Innovating Electrosynthesis From Metal Electrodeposition to Organic Chemistry: Deep Eutectic Solvents as Efficient and Sustainable Media

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
This review analyzes deep eutectic solvents (DESs) as efficient media for both organic and inorganic electrosynthesis. The improvements in terms of synthetic opportunities and sustainability are discussed, by exploring the multiple roles of DESs as solvents, electrolytes, and promoters, enabling effective and selective electrosynthesis under mild and ...

Counterion Effects Enable Divergent Pd‐Catalyzed Carbonylative Cyclization of Amide‐Tethered o‐Alkynylphenols

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
The catalytic carbonylation of alkynes is a powerful route to heteroaromatic scaffolds, yet achieving regioselectivity remains challenging. Herein, we report a divergent carbonylative cyclization of 2‐alkynylphenol derivatives that affords either coumarins (6‐endo‐dig) or 2‐coumaranones (5‐exo‐dig) by tuning the palladium‐based catalytic system. Pd(OAc)

T‐Cell Exhaustion in the Tumor Microenvironment: Subcellular Dysfunction, Pan‐Cancer Characteristics, and Therapeutic Interventions

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing

Neurocognitive Aging Following Acute Illness: Pathobiology and a Framework for Developing Neurotherapeutic Agents

open access: yesBrain and Behavior, Volume 16, Issue 6, June 2026.
In this review, we discuss the scientific basis for how neurocognitive aging occurs after critical illness, including sepsis, trauma, and burns, and the clinical need to develop therapies to reduce inflammation, protect the blood–brain barrier, remove senescent cells, and enhance neuroplasticity.

Carboxylated Carbon Nanotube‐Supported Copper‐Indium Bimetallic Catalysts for Electroreduction of CO2 to Dimethyl Carbonate via Membrane‐Free Cascade Electrosynthesis

open access: yesCarbon and Hydrogen, Volume 28, Issue 2, Page 226-243, June 2026.
A membrane‐free cascade electrocatalytic system with Cu100In50‐(COOH)CNTs converts CO2 to CO and then couples with alcohols to yield DMC (52.3% FE) and DEC (27.8% FE) via carboxyl‐Cu‐In synergistic regulation of intermediate adsorption. ABSTRACT Under the background of the dual carbon strategy, upgrading CO2 electroreduction from C1 products to high ...

A Spectral Matching Algorithm Based on the Wasserstein Metric

open access: yesJournal of Chemometrics, Volume 40, Issue 6, June 2026.
ABSTRACT Through visual inspection, scientists can easily judge the similarity of pairs of spectra from different sources, whether they are experimental measurements, spectra libraries, or spectra calculations. Spectral similarity is recognized when the peak patterns appear similar, even if the peak positions are shifted or the peak amplitudes are ...

Stabilization of Pd Active Sites by Defective NaY Zeolite Framework for Enhanced Stability in Dimethyl Carbonate Synthesis

open access: yesEcoEnergy, Volume 4, Issue 3, June 2026.
A tailored‐defect strategy employing sequential high‐temperature calcination and acetylacetone treatment was developed to generate framework defects in NaY zeolite while preventing the formation of strong acid sites. These defects facilitate electron transfer from Pd to the zeolite framework and stabilize the Pd2+ active sites, thereby conferring ...
