Mechanistic insight into electrocatalytic glyoxal reduction on copper and its relation to CO2 reduction
(Royal Society of Chemistry, 2022)
Copper electrodes produce several industrially relevant chemicals and fuels during the electrochemical CO2 reduction reaction (CO2RR). Knowledge about the reaction pathways can help tune the reaction selectivity toward ...
Sustainable PHBH–Alumina Nanowire Nanocomposites: Properties and Life Cycle Assessment
(MDPI, 2022-11-20)
Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) is a bio-based polyester with the potential to replace some common polymers of fossil origin. However, PHBH presents serious limitations, such as low stiffness, tendency ...
A trade-off between ligand and strain effects optimizes the oxygen reduction activity of Pt alloys
(RSC, 2022-10-20)
To optimize the performance of catalytic materials, it is paramount to elucidate the dependence of the chemical reactivity on the atomic arrangement of the catalyst surface. Therefore, identifying the nature of the active ...
Enhanced Charge Transfer Kinetics for the Electroreduction of Carbon Dioxide on Silver Electrodes Functionalized with Cationic Surfactants
(Wiley, 2022-12-09)
Cationic ammonium surfactants can be used together with a suitable catalyst to enhance the electroreduction of carbon dioxide (CO2RR). However, the underlying reasons for the improvements are not yet well understood. In ...
Fabrication and Magneto-Structural Properties of Co2-Based Heusler Alloy Glass-Coated Microwires with High Curie Temperature
(MDPI, 2022)
[EN] In this work, we were able to produce Co2FeSi Heusler alloy glass-covered microwires with a metallic nucleus diameter of about 4.4 µm and total sample diameter of about 17.6 μm by the Taylor–Ulitovsky Technique. This ...
Review of Helical Magnetic Structures in Magnetic Microwires
(MDPI, 2022-07-23)
We provide an overview of the helical magnetic structures in magnetic microwires. Having analyzed the experimental data describing the magnetic behavior of magnetic microwires since the 1990s, we found indirect evidence ...
Development of Magnetically Soft Amorphous Microwires for Technological Applications
(MDPI, 2022-01-07)
Amorphous magnetic microwires can be suitable for a variety of technological applications due to their excellent magnetic softness and giant magnetoimpedance (GMI) effect. Several approaches for optimization of soft magnetic ...
Tuning of Magnetoimpedance Effect and Magnetic Properties of Fe-Rich Glass-Coated Microwires by Joule Heating
(MDPI, 2022-01-29)
The influence of Joule heating on magnetic properties, giant magnetoimpedance (GMI) effect and domain wall (DW) dynamics of Fe75B9Si12C4 glass-coated microwires was studied. A remarkable (up to an order of magnitude) ...
Inertial domain wall characterization in layered multisublattice antiferromagnets
(Elsevier, 2022-10)
The motion of a Neel-like 180 degrees domain wall induced by a time-dependent staggered spin-orbit field in the layered collinear antiferromagnet Mn2Au is explored. Through an effective version of the two sublattice nonlinear ...
Influence of Tartrate Ligand Coordination over Luminescence Properties of Chiral Lanthanide-Based Metal–Organic Frameworks
(MDPI, 2022-11-13)
The present work reports on a detailed discussion about the synthesis, characterization, and luminescence properties of three pairs of enantiopure 3D metal–organic frameworks (MOFs) with general formula {[Ln2(L/D-tart)3( ...
