Atomic Scale Mechanisms of Multimode Oxide Growth on Nickel-Chromium Alloy: Direct in Situ Observation of the Initial Oxide Nucleation and Growth
(2021)The initial growth mode of oxide on alloy plays a decisive role in the development of protective oxide scales on metals and alloys, which is critical for their functionality for high temperature applications. However, the ... -
Effect of precipitate coherency on the corrosion-induced hydrogen trapping in 2024 aluminum alloy
(2021)Hydrogen trapping is one of the factors leading to hydrogen embrittlement in heat-treatable high-strength aluminum alloys. The effect of coherency of precipitates on the corrosion-induced hydrogen trapping in aluminum alloy ... -
Enhanced Ultrasonic-Assisted Heterogeneous Fenton Degradation of Organic Pollutants over a New Copper Magnetite (Cu-Fe3O4/Cu/C) Nanohybrid Catalyst
(2020)A copper magnetite nanohybrid catalyst (Cu-Fe3O4/Cu/C), abundant of Schottky interfaces and structural defects, with ultrathin encapsulation of graphitic carbon, was synthesized and tested. The catalyst shows enhanced ... -
Glucose electrooxidation reaction in presence of dopamine and uric acid over ketjenblack carbon supported PdCo electrocatalyst
(2019)Herein, palladium-cobalt supported on ketjenblack (PCKB) electrocatalyst is synthesized and tested i) for the reaction of glucose electrooxidation (GOR) in presence of dopamine and uric acid and ii) for the simultaneous ... -
Halloysite nanotubes noncovalently functionalised with SDS anionic surfactant and PS-b-P4VP block copolymer for their effective dispersion in polystyrene as UV-blocking nanocomposite films
(2017)Asimple and versatilemethod is reported for the noncovalent functionalisation of natural and "green" halloysite nanotubes (HNTs) allowing their effective dispersion in a polystyrene (PS) thermoplastic matrix via solvent ... -
Oxygen reduction and hydrogen oxidation reaction on novel carbon supported PdxIry electrocatalysts
(2018)In the present work Vulcan XC-72 carbon supported Pd, Ir and PdxIry (with x:y atomic ratios of 3:1, 1:1, 1:3) electrocatalysts are thoroughly investigated for the reactions of hydrogen oxidation (HOR) and oxygen reduction ... -
Pt/CN-doped electrocatalysts: Superior electrocatalytic activity for methanol oxidation reaction and mechanistic insight into interfacial enhancement
(2017)Nitrogen-doped ordered mesoporous carbon (NOMC) is studied as the support to synthesize a Pt/CN-doped catalyst for methanol oxidation reaction (MOR). The effects of carbon dimension and metal loading are investigated by ... -
Selective electro-oxidation of dopamine on Co or Fe supported onto N-doped ketjenblack
(2022)Herein, we report the synthesis of Co and Fe supported onto N-doped ketjenblack (Co/KB-N and Fe/KB-N) electrocatalysts via a template-free synthesis method, using EDTA nitrogen precursor and oxidized carbon, and their ... -
Skeletal deformity of scoliosis in gilthead seabreams (Sparus aurata): Association with changes to calcium-phosphor hydroxyapatite salts and collagen fibers
(2019)The development of skeletal deformities in seabream farming affects fish growth, survival, and production costs. Collagen distribution in different fish tissues might be correlated with swimming behavior. This study ... -
Synthesis and characterization of activated 3D graphene via catalytic growth and chemical activation for electrochemical energy storage in supercapacitors
(2019)Activated three-dimensional graphene (3D-AGE) powders with high specific surface area have been successfully prepared by combined strategies of catalytic growth and chemical activation for application in supercapacitors. ... -
Zinc uptake, photosynthetic efficiency and oxidative stress in the seagrass Cymodocea nodosa exposed to ZnO nanoparticles
(2019)We characterized zinc oxide nanoparticles (ZnO NPs) by dynamic light scattering (DLS) measurements, and transmission electron microscopy (TEM), while we evaluated photosystem II (PSII) responses, Zn uptake kinetics, and ...
