Different promoting roles of ruthenium for the oxidation of primary and secondary alcohols on PtRu electrocatalysts
(Elsevier, 2021-06-17)This study shows remarkably different features between the oxidation of secondary and primary C3-C5 alcohols. The oxidation of primary alcohols is controlled by the oxidative removal of blocking adsorbates, such as CO, ... -
Disappearance of Melt Memory Effect with Comonomer Incorporation in Isodimorphic Random Copolyesters
(ACS, 2023-10)Melt memory effects in polymer crystallization have attracted much attention in the past few years. Although progress has been made in understanding how the chemical structure of polymers can affect melt memory, there are ... -
Disentangling Component Dynamics in an All-Polymer Nanocomposite Based on Single-Chain Nanoparticles by Quasielastic Neutron Scattering
(American Chemical Society, 2022-02)[EN] We have investigated an all-polymer nanocomposite (NC) consisting of single-chain nanoparticles (SCNPs) immersed in a matrix of linear chains of their precursors (25/75% composition in weight). The SCNPs were previously ... -
Disentangling Self-Atomic Motions in Polyisobutylene by Molecular Dynamics Simulations
(MDPI, 2021-02-23)We present fully atomistic molecular dynamics simulations on polyisobutylene (PIB) in a wide temperature range above the glass transition. The cell is validated by direct comparison of magnitudes computed from the simulation ... -
Disentangling the Calorimetric Glass-Transition Trace in Polymer/ Oligomer Mixtures from the Modeling of Dielectric Relaxation and the Input of Small-Angle Neutron Scattering
(American Chemical Society, 2022-08)We have disentangled the contributions to the glass transition as observed by differential scanning calorimetry (DSC) on simplified systems of industrial interest consisting of blends of styrene-butadiene rubber (SBR) and ... -
Disentangling the role of electrons and phonons in the photoinduced CO desorption and CO oxidation on (O,CO)-Ru(0001)
(Frontiers Media, 2023-07)The role played by electronic and phononic excitations in the femtosecond laser induced desorption and oxidation of CO coadsorbed with O on Ru(0001) is investigated using ab initio molecular dynamics with electronic friction. ... -
Does phosphorylation increase the binding affinity of aluminum? A computational study on the aluminum interaction with serine and O-phosphoserine
(2018-12-15)Several toxic effects arise from aluminum's presence in living systems, one of these effects is to alter the natural role of enzymes and non-enzyme proteins. Aluminum promotes the hyperphosphorylation of normal proteins. ... -
Dual crosslinking of low-methoxyl pectin by calcium and europium for the simultaneous removal of pharmaceuticals and divalent heavy metals
(Elsevier, 2023-11)The contamination of water resources by heavy metals and pharmaceuticals is a significant threat to human health and the environment. Pectin is a promising material for removing heavy metals from water. However, its removal ... -
Effect of Annealing on the Magnetic Properties of Co2MnSi-Based Heusler Alloy Glass-Coated Microwires
(MDPI, 2023-02-16)In the current study, we concentrated on the influence of annealing on the magnetic behavior of Co2MnSi-based Heusler microwires. We set the annealing temperature at 1023 K for 2 h, as the sample did not show any significant ... -
