Submicron particles collected on Teflon filters aboard the R/V Ronald Brown during the Texas Air Quality Study and Gulf of Mexico Atmospheric Composition and Climate Study (TexAQS/GoMACCS) 2006 in and around the port of Houston, Texas, were measured by Fou ...
Plasma diagnostics for large area, industrial RF parallel-plate reactors can be useful for process optimization and monitoring, provided that their implementation is practical and non-intrusive. For instance, Fourier transform infrared (FTIR) absorption sp ...
We report here a new technique for spectroscopic studies of protonated, gas- phase biomolecules and demonstrate its utility by measuring highly-resolved electronic and infrared spectra of peptides of up to 17 amino acids. After UV excitation of an aromatic ...
Infrared absorption spectroscopy enabling direct access to vibrational fingerprints of the molecular structure is a powerful method for functional studies of bio-molecules. Although the intrinsic absorption cross-sections of IR active modes of proteins are ...
A novel metal-free "black dye" was designed and synthesized for panchromatic dye-sensitized solar cells. Based on this dye, the broader incident photon-to-current conversion efficiency spectrum was obtained over the whole visible range extending into the n ...
The rotational spectrum of cyanic acid, HOCN, has been detected in the centimeter-wave band in a molecular beam by Fourier transform microwave spectroscopy and in the millimeter-wave band by conventional spectroscopy in a low-pressure laboratory discharge. ...
Some layers of thin film photovoltaic modules maybe critically sensitive to moisture. In this study we present a new tool for monitoring the effect of moisture using a particular Transparent Conductive Oxide (TCO) as a sensor. The moisture content of the e ...
Single particles were collected from an aircraft platform as part of the Intercontinental Chemical Transport Experiment - Phase B (INTEX-B) conducted over the eastern Pacific and western North America. Single particle spectra were obtained using scanning t ...
Products of thermal dehydrogenation of C60H18 (which mainly occurs at 450-600 degrees C) were studied by XRD, Raman, IR and mass spectrometry. IR spectra indicate that dehydrogenation resulted in partial recovery of pristine C-60. XRD data indicate that th ...
We perform broadband microwave absorption spectroscopy and explore the switching behavior of 300-nm-wide and 20-nm-thick Ni80Fe20 nanowires under irradiation of a magnetic rf field. In particular, we investigate two arrays where the nanowires exhibit a dif ...
