TL;DR: The mechanism of hydride transfer from the dihydropyridines to acridinium perclorate was diagnosed and elucidated by using the determined thermodynamic parameters and the activation parameters.
Abstract: A series of 45 dihydropyridine-type organic compounds as hydride source were designed and synthesized. The thermodynamic driving forces (defined as enthalpy changes or redox potentials in this work) of the dihydropyridines to release hydride anions, hydrogen atoms (hydrogen for short), and electrons in acetonitrile, the thermodynamic driving forces of the radical cations of the dihydropyridines to release protons and hydrogens in acetonitrile, and the thermodynamic driving forces of the neutral pyridine-type radicals of the dihydropyridines to release electron in acetonitrile were determined by using titration calorimetry and electrochemical methods. The rates and activation parameters of hydride transfer from the dihydropyridines to acridinium perclorate, a well-known hydride acceptor, were determined by using UV−vis absorption spectroscopy technique. The relationship between the thermodynamic driving forces and kinetic rate of the hydride transfer was examined. Thermodynamic characteristic graph (TCG) o...

TL;DR: G-P is more sensitive and selective toward 2,4,6-trinitrophenol (TNP) compared with G-B, and the G-P molecule can not only detect TNP but also remove TNP from the solution into the organogel system.
Abstract: Two simple and novel gelators (G-P with pyridine and G-B with benzene) with different C-4 substitution groups on naphthalimide derivatives have been designed and characterized. Two gelators could form organogels in some solvents or mixed solvents. The self-assembly processes of G-P in a mixed solvent of acetonitrile/H2O (1/1, v/v) and G-B in acetonitrile were studied by means of electron microscopy and spectroscopy. The organogel of G-P in the mixed solvent of acetonitrile/H2O (1/1, v/v) formed an intertwined fiber network, and its emission spectrum had an obvious blue shift compared with that of solution. By contrast, the organogel of G-B in acetonitrile formed a straight fiber, and its emission had an obvious red shift compared with that of solution. G-P and G-B were employed in detecting nitroaromatic compounds because of their electron-rich property. G-P is more sensitive and selective toward 2,4,6-trinitrophenol (TNP) compared with G-B. The sensing mechanisms were investigated by 1H NMR spectroscopic...

TL;DR: In this article, gas evolution and associated pressure build up in supercapacitor devices were monitored using commercial electrode rolls and 1-mol/l solutions of TEABF 4 in acetonitrile (AN), propylene carbonate (PC), and γ-butyrolactone (GBL) during subsequent constant voltage periods (24h) at 25, 275,V, 30,V and 325,V.

TL;DR: In this paper, the degradation of methylene chloride (CH2Cl2) in the presence of O2 at room temperature over films was studied in a stirred batch of O 2 at room-temperature over films.
Abstract: Acetonitrile (CH3CN), methanol (CH3OH), trichloroethylene (C2HCl3, TCE), and methylene chloride (CH2Cl2) were degraded in stirred batch reactors in the presence of O2 at room temperature over films...
