Nanoconfined Cu─O─Mo Asymmetric Sites Enable Ambient Spontaneous O2‐to‐1O2 Conversion for Sustainable Water Purification

Advanced Materials, Volume 38, Issue 5, 22 January 2026.
An asymmetric Cu+─O─Mo6+ dual‐site in a nanoconfined membrane turns O2 into singlet oxygen at ambient conditions with ≈95% selectivity, bypassing superoxide. It concentrates reactants for rapid pollutant removal, operates stably in continuous flow with ultra‐low metal leaching and cost, efficiently purifying complex waters.

REEP1 Accumulation Disrupts ER Integrity and Drives Spinal Motoneuron Degeneration in Distal Hereditary Motor Neuropathy

Advanced Science, Volume 13, Issue 2, 9 January 2026.
REEP1 contributes to endoplasmic reticulum (ER) shaping. Variants either cause cortical motoneuron degeneration and hereditary spastic paraplegia (HSP) or spinal motoneuron degeneration and distal hereditary motor neuropathy (dHMN). Knockout causes less complex ER structures and cortical motoneuron loss.

Boosting Nanofiltration Membrane Selectivity via Amine‐Polymer Additive Engineering for Efficient Lithium Extraction From Brine

Advanced Science, Volume 13, Issue 3, 14 January 2026.
A diffusion‐controlled interfacial polymerization strategy incorporating poly(allylamine) (PAA) into piperazine (PIP) solution enables precise tuning of amine monomer diffusion and polyamide (PA) network formation with trimesoyl chloride (TMC). The resulting nanofiltration membranes exhibit crumpled morphology, appropriate surface charge, and enhanced ...

Nanoscopic Mapping of the Extracellular Space in Amyloid Plaque‐rich Cortex

Advanced Science, Volume 13, Issue 1, 5 January 2026.
The extracellular space and diffusion around amyloid plaques are examined using shadow imaging and single‐particle tracking. Increased diffusivity is found near plaques, extracellular matrix alterations, and plaque core penetrability that varies with amyloid phenotype.
