Newswise: Researchers Discover Highest-Energy Light From a Gamma-ray Burst

Researchers Discover Highest-Energy Light From a Gamma-ray Burst

George Washington University

An international team of researchers, including two astrophysicists from the George Washington University, has observed a gamma-ray burst with an afterglow that featured the highest energy photons—a trillion times more energetic than visible light—ever detected in a burst.

Hubble Studies Gamma-Ray Burst with the Highest Energy Ever Seen

Space Telescope Science Institute (STScI)

NASA’s Hubble Space Telescope has given astronomers a peek at the location of the most energetic outburst ever seen in the universe—a blast of gamma-rays a trillion times more powerful than visible light. That’s because in a few seconds the gamma-ray burst (GRB) emitted more energy than the Sun will provide over its entire 10-billion year life.

Newswise: 3D-Printed Plastics With High Performance Electrical Circuits

3D-Printed Plastics With High Performance Electrical Circuits

Rutgers University-New Brunswick

Rutgers engineers have embedded high performance electrical circuits inside 3D-printed plastics, which could lead to smaller and versatile drones and better-performing small satellites, biomedical implants and smart structures. They used pulses of high-energy light to fuse tiny silver wires, resulting in circuits that conduct 10 times more electricity than the state of the art, according to a study in the journal Additive Manufacturing. By increasing conductivity 10-fold, the engineers can reduce energy use, extend the life of devices and increase their performance.

Zinc-anode batteries prove their mettle

Cornell University

Researchers working with Lynden Archer, Cornell’s James A. Friend Family Distinguished Professor of Engineering, have found a way to build a zinc-anode battery that not only has a high energy density, but is low cost, robust and stable, and has a life cycle that can be significantly prolonged.

Newswise: New technique lets researchers map strain in next-gen solar cells

New technique lets researchers map strain in next-gen solar cells

University of Washington

Researchers can now map strain in lead halide perovskite solar cells. Their approach shows that misorientation between perovskite crystals is the primary contributor to the buildup of strain within the solar cell, creating defects in grain structure, interrupting electron transport and causing heat loss.

Big Improvements in Thin-film Solar Cell Efficiency Now Possible

Penn State Materials Research Institute

Researchers at Penn State and Delaware have developed a theoretical method to improve the efficiency of thin-film solar cells by up to 33 percent. Flexible thin-film solar cells are needed to supply electrical power to fabrics, clothing, back packs and anywhere that a local autonomous power supply is required.
