The present invention provides an emissivity independent optical pyrometry technique and apparatus that allows absolute measurements of surface temperature using a non-contact probe. The technique allows surface temperatures between 300 Deg. C and 1400 Deg.
A high-temperature reactor for Diffuse Reflectance Infrared Fourier-Transform Spectroscopy (DRIFTS) is described that allows the observation of both surface and gas-phase analysis under realistic operating conditions.
Tip-Enhanced Laser desorption (LD) or ablation (LA) in transmission or reflective geometry, at an acute, right or obtuse angle, directly into a liquid junction at the surface of interest that is formed between a solvent dispensing and retrieving AFM probe and the surface.
Measurement of volatile particles emitted by modern jet engines is a daunting task.
Laser desorption (LD) or ablation (LA) in transmission or reflective geometry, at an acute, right or obtuse angle, directly into a liquid junction at the surface of interest that is formed between a solvent dispensing and retrieving unit and the surface. These processes
The invention is directed towards the use of small diameter anodes such as carbon fibers, carbon nanotubes, and nanostructured Si wafers which are useful as anodes in radiation detection devices such as proportional radiation counters (PCs).
Preparation of dried sample spots on planar media is becoming a popular sample storage, preparation, shipping and analysis medium.
Dispersion of particulate material in a liquid media can be enhanced by application of sonic or ultrasonic energy. Application of acoustic energy can be accomplished by several transduction means such as piezoelectric, magnetostrictive, and electromagnetic.
The extreme sensitivity of SERS is dominated by the electromagnetic enhancement, referring to the intense, spatially varying E fields produced by plasmonic coupling between closely spaced metal nanoparticles.
The subject invention is an advanced chlorophyll pulse amplitude modulation fluorometer for environmental monitoring. Detection is achieved by algal biosensors that grow naturally in source drinking waters. The principle of detection is chlorophyll fluorescence measurement.
