Mechanical stability in flexible perovskite solar cells: Interface engineering and device design

open access: yesFlexMat, EarlyView.
Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of

Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

open access: yesChemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.

Pyridines and Quinolines from 1,3-Dichloro-Trimethinecyanines Pyrimidine and Quinazoline from Azacyanine

open access: yesCHIMIA, 1976
A new synthesis of 2,4-bis(dialkylamino)-pyridines and quinolines is reported. Starting from primary aryl amines or aliphatic imines a mechanism via ynamine-amidines is followed if the cyanine Ia is used as reagent. When the cyanine is substituted, (I.R.

PAF Triggered Pyroptotic NETosis Aggravates Myocardial Ischemia/Reperfusion Injury

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
Platelet activating factor (PAF) secreted by cardiomyocytes during MI/R, drives NETs formation and subsequent NETosis. PAF/NETosis signaling activation is an initiative and causal factor in driving MI/R injury. This study identifies dapagliflozin as a potent NETosis inhibitor, and demonstrates that manipulating PAF‐NETosis signal by dapagliflozin or ...

Reversible Dihydrogen Splitting and Diradical Reactivity of 1,4‐Digermabenzene‐1,4‐diide

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
The diradical reactivity of the 1,4‐digermabenzene‐1,4‐diide, [(ADC)Ge]2, has been demonstrated with a range of substrates. Notably, it undergoes reversible dihydrogen splitting and radical coupling with TEMPO (2,2,6,6‐tetramethylpiperidinyloxyl = RO), forming [(ADC)GeH]2 and [(ADC)Ge(OR)]2, respectively.

Peptidic product derived from trypsin autolysis modulates insect digestive proteases and supports plant biochemical defense

open access: yesPest Management Science, Volume 82, Issue 5, Page 4632-4647, May 2026.
XXXX Abstract BACKGROUND Spodoptera frugiperda, commonly known as the fall armyworm, is a highly economically significant pest that affects various crops, resulting in substantial losses in productivity. Managing this pest primarily relies on chemical insecticides; however, the repeated development of resistance to these chemicals has rendered them ...
