Scientific community has received a great deal of attention in the deposition of nano-crystalline diamond films [1-3]. The nano-structure uniformity is the main requirement for industrial application. Therefore, the smoothness and uniformity of grain size is important during synthesis [4-5]. For the deposition of diamond coatings many methods have been employed so far. However, due to superior growth rate, purity and flexibility, the hot filament chemical vapor deposition is preferred for the deposition

Nowadays, in adsorptive separation and purification, activated carbon, zeolites, activated alumina, and silica gels, as existing commercial sorbents, have important roles. However, innovative technological developments are needed in the new economy and under the stringent environmental regulations. Despite very promising features of the newly developed nanostructured sorbent materials, basically exploring and systematic investigations are needed on both synthesis methods and adsorption characteristic

Gluma desensitizer : In 1935, Grossman addressed the requirements for an ideal desensitizing agent as: rapidly acting with long-term effects, non-irritating to the pulp, painless and easy to apply without staining the tooth surface. There are many dentin sensitising agents available which includes oxalates products, calcium phosphate desensitizers; 5% NaF varnish; Glutaraldehyde-HEMA; Gluma,HEMA + other products, NaF; SnF2; light-cured adhesives; glass-ionomer cements; desensitizing dentifrices;

EFFECT OF KAOLIN ON THE MECHANICAL PROPERTIES OF POLYPROPYLENE/ POLYETHYLENE COMPOSITE MATERIAL Samir Nassaf Mustafa ABSTRACT :- In this work, the mechanical and water absorption properties of polymer blend polypropylene (PP) and low density polyethylene (LDPE) at constant ratio (50/50) composites as a function of kaolin powder weight content in the grain size (100,120 µm) were investigated. Polymer composite was fabricated by mixing polymer blend ( PPLDPE) with (0, 1, 3 ,5, 10, 14) wt.% of kaolin

Friction stir welding to reduce the grain size and to improve the mechanical properties of FSWed 2014 Aluminum alloy. It is observed that the grain size is decreased to 250 nm under cryogenic process with the liquid nitrogen by using Transmission electron microscope. It is also observed that mechanical properties are enormously improved. The observed grain size and mechanical properties have been correlated with microstructures and fracture features. © 2016 Elsevier Ltd. All rights reserved. Selection

Introduction In many pharmaceutical industries, spray drying is used to create particles that are utilized to form many oral or inhaled drugs. Thus, these particles are designed to be pressed into tablets or dispersed in aerosols. A spray dryer is a processing unit that produces a mist where the solvent is quickly evaporated, leaving particles that are collected in a cyclone. This quick evaporation leaves the molecules fixed in their current positions, preventing the molecules from finding their

is close to 1, the presence of a 2D peak, further associated to interactions between graphene-like planes, suggests a strong graphitic component. Figure (2): The Raman spectrum of AC. Field Emission Scanning Electron Microscope (FE-SEM): The activated carbon was scanned by scanning electron microscopy .Figure (3) showed that the prepared activated carbon had an irregular spherical and porous surface, which indicated high surface area. Figure (3): FE-SEM of AC. Figure (4) showed the

Xylitol is an attractive natural sweetener polyol that is commonly used in a variety of pharmaceutical formulations. The most prominent disadvantage of xylitol in pharmaceuticals is its unsuitability for tableting by direct compression. The objective of this study was to develop stable xylitol particles with modified physical properties, improved compactibility and enhanced biopharmaceutical performance without altering its polymorphic form. Xylitol was crystallized using antisolvent crystallization
