Studies on Isotope Separation of Lithium by Electromigration in Fused Lithium Bromide and Potassium Bromide Mixture, (III) : Enrichment of Lithium-6

open access: yesStudies on Isotope Separation of Lithium by Electromigration in Fused Lithium Bromide and Potassium Bromide Mixture, (III) : Enrichment of Lithium-6
application/pdf Enrichment of ^6Li by means of electromigration was carried out in fused LiBr-KBr mixture of a composition of 1.54 (Li/K in chemical equivalent ratio). The electromigration brought about by 847, 000 C of charge transported at 520℃, produced in the cathode compartment 38.4 meq.

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

open access: yesChemistryEurope, 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.

Studies on Isotope Separation of Lithium by Electromigration in Fused Lithium Bromide and Potassium Bromide Mixture, (I) Enrichment of Lithium-7

open access: yesStudies on Isotope Separation of Lithium by Electromigration in Fused Lithium Bromide and Potassium Bromide Mixture, (I) Enrichment of Lithium-7
application/pdf Lithium-7 was enriched by electromigration at 500℃ in fused LiBr-KBr mixture. The migration cell was made of Pyrex glass ; zircon sand (100~200mesh) was used for packing material, and graphite rods as electrodes. The electromigration was carried out for 13.4 days at a constant electric current of 165mA. The distribution of the abundance

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide

open access: yesThe 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 ...

Use of Polycyclic Aromatic Compounds as Electrophotocatalysts in Organic Reactions

open access: yesChemistry–Methods, Volume 6, Issue 11, November 2026.
Emerging from the convergence of photoredox catalysis and electrochemistry, electrophotocatalysis is a relatively new and promising synthetic approach in organic chemistry. In this review, the main advantages and the current challenges of this methodology are discussed, while most relevant and late applications of polycyclic aromatic hydrocarbons (PAHs)

A Robust Assay for Molecular Sexing of Emperor Penguins Using Degraded DNA and the Potential Applicability to Other Spheniscids

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
Molecular sexing of birds with intron‐based primers often targets relatively large amplicons that are difficult to amplify with degraded DNA. In this study, we developed a new primer set based on allele‐specific PCR to facilitate sexing of emperor penguins (Aptenodytes forsteri) using non‐invasively collected guano.
