Electrically Tunable Friction: From Sticky to Slippery with Ionic Hydrogels

open access: yesAdvanced Materials, EarlyView.
This work demonstrates electrically tunable friction “from sticky to slippery” using ionic hydrogels, achieving reversible more‐than‐fifty‐fold modulation without liquid lubricants. An electric field extracts a salt‐rich interfacial layer that dramatically reduces friction.

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes

open access: yesAdvanced Materials, EarlyView.
Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

Perspective: OLED Displays Singing with the Blues

open access: yesAdvanced Materials, EarlyView.
While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.
