Tetraspanin‐ESCRT sorting drives miR‐29b packaging into extracellular vesicles to reverse fibrosis in intrauterine adhesions

open access: yesBMEMat, EarlyView.
MiR‐29b is enriched in extracellular vesicles (EVs) via a tetraspanin transporter‐dependent endocytosis and sorting complex required for the endosomal transport (ESCRT)‐dependent pathway. These EVs target the 3′ untranslated region (3′UTR) of TGFB2, thereby inhibiting the TGF‐β/Smad3 signaling pathway and repairing endometrial damage in intrauterine ...

Intelligent Manufacturing, Industrial Agglomeration, and Green and Low‐Carbon Development: A Nonlinear Path Test Based on the Theory of Ecological Modernization

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Drawing upon ecological modernization theory as the analytical framework, this study employs macro‐level longitudinal tracking data covering China's major regions as research samples. It measures the green and low‐carbon development (GLCD) of manufacturing from the four dimensions—“carbon reduction, pollution mitigation, ecological expansion ...

Breaking trend panel unit root tests [PDF]

open access: yes
This paper proposes Lagrange Multiplier based panel unit root tests allowing for structural breaks through simple extensions of existing group mean and combination tests. The proposed tests are more general than those previously suggested.

Interface Engineering Remarkably Improves the Stability of Fe‐Based Electrode for Alkaline Water Electrolysis at Industrial Ampere‐Level Current Density

open access: yesCarbon Energy, EarlyView.
Interface engineering improves the stability of iron‐based industrial oxygen evolution catalysts by more than 2000 times at ampere‐level current density. ABSTRACT Iron‐based self‐supported electrocatalysts offer cost‐effective oxygen evolution activity but suffer from severe stability degradation under industrial operation.

Interfacial Ru–O–W Orbital Coupling Enables Lattice Oxygen Stabilization for Enhanced Acidic OER

open access: yesCarbon Energy, EarlyView.
A RuO2/WO3 electrocatalyst with strong interfacial Ru–O–W bonds exhibits optimized Ru–O interactions, enhancing intrinsic activity and stability for acidic OER. The WO3 support modulates the electronic structure of RuO2 and promotes oxo‐intermediate deprotonation, delivering a low overpotential of 203 mV at 10 mA cm−2 and sustained operation beyond 200

Spatial Structural Self‐Regulation Engineering Increases Close Pores of Starch‐Derived Hard Carbon for Sodium‐Ion Batteries

open access: yesCarbon Energy, EarlyView.
Spatial structural self‐regulation strategy stimulates the conversion of the hydroxy group (–OH) in starch into carbonyl (–C=O) within a stable three‐dimensional cross‐linking structure. This structure not only reduces the production of water and volatile products, thereby preventing foaming during pyrolysis and improving carbon yield, but also ...

Synergistic Enhancement of Modified‐PVDF Humidity Sensitivity via Chemical Adsorption‐Ionic Conductivity and its Application in Intelligent Powered Air‐Purifying Respirator

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...
