متن کاملA ball valve micropump in glass fabricated by powder blasting
We present the microfabrication and characterization of a ball valve micropump in glass, which is magnetically actuated using the sinusoidal current of an external electromagnet. We employ the use of a simple powder blasting technology for microstructuring the glass substrates and fusion bonding for assembly of the multi-layered microfluidic chip. The use of a polymer membrane with embedded per...
متن کاملParoxysmal atrial fibrillation after smokeless tobacco (Maras powder) use.
Use of cigarettes and smokeless tobacco is a considerable public health problem. In Turkey, a type of smokeless tobacco called Maras powder (MP) is widely used in the Southeastern region. We present a case of paroxysmal atrial fibrillation that was suspected to be caused by the use of MP, which has never previously been noted in the literature. A 46-year-old man was admitted to our emergency de...
متن کاملAn analytical model for mechanical etching of glass by powder blasting
A nonlinear hyperbolic partial differential equation modelling the etching of glass by powder blasting is proposed. This equation is solved by means of the characteristic strip equations. The analytical solution is in reasonable agreement with measurements. AMS Subject Classification: 35F25, 35L60, 33C05.
متن کاملFabrication of Biochips with Micro Fluidic Channels by Micro End-milling and Powder Blasting
For microfabrications of biochips with micro fluidic channels, a large number of microfabrication techniques based on silicon or glass-based Micro-Electro-Mechanical System (MEMS) technologies were proposed in the last decade. In recent years, for low cost and mass production, polymer-based microfabrication techniques by microinjection molding and micro hot embossing have been proposed. These t...
