Catalyst‐Free Collagen Filament Crosslinking for Engineering Anisotropic and Mechanically Robust Tissue Scaffolds

open access: yesAdvanced Science, EarlyView.
A bioorthogonal rhodamine/PEG crosslinking strategy is introduced to engineer dense collagen hydrogels with high mechanical resilience and cytocompatibility. Integration with wet‐spinning enables the fabrication of uniaxially aligned, cell‐laden collagen filaments that activate mechanotransductive signaling and support functional muscle regeneration in

Targeting Microglial CD49a Inhibits Neuroinflammation and Demonstrates Therapeutic Potential for Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
This study shows that integrin receptor CD49a (Itga1 gene) is significantly upregulated in hyperactivated microglia and microglia‐specific knockdown of Itga1 rescues neuroinflammation and neurodegeneration in a chronic Parkinson's disease (PD) model by targeting PGAM5‐mediated mitochondrial dysfunction and NLRP3 activation. Targeted inhibition of CD49a

Achieving Fast Charging and Superior Cycling Stability Single‐Crystal Ni‐Rich Cathodes by Ultrafast Aqueous Washing

open access: yesAdvanced Science, EarlyView.
Prolonged water washing severely damages the surface layered structure of single‐crystal Ni‐rich cathodes, forming a thick rock‐salt barrier. In contrast, our 3‐min ultrafast washing removes residual lithium while confining surface reconstruction to an ultrathin 2–4 nm layer, thereby unlocking excellent fast‐charging and cycling stability.

Rock Identification [PDF]

open access: yes
This hands-on activity covers the basics of rock identification. After a brief discussion of the terms 'rock' and 'mineral', students will study the characteristics and classifications of the three major rock groups (igneous, metamorphic, and sedimentary)

Multifunctional Tailoring of Fertilizer Composites Directly Derived From Phosphate Rock

open access: yesAdvanced Science, EarlyView.
A novel phosphorus‑sulfur mixed acid with urea (PSU) activation system converts low‑grade phosphate rock (LPR) into multifunctional fertilizer composites (MFCs). MFCs feature porous structures, high nutrient‑activation efficiency, superior slow‑release, and enhanced crop growth, offering a sustainable solution for integrated nutrient management and ...
