UV characterization and photodegradation mechanism of the fungicide chlorothalonil in the presence and absence of oxygen
(Pergamon-Elsevier Science Ltd, 2017-09)
An experimental and theoretical study of the UV spectrum of CT was carried out and the vibrationally resolved HOMO→LUMO transition is presented for the first time. The fluorescence spectrum has also been recorded. Furthermore, ...
Understanding the role played by protic ionic liquids (PILs) and the substituent effect for enhancing the generation of Z -cinnamic acid derivatives
(Royal Society of Chemistry, 2020-04)
Photoisomerization of a series of substituted E-cinnamic acids in MeCN in their acid forms and as their corresponding protic ionic liquids (PILs) with light of 300 nm is studied. The nature, strength, number, and position ...
Soft-gluon resummation for high-pT inclusive-hadron production at COMPASS
(American Physical Society, 2013-07-01)
We study the cross section for the photoproduction reaction N ! hX in fixed-target scattering at COMPASS, where the hadron h is produced at large transverse momentum. We investigate the role played by higher-order QCD ...
Photochemical Behavior of Some Estrone Aryl and Methyl Sulfonates in Solution: Preparative and Mechanistic Studies
(Wiley Blackwell Publishing, Inc, 2021-01)
Direct irradiation of estrone aryl and methyl sulfonates in different organic solvents under nitrogen atmosphere was investigated under steady-state conditions. The estrone derivatives reacted efficiently through the ...
Intra- and extracellular DNA damage by harmine and 9-methyl-harmine
(Elsevier Science Sa, 2014-02-13)
It is known that b-carbolines are able to produce photosensitized damage in cell-free DNA, but there is little information on their effects on cellular DNA. Therefore, we have analyzed the DNA damage produced by harmine ...
Towards an insight on photodamage in hair fibre by UV-light: An experimental and theoretical study
(2013-06-27)
Synopsis: Objectives: In this research, an experimental and theoretical study was conducted to design a photodegradation mechanism of the amino acid tryptophan (Trp) in hair fibres. Methods: For the experimental research, ...
gamma p and gamma gamma scattering from (p)over-bar-p, pp forward amplitudes in a QCD eikonal model with a dynamical gluon mass
(American Physical Soc, 2006-04-01)
We examine the gamma p photoproduction and the hadronic gamma gamma total cross sections by means of a QCD eikonal model with a dynamical infrared mass scale. In this model, where the dynamical gluon mass is the natural ...
eta ->gamma gamma decay width via the Primakoff cross section
(Amer Physical Soc, 2008-07-04)
Incoherent eta photoproduction in nuclei is evaluated at forward angles within 4 to 9 GeV using a multiple scattering Monte Carlo cascade calculation with full eta-nucleus final-state interactions. The Primakoff, nuclear ...
Correlations between theoretical calculations and experimental photochemical reactivity of hydroxyanthraquinone drugs present in Aloe vera
