This paper investigates the composition, properties and reactivity of a red mud waste generated in Saudi Arabia with view to find alternative materials replace construction binders high environmental impact. The phase transformation triggered by sintering RM up 1000°C is determined thermal X-Ray Diffraction analyses. Reactivity investigated chemical physical methods including Chapelle test, set...

Mold powders are fluxing agents used as raw materials in the steel industry, which play very important role in processing stability and final surface quality of a product. Surface quality depends particularly on the viscosity and the heat transfer of infiltrated mold flux between the mold wall and the solidified steel shell. Heat flux across the interfacial gap depends on thermal properties of ...

Methods of preparation and application of amorphous form are well established but it is equally important to note that devitrification of amorphous drugs has limited their applications. Present study was performed to investigate mechanism for amorphous drug stabilization using Gelucire in comparison with polyvinylpyrrolidone (PVP). Etoricoxib and celecoxib were taken as model drugs for this stu...

Precision-cut tissue slices of both hepatic and extra-hepatic origin are extensively used as an in vitro model to predict in vivo drug metabolism and toxicity. Cryopreservation would greatly facilitate their use. In the present study, we aimed to improve (1) rapid freezing and warming (200 degrees C/min) using 18% Me(2)SO as cryoprotectant and (2) vitrification with high molarity mixtures of cr...

Abstract:Some types of glass and glass ceramics have a great potential for making bone tissue engineering scaffolds, drug carrier and bone cements as they can bond to host bone, stimulate bone cells toward osteogenesis, and resorb at the same time as the bone is repaired. Calcium phosphate glass ceramics have very attractive properties that allow them to use in bone tissue engineering. Calcium ...
