Raman spectral analysis of nasopharyngeal carcinoma cell line CNE2 after microwave radiation.

Research RF Safe Research Library Jan 1, 2013

This in vitro study used Raman spectroscopy to assess microwave radiation effects on the CNE2 nasopharyngeal carcinoma cell line across exposure times from 2 to 25 minutes. The authors report detectable spectral changes (including C-H deformation and amide I) and significant PCA differences after 10 minutes of…

Cyanide orientational ordering and copper electric field gradients in CuCN.N2H4.

Research RF Safe Research Library Jan 1, 2009

This study reports solid-state NMR (13C and 15N MAS) measurements on CuCN·N2H4 to extract copper quadrupole coupling constants and characterize cyanide ordering. Ab initio calculations were used to determine electric field gradient and chemical shielding tensor orientations needed for spectral analysis. The authors…

Biological proton pumping in an oscillating electric field.

Research RF Safe Research Library Jan 1, 2009

This paper models biological proton pumping in cytochrome c oxidase under an applied oscillating electric field. The authors report that proton pumping efficiency and steady-state electronic currents vary significantly with the field’s frequency and amplitude. A spectral analysis is described as supporting dominant…
