The goal of this review is to discuss post-irradiation analysis of low-energy (?50 eV) electron-induced processes in nanoscale thin films. Because electron-induced surface reactions in monolayer adsorbates have been extensively reviewed, we will instead focus on low-energy electron-induced reactions in multilayer adsorbates. The latter studies, involving nanoscale thin films, serve to elucidate the pivotal role that the low-energy electron-induced reactions play in high-energy radiation-induced chemical reactions in condensed matter. Although electron-stimulated desorption (ESD) experiments conducted during irradiation have yielded vital information relevant to primary or initial electron-induced processes, we wish to demonstrate in this review that analyzing the products following low-energy electron irradiation can provide new insights into radiation chemistry. This review presents studies of electron-induced reactions in nanoscale films of molecular species such as oxygen, nitrogen trifluoride, water, alkanes, alcohols, aldehydes, ketones, carboxylic acids, nitriles, halocarbons, alkane and phenyl thiols, thiophenes, ferrocene, amino acids, nucleotides, and DNA using post-irradiation techniques such as temperature-programmed desorption (TPD), reflection-absorption infrared spectroscopy (RAIRS), X-ray photoelectron spectroscopy (XPS), high-resolution electron energy loss spectroscopy (HREELS), gel electrophoresis, and microarray fluorescence. Post-irradiation temperature-programmed desorption, in particular, has been shown to be useful in identifying labile radiolysis products as demonstrated by the first identification of methoxymethanol as a reaction product of methanol radiolysis. Results of post-irradiation studies have been used not only to identify radiolysis products, but also to determine the dynamics of electron-induced reactions. For example, studies of the radiolysis yield as a function of incident electron energy have shown that dissociative electron attachment plays an important role in the electron-induced single strand breaks in DNA leading to mutagenic damage. Studies such as these not only provide insight into the fundamentals of electron-molecule interactions in the condensed phase but also may provide information valuable to (a) furthering cost-efficient destruction of hazardous chemicals, (b) understanding the electron-induced decomposition of feed gases used in the plasma processing of semiconductor devices, (c) clarifying the role, if any, of low-energy electrons, produced by cosmic rays, contributing to the formation of the ozone hole by interacting with halocarbons and producing Cl atoms, (d) illuminating the dynamics of electron-induced oligomerization and/or polymerization, and (e) explicating the astrochemistry of icy grains.

453-20-3, Name is 3-Hydroxytetrahydrofuran, belongs to tetrahydrofurans compound, is a common compound. Application In Synthesis of 3-HydroxytetrahydrofuranIn an article, once mentioned the new application about 453-20-3.

This work outlines the preparation and characterization of a novel bio-based epoxy resin derived from tannic acid (TA). The TA-based epoxy resin (ETA) was firstly synthesized via glycidylation by epichlorohydrin, and then spectrally characterized by FTIR. The thermal properties of the bio-resin were evaluated by DSC, TGA and OIT analyses. The curing kinetic parameters calculated by the Vyazovkin’s advanced isoconversional method showed that ETA had a different activation energy dependency on conversion compared with the conventional petroleum-based epoxy resin, i.e., diglycidylether bisphenol A, Epikote 828. The bio-resin exhibited good thermal stability and higher char yield comparing to the petro-based one. Pyrolysis-GC/MS was used to evaluate the thermal degradation products of the bio-resin. The biocompatibility properties evaluated by L929 fibroblast cells viability revealed no cytotoxicity. ETA was also found to be an effective antioxidant material. The research promised new generation of epoxy thermosets comprising natural based phenolic compounds without toxic bisphenol A, which could be used in biomaterials, electrical circuit boards, or inherent antioxidants.

Chirality transfer from circular dichroism (CD)-silent secondary alcohol (inductor) to the stereodynamic bichromophoric di(1-naphthyl)methane probe (reporter) led to the generation of intense, induced exciton-type Cotton effects (CEs) in the ultraviolet-visible absorption region. The di(1-naphthyl)methane probe exhibits extraordinarily high sensitivity to even small structural variations of the alcohol skeleton, that is, the probe is able to distinguish between an oxygen atom and a methylene group in a 3-hydroxytetrahydrofurane skeleton. Signs and amplitudes of the exciton couplets of 1Bb electronic transition might be correlated with the type of stereo-differentiating parts of the molecule flanking the stereogenic center, however, not with the absolute configuration. The origin of the induced CEs was established by means of experimental and theoretical methods. As a result, a mechanism of chirality transfer from the permanent stereogenic center to the bichromophore is proposed.
