Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.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.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.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
ESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.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).

Enhancing quality of mental health service for veterans with seizures
Epilepsia, EarlyView.Abstract Psychiatric disorders are commonly identified in people with seizures (PWS). Comorbid mood, anxiety, and trauma‐ and stressor‐related disorders are highly prevalent and not consistently recognized or treated promptly. Veterans with seizures are particularly vulnerable to neuropsychiatric comorbidities, including a higher prevalence of ...
