Aplicação

Zinc bromide supported on silica or montmorillonite can be used as a selective catalyst for the bromination of aromatic substrates.

It can be used as starting material to prepare poly(ethylene oxide)/ zinc salt systems, which can be used as polymer electrolytes.

Itcan also be used to prepare ZnO nanoparticles.

Methods of Synthesizing Monodisperse Colloidal Quantum Dots

Colloidal quantum dots (CQDs) are semiconducting crystals of only a few nanometers (ca. 2–12 nm) coated with ligand/surfactant molecules to help prevent agglomeration.

Nossa equipe de cientistas tem experiência em todas as áreas de pesquisa, incluindo Life Sciences, ciência de materiais, síntese química, cromatografia, química analítica e muitas outras.
