Achieving Stable Paired Electrolysis of Captured CO2 and 5‐Hydroxymethylfurfural (HMF) via Tuning Anolyte Composition and Anode Surface

open access: yesAdvanced Functional Materials, EarlyView.
Highly stable paired electrolysis of CO2 and biomass‐derived alcohol (HMF) is achieved by replacing conventional alkaline electrolytes with a tailored triethylamine‐carbonate buffer and anion‐conducting ionomer coatings. This configuration effectively mitigates electrolyte degradation and pH instability typically encountered in alkaline CO2 ...

Influence of Dielectric Environment upon Isotope Effects onGlycoside Heterolysis: Computational Evaluation and AtomicHessian Analysis [PDF]

open access: yes, 2019
Isotope effects depend upon the polarity of the bulk medium in which a chemical process occurs. Implicit solvent calculations with molecule-shaped cavities show that the equilibrium isotope effect (EIE) for heterolysis of the glycosidic bonds in 5 ...

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...
