Char combustion is one of the most important reactions in the process of Underground Coal Gasification (UCG). Experiments are performed in a boat reactor under near isothermal condition to demonstrate effects of heat and mass transfer and bed diffusion through ash layer. To obtain a ... En savoir plus

The High Flux Isotope Reactor, located at the Oak Ridge National Laboratory, is scheduled to undergo a conversion of the fuel used and this proposed change requires an extensive analysis of the flow through the reactor core. The core consists of approximately 500 very thin and long fuel ... En savoir plus

Seco Tools produces inserts for machining metals. Roughly half the number of inserts Seco Tools produces are coated by Chemical Vapour Deposition (CVD) which extends the inserts lifetime in machining operations significantly. More than 10 000 inserts are coated on trays in each CVD run. ... En savoir plus

The high temperature measurement of thermal conductivity is vital for predicting nuclear fuel performance both during reactor operation and accident conditions. The proposed method uses experimental thermograms obtained via high temperature laser-flash heating of a disc-shaped sample in ... En savoir plus

Existing commercial pyrolysis systems do not have the capability to perform millisecond-scale temporal analysis of pyrolysis vapors that can provide time-resolved experimental data on the reactive and stable gas-phase intermediates predicted by models based on Density Functional Theory ...

The vacuum arc remelting is a refining process used to melt reactive metals like titanium, zirconium or hafnium. Melting is performed under vacuum to avoid reactions between liquid metal and oxygen which could be a source of pollution. This process is particularly well suited to purify ... En savoir plus

System for in-situ control of the ion angular distribution function (IADF) in plasma reactor is modeled. Typical IADF depends on the pressure, bias and excitation frequency. It is formed due to a difference in the physical properties of the plasma and sheath domains. The IADF is modified ... En savoir plus

Thrombosis is the formation of a thrombus or blood clot within a vessel to maintain the integrity of the circulatory system [1]. The process involves surface interactions, with coagulation leading to the formation of thrombin and a fibrin network, and platelet aggregation [2]. ... En savoir plus

Microalgae can be directly used in health food or as biofilters for waste water treatment. They also have numerous commercial applications in cosmetics, aquaculture and chemical industry as a source of highly valuable molecules, e.g., polyunsaturated fatty acids, and they are ... En savoir plus

Recently, the advanced plasma tools have been using very high frequency power sources (>100 MHz) and their combination to excite plasma utilized in semiconductor technology. This approach is evoking the regimes that are less understood and currently a subject to many studies and ... En savoir plus
