Application

Cesium hydroxide solution is used to make porous cesium titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes.CsOH impregnated in FAU zeolites enhanced their basic properties without affecting the FAU framework.It can effectively catalyse the condensation of methyl propionate with formaldehyde to yield methyl methacrylate.

In the present work, isopropyl-6-amino-4-(3,5-bis(trifluoromethyl)phenyl)-5-cyano-2-methyl-4H-pyran-3-carboxylate (4H-pyran analog) has been synthesized by a three component reaction catalyzed by CsOH/γ-Al2O3 and characterized. The interaction of 4H-pyran analog with herring sperm DNA (hs DNA) under physiological conditions (phosphate buffer of pH 7.2) was

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
