Analysis of the torsion-rotation spectra of the isotopic methanol molecules
(Elsevier, 1972-08)
The high resolution infrared spectra of CH3OH, CH3OD, CD3OH and CD3OD observed by D. R. Woods and C. W. Peters in the region from 400 to 900 cm-1 have been analyzed to obtain the molecular moments of inertia, the barrier ...
Measurement of fracture stress, young's modulus, and intrinsic stress of heavily boron-doped silicon microstructures
(Elsevier, 1989-12-10)
Heavily boron-doped silicon microstructures fabricated using deep-boron diffusions and boron etch-stops have been widely used in a variety of integrated sensors and actuators. For many applications, having knowledge of the ...
Biochemical sensors based on polymer microrings with sharp asymmetrical resonance
(The American Institute of Physics, 2003-08-25)
Photonic microresonators have great potential in the application of highly sensitive sensors due to high Q-factor resonances and steep slopes between zero and unity transmission. A microring resonator with increased resonance ...
Nanoscale thermal transport
(The American Institute of Physics, 2003-01-15)
Rapid progress in the synthesis and processing of materials with structure on nanometer length scales has created a demand for greater scientific understanding of thermal transport in nanoscale devices, individual ...
Nature and distribution of electrically active defects in Si‐implanted and lamp‐annealed GaAs
(The American Institute of Physics, 1985-12-01)
The nature and spatial distribution of deep levels arising from defects in device‐quality, Si‐implanted, and lamp‐annealed liquid encapsulated Czochralski GaAs have been investigated. The best activation and mobility values ...
A model of flow and surfactant transport in an oscillatory alveolus partially filled with liquid
(The American Institute of Physics, 2005-03)
The flow and transport in an alveolus are of fundamental importance to partial liquid ventilation, surfactant transport, pulmonary drug administration, cell-cell signaling pathways, and gene therapy. We model the system ...
Monte Carlo studies on the well‐width dependence of carrier capture time in graded‐index separate confinement heterostructure quantum well laser structures
(The American Institute of Physics, 1993-10-04)
The total carrier capture time and the quantum well width are both important parameters affecting the graded‐index separate confinement heterostructure (GRINSCH) quantum well laser modulation speed limit. However, discrepancies ...
A Morphology-Cosmology Connection for X-Ray-Clusters
(Univ Chicago Press, 1993-12-10)
We employ N-body/three-dimensional gasdynamic simulations of the formation of galaxy clusters to determine whether cluster X-ray morpholgies can be used as cosmological constraints. Confirming the analytic expectations of ...
Localization of parathyroid enlargement: experience with technetium-99m methoxyisobutylisonitrile and thallium-201 scintigraphy, ultrasonography and computed tomography
(Springer-Verlag, 1994-01)
Technetium-99m methoxyisobutylisonitrile (MIBI), like thallium-201, has recently been introduced as a myocardial perfusion agent and is now also showing very promising results in parathyroid scintigrapy. The results of 201 ...
Magnetically modulated optical nanoprobes
(The American Institute of Physics, 2003-02-17)
We have developed magnetically modulated optical nanoprobes (MagMOONs) to magnetically modulate the signal from fluorescent probes and thus separate it from autofluorescence, electronic offsets, and other background signals. ...
