Descrizione generale

Drying pearls Orange (Silica gel orange), commonly used as a drying agent in laboratories, is suitable for drying all gases and solids. It is used in desiccators, drying towers, and absorption tubes. Silica gel orange provides longer storage conditions due to its large surface area which enables high absorption capacity. It also changes its color from orange to colorless after moisture absorption (approx. 6 wt% load).

Ricostituzione

regeneration by drying at 130 - 160 °C; do not heat above 160 °C

Codice della classe di stoccaggio

13 - Non Combustible Solids

Classe di pericolosità dell'acqua (WGK)

The low solubility (high durability) of yttrium aluminosilicate (YAS) glass is one of its most important properties for use in in situ radiotherapy. Simple parameters, such as silica or yttria content or network connectivity, are not sufficient to rationalize the

Herein we report the use of mesoporous aluminosilicate (MPAS) for the simultaneous extraction of peptides and lipids from complex body fluids such as human plasma and synovial fluid. We show that MPAS particles, given their mesostructural features with nanometric pore

The aim of this study was to investigate the adhesion of bacteria (Escherichia coli) to pyrophyllite clay using batch and flow-through column experiments. Batch results demonstrated that pyrophyllite was effective in removing bacteria (94.5 +/- 2.0%) from aqueous solution (1

We demonstrate new molecular-level concepts for constructing nanoscopic metal oxide objects. First, the diameters of metal oxide nanotubes are shaped with angstrom-level precision by controlling the shape of nanometer-scale precursors. Second, we measure (at the molecular level) the subtle relationships

Sugar molecules adsorbed at hydrated inorganic oxide surfaces occur ubiquitously in nature and in technologically important materials and processes, including marine biomineralization, cement hydration, corrosion inhibition, bioadhesion, and bone resorption. Among these examples, surprisingly diverse hydration behaviors are observed for
