A computer controlled microwave exposure system and specialized applicators were constructed for the purpose of facilitating accurate observations of microwave radiation effects on uninfected and infected biological tissue in vitro and in vivo under different electromagnetic modalities and exposure configuration. To address diverse requirements, three different applicators were developed: a ...

The ubiquitous commercial use of Lithium-Ion batteries (LIBs) has increased interest in their implementation into efficient energy storage systems for clean and renewable power sources and the electrical transportation industry. Unfortunately, LIBs are not yet technological mature to meet various commercial demands. Consider the following challenges for example,: (1) lower than desired effective ...

Predictive food microbiology currently first requires experimental data for growth on fresh produce and then fitting an empirical or semi-empirical model to the data, making extrapolation to other conditions (temperature, type of produce) difficult. Herein, we develop a mechanistic model for the growth of human pathogenic bacteria (Escherichia coli O157:H7 and Salmonella spp.) on spinach using ...

Oil and water are immiscible fluids and they tend to separate very easily when introduced into a flow stream from two different sources in a flow loop. This model studies the development of mixture volume fraction in an oil-water-flow loop with 3 different passive mixing schemes: (i) blind-T, (ii) check valve, and (iii) static mixer. Each device produces different levels of mixture homogeneity ...

Metal foams are interesting materials with many potential applications. They are characterized by a cellular structure represented by a metal or metal alloy and gas voids inside (Fig.1). A common metallic cellular material is aluminum foam which can be produced metallurgically by heating a precursor, made of aluminum alloy and TiH2 as foaming agent, in a furnace. In this case, the foaming process ...
Application of a Weakly Non-Linear Analysis to the Analysis of Thermoacoustic Combustion Instabilities

The thermoacoustic combustion instabilities are complex phenomena that may occur in steady flow combustion systems that are aboard of, e.g., rocket engines or gas turbines. The phenomena involve the interaction of chemical reactions with fluid-dynamic and propagation of pressure waves in the combustion chamber. Combustion instabilities may lead to a stable condition (known as “limit-cycle”) ...

Nuclear Quadrupole Resonance (RQN) is a radio frequency (RF) spectroscopic technique that is used to detect quadrupole nuclei such as Nitrogen-14. NQR was found to be a good candidate for detecting narcotics, explosives and medicines . However, due to its low sensitivity the use of NQR is still limited. One way to increase the sensitivity is to improve the RF coil by means of a better RF ...

In our recent experiments we are revisiting the topografiner technology for the imaging of surface topography with a resolution of a few nanometers. In these new technique called Near-Field Emission Scanning Electron Microscopy (NFESEM), low-energy electrons are emitted from a polycrystalline tungsten tip via electric-field assisted tunneling. In order to characterize and improve the capabilities ...

Novel class of artificial optical antennas are of great interest in biosensing applications of nanoplasmonics due to their unique and tunable spectral properties. Silver colloid spheres covered with L-cysteine were studied experimentally by spectroscopy and TEM and numerically by a COMSOL Multiphysics® simulation. Experimental studies revealed that the Ag NP-Cys core-shell conjugates prefer to ...

The application of super-alloys has grown up in numbers in the industries like aerospace, automotive, nuclear, thermal power plant & medical implants. The initial cost of prototyping and the selection of suitable manufacturing methods & test fixtures made by electrochemical machining (ECM) has proven to be expensive process especially where tolerances are extremely tight on the nanometre scale. ...
