Influence of the N atom and its position on electron photodetachment of deprotonated indole and azaindole
(Royal Society of Chemistry, 2020-12)
Electron photodetachment of cold deprotonated indole and azaindole anions has been studied by use of a mass-selective photofragmentation spectrometer capable of negative ion and neutral particle detection. The electron ...
Ubiquitous deprotonation of terephthalic acid in the self-assembled phases on Cu(100)
(Royal Society of Chemistry, 2018-06-09)
We performed an exhaustive study of terephthalic acid (TPA) self-assembly on a Cu(100) surface, where first-layer molecules display two sequential phase transitions in the 200-400 K temperature range, corresponding to ...
Adiabatic deprotonation as an important competing pathway to ESIPT in photoacidic 2-phenylphenols
(Royal Society of Chemistry, 2019-05)
ESIPT (Excited State Intramolecular Proton Transfer) to C atom in 2-phenylphenol is known to be an intrinsically inefficient process. However, to the best of our knowledge, a structure-ESIPT efficiency relationship has not ...
An exploratory conformational analysis of 3-mercapto-propanamide and 2-methyl-3-mercapto-propanamide as well as their S-deprotonated conjugate basis: An ab initio study
(Elsevier Science, 2000-08-25)
Ab initio conformational analysis has been carried out on 3-mercapto-propanamide, (R)- and (S)-2-methyl-3-mercaptopropanamide as well as their S-deprotonated conjugate basis. They were carried out at the HF/3-21G level of ...
Chitosan and crosslinked chitosan nanoparticles: Synthesis, characterization and their role as Pickering emulsifiers
(2020-12-15)
Chitosan has been modified in order to produce nanoparticles with promising characteristics in diverse food applications, e.g. Pickering emulsions. Chitosan deprotonation and ionic crosslinking with tripolyphosphate were ...
NaOH treatment of Chitosan films: impact on macromolecular structure and film properties
(Elsevier, 2015-05)
In this paper, we examine the significance of treatment with NaOH on chitosan (CH) film structure toobtain biodegradable materials for several applications. In order to determine the structure of the films,an analysis based ...
