MIT uncovers hidden atomic patterns in metals
Imeripotiwa na AI
Researchers at MIT have discovered that metals retain subtle atomic patterns even after standard manufacturing processes, challenging long-held assumptions. These patterns, driven by microscopic dislocations, could enable engineers to customize material properties for demanding applications. The finding, published in Nature Communications, reveals a new physical principle in metallurgy.
Munro teardown reveals differing EV motor cooling approaches by Tesla and GM
Imeripotiwa na AI
Engineering firm Munro & Associates has dissected electric motors from the Tesla Cybertruck and Chevrolet Equinox, uncovering stark contrasts in their cooling strategies. General Motors opts for a simple, physics-based method, while Tesla employs precise, pump-driven cooling. These differences highlight trade-offs between simplicity and efficiency in electric vehicle powertrains.
Physicists uncover rotating crystals with lifelike properties
A team of physicists has discovered unusual rotating crystals made of spinning particles that exhibit behaviors resembling living matter, such as twisting instead of stretching and self-reassembly after breaking. These materials, governed by transverse interactions, challenge conventional crystal growth rules. The findings, published in the Proceedings of the National Academy of Sciences, suggest potential applications in technology and biology.
