Topological Defects in Carbon Matrix Are Efficiently Constructed by Joule Thermal Shock for Catalyzing the Growth of Carbon Nanotubes

open access: yesAdvanced Science, EarlyView.
The Joule thermal shock technique ensures the efficient construction of topological defects in the carbon matrix because the instantaneous cooling suppresses the graphitization rearrangement of the heteroatom removal sites. This topological defect carbon can activate carbon source molecules by electron transfer, and further grow into carbon nanotubes ...

NADH‐Reductive Stress Induced by Dihydrolipoamide Dehydrogenase Activation Contributes to Cuproptosis

open access: yesAdvanced Science, EarlyView.
This study demonstrates a cuproptosis mechanism involving nicotinamide adenine dinucleotide (NADH)‐reductive stress in neural cells. Copper activates dihydrolipoamide dehydrogenase under mitochondrial pH, accumulating NADH. Copper also induces mitochondrial permeability transition pore opening, facilitating NADH translocation to the cytosol and ...

Integrated Ultrasound Device for Precision Bladder Volume Monitoring via Acoustic Focusing and Machine Learning

open access: yesAdvanced Science, EarlyView.
We present a conformable wearable ultrasound patch for noninvasive bladder volume monitoring. A flexible PZT array combined with a concave acoustic lens concentrates acoustic energy and improves depth selectivity through the anterior pelvic wall.

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

open access: yesAdvanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

Dilution Effect for High‐Performance Multiple‐Component Near‐Infrared Organic Photodetectors

open access: yesAdvanced Science, EarlyView.
The dilution effect in multi‐component organic photodetector effectively suppresses non‐radiative decay and minimizes dark current, while energy‐level‐offset‐governed electron transfer between acceptors maintains efficient charge transport. This synergistic mechanism collectively enables remarkable device performance, including high detectivity and ...
