Polymer-free nanofibers from vanillin/cyclodextrin inclusion complexes: high thermal stability, enhanced solubility and antioxidant property [PDF]

open access: yes, 2016
Vanillin/cyclodextrin inclusion complex nanofibers (vanillin/CD-IC NFs) were successfully obtained from three modified CD types (HPβCD, HPγCD and MβCD) in three different solvent systems (water, DMF and DMAc) via an electrospinning technique without ...

Advancing Biomass Valorization via Electrocatalytic Oxidation: Design Principles, Emerging Challenges, and Future Perspectives

open access: yesSusMat, EarlyView.
This review categorizes substrates for electrocatalytic biomass valorization by carbon chain length into C2–C3 alcohols, C5–C7 cyclic compounds, and Cn biopolymers. It identifies four universal catalyst design principles: optimizing intermediate adsorption, engineering synergistic multi‐type active sites, accelerating active‐site formation, and ...

4-Amino-5-(2-hydroxybenzylideneamino)benzene-1,2-dicarbonitrile

open access: yesActa Crystallographica Section E, 2009
A new tetradentate unsymmetrical Schiff base, C15H10N4O, has been synthesized from 4,5-dicyano-o-phenylenediamine and o-vanillin in refluxing ethanol. The dihedral angle between the two benzene rings is 39.0 (1)°.

Yeast Knockout Strain Collection: Driving Functional Genomics, Biotechnological Applications and Human Disease Research

open access: yesYeast, EarlyView.
ABSTRACT The knockout strain collection of Saccharomyces cerevisiae has served as a valuable resource for functional genomics and yeast‐based biotechnology studies. A comprehensive single‐gene knockout strain collection, covering nearly all non‐essential genes, together with complementary mutant collections for essential genes, including temperature ...
