  • Introduction to Zeolites

    Introduction to Zeolites
    Jul 15, 2018 | ACS MATERIAL LLC

    Zeolites, which are also called molecular sieves, are crystalline microporous materials formed primarily by SiO4 and AlO4 corner-sharing tetrahedral building units that form three-dimensional (3D) frameworks with well-defined channels and cavities of molecular dimensions. The void space within the crystal allows zeolites to discriminate molecules based on their size or geometric shape. With variable chemical compositions and unique pore topologies, zeolites have been utilized in a wide range of industrial applications such as adsorption/separation, ion-exchange processes and also as catalysts …

    May 29, 2018 | ACS MATERIAL LLC

    Facile synthesis of multi-colored, protein-based, metal-free, stable, nontoxic and pH sensitive advanced functional nanoparticles (GlowDots) is now a reality. Controlled cross-linking of bovine serum albumin has resulted in the formation of spherical nanoparticles of 35 nm in diameter with a size distribution of ±10 nm. The nanoparticles are then conjugated with specific dyes to produce white-emitting particles with tunable excitation wavelengths. These nanoparticles are a chemical novelty because their particle size, size distribution, stability, surface chemistry and emission properties …

    FluoDots
    May 22, 2019 | ACS MATERIAL LLC

    FluoDots are single protein nanoparticles labeled with particular fluorescent dyes for imaging and other applications. They are composed of a central protein core surrounded by a covalently attached lipid layer. FluoDots retain the structure and functions of the protein embedded in the core, however the particles have increased thermal stability and a longer shelf life. Numerous carboxylic groups present on the surface of FluoDots are available for further chemical modification of the particles. FluoDot size is tunable at 2.5 Å resolution and the color is tuned independently of the size, …
