Nonetheless, large forces must be applied to overcome the residual friction. Furthermore, results largely vary from sample to sample, because friction strongly depends on the chemical and physical properties of the surfaces (notably, surface roughness and water contamination).

Background: When working with carbon particles, the traditional manufacturing techniques require preparation of slurries that are afterwards coated onto a surface. With this method, only planar structures (layers) can be created. When three dimensional microstructures are needed, one of the options is micromolding, which usually results in arrayed structures that contain defects in the individual rods due to the difficult deposition of the particles into the micromold, even when using centrifug

Background: Current dampers with controllable damping curves, e.g., magnetorheological fluid (MRF) dampers, are primarily hydraulic dampers, which are based on viscous flow through orifices. The viscous-flow dissipates energy by the internal friction mechanism of the fluid, converting external energy to thermal energy totally. However, increased temperature degenerates the damping efficiency of dampers through decreasing the viscosity of the fluid. The damper efficiency is defined as the ratio

Background: Materials with a grain size smaller than one micron, and larger than a nanometer, are known as ultra-fine grained materials. Ultra-fine grained materials are attracting considerable amounts of interest primarily due to their superior properties in strength, ductility, formability, fatigue, and wear resistance. Following the Hall-Petch relationship, as the material's grain size decreases, its strength increases. Therefore, by reducing the grain size of a material below one micron, th

Background: Piezoresistive accelerometers are traditionally fabricated by doping selected areas of wafer to achieve isolated pn-junctions. Often, two separate doping steps are employed to obtain both highly-doped conductors as well as lightly-doped piezoresistors. Once the piezoresistors and conductors have been defined, additional fabrication steps are required to etch the suspension system as well as the free-standing proof mass, which normally deflects in the out-of-plane direction.

In a vacuum, light propagates with a constant velocity, while in an optically transparent non-dispersive media, the speed of light propagation can be different. At optical frequencies, the refractive index of transparent materials usually does not exceed several units, and the speed of light propagation is of the same order of magnitude as the speed of light in vacuum.
The situation can change dramatically in strongly dispersive media. Although the phase velocity of light is still determined

Background: In the past, for micromachined gyroscopes to operate with highest precision required characterization by the manufacturer followed with post processing such as laser trimming, ion beam milling or selective material deposition and integration of feedback control. This process is expensive and time consuming and contributes to additional costs of the sensor. Another disadvantage is this type of post processing is exclusively done by the manufacturer under ideal laboratory conditions.
