Forming excited chemical species using catalytic generators will convert simple, inexpensive parts or film surfaces such as polyethylene into exotic polymers, perhaps a tenth of a micron thick, which cannot be produced by other means.
The simulation is unprecedented in several aspects--the number of chemical species included, the number of chemical processes modeled and the overall size of the flame.
In the biomedical sector, nanosensors are selectivity used for the detection of biological agents and chemical species.
This innovative CARS analysis will be supported by mass spectroscopy measurements to verify the appearance of corresponding chemical species, and by simulated E field and pore density distributions on the bio-samples.
In addition, this level of scalability for a commercial fluid dynamics solver is unprecedented on our system, especially considering the complexity of the model physics with transient, turbulent flow, chemical species transport and multiple non-reacting flows.
FScan Ltd was set up in 2008 to exploit pioneering discoveries in analysis of a range of biologically active chemical species.
It responds to recent discoveries in a variety of fields that the chemical species of an element (Carbon-13 vs Carbon-14, for instance) determines many factors about its bioavailability and toxicity.
Although the criteria shown in Table 1 and the summary shown in Table 2 are highly subjective, they are selected mainly to provide ways of comparing and ranking the different chemical species.
At that time, ozone depletion was a top priority and the satellite's spectrometer was originally intended to look at all of the chemical species that might be involved in this process.
High resolution XPS spectra allow for the determination of the chemical species present in the specimens.
The orientation of the pole of the rotation axis with respect to the plane of the orbit, creating seasonal effects; the rate of rotation; the percentage of the surface that is active; and the chemical species subliming from the surface are among the many other effects that could play a part.
