Effect of Graphene Carbon Nitride on Ultraviolet-Curing Coatings [PDF]

Materials, 2019
Graphene carbon nitride (g-C3N4) was successfully prepared by semi-closed pyrolysis and then incorporated into the ultraviolet (UV)-curing system to synthesize different specimens of g-C3N4-hybridized UV-curing (g-C3N4/UV) coatings. The apparent appearance and dispersity g-C3N4 were characterized through X-ray diffraction (XRD), scanning electron ...

Curing of Polyfunctional Spiro Ortho Esters by Carbon Black [PDF]

Polymer Journal, 1986
The crosslinking reaction of polyfunctional spiro ortho esters (SOE) i.e., polymers (resins) that bear SOE structure, by carbon black was investigated. The copolymers of 2-methylene-1,4,6-trioxaspiro[4.6]undecane with vinyl monomers were crosslinked in solution upon heating (150°C) together with carbon black to give gels.

Tailoring the hardening performance and microstructure of calcium aluminate cement through carbonation curing

Case Studies in Construction Materials
The hydration of calcium aluminate cement (CAC) generates metastable phases such as CAH10 and C2AH8, which subsequently transform into more stable products, leading to a reduction in strength and causing volumetric instability.

Influence of carbonation curing on chloride penetration resistance and pore structure refinement in belite-rich cement mortar

Developments in the Built Environment
Concrete is a porous material, and chloride penetration is strongly influenced by its pore structure. Carbonation curing has attracted attention as an innovative curing technique that enhances microstructural densification and CO2 uptake in cement-based ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework

Advanced Functional Materials, EarlyView.
The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
