Creator:: Hecker, Christoph, Dilles, John H., van der Meijde, Mark, and van der Meer, Freek D.
Abstract:: In this paper, we present an approach to extracting mineralogic information from thermal infrared (TIR) spectra that is not based on an input library of pure mineral spectra nor tries to extract spectral end-members from the data. Instead, existing modal mineralogy for a number of samples are used to build...

Tunable thermal switching via DNA-based nano-devices

Creator:: Chien, Chih-Chun, Velizhanin, Kirill A., Dubi, Yonatan, and Zwolak, Michael
Abstract:: DNA has a well-defined structural transition-the denaturation of its double-stranded form into two single strands-that strongly affects its thermal transport properties. We show that, according to a widely implemented model for DNA denaturation, one can engineer DNA 'heattronic' devices that have a rapidly increasing thermal conductance over a narrow temperature...

Simulation of thermal hydraulic performance of multiple parallel micropin arrays for concentrating solar thermal applications with supercritical carbon dioxide

Creator:: Hyder, Matthew B. and Fronk, Brian M.
Abstract:: Concentrated solar power (CSP) plants have the potential to provide 24 h, renewable electricity. Current CSP systems have high capital and operational costs which makes the levelized cost of electricity uncompetitive with conventional techniques. Recent experimental research has shown the potential of small unit cells (up to 2 × 2 cm) containing micropin arrays...
