General description

Atomic number of base material: 64 Gadolinium

Application

In many asymmetric catalysis applications, glove box and Schlenk techniques should be employed to prevent exposure of the rare earth catalyst to air and moisture, which can be detrimental to the reaction outcome. Solutions of the catalyst should be made using anhydrous solvents and used shortly after preparation.

The objectives of this study were to assess demineralized dentin porosity and quantify the different porous features distribution within the material using mercury intrusion porosimetry (MIP) technique. We compared hexamethyldisilazane (HMDS) drying and lyophilization (LYO) (freeze-drying) in sample preparation. Fifty-six

High-density live cell array serves as a valuable tool for the development of high-throughput immunophenotyping systems and cell-based biosensors. In this paper, we have, for the first time, demonstrated a simple fabrication process to form the hexamethyldisilazane (HMDS) and poly(ethylene

Bulletin of experimental biology and medicine, 151(3), 378-382 (2012-03-28)
We compared conventional method for specimen (cell cultures, tissue specimens) preparation for scanning electron microscopy and a method without sputtering and critical-point drying. OTO-method (osmium-thiocarbohydrazide-osmium) with sample impregnation with hexamethyldisilazane followed by air drying was used as an alternative method.
