Confinement in Metal‐Organic Frameworks as a Route to Harnessing Liquid Barocalorics in the Solid‐State

Advanced Functional Materials, EarlyView.
Encapsulation of solid–liquid barocalorics (BC) within MOFs harnesses their colossal BC performance whilst allowing active control of BC properties through BC‐MOF interactions. ABSTRACT Barocaloric (BC) effects at liquid–vapor transitions in hydrofluorocarbons drive most commercial technologies used for heating and cooling in the heating, ventilation ...

Messianism and Astronomical Events during the First Four Centuries of Islam

Revue des Mondes Musulmans et de la Méditerranée, 2000
Messianism and astronomical events are interconnected from the very earliest period of Islam. Although we do not know whether the appearance of comets and supernovae influenced the Prophet Muhammad to believe that the end of the world was imminent as he ...

Earliest datable records of aurora-like phenomena in the astronomical diaries from Babylonia [PDF]

, 2016
The astronomical diaries from Babylonia (ADB) are excellent sources of information of natural phenomena, including astronomical ones, in pre-Christ era because it contains the record of highly continuous and systematic observations.

Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

Advanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Algol as Horus in the Cairo Calendar: The Possible Means and the Motives of the Observations

Open Astronomy, 2018
An ancient Egyptian Calendar of Lucky and Unlucky Days, the Cairo Calendar (CC), assigns luck with the period of 2.850 days. Previous astronomical, astrophysical and statistical analyses of CC support the idea that this was the period of the eclipsing ...

La discussion par Kummer d’une quadrature sur la réfraction astronomique : commentaire historique

Comptes Rendus. Physique, 2023
In an 1860 memoir, Kummer (1810–1893) discusses analytically the consequences of light rays’ quadrature in a spherically symmetrical medium. This fertile approach is illustrated here by showing its graphical translation using the Young–Kattawar diagram ...

Comprehensive In Vitro Profiling Demonstrates Successful Immune Evasion of Bioengineered Immune‐Shielded Heart Valves

Advanced Healthcare Materials, EarlyView.
Living donor heart valves offer superior durability for pediatric patients but trigger immune rejection. Lentiviral delivery of viral immune‐evasion genes US2 and Serpin b9 into donor valve cells and valve tissue suppresses HLA expression, reduces PBMC clustering and cytotoxic killing, and induces transcriptional immune‐tolerance programs, paving the ...
