Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

open access: yesJournal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,

Efficient Solar‐Driven Interfacial Steam‐Electricity Co‐Generation by Modular Design of CAU‐23/Graphene Hybrid Evaporator

open access: yesCarbon Energy, EarlyView.
A dual‐functional evaporator based on CAU‐23/graphene hybrid is acquired through a modular design strategy. Owing to superior broadband light absorption, optimal wettability, and porous architecture that synergistically integrates nanoconfined ionic channels with photothermal conversion, it exhibits a high evaporation rate of 2.71 kg m−2 h−1 with the ...

Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

open access: yesChemistry – A European Journal, EarlyView.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Experimental methods in chemical engineering: Cyclic voltammetry—CV

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...
