The improved Two-Color EGR Probe will be modified to probe two separate cool (transition currently being used) and hot CO2 transitions with significant population at ambient and a high temperature indicative of backflowing residual.
The present invention overcomes many of the limitations of AFM cantilevers by enabling amplification of the detection of forces at the tip over a very wide range of frequencies while at the same time reducing unwanted external effects on cantilever dynamics such as stray elect
This invention is an Atomic Force Microscope (AFM) Fluid Delivery/Electrostatic Spray Cantilever for Liquid Extraction-Based Surface Sampling/Ionization Mass Spectrometry that enables sub-micrometer scale spatial sampling of materials from surfaces with direct transfer of
We conceive a resistively heated probe of appropriate composition with drive electronics suitably configured that can achieved pulsed heating rates of the probe at rates of at least 10^9 deg C/s for thermal desorption of macromolecules intact from surfaces with subsequent
The method of the present invention allows a direct measurement of a temperature gradient between two closely spaced conducting bodies, provided the separation gap is small enough to allow quantum electron tunneling and it is adjustable.
The invention relates to a method for determining the clarity of optically dense, clear, or scattering samples, which include: liquid, colloid, gel, emulsions, viscous and non-viscous, or clear optical components.
The ORNL patented and licensed liquid microjunction surface sapling probe (LMJ-SSP) has limited ability to analyze materials from adsorbant surfaces. Solvent can be lost to the surface surface or analytes moved out from vicinity of probe by solvent flow into surface.
Although temperature measurements on the micro- and nanoscale are greatly challenging, they are vitally important in a large number of technological processes.
Apparatus and method are provided for utilization of an unmanned aerial vehicle (UAV) for aerosol sampling of sundry analytes that may be present in the atmosphere, such as a plume from a vent stack, fire, or chemical or biological release. Apparatus comprises a unique p
The present invention includes a versatile, specially designed electrostatic aerosol sampling device. There are many benefits to the design of this system over conventional electrostatic systems.
