Precision Profiling of α‐1,4‐ Versus α‐1,6‐Glycosidase Activity Through Synthetic Linear and Branched Glycogen Tetramers Using Cyclic Ion Mobility Mass Spectrometry and High‐Performance Liquid Chromatography‐Mass Spectrometry

ChemistryEurope, Volume 4, Issue 11, November 2026.
Synthesis of glycogen‐like tetrasaccharides allowed the design of an integrated HILIC‐MS/cyclic ion mobility MS workflow to characterize glycosidase specificity. HsGDE selectively hydrolyzed α‐1,6 branches, whereas yeast α‐1,4‐glucosidase preferentially cleaved α‐1,4 linkages, and the rice enzyme showed broader regioisomeric activity.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5921-5930, November 2026.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Step‐Associated Cu‐Ceria Interfaces Enhance Catalytic Activity and Selectivity

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
The catalytic activity and selectivity of supported Cu nanoparticles depends on their interfacial environments, with Cu nanoparticles at step‐associated environments converting CO2 to methanol much faster than those on terrace facets, indicating that step sites create more active metal–oxide interfaces.

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5954-5978, November 2026.
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Highly Permeable CeO2 Porous Hollow Microspheres with Multilevel Gas Channels for Rapid NH3 Gas Response and Recovery Performance

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
In this study, a series of highly permeable CeO2 porous hollow microspheres with multilevel gas channels and tunable pore sizes were first prepared via the hydrothermal method, achieving rapid response and fast recovery to ammonia gas. Fast response and recovery performance is highly significant for real‐time monitoring of NH3 gas due to the toxic and ...

Nitrogen‐Doped Mesoporous Carbon Loaded With Zn Single Atoms as a Catalyst for the Synthesis of 2,4(5)‐Diarylimidazoles

ChemistryOpen, Volume 15, Issue 11, November 2026.
A zinc single‐atom catalyst anchored on nitrogen‐doped mesoporous carbon (Zn@NMC) was synthesized via an evaporation‐induced self‐assembly method and applied in the one‐pot synthesis of 2,4(5)‐diarylimidazoles. The catalyst was fully characterized using FT‐IR, XRD, SEM, EDX, BET, and TGA analyses.

High‐Pressure Synthesis of Quantum‐Stabilised Manganese Superhydride MnH7

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Superhydrides are a rarity in transition metal hosts. Through high‐pressure, high‐temperature diamond anvil cell studies, the most hydrogen‐rich transition metal hydride, MnH7${\rm MnH}_7$ has been synthesised. Density functional theory calculations demonstrate that zero‐point energy stabilises the crystalline structure that MnH7${\rm MnH}_7$ adopts ...

Synthesis of S‐Arylthioxanthonium Trifluoromethanesulfonates From Thioxanthones and Diaryliodonium Salts by Copper(II) Catalysis and Application to Aryl–Heteroaryl Bond Formation by Direct LED Irradiation

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
A straightforward Cu(II)‐catalyzed synthesis of S‐arylthioxanthonium trifluoromethanesulfonates from readily available thioxanthones and diaryliodonium salts is described. A broad range of salts is obtained in moderate to good yields. It is further demonstrated that S‐arylthioxanthonium trifluoromethanesulfonates act as aryl radical precursors under ...

Synthesis of S‐Linked Glycoconjugates of Monosaccharides and Levoglucosenone Derivatives Through Photoinduced Thiol–Ene Reaction Mediated by 4CzIPN and Its Water Soluble Analog

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
Visible‐light thiol–ene reaction mediated by 4CzIPN enables access to hydrolytically stable S‐linked glycoconjugates from levoglucosenone‐derived thiols (Y = 91% to quant. d.r. = up to >95:5) and conventional thio‐sugars (Y = 80% to quant. d.r. = up to >95:5).
