Interaction of Fullerenes with Organosilanes in the Ionization Chamber of a Mass Spectrometer under Electron Impact and the Reaction of C60 with Tetraphenylsilane in Solution under UV Irradiation

Journal of Spectroscopy, 2016
C60 was shown to react with organosilanes Me4Si, Ph2SiH2, Ph2MeSiH, Ph4Si, and α-naphthylphenylmethylsilane in the electron ionization ion source of a mass spectrometer with the transfer of the corresponding organic radicals (Me, Ph, and α-naphthyl) from

Serines 440 and 467 in the Werner syndrome protein are phosphorylated by DNA-PK and affects its dynamics in response to DNA double strand breaks

Aging, 2014
WRN protein, defective in Werner syndrome (WS), a human segmental progeria, is a target of serine/threonine kinases involved in sensing DNA damage. DNA-PK phosphorylates WRN in response to DNA double strand breaks (DSBs).

Modeling of diffuse reflectance for a two layered medium: A Monte-Carlo study

Results in Optics
A simple exponential model of diffuse reflectance for a two-layered medium was developed theoretically based on Monte Carlo simulation. Absorption and reduced scattering coefficients of these two layers were chosen to be different in which scattering ...
