Investigation and comparison of calcium aluminate phases obtained by three methods of sol-gel (with EDTA), sol-gel (without EDTA) and solid-phase synthesis
In this study, we investigate calcium aluminate phases that were prepared by three different solid phase synthesis methods and a sol-gel method (with and without EDTA). The purpose of this study is to compare these three methods in terms of achieving higher purity, optimal phase and complexity in the production of the final product. Comparing the results, we found that the sol-gel method is mo...
متن کاملAlkali cold gelation of whey proteins. Part I: sol-gel-sol(-gel) transitions.
The cold gelation of preheated whey protein isolate (WPI) solutions at alkaline conditions (pH>10) has been studied to better understand the effect of NaOH in the formation and destruction of whey protein aggregates and gels. Oscillatory rheology has been used to follow the gelation process, resulting in novel and different gelation profiles with the gelation pH. At low alkaline pH, typical sol...
متن کاملGlass coating for PDMS microfluidic channels by sol-gel methods.
Soft lithography using polydimethylsiloxane (PDMS) allows one to fabricate complex microfluidic devices easily and at low cost. However, PDMS swells in the presence of many organic solvents significantly degrading the performance of the device. We present a method to coat PDMS channels with a glass-like layer using sol-gel chemistry. This coating greatly increases chemical resistance of the cha...
متن کاملinvestigation on the wettability behavior of CuxO / blackTiO2 photocatalyst nanocomposite on copper foam by combining anodizing and sol-gel methods
Smart materials have been used extensively because of the need for new energy sources. One of the most important types of these materials is the CuxO / blackTiO2 heterogeneous photocatalyst semiconductor. In this study, copper foam was used as a substrate and by performing the anodizing process in a solution of one molar of sodium hydroxide under pulsed and direct currents, a CuxO layer was for...
