Robert Ritchie Comments on Manufacturing of Apple’s iPhone Sapphire Screens

Materials scientist is quoted in MIT Technology Review on Apple’s latest product — a sapphire screen that is supposed to be much stronger than the glass currently used. To prevent a gadget’s screen from cracking, defects that might allow scratches must be avoided, and the design needs to absorb energy of impact, he says. More>

A Metallic Alloy That is Tough and Ductile at Cryogenic Temperatures

A multi-element high‐entropy alloy not only tests out as one of the toughest materials on record, but, unlike most materials, the toughness as well as the strength and ductility of this alloy actually improves at cryogenic temperatures. More>

Lab Licenses Boron Nitride Nanotube Technology

Nearly 20 years ago Alex Zettl synthesized this never-seen-before material, the strongest, lightest, most thermally conducting, and most chemically resistant fiber known to exist. Now a startup has licensed this technology with the aim of manufacturing boron nitride nanotubes for commercial use. More>

Bottling Up Sound Waves

Materials scientists have developed a technique for generating acoustic bottles in open air that can bend the paths of sound waves along prescribed convex trajectories. These self-bending bottle beams hold promise for ultrasonic imaging and therapy, acoustic cloaking, and levitation and particle manipulation. More>
