A microactuator technology utilizing magnetic thin films and polysilicon flexures is applied to torsional micro-structures. These structures are constructed in a batch-fabrication process that combines electroplating with conventional IC-lithography, materials, and equipment. A microactuated mirror made from a 430x130x15 µm 3 nickel-iron plate attached to a pair of 400x2.2x2.2 µm 3 polysilicon ...
A major challenge in high-resolution x-ray free-electron laser-based coherent diffractive imaging is the development of aerosol injectors that can efficiently deliver particles to the peak intensity of the focused X-ray beam. Here, we consider the use of a simple convergent-orifice nozzle for producing tightly focused beams of particles. Through optical imaging we show that 0.5 μm particles can...
objective: this study evaluated the influence of storage time on micro-shear bond strength of two self-etching materials to enamel and dentin. materials and methods: human third molar teeth were sectioned to 1.5 mm thick beams and randomly divided into 2 groups. in group i, se bond and in group ii, tri-s bond was used to bond a composite rod (ap-x) to each treated surface. specimens were prepar...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
We study the phenomenon of synchronization in pairs doubly clamped, mechanically coupled silicon micro-oscillators. A continuous-wave laser beam is used to drive micro-beams into limit cycle oscillations and detect using interferometry. Devices different dimensions are introduce frequency detuning, short bridges connecting as mechanical coupling between oscillators. The region plotted for MEMS ...
A capacitive MEMS (Micro-Electromechanical Systems) accelerometer based on bulk-micromachining technology is generally fabricated using three wafers (glass, silicon, glass), bonded together one on top of the other, forming two sets of parallel plate capacitors: the middle layer is obtained by silicon etching processes and consists of an inertial mass supported by one or more beams (movable elec...
