    摘要： A gated III-V semiconductor structure and a method for fabricating the gated III-V semiconductor structure includes a threshold modifying dopant region within a III-V semiconductor barrier layer at the base of an aperture through a passivation layer that otherwise passivates the III-V semiconductor barrier layer. The passivation layer, which may comprise an aluminum-silicon nitride material, has particular bandgap and permittivity properties that provide for enhanced performance of a III-V semiconductor device that derives from the III-V semiconductor structure absent a field plate. The threshold modifying dopant region provides the possibility for forming both an enhancement mode gated III-V semiconductor structure and a depletion mode III-V semiconductor structure on the same substrate. The threshold modifying dopant region when comprising a magnesium (Mg) threshold modifying dopant may be incorporated into the gates III-V semiconductor structure using a dicyclopentadienyl magnesium (Cp2Mg) vapor diffusion method or a magnesium-silicon nitride (MgSiN) solid state diffusion method.

    摘要： A chemical vapor deposition method for forming an aluminum-silicon nitride layer upon a substrate uses an aluminum precursor, a silicon precursor and a nitrogen precursor under chemical vapor deposition conditions to deposit the aluminum-silicon nitride layer upon the substrate. The aluminum-silicon nitride layer has an index of refraction interposed between silicon nitride and aluminum nitride. The aluminum-silicon nitride layer also has a bandgap from about 4.5 to about 6 eV and a permittivity from about 6×10̂-11 to about 8×10̂-11 F/m. The aluminum-silicon nitride layer may be further thermally annealed to reduce a hydrogen content of the aluminum-silicon nitride layer.

    摘要： A system and method for creating a buffer solution having a desired pH value is disclosed. The method uses two known buffer solutions, each with predetermined pH values, and determines a mathematical relationship which defines the amount of each known buffer solution needed to create the buffer solution with the desired pH. This method can then be used to create one or more denaturation graphs, which demonstrate the stability of a protein at a given pH level.

    摘要： A system for automatically creating a denaturation curve is disclosed. In accordance with certain embodiments, a movement system including a unit having a plurality of cannulas is used. The cannulas are in fluid communication with a fluid system, which allows the cannulas to draw in and dispense fluid. A measurement system is included which draws fluid from a well into a detector to determine a characteristic of the fluid. A controller is used to control these systems and also to create a denaturation graph from the measured characteristics. In another embodiment, a plurality of formulations may be created using the system.

    摘要： A system and method of use is provided for using electrochemical impedance spectroscopy to determine the corrosion rates of coupled metals. Two dissimilar metals are coupled together and exposed to a saltwater electrolyte in an electrochemical cell. A variable frequency current is passed through the cell and collected at the coupled metals. The impedance and phase angle of the collected current data are plotted verses frequency. The plotted data are compared to and analogized to a known plot for physical electric circuits. When a matching plot and circuit are found, the corrosion rate data associated with the matched plot are used to determine the corrosion rates of the coupled metals.

    摘要： A separation apparatus and method are employed using a separation channel for rotation about an axis. Such channel includes radially spaced apart inner and outer side wall portions and an end wall portion. An inlet conveys fluid into the channel. A barrier is located in the channel intermediate of the inner and outer side wall portions. A first flow path communicates between upstream and downstream sides of the barrier. A collection region may be located downstream of the barrier for communication with the first flow path. An outer side wall section of the channel may be positioned radially outward of an upstream section thereof. The barrier may join the outer side wall portion along a substantial portion of an axial length of the channel. First and second exit flow paths may allow communication with the channel either upstream or downstream of the barrier or both.
