Quantification of fluctuations from fluorescence correlation spectroscopy experiments in reaction-diffusion systems
(American Physical Society, 2020-11)
Fluorescence correlation spectroscopy (FCS) is commonly used to estimate diffusion and reaction rates. In FCS the fluorescence coming from a small volume is recorded and the autocorrelation function (ACF) of the fluorescence ...
Single-molecule redox blinking of perylene diimide derivatives in water
(American Chemical Society, 2010-03)
Dynamic developments in ultrasensitive and superresolution fluorescence microscopy call for improved fluorescence markers with increased photostability and new functionalities. We used single-molecule spectroscopy to study ...
On the meaning of "collision rate constants" for ion-molecule reactions: Association of hydrogen atoms with C6H5+ and small alkyl radicals with C7H7+ ions
(Elsevier, 2020-12)
Limiting high pressure rate constants for the association of H with C6H5 þ and of CH3, C2H5, and n-C3H7 radicals with C7H7 þ molecular ions are analyzed in terms of “rigidity factors” arising from the anisotropy of the ...
The iso-Nazarov reaction
(Royal Society of Chemistry, 2017-11)
The construction of five-membered rings is essential in organic chemistry. In this context, pentannulation reactions that provide a straightforward access to cyclopentenones are of particular interest, as these structures ...
Mechanisms and product distribution of the O3-initiated degradation of (E)-2-heptenal, (E)-2-octenal and (E)-2-nonenal
(American Chemical Society, 2017-06-16)
The O3-molecule initiated degradation of three 2-alkenals (E)-2-heptenal, (E)-2-octenal, and (E)-2-nonenal has been investigated in a 1080 L quartz-glass environmental chamber at 298 ± 2 K and atmospheric pressure of ...
Synthesis, antiviral and cytotoxic activity of novel terpenyl hybrid molecules prepared by click chemistry
(Molecular Diversity Preservation International, 2018-06)
Naturally occurring terpenes were combined by click reactions to generate sixteen hybrid molecules. The diterpene imbricatolic acid (IA) containing an azide group was used as starting compound for the synthesis of all the ...
Hydrogenated polycyclic aromatic hydrocarbons (H n PAHs) as catalysts for hydrogenation reactions in the interstellar medium: a quantum chemical model
(Royal Society of Chemistry, 2019-05)
The sticking of H atoms onto dust grains and large hydrocarbon molecules has received considerable attention because it is thought to govern the formation of H2 and other H-containing molecules in the interstellar medium. ...
Hybrid Molecules Containing a 7-Chloro-4-aminoquinoline Nucleus and a Substituted 2-Pyrazoline with Antiproliferative and Antifungal Activity
(Molecular Diversity Preservation International, 2016-08)
Twenty-four new hybrid analogues (15-38) containing 7-chloro-4-aminoquinoline and 2-pyrazoline N-heterocyclic fragments were synthesized. Twelve of the new compounds were evaluated against 58 human cancer cell lines by the ...
Covalent Anchoring and Interfacial Reactions of Adsorbed Porphyrins on Rutile TiO2(110)
(American Chemical Society, 2018-03)
Adsorption of 5-monocarboxyphenyl-10,15,20-triphenylporphyrin (MCTPP) to rutile TiO2(110) at room temperature produces molecules on the surface covalently anchored through the carboxylate group, coadsorbed with hydroxyl ...
Role of the recombination channel in the reaction between the HO and HO2 radicals
(American Chemical Society, 2017-01)
The kinetics of the gas phase recombination reaction HO + HO2 + He ⇒ HOOOH + He has been studied between 200 and 600 K by using the SACM/CT model and the unimolecular rate theory. The molecular properties of HOOOH were ...
