Bio‐Based Epoxy Resins from Estragole: Achieving High Glass Transition Temperatures Comparable to DGEBA and Simultaneously Low Viscosities

open access: yesMacromolecular Materials and Engineering, EarlyView.
Two novel bio‐based epoxy monomers, diglycidyl‐4‐allylphenol (DG‐4A) and triglycidyl‐diallylphenol (TG‐DA), derived from estragole (92% and 72% bio‐content), were synthesized and cured with isophorone diamin (IPDA) and 4,4´‐diaminodiphenyl sulfone (DDS). The resins show high Tgs, with DG‐4A reaching and TG‐DA exceeding DGEBA‐based systems. These resins

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

open access: yesMacromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...

Advancements in Mass Spectrometry‐Based Glycomics in Food and Nutritional Science

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT This review highlights advancements in mass spectrometry (MS)‐based glycomics in food and nutritional science. Carbohydrates, which are vital for human health, exhibit complex structures, making their analysis challenging. MS has become an indispensable tool for elucidating the structures of carbohydrates, including glycans, through soft ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Underlying Mechanisms of the Treatment Efficacy of (R, S)‐Ketamine for Post‐Traumatic Stress Disorder and Depression: A Review

open access: yesMedicine Advances, EarlyView.
Research shows that (R, S)‐ketamine and its stereoisomers effectively reduce symptoms of post‐traumatic stress disorder (PTSD) and treatment‐resistant depression, with (R)‐ketamine offering similar benefits with fewer side effects. Evidence highlights specific neural circuits and regions, including the dentate gyrus, prefrontal cortex, vCA3, dorsal ...

Residual Chemical Shift Anisotropies in the Structure Determination of Small Molecules

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Plasma neutrophil elastase(ELANE) was markedly elevated in patients with alcohol use disorder, indicating a dysregulated protease‐antiprotease inflammatory balance characterised by decreased SERPINA3. ELANE showed excellent diagnostic specificity(AUC = 0.8683), supporting its potential utility as a neuroinflammatory biomarker for AUD.

Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

open access: yesPolymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐
