Advanced Energy Materials, EarlyView.The transition metal oxide is precisely deposited on the catalyst surface via atomic layer deposition (ALD), forming a protective layer with catalytic activity. Electrochemical experiments, theoretical calculations, and in situ X‐ray absorption spectroscopy (XAS) battery testing collectively demonstrate that the modified transition metal oxide ...

Les systèmes d’appréciation de la valeur énergétique des aliments pour le porc
INRAE Productions Animales, 1993 Pour un même aliment, il peut être attribué différentes valeurs énergétiques selon l’étape de l’utilisation de l’énergie qui est considérée (énergie digestible : ED, énergie métabolisable : EM ou énergie nette : EN) et selon le mode de prédiction au ...

Energy use efficiency of organic and agroforestry farming systems [PDF]
, 2013 Im Versuchsbetrieb Scheyern (Süddeutschland) wurde in Feldexperimenten die Energienutzungseffizienz (EUE) ökologischer Anbausysteme analysiert. Die EUE wurde für verschiedene Systemebenen - die Fruchtarten, die Fruchtfolge sowie Agroforstsysteme (AFS ...

Advanced Energy Materials, EarlyView.Halide segregation (HS) in mixed‐halide wide‐bandgap (WBG) perovskites is key to the stability of perovskite‐based tandem cells and a central focus of large‐scale research efforts. Here, we find that the underlying reason for the poor stability of cells prone to HS is enhanced ionic losses during operation. Furthermore, we identified irreversible ionic

Rola odnawialnych źródeł energii w Krajowym Systemie Elektroenergetycznym
Prace Komisji Geografii Przemysłu Polskiego Towarzystwa Geograficznego, 2015 Udział odnawialnych źródeł energii (OZE) w Krajowym Systemie Elektroenergetycznym (KSE) od kilku lat systematycznie wzrasta. W Polsce energia ze źródeł odnawialnych obejmuje energie: promieniowania słonecznego, wiatru, wody, zasobów geotermalnych oraz ...

PORTFOLIO OPTIMIZATION IN ELECTRICITY TRADING WITH LIMITED LIQUIDITY [PDF]
In principle, portfolio optimization in electricity markets can make use of the standard mean-variance model going back to Markowitz. Yet a key restriction in most electricity markets is the limited liquidity.

Advanced Energy and Sustainability Research, EarlyView.This graphical abstract presents an integrated workflow for optimizing perovskite thin film fabrication by tuning ink rheology, refining processing parameters, and controlling crystallization. Viscosity control and process optimization precisely regulate wet film thickness and drying time, while crystallization directed by solvent additives yields ...
