Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Diverse reactivity of maleimides in polymer science and beyond

open access: yesPolymer International, Volume 74, Issue 4, Page 296-306, April 2025.
This mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...

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‐

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

open access: yesJournal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

A study of the ring opening metathesis polymerization of polycyclic aromatic monomers and cyclopentenes with well defined initiators [PDF]

open access: yes, 1994
This thesis describes studies into the ring opening metathesis polymerisation (ROMP) of polycyclic aromatic monomers and cyclopentenes. Chapter 1 reviews general aspects of ring opening metathesis polymerisation of relevance to the themes of this thesis.

Domino ring-opening metathesis–ring-closing metathesis of bicyclo[2.2.2]octene derivatives: scope and limitations

open access: yes, 2012
Domino metathesis involving ring-opening metathesis–ring-closing metathesis (ROM–RCM) of a bicyclo[2.2.2]octene derivative having an appropriate alkene chain, expected to produce a 7/6 fused bicyclic system, provided a decalin system in contrast to ROM ...

Ultrafast Mechanochemical Synthesis of Plasmonic Transition Metal Nitride Nanoparticles

open access: yesSmall, EarlyView.
Mechanochemistry enables ultrafast synthesis of plasmonic transition metal nitride nanoparticles in minutes rather than hours without external heat supply. The resulting mono‐ and mixed‐metal nitrides display tunable plasmonic absorption, demonstrating a potentially scalable route to refractory plasmonic materials.

Novel tandem ring-opening/ring-closing metathesis reactions of functionalized cyclohexenoids derived from (-)-α-pinene

open access: yes, 2002
The cyclohexenone (+)-2, readily obtained from (-)-α -pinene 1 was elaborated to (+)-3 in an attempt to construct the AB rings of taxoids employing the ring-closure metathesis (RCM) reaction as the key step.
