The major results included the following: (i) spectral preprocessing SNV, CR, CWT and 1st SGD reduced the spectral intrasample variability, (ii) the benefit of the

Phenolic acids interactions with clay minerals: A spotlight on the adsorption mechanisms of Gallic Acid onto montmorillonite... Phenolic acids interactions with clay minerals: a

Complex conductivity spectra in the low-frequency range of 0.1 Hz to 45 kHz were successfully described using a triple layer model of the basal surface of Mt

Current complex impedance measurements of charged suspensions are limited at low frequencies (typically<1 kHz) by the electrochemical polarization of the current and po- tential

This behavior strongly differs from previous observations of confinement of nonionic surfactants in clays where the expansion of the interlayer space was limited to two

X-ray diffraction technique has been used to determine the mineralogy of both Na- MMT and Na-SWy2 samples, as well as to quantify the crystalline swelling by measuring the d(001)

Nuclear spin interference effects generated in a macroscopic sample of 10 ml degassed water are de- tected in a simple NMR experiment.. These results are a first step to manipulation
