Vibrational spectra and surface-enhanced vibrational spectra of 1-nitropyrene
(2004)
The present report on the vibrational spectra of 1-nitropyrene (1-NP) describes the infrared and Raman spectra; their interpretation is aided by local density functional theory (DFT) calculations at the B3LYP/6-311G(d,p) ...
Pulsating Flow of an Ostwald-De Waele Fluid between Parallel Plates
(MDPI, 2020)
The flow between two parallel plates driven by a pulsatile pressure gradient was studied analytically with a second-order velocity expansion. The resulting velocity distribution was compared with a numerical solution of ...
Surface enhanced raman scattering of trans-p-coumaric and syringic acids
(2009)
The vibrational spectra of trans-p-coumaric acid (pCA) and syringic acid (SA) are discussed. The spectral fingerprints of the organic acids observed in the infrared and Raman spectra are assigned to fundamental vibrational ...
Plasmon-enhanced fluorescence spectroscopy
(Royal Society Chemistry, 2017)
Fluorescence spectroscopy with strong emitters is a remarkable tool with ultra-high sensitivity for detection and imaging down to the single-molecule level. Plasmon-enhanced fluorescence (PEF) not only offers enhanced ...
Multiresolution Speech Enhancement Based on Proposed Circular Nested Microphone Array in Combination with Sub-Band Affine Projection Algorithm
(MDPI, 2020)
Speech enhancement is one of the most important fields in audio and speech signal processing. The speech enhancement methods are divided into the single and multi-channel algorithms. The multi-channel methods increase the ...
Fluorescence and surface-enhanced vibrational spectroscopies of lawsone and plumbagin
(Taylor and Francis Inc., 2016)
© 2016, Copyright © Taylor & Francis Group, LLC. The natural dyes lawsone and plumbagin (1,4-naphthoquinones) were studied by using fluorescence, Raman, infrared (IR), surface-enhanced Raman scattering (SERS), and ...
On the spectral dependency of UV radiation enhancements due to clouds in Valdivia, Chile (39.8 degrees S)
(AMER GEOPHYSICAL UNION, 2005-07-27)
Data gathered with a five-channel radiometer are used to analyze the spectral composition of cloud enhancements and attenuations of UV (305, 320, 340, and 380 nm) and photosynthetically active radiation (PAR) (400-700 nm) ...
Heat transfer enhancement strategies in a swirl flow minichannel heat sink based on hydrodynamic receptivity
(Elsevier Ltd, 2018)
The swirl flow minichannel heat sink has shown to be a promising alternative for thermal management of
high heat flux applications, such as electronics and concentrated photovoltaics. Effective heat transfer
enhancement ...
Optimization of sample treatment for the identification of anthraquinone dyes by surface-enhanced Raman spectroscopy
(Springer Verlag, 2017)
© 2017, Springer-Verlag Berlin Heidelberg. The study and characterization of old artifacts such as pigments requires the use of techniques that need a small amount of sample to perform the analysis because of the high value ...
