water/ zeolite single crystalsRaman spectroscopywater tracer diffusionThe water tracer diffusion in single crystals of natrolite, scolecite, mesolite, heulandite, and chabazite has been studied by Raman micro-spectroscopy. A model of water tracer diffusion is proposed. The H 2 O, HDO, and D 2...
and the microscopic origin of this behaviour is believed to be ion-induced perturbation of water’s hydrogen-bonding network. Here we provide microscopic insights into this process by monitoring the dissipation of energy in salt solutions using time-resolved terahertz–Raman spectroscopy. We resonantly...
The combination of Raman spectroscopy with ProUmid sorption test systems provides a powerful instrument for investigating moisture-induced structural changes in materials, such as the formation hydrates, polymorphic structures or the crystallization of a
Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon inelastic scattering of monochromatic light. Because different chemical functional groups scatter light at different frequencies, Raman spectroscopy can be used as a tool...
Raman spectroscopyRaman spectroscopy was used for rapid in-situ measurement of alcohols in ethanol-methanol-water ternary systems. Mass fractions of the individual components were determined using calibration curves for binary systems of ethanol-water, methanol-water, and ethanol-methanol. Calibration ...
used Raman spectroscopy to assess brain edema, by measuring the water concentration in the tissue directly.118 Karabeber et al. evaluated the ability of a handheld Raman scanner, guided by surface-enhanced Raman scattering (SERS) nanoparticles, to identify the microscopic tumor extent in a mouse ...
Raman spectroscopy This characterization is carried out to study the vibrational features of MXenes, and can be used to identify the type of bonding in the material. Raman spectroscopy is the choice of scientists over the IR spectroscopy in the MXene study; due to the fact that water in laye...
Low-frequency Raman spectra of ethanol−water binary solutions with varying mixing ratios are measured and presented in the form of the intrinsic Raman scattering activity, the R(ν̄) spectra. They exhibit an isosbestic point at 135 cm-1 between the pure water O−O stretching peak at 185...
Raman spectroscopy has been reported to provide an information-rich and unique fingerprint from biomolecules in cells.33 Raman spectroscopy is also an ideal choice to detect the cell environment at the molecular level and is unaffected by factors such as oxygen, temperature and water. Furthermore, ...
