The present study was concerned with the selection of suitable surfactant for the production of alpha amylase by Bacillus subtilis GCBM-25 in 250 ml shake flask containing 50 ml of fermentation medium. Different surfactants (laundry soap, detergent powder, sulphonic acid, acyle benzene sulphonic acid, liquid soap, Tween 80, sodium silicate, bath soap, sodium tripolyphosphate, sodium lauryl ethe...

Introduction: Primary igneous plagioclase is found in approximately 10 % of type I chondrules in CO chondrites [1]. The presence of plagioclase has potential to help interpret conditions of chondrule formation, if the conditions of plagioclase nuclea-tion and growth are understood. Because primary plagioclase typically contains a significant albite component, the presence of this mineral is sig...

Abstract Although the initial in vitro dissolution of bioactive glasses (BAG) is well characterized, long-term behaviour crystallized BAG scaffolds a continuous fluid flow incompletely understood. A detailed understanding vital for predicting their clinical applications. Here, we explored and reaction mechanisms partly crystalline glass–ceramic based on S53P4 45S5 using flow-through method Tris...

Inorganic adhesives have several benefits over traditional joining methods for joining electrical steels used in magnetic cores of numerous industrial applications. As insulators with very high melting temperatures, the adhesives offer the possibility of increasing the efficiency of these machines. The aim of this project was to characterize sodium silicates as adhesives for such applications a...
