On a nonlinear inverse problem in viscoelasticity

open access: yesVietnam Journal of Mechanics, 2009
We consider an inverse problem for determining an inhomogeneity in a viscoelastic body of the Zener type, using Cauchy boundary data, under cyclic loads at low frequency.

The cost of raising quantifiers

open access: yesGlossa, 2018
The main proposal of this paper is that quantifier raising (QR) is not subject to QR-specific locality or domain restrictions but that differences observed between overt and covert movement are the result of an increased processing burden associated with

Electrochemical and Phase Analysis of Si(IV) on Fe Electrode in Molten NaCl-NaF-KCl-SiO2 System

open access: yesHigh Temperature Materials and Processes, 2018
The electrochemical behaviour of Si(IV) ions on Fe electrode in the NaCl-NaF-KCl-SiO2 molten salt system (0.177 mol·L−1 SiO2) at 1,103 K was studied by using cyclic voltammetry, square wave voltammetry, chronoamperometry, and chronopotentiometry ...

Hydrogen Bonding and Proton Transfer Processes during the Electrochemical Reduction of Nitrosobenzene in Acetonitrile

open access: yesChemElectroChem
Nitrosobenzene (PhNO) is the central intermediary during the electrochemical reduction of nitrobenzene in the presence of strong and moderately strong proton donors. Its reduction affords phenylhydroxylamine (PhNHOH) as product through a global mechanism

Effective One-Component Organocatalysts for Eco-Friendly Production of Cyclic Carbonates

open access: yesReactions
One-component or bifunctional organocatalysts are some of the most capable compounds to perform the synthesis of cyclic carbonates from epoxides and carbon dioxide (CO2) since the presence of a co-catalyst is not required.
