A solid and bench-stable alternative to sulfuryl fluoride gas has been developed, 4-(Acetylamino)phenyl]imidodisulfuryl difluoride (ASIF). ASIF is a shelf-stable, crystallilne reagent for the installation of the valuable SO2F functional group.

The diversity of applications and nanostructured materials accessible using ultrasonic spray methods are highlighted in this article.

Ultrasonic spray pyrolysis (USP) is effective for preparing a wide array of materials and is scalable and continuous. Nanomaterials prepared by USP include nanoporous metal oxides and sulfides, nanocomposites, semiconductor quantum dots, and conductive metal inks.

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