Electrochemical tech used to finely shape 3D-printed metal items

Although it’s certainly possible to 3D-print metal objects, such items can’t always be formed down to the sub-millimeter precision required for certain applications. A new technique, however, allows them to be infinitesimally tweaked after being printe… Continue reading Electrochemical tech used to finely shape 3D-printed metal items→

Surface treatment makes aluminum antiviral and antibacterial

If there’s one place where you don’t want viruses or harmful bacteria to be present, it’s in hospitals, where people are already vulnerable. A new process could help, by allowing aluminum surfaces in such buildings to kill the bugs.Continue ReadingCate… Continue reading Surface treatment makes aluminum antiviral and antibacterial→

Multi-function e-glasses track the brain, eyes and more

We’ve already seen electronic glasses that watch the wearer’s diet and automatically change focus, among other things. An experimental new pair monitors the user’s health, lets them control games, and switch to being sunglasses as needed.Continue Readi… Continue reading Multi-function e-glasses track the brain, eyes and more→

Synthetic version of natural antifreeze used in longer-lasting concrete

As readers who live in cold climates will likely already know, winter is not kind to concrete. That could be about to change, though, thanks to a polymer additive that mimics natural antifreeze.Continue ReadingCategory: Materials, ScienceTags: Universi… Continue reading Synthetic version of natural antifreeze used in longer-lasting concrete→
