Killer flies can reach accelerations of over 3g when aerial diving to catch their prey - but at such high speeds they often miss because they can t correct their course.
Researchers show in a new study that a single material, a layered crystal consisting of the elements rhenium and silicon, turns out to be the gold standard of transverse thermoelectric devices.

A new spray-on ceramic which claims to be harder than sand and provides more coverage for stealth airplanes and bombers have been created. Compared to the older coating, it has more improvements, reported the Daily Mail.
Stealth jets coating is better than ever
The North Carolina University made the material to resolve the limits of normal polymer skins that tear off aircraft skin and expose the aircraft to enemy radar scans.
Rice Lab Uses Laser-Induced Graphene Process to Create Micron-Scale Patterns in Photoresist
A Rice University laboratory has adapted its laser-induced graphene technique to make high-resolution, micron-scale patterns of the conductive material for consumer electronics and other applications.
Laser-induced graphene (LIG), introduced in 2014 by Rice chemist James Tour, involves burning away everything that isn’t carbon from polymers or other materials, leaving the carbon atoms to reconfigure themselves into films of characteristic hexagonal graphene.
The process employs a commercial laser that “writes” graphene patterns into surfaces that to date have included wood, paper and even food.
The new iteration writes fine patterns of graphene into photoresist polymers, light-sensitive materials used in photolithography and photoengraving. Baking the film increases its carbon content, and subsequent lasing solidif
AUSTIN, Texas - A universally applicable digital twin mathematical model has been co-developed by researchers at The University of Texas at Austin that.
