A general but still unknown characteristic of active oxygen evolution electrocatalysts
(Royal Society of Chemistry, 2023-04)
The unsatisfactory electrocatalysis of the oxygen evolution reaction (OER) is a major hurdle for the sustainable production of hydrogen using water electrolyzers. Besides, most state-of-the-art catalysts are based on ...
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 ...
Structure-sensitive scaling relations among carbon-containing species and their possible impact on CO2 electroreduction
(Elsevier, 2021-01-24)
The arduous modelling of reactions at heterogeneous catalysts is greatly simplified when adsorption-energy scaling relations between intermediates exist. The offset of these linear relations is structure-independent when ...
Enhancing CO2 Electroreduction to Ethanol on Copper-Silver Composites by Opening an Alternative Catalytic Pathway
(ACS, 2020-03-16)
A fundamental question in the electrochemical CO2 reduction reaction (CO2RR) is how to rationally control the catalytic selectivity. For instance, adding a CO-producing metal like Ag to Cu shifts the latter’s CO2RR selectivity ...
Self-propelling colloids with finite state dynamics
(PNAS, 2023-03)
Endowing materials with the ability to sense, adapt, and respond to stimuli holds the key to a progress leap in autonomous systems. In spite of the growing success of macroscopic soft robotic devices, transferring these ...
Topologically-mediated energy release by relativistic antiferromagnetic solitons
(American Physical Society, 2021-10-25)
[EN]Magnetic solitons offer functionalities as information carriers in multiple spintronic and magnonic applications. However, their potential for nanoscale energy transport has not been revealed. Here we demonstrate that ...
Walker-like domain wall breakdown in layered antiferromagnets driven by staggered spin-orbit fields
(Nature, 2020-10-29)
Within linear continuum theory, no magnetic texture can propagate faster than the maximum group velocity of the spin waves. Here, by atomistic spin dynamics simulations and supported by analytical theory, we report that a ...
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 ...
The influence of interfacial interactions on the conductivity and phase behaviour of organic ionic plastic crystal/polymer nanoparticle composite electrolytes
(Royal Society of Chemistry, 2020-02-21)
Organic ionic plastic crystals (OIPCs) have been recognised as promising solid-state electrolyte materials for next-generation energy storage devices. Recently, the addition of polymer nanofillers to OIPCs has led to the ...
Phase Transitions in Poly(vinylidene fluoride)/Polymethylene-Based Diblock Copolymers and Blends
(MDPI, 2021-07-24)
The crystallization and morphology of two linear diblock copolymers based on polymethylene (PM) and poly(vinylidene fluoride) (PVDF) with compositions PM23-b-PVDF77 and PM38-b-PVDF62 (where the subscripts indicate the ...
