Synthesis of Ethyl Methyl Carbonate: Past, Present, and Future

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
Ethyl methyl carbonate (EMC) is the simplest asymmetric organic carbonate, with properties between dimethyl (DMC) and diethyl (DEC) carbonate, considered a unique green liquid organic compound for lithium batteries (electrolyte) and gasoline blending (octane enhancer additive), among other uses. In accordance, the chemical production of EMC is expected

Carcinogenic and anticancer activities of microbiota-derived secondary bile acids

open access: yesFrontiers in Oncology
Secondary bile acids (SBAs), which are metabolites produced by gut microbiota, have been implicated in both carcinogenic and anticancer processes. This review explores the dual role of SBAs, focusing on their molecular mechanisms and biological effects ...

Impact of Hysteresis on Calendar Aging Mechanisms on Three‐Electrode Cells With Silicon‐Rich Anodes

open access: yesBatteries &Supercaps, Volume 9, Issue 8, August 2026.
Strong voltage hysteresis in Si‐rich anodes complicates calendar‐aging analysis, making the assignment of OCV time‐series data to the GITT‐derived OCV curve unreliable and requiring indirect estimation of anode aging. Calendar aging is dominated by irreversible lithium loss caused by continuous SEI growth on the anode.

Operando Raman Spectroscopic Studies on Propane Dehydrogenation Over Co‐Based Catalysts

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 8, Page 1510-1521, August 2026.
Operando Raman spectroscopy was applied to investigate carbon‐containing species during propane dehydrogenation to propene over 3‐wt.% cobalt on silicalite‐1. The emergence of G and D Raman bands correlated with increased propene formation, suggesting that coverage of metallic Co by carbon species may be essential for selective propane dehydrogenation.

Catalyst Hide‐and‐Seek Beneath Porous Support Surfaces: Pinpointing Active Site Distribution Through Resonance Energy Transfer

open access: yesAngewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Like a shark playing hide‐and‐seek in a coral reef, energy transfer (ET) finds hidden “fish” catalysts in the porous support “reef.” ET allows catalytic species to be precisely mapped, revealing whether they reside near the surface, deep in the pores, or are uniformly distributed. This approach ensures controlled catalyst distribution, highlighting how

Pore Size Effect on Melting Point in Saturated Frozen Soil Systems: A Pressure Perspective at Molecular Scale

open access: yesWater Resources Research, Volume 62, Issue 8, August 2026.
Abstract The melting point depression of water confined in porous media with varying pore sizes has been widely observed. Existing models remain insufficient for describing water phase change in smaller pores (i.e., nano pore), where surface effects become significant and water molecules are inhomogeneously distributed near solid surface.

An Ionospheric Storm Scale Index Based on TEC: Comparative Analysis for China Region

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract Defining a standardized ionospheric storm scale is challenging given the ionosphere's inherent complexity and susceptibility to multiple driving factors. In this study, a novel ionospheric storm scale (ISS) index is developed based on statistical analysis of total electron content (TEC) data from 257 ground‐based GNSS stations across China ...

Effectiveness of Family Interventions in Bipolar Disorder: A Systematic Review

open access: yesBipolar Disorders, Volume 28, Issue 5, August 2026.
ABSTRACT Introduction Bipolar disorder (BD) is a chronic mental health condition characterized by extreme mood swings, which significantly affects both the individual and their family system. Given the psychosocial impact of BD on families, family interventions (FI) have emerged as a promising approach to improve treatment outcomes.

Hydroxyapatite–Mesoporous Silica Composites for Dual Quercetin Release and Encapsulation Efficiency

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 4, August 2026.
This study demonstrates that HAP/Si hybrid composites are promising carriers for quercetin delivery, offering high drug encapsulation and tunable pH‐dependent release behavior. Structural characterization confirmed successful composite formation, while release modeling indicated that diffusion and matrix erosion jointly controlled quercetin release ...
