We have determined the influence of reference particle deformability and suspending buffer tonicity on the measurement of lymphocyte volume by an electronic particle volume analyzer. When the volume analyzer was standardized with latex spherules having a shape factor (fe) of 1.5, red cell volume was 96 cu micron and lymphocyte volume was 289 cu micron. The red cell volume corresponded closely t...

Lead free potassium sodium niobate (KNN) piezoceramics were synthesized via conventional solid state sintering route. Nano and micron WO3 were separately added to KNN through ball-milling. Dielectric and piezoelectric properties of samples sintered in the temperature range of 1110°-1145°C were measured by precision LCR-meter and APC d33-meter devices. The results revealed that micron WO3 partic...

The bone ablation characteristics of five infrared lasers, including three pulsed lasers (Nd:YAG, lambda = 1,064 micron; Hol:YSGG, lambda = 2.10 micron; and Erb:YAG, lambda = 2.94 micron) and two continuous-wave lasers (Nd:YAG, lambda = 1.064 micron; and CO2, lambda = 10.6 micron), were studied. All laser ablations were performed in vitro, using moist, freshly dissected calvarium of guinea pig ...

New technologies for accurately measuring corneal shape and full eye aberrations are now available. An algorithm that uses these technologies to predict the amount of ablation needed to produce a corneal surface that optimally focuses light is developed. It is found that knowledge of the aberrations is far more important than knowledge of corneal shape. Neglect of corneal shape information intr...

Deep sub-micron CMOS technologies provide wellestablished solutions to the implementation of low-noise front-end electronics in various detector applications. The IC designers’ effort is presently shifting to 130 nm CMOS technologies, or even to the next technology node, to implement readout integrated circuits for silicon strip and pixel detectors, in view of future HEP applications. In this w...

CMOS image sensors are today challenging the existing Charge Coupled Devices (CCD) in several application fields. Improved architecture and processes have to a large extent overcome early weaknesses of CMOS imagers, namely with respect to noise and sensitivity. Todays " Active Pixel Sensors" are typically based on sub-micron technologies that have been optimized for optical sensing and can riva...

Innovation often emerges from spin-offs and imitation. Semiconductor processing, as typified by Very Large Scale Integration, is a very mature, high-technology industry, capable of producing components with sub-micron features and extremely closely monitored and controlled chemical compositions. There are many spin-off technologies, some of which have already been adopted in the coatings and me...

Multi shaped beam lithography requires the precise and durable alignment and fixation of MEMS based Multi Deflection Arrays on stable ceramic system platforms using vacuum and high temperature compatible interconnection and joining technologies. Micron accuracy during assembly is accomplished by mark detection using image processing and 3DOF alignment procedures; while interconnection as well a...

We exploit the recent developments of microfluidic technologies to investigate the collective shear-induced diffusion in suspensions of micron-sized particles. Whereas spherical particles do not diffuse on the time scale of our experiments, the results with platelike clay particles show a strong cross-stream shear-induced diffusivity at low volume fraction (phi{0}<or=0.01). Moreover, we find a ...
