Findings from Lomonosov Moscow State University Yields New Findings on Oxides (Vibrational spectra of carbon dioxide adsorbed on nanopore walls at supermonolayer and submonolayer coverage)

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Oxides are presented in a new report. According to news reporting out of Moscow, Russia, by NewsRx editors, research stated, "Coherent anti-Stokes Raman scattering (CARS) spectroscopy is applied to probe the microstructure of CO2 adsorbed in nanoporous glass Vycor with a mean pore radius of 2 nm. CARS spectra of the Q-branch (1388 cm(-1)) were measured at 22 degrees C at pressures decreasing in a range providing the transition from the condensed phase in the whole volume of the pores to submonolayer coverage on their walls."

Our news journalists obtained a quote from the research from Lomonosov Moscow State University, "The spectral behavior demonstrates sequential changes in the fluid state inside the nanopores. The analysis of the experimental results allowed us to characterize and compare the spectral properties of gas-like, liquid-like, and surface adsorbed carbon dioxide."

According to the news editors, the research concluded: "The results provide clear evidence that as the surface coverage is decreased, the vibrational frequency shifts down."
