In this study, micro fluid channels are machined on fused silica glass via powder blasting, a mechanical etching process, and the machining characteristics of the channels are experimentally evaluated. In the process, material removal is performed by the collision of micro abrasives injected by highly compressed air on to the target surface. This approach can be characterized as an integration ...

optimization of process parameter is one of the ideal goals in laser sintering. the results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. in this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...

Powder fractions of Dichrostachys glomerata were produced by drying the fruits to 10% moisture, grinding followed sieving differentiate powders sizes <180, 180-212, 212-315 and ≥315 µm, respectively. The obtained analysed for their phenolics profile in vivo antioxidant activities rats evaluated. Lyophilized ethanolic extract crude powder used comparison. phenolic compounds (mg/100 g...

ABSTRACTIn this work, the micro powder was the product of cedar leaf (MPCL) is used as a low-cost adsorbent for the removal of Pb2+ ions from aqueous solutions. Bath experiments were used to determine the best adsorption conditions The adsorption percentage of Pb2+ ions MPCL samples at different initial pH, contact time (tc), adsorbent dosage and temperature (T) were investigated. Effective rem...

A method for the determination of triglycidyl isocyanurate (TGIC) from powder coatings using gas chromatography with mass spectrometric (GC/MS) detection is presented. The new method is considerably easier to use than the existing methods and has superior performance. It has been novelly applied to the determination of TGIC in a variety of occupational hygiene samples (cotton swabs, gloves and ...

In tissue engineering, there is limited availability of a simple, fast and solvent-free process for fabricating micro-porous thin membrane scaffolds. This paper presents the first report of a novel surface suspension melt technique to fabricate a micro-porous thin membrane scaffolds without using any organic solvent. Briefly, a layer of polycaprolactone (PCL) particles is directly spread on top...

Recently, the polymeric micro-fluidic biochip, often called LOC (lab-on-a-chip), has been focused as a cheap, rapid and simplified method to replace the existing biochemical laboratory works. It becomes possible to form miniaturized lab functionalities on a chip with the development of MEMS technologies. The micro-fluidic chips contain many micro-channels for the flow of sample and reagents, mi...
