Converting Small Amounts of Freely Available Energy into Electricity

There are many forms of energy around us: light, heat, vibrations, wind, electromagnetic fields, fluid flow, waves, organic waste, etc. At large scale, many of these energy sources already play a significant role in powering our society and are projected to become dominant contributors by 2040. On the smaller scale, exciting scientific and engineering challenges must be overcome to harness these energy sources.

In-place manufacturing method improves gas sensor capabilities, production time

Gas sensor capabilitites

By Mariah R. Lucas

When used as wearable medical devices, stretchy, flexible gas sensors can identify health conditions or issues by detecting oxygen or carbon dioxide levels in the breath or sweat. They also are useful for monitoring air quality in indoor or outdoor environments by detecting gas, biomolecules and chemicals. But manufacturing the devices, which are created using nanomaterials, can be a challenge. 

Researchers uncover mechanisms to easily dry, redisperse cellulose nanocrystals

UNIVERSITY PARK, Pa. — Cellulose nanocrystals — bio-based nanomaterials derived from natural resources such as plant cellulose — are valuable for their use in water treatment, packaging, tissue engineering, electronics, antibacterial coatings and much more. Though the materials provide a sustainable alternative to non-bio-based materials, transporting them in liquid taxes industrial infrastructures and leads to environmental impacts.

Unconventional experiments produce new nanoscale particles with big potential

By Sam Sholtis

Nanoparticles are complex materials smaller than 100 nanometers, or about the size of a virus, but they have a large range of potential applications, from medicine to energy to electronics. Now, hundreds of new nanoparticles with previously unknown features have been produced using an innovative experimental approach.
