Quantum Emitters in Hexagonal Boron Nitride: Principles, Engineering and Applications

open access: yesAdvanced Functional Materials, EarlyView.
Quantum emitters in hexagonal boron nitride have emerged as a promising candidate for quantum information science. This review examines the fundamentals of these quantum emitters, including their level structures, defect engineering, and their possible chemical structures.

(Re)Imagining Flyover: An Introduction

open access: yesJournal of the Austrian Association for American Studies
This introduction to the special issue titled "(Re)Imagining Flyover Fictions" theorizes the flyover trope (as in "flyover country/state") as a critical concept in cultural studies in order to make it an abstract tool to explore, among others, the ...

Single Pair of Weyl Points Evolve From Spin Group‐Protected Nodal Line in Half‐Metallic Ferromagnet V3S4

open access: yesAdvanced Functional Materials, EarlyView.
A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Fiction and Thought Experiment - A Case Study [PDF]

open access: yes, 2016
Many philosophers are very sanguine about the cognitive contributions of fiction to science and philosophy. I focus on a case study: Ichikawa and Jarvis’s account of thought experiments in terms of everyday fictional stories.

Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Fictions du vide. Scénario pour une enquête cinématographique et littéraire [PDF]

open access: yes, 2013
Le présent article, sous la double forme d’un scénario et d’une enquête, se veut une réflexion volontairement ouverte sur ce qui sera défini comme les « fictions du vide », sur leurs différents modes d’apparition et sur les diverses figures qu’elles sont
