Chemical cleaning techniques rely on chemical reactions such as chelation, dispersion, hydrolysis, peptization, saponification, and solubilization are some of the approaches employed for permanent ...

From the NMR spectra and the particle size and the polydispersities of the alumina sols, a predominance of alumina particles containing Al 3+ ions with mainly tetrahedral coordination was observed in ...

After assaying bicinchoninic acid, peptization was performed using an S-trap mini (Profiti, USA) according to the manufacturer’s instruction except for the trypsin/LysC setting (1:25 of protease: ...

UP Board Class 12 Chemistry Model Paper 2023: Download the latest model paper for Chemistry released by UPMSP for UP Board Class 12 examinations for the year 2023.

The heat treatment at 60 ºC makes the polymerization quickly and promotes the TiO 2 peptization. After the solvent removal, the powder sample was further heat-treated in order to guarantee the ...

Mastication and peptization are processing stages during which the viscosity of rubber is reduced to a level facilitating further processing (Ref. 14).

Peptization of the precipitate by acetic acid at room temperature transformed it into a transparent alumina sol. The alumina sol was treated with a hydrothermal process. α α -Al 2 O 3 particles ...

What is the definition of ‘Fuel Stability’? Fuels are composed of many constituents such as asphaltenes, maltenes and resins. Asphaltenes are dispersed in a colloidal state into the maltenes phase. In ...
