According to the manufacturer (Kodak pathe) of the LR-115 Type 2 films, which are widely used in environmental radioactivity studies, the exposed films should be etched in 10% solution of NaOH, while the temperature of the etching solution is to be kept at 60C. The optimum time of etching depends on different conditions; like geometry of the bath, temperature etc. To determine the optimal etchi...

Cadmium compounds such as cadmium sulfate are used in batteries, pigments and in semiconductor industry. Commercially available cadmium sulfate was purchased and used for the crystal growth. The sample in salt form was dissolved in double distilled water and the saturated solution was prepared. Nearly 38 grams/50 ml are necessary to prepare the saturated solution and the solution was stirred we...

A signal amplification strategy based on bio-bar-code functionalized magnetic nanoparticles as labels holds promise to improve the sensitivity and detection limit of the detection of DNA hybridization and single-nucleotide polymorphisms by flow injection chemiluminescence assays.

With polylactic-co-glycolic acid(PLGA) as shell material of microcapsule, amoxicillin as the model, poly(vinyl alcohol) and twain as surfactant, amoxicillin-PLGA microcapsules were manufactured using digital micro-jetting technology and a glass nozzle of 40μm diameter. The influences of the parameters of micro-jetting system on the mean grain size and size distribution of amoxicillin-PLGA micro...

This paper presents a feature analysis of two electromagnetic interference test facilities. The one is an anechoic chamber and the other is a reverberation chamber. And then, this paper reviews problems of the current reverberation chamber, the stirrer. In general, a reverberation chamber uses a stirrer to generate a uniform electric field inside it. However, the stirrer is a big sized unit and...

We report the design, fabrication, and testing results of a micro magnetic stir-bar monolithically integrated in Parylene surface-micromachined channels with small tip-tochannel clearance. We demonstrated two applications of such stir bars: mixing and pumping.

Purpose Magnetic coupling is one of the few strategies to transmit motion through physical obstacles. This approach can be applied to remotely control and manipulate medical devices/robots inside the human body preventing the need for dedicated incisions [1, 2]. The most straightforward approach to take advantage of magnetic coupling to control a medical device inside the human body consists in...
