Happy Thanksgiving from ASME! We're grateful for our hardworking staff, members, and volunteers worldwide.

With the help of microgravity, researchers at the University of Notre Dame, are developing an extremely sensitive biosensor. https://lnkd.in/eMcJBfxR

Researchers at the Massachusetts Institute of Technology (MIT) in Cambridge have demonstrated that when metal is struck by minuscule objects moving at high velocities, heating the metal makes it stronger. In fact, when subjected to higher temperatures, copper can actually be just as strong as steel.? ? This discovery could lead to exciting new ways to engineer metallic materials for extreme environments, such as shields that protect spacecraft or hypersonic aircraft or equipment for high-speed/high temperature manufacturing processes. https://lnkd.in/gbA4RxgN

Researchers at North Carolina State University have developed a process that speeds up the additive manufacturing of metal machine parts by 33 percent. https://lnkd.in/eJicSh5M

When it comes to closing the gender gap in engineering, not all disciplines are equal. https://lnkd.in/euP7-kUA

The promise of thermophotovoltaic (TPV) cells is that they could scavenge waste heat radiated from exhaust pipes or stored over long periods in hot solid material. As part of a heat battery, these cells could be connected to the grid to store intermittent renewable energy during peak production hours. ? A recent breakthrough has improved the efficiency of these cells considerably, to the point where they are closing in on their theoretical limit. According to researchers, an array of these high-efficiency TPV cells about the size of a living room could produce 1 MW of electricity. https://lnkd.in/eyZP6ctZ

The hope is that a tool developed by researchers may provide the ability for rapid design and testing cycles for oxidation-resistant complex metal alloys. https://lnkd.in/ekWnKScz

Passing the Principles and Practice of Engineering exam is an important achievement—lending professional credibility, bumping up salaries, yielding more responsibility, and offering access to higher-level engineering jobs. But there’s a more practical piece to adding a P.E. after your name. https://lnkd.in/eKSfj4W7

Although they are a much earlier stage material compared to silicon, perovskites' efficiencies are improving and their commercial use in solar cells could be rapidly approaching. https://lnkd.in/eZtshgRQ
