It is well known that the visual colour of organic compounds results from absorption of light in the 350 to 750 nm region. Although the spectral response of the human eye is involved in color perception, the measurement of the spectral absorption feature in the ultraviolet (UV) and visible (...
spectroscopy(ATR-FTIR)spectra indicate that the UV-irradiated part of the nylon6fabric surface was photo- oxidized.After the UV irradiation,the nylon6fabric became yellow,and the whiteness decreased.Owing to the fracture of the amide group(−CONH−),the amorphous region of the fiber increased...
Machine learning (ML) algorithms were explored for the classification of the UV–Vis absorption spectrum of organic molecules based on molecular descriptors and fingerprints generated from 2D chemical structures. Training and test data (~ 75 k mo

The chemical compositions of the glass surfaces were detected by X-ray photoelectron spectroscopy (XPS, ESCALAB 250, Thermo Fisher Scientific) with Al Kα radiation source under a pressure of 2 × 10−9 mbar. The water contact angles (WCAs) on the bare and modified glass slides were measur...
Understanding energy storage mechanisms in electrochemical energy storage devices lays the foundations for improving their energy and power density. Here we introduce in situ ultraviolet–visible (UV–Vis) spectroscopy method to distinguish battery-type,
The reaction products in scrubbed solution were characterized by ion chromatography (ICs) and high-performance liquid chromatography (HPLC), while free radicals generated in the reaction process was analyzed by electron spin resonance (ESR) spectroscopy. The results showed that the reaction products in...
Fe(III) complex of 2-phenylbenzimidazole has been covalently anchored on polymer and characterized by elemental analysis, FT-IR, far-IR, BET surface area measurements, UV–Vis/DRS spectroscopy, thermo-gravimetric analysis and magnetic moment measurements by VSM which confirmed an octahedral environment...
