Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement
Advanced Science, EarlyView.The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

The flocculation of kaolin with polyacrylamides [PDF]
, 1982 Flocculation occurs when high molecular mass organic molecules form bridges between particles, causing them to aggregate. This modifies the sedimentation properties of the mineral slurry.

Advanced Science, EarlyView.Mechanical stress activates BAP31 in chondrocytes. BAP31 competes with ATG14 for binding to STX17, disrupting the STX17–ATG14 complex required for autophagosome–lysosome fusion. The resultant autophagic flux blockade drives the generation of autophagy‐derived exosomes, which mediate pathological cartilage calcification in OA. Chondrocyte‐targeted BAP31

Iron‐Catalyzed Photochemical Degradation of Organics on Mineral Dust Aerosol Particles
Geophysical Research LettersIron is almost ubiquitous in mineral dust aerosol particles and is known to catalyze the photochemical degradation of organics. For the first time we measured the loss of organics in aerosol particles containing various mineral dusts, using citric acid ...

Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming
Advanced Science, EarlyView.This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...
