Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance
The hydroxyl groups in (EOA)2PbBr4 enable a rearrangement of the polar MA+ ions in MAPbI3, which enhances the Ps‐electric field and promotes the separation of photogenerated carriers. Consequently, the (EOA)2PbBr4/MAPbI3 composite exhibits the enhanced CO production yield in photocatalytic CO2 reduction reactions.

Sequential ultrafast excitation is shown to increase the relative kinetic weighting of biexciton‐mediated decay in CsPbBr3 nanocrystals without increasing the total excitation fluence. By temporally structuring excitation within the exciton lifetime, the early‐time fast decay contribution becomes more pronounced while the fitted fast decay constants ...

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).

Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors
A hybrid dual‐switching‐frequency inverter for SRMs is proposed, combining SiC and IGBT devices based on rotor inductance. The method enables accurate current tracking with simple hysteresis control, significantly reducing torque ripple, vibration, and acoustic noise while cutting inverter cost compared to full‐SiC solutions.
