Fast One‐Step Microwave Synthesis of 2H–1T MoS2 for Efficient Hydrogen Evolution

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
MoS2 nanoflakes were rapidly synthesized in a microwave hydrothermal reactor for HER catalysis in a single 15‐min step. For the first time, in situ monitoring of synthesis parameters was performed using a camera, while XPS and XRD analyses confirm that the process forms MoS2 nanoflowers with mixed 2H–1T seeds, directing the subsequent growth of pure 1T

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

open access: yesDrug 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).

Do Acceptance‐ and Mindfulness‐Based Interventions Improve Psychological Flexibility in People With Chronic Pain? A Systematic Review and Meta‐Analysis of Randomized Controlled Trials

open access: yesEuropean Journal of Pain, Volume 30, Issue 7, August 2026.
ABSTRACT Background Acceptance‐ and mindfulness‐based interventions are effective for improving pain‐related outcomes, yet their effects on psychological flexibility have not been meta‐analyzed. This systematic review and meta‐analysis addressed this gap by comparing these interventions with control conditions on psychological flexibility and its core ...

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 8, Page 1463-1480, August 2026.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Synergetic Ruthenium Clusters and Ligand Motifs in Insoluble Polyoxometalates for Efficient Urea Electrosynthesis

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.

Testing for Conformity With Parametric Distributions Using Level Sets: From Univariate to Bivariate Applications

open access: yesStatistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT Conformity of observed data with a postulated probability distribution is a fundamental problem of statistical modeling. Current tools for checking distributional conformity are often limited to univariate settings, with extensions to multivariate distributions facing challenges in interpretability and power.

Cumulative Adverse Childhood Experiences and Multiple Neurodevelopmental Disorders in Children and Adolescents: A Population‐Based Study

open access: yesStress and Health, Volume 42, Issue 4, August 2026.
ABSTRACT Adverse childhood experiences (ACEs) and neurodevelopmental disorders (NDDs) are frequent yet the relationship between cumulative ACEs and multiple NDDs remains poorly understood. Using data from 120,629 children aged 3–17 years in the 2021‐2023 US National Survey of Children's Health, we examined associations between ACEs and multiple NDDs ...
