“Naked” Divalent Metal Cations Stabilized by Weakly Coordinating Anions: Syntheses, Properties, and Emerging Applications

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The preparation of soluble and stable metal M2+ dications only stabilized by weakly coordinating anions, that is, M[WCA]2 salts, is an emerging field that, beyond its fundamental interest, holds promise in reactivity due to the high electrophilicity of the central M2+ center.

Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

open access: yesMacromolecular Rapid Communications, EarlyView.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.

Review on Modification of Sulfonated Poly (-ether-ether-ketone) Membranes Used as Proton Exchange Membranes

open access: yesMedžiagotyra, 2015
The proton exchange membrane fuel cell (PEMFC) is a type of modern power, but the traditional proton exchange membranes (PEM) of PEMFC are limited by high methanol permeability and water uptake.

2,3‐Dichloro‐5,6‐Dicyano‐1,4‐Benzoquinone (DDQ)‐Mediated CC Bond Formation: Redox Strategies from Stoichiometric to Catalytic Systems

open access: yesChemistryOpen, EarlyView.
2,3‐Dichloro‐5,6‐dicyano‐1,4‐benzoquinone serves as a versatile oxidant and redox catalyst for CC bond formation through hydride abstraction or single‐electron transfer. Stoichiometric and catalytic systems enable benzylic, allylic, and aromatic CH activation under mild, metal‐free conditions, providing sustainable routes to complex and bioactive ...

Macroscopic CNT fibres inducing non-epitaxial nucleation and orientation of semicrystalline polymers [PDF]

open access: yes, 2015
In the presence of macroscopic fibres of carbon nanotubes (CNT), various semicrystalline polymers are shown to present accelerated crystallisation through the formation of a transcrystalline (TC) layer perpendicular to the fibre axis. From differential

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 ...
