A Novel Dual Cross-linking Reagent for Dentin Bonding Interface Stability.
J Dent Res
December 2024
State Key Lab of Supramolecular Structure and Materials, College of Chemistry, Jilin University, Changchun, China.
The cross-linking reagent has been proposed as a means of modifying dentin collagen, inhibiting matrix metalloproteinase activities, and enhancing bond durability during dentin bonding procedures. This study aimed to synthesize an operation-friendly dual cross-linking reagent-3-(4-formyphenoxy)-2-hydroxypropyl methacrylate (FPA)-to assess its ability to cross-link dentin collagen and reduce enzymatic activity at the bonding interface. Cytotoxicity was evaluated by a cell counting kit-8 test and calcein AM/propidium iodide assay.

Two-dimensional inorganic-organic hybrid layered semiconductors are actively studied because of their naturally formed multiquantum well (MQW) structures and associated optical, photoelectric, and quantum optics characteristics. Silver benzeneselenolate (AgSePh, Ph = CH) is a new member of such hybrid layered materials, but has not fully been exploited. Herein, we present a quasi-solution method to prepare high quality free-standing AgSePh flake-like microcrystals by reacting diphenyl diselenide (PhSe) with silver nanoparticles.

Plasmonic systems convert light into electrical charges and heat, mediating catalytic transformations. However, there is ongoing controversy regarding the involvement of hot carriers in the catalytic process. In this study, we demonstrate the direct utilisation of plasmon hot electrons in the hydrogen evolution reaction with visible light.

Pd-based bimetallic or multimetallic nanocrystals are considered to be potential electrocatalysts for cathodic oxygen reduction reaction (ORR) in fuel cells. Although much advance has been made, the synthesis of component-controlled Pd-Sn alloy nanocrystals or corresponding nanohybrids is still challenging, and the electrocatalytic ORR properties are not fully explored. Herein, component-controlled synthesis of PdSn nanocrystals (including PdSn, PdSn, PdSn and PdSn) has been realized, which are grown or deposited on pre-treated multi-walled carbon nanotubes (CNTs) to form well-coupled nanohybrids (NHs) by a facile one-pot non-hydrolytic system thermolysis method.

This study reports on remarkably enhanced oxygen electrocatalytic activity of commercially available Ketjenblack (KB) by growing a non-precious cobalt metal-based zeolitic-imidazolate framework (ZIF-67) at room temperature in methanol solution followed by a mild thermolysis. The resulting Co@CoO nanoparticle decorated nitrogen-doped KB derived from the optimized ZIF-67 : KB weight ratio of hybrid samples at 500-600 °C shows high performance for the oxygen reduction reaction (ORR) with impressive and values of ∼0.
