Advanced Materials, EarlyView.In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

L’impact environnemental d’une habitation écologique
Revue des Énergies Renouvelables, 2010 Une maison écologique, désigne plus un concept qu’un type défini d’habitation. L’idée est de combiner les différents modes de chauffage, de ventilation, d’alimentation des appareils pour réduire massivement la consommation d’énergie, donc une ...

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Advanced Materials, EarlyView.Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Digital Economy: The Evolution of the Digital Economy
Ubiquity, 2023 We are in the early stages of a historical transition from the industrial economy of the past two centuries to a new kind of a 21st century digital economy. This transition is being driven by dramatic advances in digital technologies and the internet over the past two decades, as well as the more recent advances in big data and artificial intelligence.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Marx’ macro-economie avant la lettre [PDF]
, 2014 De term macro-economie dateert uit 1933, maar macro-economisch redeneren is eerder al geleidelijk ontstaan. Dit artikel bespreekt belangrijke macro-economische aanzetten in Marx’ hoofdwerk ‘Das Kapital’.

Kruis en Munt:De Raakvlakken van Economie en Theologie
, 2021 Paul van Geest en Lans Bovenberg laten in ‘Kruis en munt’ zien dat de economie vandaag de dag dringend behoefte heeft aan bezinning. De mens is niet uitsluitend homo economicus, maar veel meer dan dat.

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Advanced Materials, EarlyView.Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.
