Micro-algae have received considerable interest as a potential feedstock for producing sustainable transport fuels (biofuels). The perceived benefits provide the underpinning rationale for much of the public support directed towards micro-algae research. Here we examine three aspects of micro-algae production that will ultimately determine the future economic viability and environmental sustain...

We developed a new biosensor device for environmental gas/liquid toxicity sensing, which utilizes the chemotaxis of microbial cells confined in a micro-aquarium. The device has an isolated micro-aquarium to confine microbial cells separately from flowing gas/liquid in two bypass microchannels, and the molecules of the flowing gas/liquid permeate from the microchannels into the micro-aquarium th...

The reliability of MEMS based systems might be increased by the use of a Physics of Failure (PoF) methodology. This methodology necessitates the development of corresponding models that can be used for reliability evaluation. The model development is based on a good knowledge of effects of environmental influences on the MEMS. For the reliability evaluation of MEMS based systems the used models...

The sensitivity analysis of atomic force microscope (AFM) based manipulation of gold spherical nanoparticles in air medium has been carried out in previous research works. In the AFM-based manipulations conducted in various biological liquid mediums, the new environmental parameters associated with these biological fluids also affect the dynamics of the manipulation process. Therefore in this r...
