Design, Synthesis, X‐Ray Crystallographic Characterization, Anticholinesterase and Antioxidant Evaluation, and Molecular Modeling of Novel Dispiroindene‐Pyrrolidine Derivatives as Multifunctional Anti‐Alzheimer Agents

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT A novel series of 5‐chloro‐N‐alkyl‐1′,1″‐dimethyl‐4′‐aryldispiro[indene‐2,3′‐pyrrolidine‐2′,3″‐indoline]−1,2″(3H)‐diones (4a–r) was rationally designed and synthesized via a one‐pot multicomponent reaction of N‐alkylated 5‐chloroisatin derivatives, 2‐(arylmethylidene)−2,3‐dihydro‐1H‐inden‐1‐ones (2a–i), and sarcosine (3).

Categorical Boosting‐PSO: A SHAP‐Interpretable Hybrid Framework for High‐Fidelity Wax Appearance Temperature Prediction in Subsea Pipelines

Engineering Reports, Volume 8, Issue 8, August 2026.
CatBoost–PSO accurately predicts wax appearance temperature from oil density, wax content, and pour point temperature, achieving R2 = 0.9760 and RMSE = 1.8106 K. External validation, SHAP interpretation, and low computational cost support rapid wax‐risk screening for subsea pipeline flow assurance.

Identification and correlation of the Aso‐3 tephra in the Omaezaki area, central Japan: A valuable key stratum for the MIS 6/5 transition period

Journal of Quaternary Science, Volume 41, Issue 6, Page 972-986, August 2026.
ABSTRACT The Aso‐3 tephra is one of the most significant widespread marker layers from the Middle to Late Pleistocene, generated by a large caldera‐forming eruption at the Aso volcano in Kyushu, southwestern Japan. Despite its importance, a distal co‐ignimbrite ash correlative has yet to be clearly identified, primarily because although volcanic glass ...

Antimony‐Based Lead‐Free Perovskite Thin Films for Highly Sensitive Ammonia (NH3) Gas Detection

Small Structures, Volume 7, Issue 8, August 2026.
Lead‐free FA3Sb2Br9 perovskite thin films, solution‐processed by spin coating, are introduced as highly sensitive NH3 chemiresistive sensors. At 70°C and 1 V, they show a 235% response to 100 ppm and detect as low as 1 ppm with linear calibration, excellent selectivity, repeatability, and 2‐month stability.
