Magnetic microactuation systems of torsion silicon cantilever is described. Devices are constructed in a batch fabrication process which combines electroplating with conventional photolithography , materials, and equipment. The magnetic transducers are applied to generation of motion in micromechanical structures such as cantilever, beam, membrane. Microelectromechanical systems (MEMS) with mag...

Large-area transmission dynodes were fabricated by depositing an ultra-thin continuous film on a silicon wafer with 3-dimensional pattern. After removing the silicon, corrugated membrane enhanced mechanical properties was formed. Mechanical materials, such as this membrane, are engineered to improve its strength and robustness, which allows it span larger surface in comparison flat membranes wh...

Precipitate-free Fe-Cr-Ni f.c.c. alloys exhibit strong intergranular corrosion in acid solutions at electrochemical potentials from the transpassivity range. Segregation of impurity atoms to grain boundaries is generally considered to be responsible for this specific kind of localized damage. A study of the influence of silicon, phosphon~s and carbon on the intergranular transpassive corrosion ...

In this study, two silicon-containing steels with different P contents were used, and reheating tests were conducted in an industrial furnace in a hot strip plant. The effect of P on the microstructure and melting temperature of Fe2SiO4 in silicon-containing steels was investigated using a backscattered electron (BSE) detector and energy-dispersive spectroscopy (EDS). The melting process of Fe2...

in the current research, polyvinylchloride based mixed matrix heterogeneous anion exchange membranes were prepared by a solution casting technique. titanium dioxide nanoparticles were also utilized as inorganic filler additive in the membrane fabrication. the effect of tio2 nanoparticles concentration in the casting solution on the membrane physico-chemical properties was studied. membrane wate...

Solid-state nanopores can be used to detect nucleic acid structures at the single molecule level. An e-beam has been used to fabricate nanopores in silicon nitride and silicon dioxide membranes, but the pore formation kinetics, and hence its final structure, remain poorly understood. With the aid of high-resolution TEM imaging as well as TEM tomography we examine the effect of Si3N4 material pr...
