On the ontology of fictional characters: A semiotic approach

open access: yesSign Systems Studies, 2009
Why are we deeply moved by the misfortune of Anna Karenina if we are fully aware that she is simply a fictional character who does not exist in our world? But what does it mean that fictional characters do not exist? The present article is concerned with

Effect of Atomic Layer Deposition of Ultra‐Thin Oxide on Reactivity and Durability of Perovskite Oxygen Electrodes

open access: yesAdvanced Materials, EarlyView.
This table of contents illustrates that the mechanism for mitigating Sr segregation depends strongly on the chemistry of the coating layer. HfO2 electrostatically stabilizes the surface by lowering the surface oxygen vacancies, which serve as the driving force for Sr migration. On the other hand, Al2O3 and Fe2O3 react with segregated Sr to form Sr‐Al‐O

Integrating Vibrio natriegens for Photon Manipulation in Living Lighting Devices

open access: yesAdvanced Materials, EarlyView.
Rationalization of genetic and material engineering tools has enabled the engineering of fluorescent Vibrio natriegens (V. natriegens) to fabricate straightforward, highly emissive and stable V. natriegens‐silicones color filters for the first red‐emitting bacteria‐hybrid light‐emitting diodes. This pinpoints V. natriegens as a high‐performance protein

COFs on MOFs: Layer‐by‐Layer Synthesis of MOF@COF Nanoparticles with Synergistic Adsorption

open access: yesAdvanced Materials, EarlyView.
A layer‐by‐layer strategy enables the growth of crystalline covalent organic framework (COF) shells on metal–organic framework nanoparticles, creating core–shell structures with tunable porosity. Ordered interstitial mesopores are formed during shell growth, which are connected with the COF's intrinsic micropores, thereby enhancing water sorption. This
