Electrically Tunable Friction: From Sticky to Slippery with Ionic Hydrogels

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
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.

Gutmann Donor Theory‐Guided Design of Mononuclear Ionic Cluster for Exceptional N‐Type Thermoelectric Ionogel

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Super‐stretchable and self‐healing polyacrylate ternary ionogel elastomers are used for flexible i‐TE devices. Based on Gutmann donor theory of doped anion, the work proposes a three‐parameter tuning strategy of flexible polymer‐doped anion‐synergistic cation to achieve the systematic design of ionic thermoelectric materials.

Effect of extending the oral administration period of 5‐aminolevulinic acid on diagnostic accuracy and treatment outcomes for non–muscle‐invasive bladder cancer

BJUI Compass, Volume 7, Issue 2, February 2026.
Abstract Objectives To evaluate the treatment outcomes of 5‐aminolevulinic acid hydrochloride (5‐ALA) photodynamic diagnosis (PDD)‐assisted transurethral resection of bladder tumour (TURBT) (ALA PDD‐TURBT, hereinafter referred to as ‘ALA‐PDD’) exceeding 4 h after ALA administration for non–muscle‐invasive bladder cancer (NMIBC).

Age‐Specific Survival Estimation of a Eurasian Crane Population Highlights a Long‐Term Decline in Juvenile Survival

Ecology and Evolution, Volume 16, Issue 2, February 2026.
The Eurasian crane (Grus grus), a symbol of conservation success in Europe, has made an impressive recovery. However, our results show that over the study period, juvenile survival declined by almost 30% overall, while sub‐adults experienced a smaller decrease, and adults showed no change.
