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.

Ultrathin Monatomic Antimony Films by Sacrificial Atomic Layer Deposition for Phase Change Memory

open access: yesAdvanced Materials, EarlyView.
A three‐step sacrificial atomic layer deposition (s‐ALD) process enables wafer‐scale growth of ultrathin and uniform antimony (Sb) thin films. An ultrathin (≈4 nm) Sb film is uniformly deposited with its characteristic bilayer structure (Sb‐Sb) aligned along the substrate.
