Chemical Upcycling of PET Waste towards Terephthalate Redox Nanoparticles for Energy Storage
(MDPI, 2021-11-03)Over 30 million ton of poly(ethylene terephthalate) (PET) is produced each year and no more than 60% of all PET bottles are reclaimed for recycling due to material property deteriorations during the mechanical recycling ... -
Coexistence of Superconductivity and Spin-Splitting Fields in Superconductor/Ferromagnetic Insulator Bilayers of Arbitrary Thickness
(American Physical Society, 2021-05-19)Ferromagnetic insulators (FI) can induce a strong exchange field in an adjacent superconductor (S) via the magnetic proximity effect. This manifests as spin splitting of the BCS density of states of the superconductor, an ... -
Coherent coupling between vortex bound states and magnetic impurities in 2D layered superconductors
(Nature, 2021-08-03)Bound states in superconductors are expected to exhibit a spatially resolved electron-hole asymmetry which is the hallmark of their quantum nature. This asymmetry manifests as oscillations at the Fermi wavelength, which ... -
Conditional Wave Function Theory: A Unified Treatment of Molecular Structure and Nonadiabatic Dynamics
(American Chemical Society, 2021-11-09)[EN] We demonstrate that a conditional wave function theory enables a unified and efficient treatment of the equilibrium structure and nonadiabatic dynamics of correlated electron-ion systems. The conditional decomposition ... -

[EN]In the present work, crystallization of a soluble nucleator N, N′, N″-tricyclohexyl-1,3,5-benzenetricarboxylamide (TMC-328) in a poly(l-lactic acid) (PLLA) matrix has been studied at different temperatures. Based on ... -
Effect of the valence state on the band magnetocrystalline anisotropy in two-dimensional rare-earth/noble-metal compounds
Blanco Rey, María; ; ; ; ; ; Ortega Conejero, José Enrique ; ; (American Physical Society, 2022)
[EN] In intermetallic compounds with zero orbital momentum (L = 0) the magnetic anisotropy and the electronic band structure are interconnected. Here, we investigate this connection in divalent Eu and trivalent Gd intermetallic ... -
Elucidating the Facet-dependent Selectivity for CO2 Electroreduction to Ethanol of Cu-Ag Tandem Catalysts
(ACS, 2021-04-07)Despite being desirable high-value products of the electrochemical CO2 reduction reaction (CO2RR), alcohols are still obtained with lower selectivity compared to hydrocarbons and the reaction pathways leading to their ... -
Engineered Magnetization and Exchange Stiffness in Direct-Write Co-Fe Nanoelements
(American Institute of Physics, 2021-01-11)Media with engineered magnetization are essential building blocks in magnonics, spintronics, and superconductivity. However, the established thin film and lithographic techniques insufficiently suit the realization of ... -
Engineering Three-Dimensional Moire Flat Bands
(American Chemical Society, 2021-09-22)Twisting two adjacent layers of van der Waals materials with respect to each other can lead to flat two-dimensional electronic bands which enables a wealth of physical phenomena. Here, we generalize this concept of so-called ... -
Excited-state band structure mapping
(American Physical Society, 2022-02-15)[EN] Angle-resolved photoelectron spectroscopy is an extremely powerful probe of materials to access the occupied electronic structure with energy and momentum resolution. However, it remains blind to those dynamic states ... -
