Dextran is a glucose-based polysaccharide widely used in biochemical research, polymer science, biomaterials, transport studies and other laboratory applications. Its combination of high hydrophilicity, broad molecular-weight availability and multiple hydroxyl groups makes dextran a versatile macromolecular platform for both fundamental and applied research. Structurally, dextran is an α-glucan composed predominantly...

Crosslinking agents play an important role in the development of resin-based dental materials. While resin monomers provide the reactive building blocks for polymerization, crosslinking agents help connect polymer chains and create a three-dimensional polymer network. By controlling network structure and crosslinking density, these materials can influence important properties such as...

Overview In H₂O₂-based oxidation processes, sodium tungstate is a commonly used catalyst. However, catalyst cost can become an important consideration when the reaction is transferred to larger-scale production. J&K Metalloenzyme Oxidation Catalyst provides an alternative catalyst option for selected H₂O₂ oxidation systems. In representative applications, the catalyst replacement maintained the...

Introduction The selective oxidation of sulfides to sulfoxides is an important transformation in organic synthesis. Sulfoxides are widely used as pharmaceutical intermediates, synthetic building blocks, and functional sulfur-containing compounds. Hydrogen peroxide (H₂O₂) is an attractive oxidant for sulfide oxidation because it can provide an efficient and relatively clean oxidation pathway....

Introduction The selective oxidation of sulfides to sulfones is an important transformation in organic synthesis. Sulfone groups are widely found in pharmaceutical intermediates, agrochemical compounds, and functional organic molecules. Hydrogen peroxide (H₂O₂) is an attractive oxidant for this transformation because water can be formed as the main reduction by-product. However,...

Dental materials are designed to meet demanding requirements for mechanical performance, stability, aesthetics, adhesion, and long-term performance. While resin monomers, crosslinking agents, and initiators form the fundamental structure and curing system of many resin-based materials, additives play an important supporting role in optimizing formulation performance. Dental material additives can be...
