High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells

Advanced Science, EarlyView.
High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Operando Raman Spectroscopy Reveals Backpressure‐Controlled Dynamics in Diluted CO2 Electrolysis

Advanced Science, EarlyView.
High backpressure operation governs the CO2 reduction reaction (eCO2RR) kinetics and selectivity, as well as the CO2 and water dynamics, as revealed through operando Raman spectroelectrochemical measurement. Operating eCO2RR near diffusion‐limited conditions provides a platform for investigating the competition between eCO2RR and the hydrogen evolution

Leonurine Ameliorates Doxorubicin‐Induced Cardiotoxicity via STING/NF‐κB/NLRP3 Inflammasome Signaling Pathway

Advanced Science, EarlyView.
ABSTRACT Doxorubicin‐induced cardiomyopathy (DIC) remains a dose‐limiting clinical challenge. This study reveals that cardiac vascular endothelial cells (CVECs) act as initial sensors of doxorubicin cardiotoxicity: circulating doxorubicin activates the cGAS‑STING pathway in CVECs, triggering NLRP3 inflammasome‑mediated pyroptosis and release of ...

The effects of the purge flow rate and its flow orientation in the atomic layer deposition (ALD) simulations of aluminium oxide (Al2O3)

, 2019
: With the recent increase in the scaling down of devices, there has been an immense increase in the need for nanotechnology. Nanoscale devices should have their layers of materials as thin and uniform as possible.
