A review. This research group is working towards understanding the fundamental physicochem. mechanisms of trace metal biouptake by aquatic microorganisms in natural systems. Research is currently focused on identifying under what conditions uptake fluxes a ...
Piezoelectric micromachined ultrasonic transducers for airborne and immersed applications working in the frequency range from 20 kHz in liquid to 750 kHz in air have been fabricated and characterized, as well as simulated by finite element modelling. The b ...
A process to fabricate functional polysilicon structures above large (4 x 4 mm(2)) thin (200 nm), very flat LPCVD silicon rich nitride membranes was developed. Key features of this fabrication process are the use of low-stress LPCVD silicon nitride, sacrif ...
The aim of this work is to describe the structure and the composition of light emitting diode (LED) chips from Rutherford Backscattering Spectroscopy and Particle Induced X-ray Emission measurements performed with a 2 MeV He-4(+) micro-beam focused down to ...
A math. model describing a novel sweeping gas membrane distn. (SGMD) configuration is presented and the sepn. of two volatile components from binary mixts. by this membrane process is theor. investigated. SGMD configuration is modified by using a thermosta ...
The use of photonic crystals (PCs) for realistic light emitting diodes (LEDs) is discussed, given the constraints of planar semiconductor technology. A viable route for the fabrication of high-efficiency high-brightness electrically injected LEDs is presen ...
The construction of enzymatic microsensors based on semiconductor technology and photo-curable membranes is reported in this work. A planar three-microelectrode cell and a pH-sensitive Ion Selective Field-Effect Transistor (ISFET) with Si3N4 membrane have ...
Processing issues for the fabrication of capacitive micromachined ultrasonic transducer (cMUT) arrays have been studied using surface micromachining. This work focuses on the critical steps of process fabrication such as membrane formation, sacrificial lay ...
A review on the methods of characterization of multicomponent microcapsules. Requirements to measure the ingress and egress of small and macromols. through the membrane are discussed, along with the relevant theory. The relevant factors to consider in micr ...
