Controllable Black‐to‐Yellow Phase Transition by Tuning the Lattice Symmetry in Perovskite Quantum Dots

open access: yesSmall, Volume 19, Issue 47, November 22, 2023., 2023
This work reveals the underlying phase transition mechanism of cesium lead iodide quantum dot (CsPbI3 QD) films by investigating the distinct phase transition behaviours under two different temperature profiles–instant heating and slow heating. In situ grazing‐incidence wide‐angle and small‐angle X‐ray scattering (GIWAXS/GISAXS) data suggest that with ...

Branching into heritage: the genesis of the Anne Frank Tree and its multiplications

open access: yesJournal of the Royal Anthropological Institute, Volume 29, Issue 2, Page 363-382, June 2023., 2023
Abstract This ethnography contributes to the field of Holocaust heritage studies by exploring the paradoxical tendencies of memorial proliferation and oblivion. The topic of investigation is the genesis and multiplications of the so‐called ‘Anne Frank Tree’, the horse chestnut tree behind the Secret Annex that Anne Frank wrote about in her diary ...

Black‐Yellow Bandgap Trade‐Off During Thermal Stability Tests in Low‐Temperature Eu‐Doped CsPbI3

open access: yesSolar RRL, Volume 6, Issue 6, June 2022., 2022
Two sides of the same coin: the yellow δ‐phase grows over time at the expense of the black γ‐phase, following an Avrami like pathway after an incubating delay time. This kinetic study versus temperature has a predictive valence and allows identifying the beneficial role of Eu in stabilizing the black γ‐phase in the range 30–100 °C. The black γ‐phase of

Formation of CsPbI3 γ‐Phase at 80 °C by Europium‐Assisted Snowplow Effect

open access: yesAdvanced Energy and Sustainability Research, Volume 2, Issue 7, July 2021., 2021
The addition of Eu in the mother solution and the use of low formation temperature cooperate in reducing the grain size and in increasing the barrier for mass exchange that finally extends the stability window of the γ‐phase at room temperature. Herein, the convenient interplay between Eu incorporation and morphology to form the perovskite (PSK) γ ...

All‐Inorganic Cesium‐Based Hybrid Perovskites for Efficient and Stable Solar Cells and Modules

open access: yesAdvanced Energy Materials, Volume 11, Issue 23, June 17, 2021., 2021
This review aims to discuss challenges and recent advances in all‐inorganic perovskites for advanced photovoltaics. After discussing the structural and electronic properties of the materials, the focus of this review moves towards all‐inorganic perovskite solar cells, reporting the most effective approaches to improve device performance.

Simple and Environmentally Friendly Solution Synthesis of CsPbI3 Nanoribbons: Investigating the Reversible δ‐ to γ‐Phase Transition

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
Cesium lead iodide (CsPbI3) nanoribbons obtained through mild condition synthesis are herein reported without surfactant species and toxic solvent starting from β‐diketonate complexes of Cs and Pb. The morphological and structural features, together with the thermal stability and phase transitions from the yellow δ to the black α and γ‐CsPbI3 phases ...

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) relating to an analysis of the health risks associated with exposure to caterpillars with stinging hairs and the development of management recommendations

open access: yesFood Risk Assess Europe, Volume 3, Issue 2, April 2025.
Abstract Several species of Lepidoptera with caterpillars bearing urticating hairs are increasing their range in metropolitan France from year to year, such as the pine processionary (Thaumetopoea pityocampa Denis et Schiffermüller 1775) whose presence was historically limited to the south of France, and which is gradually being observed in the north ...

Structural Disorder by Octahedral Tilting in Inorganic Halide Perovskites: New Insight with Bayesian Optimization

open access: yesSmall Structures, Volume 5, Issue 11, November 2024.
Structural disorder phenomena of inorganic halide perovskites in terms of octahedral tilting around three lattice axes are computationally studied. Bayesian optimization machine learning technique assists to rapidly converge the three‐dimensional potential energy surfaces.

Les espaces publics dans les territoires de densités intermédiaires : conceptions, usages et potentialités [PDF]

open access: yes, 2014
National audiencePublic spaces in periurban areas often have a poor image. They are considered either as insufficiently developed, or as emblematic of privatised town development.
