This idea expands our current surface sampling probe portfolio, providing additional capabilities not before possible for spot sampling and chemical imaging. We have developed a platform for surface spot sampling using laser assisted sample transfer to solution.
Helium-3 is now so scarce as to be practically unavailable. Boron-10 is a well-known neutron converter isotope with energetic charged daughter particles. All known boron gaseous boron compounds are highly toxic and thus considered unsuitable for widespread deployment.
This invention is a new method for the detection of molecules on a surface at a distance. It combines ultraviolet (UV) and infrared (IR) spectroscopic techniques using standoff detection. A surface is scanned with a tunable IR source.
This invention is a means to sample from a surface for subsequent analysis using the ORNL patented liquid microjunction surface sampling probe used with electrospray ionization, atmospheric pressure chemical ionization or other liquid introduction ionization source for
A method for image reconstruction of moving radionuclide distributions.
The human body liberates over 400 chemicals as we revert back to the dust from whence we came. These volatile organic compounds, amino acids, inorganic constituents, and noxious gases are released from a decaying body at specific time points and in specific ratios.
Here, we describe the production and use of uniform silicon nanopost arrays made by nanolithography. These nanopost arrays (NAPA) provide improved ion yields with switching or modulation capabilities for detecting sample adsorbates by mass spectrometry.
The invention allows for the physical/mechanical, and chemical, nanoscale features of various material samples to be measured. The invention provides nanoscale surface as well as subsurface information.
We are proposing a method for quantitative mapping of thermomechanical properties and phase transition temperatures in materials (e.g. polymeric materials) on the nanometer scale, including methodology for creating and controlling reproducible mechanical contact area.
This invention relates to a novel method of enhancement for photo detecting devices by means of an acoustic resonator. Photo detecting devices (PDDs) are defined as any radiant electromagnetic detecting apparatus.
