چکیده
2 GEL SUPPORT These consist of rectangular pieces of sheet Perspex, and i inch thick, shaped to fit firmly but easily into a Perspex frame. They serve the purpose of raising the gel above the surface of the cutting platform so that it lies proud to the cutting blade (Fig. 1, E). The thickness of the gel support selected allows the precise thickness of the gel slice to be pre-determined. 3 A shallow dish approximately 12 in. square and 3 in. deep, filled with water.

Preparation and Characterization of ZrO2/TiO2 Nanocomposite under Ultrasonic Irradiation by Sol-gel Route
TiO2/ZrO2 nanocomposite was obtained by the sonochemical technique. In this method, two separate gels containing zirconium and titanium were prepared and mixed together. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4. The precursor titanium tetra isopropoxide (TTIP) dissolved in isopropanol. Mixing of Titanium and Zirconium gels was resulted in a yellow TiO2/ZrO2 ...

متن کاملDevelopment of Bioadhesive Transdermal Bupivacaine Gels for Enhanced Local Anesthetic Action
Topical drug dosage forms such as ointments and creams can be easily removed through wetting, movement and contact. The new bioadhesive formulations with enhanced local anesthetic effects are needed for topical administration. The adhesive capacity of hydroxypropyl methylcellulose (HPMC) was determined by measuring the maximum detachment force and the adhesion work with an auto peeling test...

متن کاملPreparation Zirconia Toughened Alumina by Deflocculation-Flocculation Route (TECHNICAL NOTE).
Partially stabilized zirconia (PSZ) agglomerate toughened alumina has been prepared by the "deflocculation-flocculation" technique, using 2 and 3 mol. % Y2O3-doped zirconia powders. Samples containing up to about 30 vol.% zirconia were obtained. The resulting microstructure seems to be mainly influenced by the physical properties of the starting powders, e.g. agglomerate size and the specific s...
