for harvesting during speedy and balanced maneuvers by the user. A conventional dynamo attached to the rim can generate a large amount of ...

The regulatory environment changed January 1, 2017 for producers who wish to continue to use certain antibiotics in feed & water for animals. - Education is key to understanding the rules and how to maintain compliance. - ...
Waste not want not: life cycle implications of gold recovery and recycling from nanowaste
(Royal Society of Chemistry, 2016-08-24)
Commercial-scale applications of nanotechnology are rapidly increasing. Enhanced production of nanomaterials and nano-enabled products and their resultant disposal lead to concomitant increases in the volume of nanomaterial ...
Stretchable sensors for environmental monitoring
The development of flexible and stretchable sensors has been receiving increasing attention in recent years. In particular, stretchable, skin-like, wearable sensors are desirable for a variety of potential applications ...
Oxone®-Mediated TEMPO-Oxidized Cellulose Nanomaterials form I and form II
The 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO) oxidation of cellulose, when mediated with Oxone<sup>®</sup> (KHSO<sub>5</sub>), can be performed simply and under mild conditions. Furthermore, the products of the ...
Olefin cross-metathesis, a mild, modular approach to functionalized cellulose esters
(The Royal Society of Chemistry, 2014-09-02)
Olefin cross-metathesis has been demonstrated to be a modular pathway for synthesis of a series of functionalized cellulose esters. As a proof of concept, cellulose acetate was acylated with two terminally olefinic acid ...
