Skin-inspired coating that’s as hard as teeth and can heal itself

Self-healing smart coatings could someday make scratches on cell phones a thing of the past. But researchers often have to compromise between strength and the ability to self-repair when developing these materials. Now, one group reports in ACS Nano the development of a smart coating that is as hard as tooth enamel on the outside but can heal itself like skin can.

Engineers 3-D print shape-shifting smart gel

3D printing becomes 4D as objects morph over time and temperatures change. Rutgers engineers have invented a “4D printing” method for a smart gel that could lead to the development of “living” structures in human organs and tissues, soft robots and targeted drug delivery.

Applying Machine Learning to the Universe’s Mysteries

Berkeley Lab scientists teach machines to analyze simulations of exotic subatomic ‘soup.’ Computers can beat chess champions, simulate star explosions, and forecast global climate. We are even teaching them to be infallible problem-solvers and fast learners.

NTU scientists create customizable, fabric-like power source for wearable electronics

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have created a customizable, fabric-like power source that can be cut, folded or stretched without losing its function. Led by Professor Chen Xiaodong, Associate Chair (Faculty) at the School of Materials Science & Engineering, the team reported in the journal Advanced Materials (print edition 8 January) how they have created the wearable power source, a supercapacitor, which works like a fast-charging battery and can be recharged many times. Crucially, they have made their supercapacitor customizable or “editable”, meaning its structure and shape can be changed after it is manufactured, while retaining...
