Labyrinthine patterns transitions
(American Physical Society, 2020)
Macroscopic systems with injection and dissipation of energy exhibit intricate dissipative structures. Labyrinthine patterns are disordered spatial structures arising into homogeneous media that show a short-range order. ...
Vibrational and surface-enhanced Raman spectra of vanillic acid
(JOHN WILEY & SONS, 2008-09)
The 3-methoxy-4-hydroxybenzoic acid or vanillic acid (VA) is a naturally occurring molecule important in winemaking. The spectral fingerprints of VA observed in the infrared and Raman spectra are assigned to fundamental ...
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 ...
