Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Dual‐Phosphorus, Dual‐Nitrogen‐Embedded Corannulene: Synthesis, Structure, and Electronic Coupling

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
P2N2‐TBC, a corannulene‐based bowl structure incorporating two phosphorus and two nitrogen atoms, represents the first P2N2‐embedded heterobuckybowl. The cis and trans stereoisomers of this compound display distinct packing motifs, leading to markedly different electronic coupling patterns.

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Dual‐Molten‐Salt Etching Strategy Enables Built‐in Electric Field in Mo‐MXene/NiFeSe Heterostructure for Superior OER Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
A dual‐molten‐salt etching strategy was employed to construct a built‐in electric field in the Mo‐MXene/NiFeSe heterostructure to achieve excellent oxygen evolution reaction. Transition metal selenides have emerged as potential catalysts for the oxygen evolution reaction, yet their practical implementation faces two fundamental challenges: irreversible

Extraction, Structural Characterization and Anti‐Inflammatory Activity of Polysaccharides From Conioselinum vaginatum

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
This study employed an ultrasonic‐assisted extraction (UAE) method combined with column chromatography purification to obtain two homogeneous polysaccharides (CVP‐I and CVP‐II) from Conioselinum vaginatum, which exhibited distinct physicochemical properties and structural characteristics, and exerted anti‐inflammatory effects by inhibiting the ...
