Relatively inexpensive compound could perform safely and effectively in solar cells. A team of engineers, material scientists, and physicists demonstrated how a new material — a lead-free chalcogenide perovskite — that hadn’t previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered.

A widespread transition to solar energy will depend heavily on reliable, safe, and affordable technology like batteries for energy storage and solar cells for energy conversion. At Rensselaer Polytechnic Institute, researchers are focused heavily on both parts of that equation.

In research published today in Advanced Functional Materials, a team of e...

Phase 1 trial shows promise for completion of stalled eradication effort; offers lessons for COVID-19 vaccine development. Virologists report promising Phase 1 clinical results for the first new oral polio vaccine in 50 years, which they have designed to be incapable of evolving the ability to cause disease in humans.

Before being halted due to the COVID-19 pandemic, a relentless vaccination campaign had nearly succeeded in eradicating polio from the world...

Researchers see application in future quantum technologies. The fundamental laws of physics are based on symmetries that, among other things, determine the interactions between charged particles. Using ultracold atoms, researchers at Heidelberg University have experimentally constructed the symmetries of quantum electrodynamics. They hope to gain new insights for implementing future quantum technologies that can simulate complex physical phenomena. The results of the study were published in the journal Science.

The theory of quantum electrodynamics deals with the electromagnetic interaction between electrons and light particles...
