An ISFET is an ion-sensitive field effect transistor used to measure ion concentrations in a solution; when the ion concentration changes, the current through the transistor will change accordingly. Here, the solution is used as a gate electrode. A voltage between substrate and the oxide surfaces arises due to an ions sheath. The surface hydrolization of the OH groups of the gate materials ...

In this section, we design an invisible cloak using the composite medium of silver nanowires with elliptical cross-sections embedded in a polymethyl methacrylate host. Under the guidance of an analytical effective medium approach, we use the parameter retrieval method to design a well-performed invisible cloak, based on an empirical revised version of the reduced cloak. The cloak is numerically ...

The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO2 in the gas above the solid surface is less than the decomposition pressure of the CaCO3. As the reaction is endothermic, the conventional process for calcination uses coal firing in rotary kiln with limestone feed to get the desired temperatures. Microwave heating of limestone is proposed ...

Cochlear Implants are implantable devices which bypasses the non-functional inner ear and directly stimulates the hearing nerve with electric currents thus enabling deaf people to experience sound again. Implant electrode array design is limited in electrode count, due to their large size in accordance to scala tympani (ST) with restrictions for deeper insertion in ST thus depriving access to ...

Failure of conventional lead-acid battery is attributed to degradation of solid active mass (PbO2 and PbSO4 ). A number of research efforts are underway worldwide to overcome degradation of active mass to improve the cycle life of lead-acid batteries. Soluble lead-acid flow battery (SLFB) is a new kind of lead-acid flow battery in which products of discharge remain in dissolved state. SLFB ...

Deformable image registration is a form of medical image processing that can provide insights into the development of phenomenon and variation in normal anatomical structure over time. Prior to post-operative pleural photodynamic therapy (PDT), a series of CT scans of lungs will be acquired. During PDT treatment, an infrared navigation system is used to contour the lungs and provide real-time ...

The most commonly used type of resonator is the AT-cut, where the quartz blank is in the form of a thin plate cut at an angle to the optic axis of the crystal. This paper reports the modeling of a quartz oscillator for a resonant frequency analysis based on piezoelectric effects. The proposed oscillator consists of a single quartz disc with two electrodes on the top and bottom surfaces of the ...

The optimisation of dimensions, materials choice of heaters in annealing furnaces are done with COMSOL Multiphysics® in 2D-axisymetry. Heat losses sources are identified and corrective actions can be taken in function of simulation results. A power saving of more than 50% is achieved thanks to simulations.

A numerical model was developed to make spatial and temporal predictions of the water quality for Brewster Lake, located in southwestern Michigan. The model considers the hydrodynamics of the lake, hydrologic conditions, physical, chemical and biochemical processes that take place in the lake, and nutrient loadings from the surrounding watershed. Physical, chemical, and biochemical data ...
