Video: Decommissioned wind turbine blades get a second wind through reuse and recycling

By Lisa McDonald / January 20, 2021

The vast majority of wind turbine blades that reach end-of-use are either being stored in various places or taken to landfills because there are few options for recycling. Numerous companies and universities are working to change that.

Achieve success by inversing expectations—scientists show promise of antiperovskite oxides in photovoltaic applications

By Lisa McDonald / January 12, 2021

Perovskite materials are some of the most hotly researched materials in the photovoltaic field right now. However, antiperovskite materials, which have an inverse perovskite structure, show promise as well. Two researchers in Korea used simulations to explore the potential of two antiperovskite oxides in photovoltaic applications.

Addressing the energy harvesting storage gap—ceramic matrix composites contain corrosive materials in thermal energy storage

By Jonathon Foreman / October 2, 2020

Thermal energy storage technologies are one way to store energy generated from renewable sources. But producing materials that can contain the high-temperature and corrosive materials integral to this technology is an ongoing area of research. Two recent ACerS journal articles explore methods of fabricating C/C-SiC CMCs for use as container materials.

Designing Li-S battery cathodes: Polarity rather than conductivity leads to long-term cycling stability

By Lisa McDonald / September 29, 2020

Highly conductive carbon materials are frequently investigated as host materials for sulfur in lithium-sulfur batteries, but such cathodes struggle with loss of sulfur due to the carbon surface being nonpolar. An international team of researchers explored if using polar silica instead as the host material may improve cycling stability, even though silica is nonconductive.
