Advanced Science, EarlyView.A Pt single‐atom‐loaded CuO sensing material is developed for acetone detection, demonstrating remarkably enhanced sensing performance. The introduction of Pt single atoms effectively activates the lattice oxygen of the CuO support. A new sensing mechanism based on the Mars‐van Krevelen catalytic mechanism is proposed, offering new insights into the ...

Advanced Science, EarlyView.The cascade supramolecular assembly of charge‐transfer arrays not only triggered a topological transformation from nanofiber to nanorod and vesicles, but also promoted single‐molecule phosphorescent resonance energy transfer, expanding phosphorescence emission at 500 nm to near‐infrared delayed fluorescence emission at 650 nm with a lifetime of 11.20 ...

Schwarzschild black hole and redshift rapidity: a new approach towards measuring cosmic distances
The European Physical Journal CAbstractMotivated by recent achievements of a full general relativistic method in estimating the mass-to-distance ratio of supermassive black holes hosted at the core of active galactic nuclei, we introduce the new concept redshift rapidity in order to express the Schwarzschild black hole mass and its distance from the Earth just in terms of ...

Advanced Science, EarlyView.Thanks to the appropriate structure preorganization of an N3O2‐pentadentate planar ligand, 2,6‐bis(2‐hydroxyphenylmethylaminomethyl)pyridine (H2saldamp) exhibits the strongest coordination affinity to UO22+ (log βU = 33.60) compared to ligands developed for uranium harvesting from seawater to date, as well as good separability of UO22+ from other metal

The Astrophysical Journal LettersWe use 47 gravitational-wave (GW) standard sirens from the third Gravitational-Wave Transient Catalog to calibrate distances in the strong gravitational lensing (SGL) system RXJ1131-1231 and constrain the Hubble constant ( H _0 ) via the distance sum ...

Advanced Science, EarlyView.A biomass‐derived additive synthesized from chitin, 3‐acetylamino‐5‐acetylfuran (3A5AF), resolves key stability issues such as uncontrolled dendrite growth, hydrogen evolution reaction, and corrosion of zinc anodes by reconstructing the solvation structure of the electrolyte and protecting the anode interface. ABSTRACT Aqueous zinc‐based batteries face

A 100 Mpc2 Structure Traced by Hyperluminous Galaxies around a Massive z = 2.85 Protocluster
The Astrophysical JournalWe present wide-field mapping at 850 μ m and 450 μ m of the z = 2.85 protocluster in the HS 1549+19 field using the Submillimetre Common-User Bolometer Array 2. Spectroscopic follow-up of 18 bright sources selected at 850 μ m, using the Northern Extended

Redshift and distances in a ΛCDM cosmology with non-linear inhomogeneities [PDF]
, 2012 Motivated by the dawn of precision cosmology and the wealth of forthcoming high-precision and volume galaxy surveys, in this paper we study the effects of inhomogeneities on light propagation in a flat Λ cold dark matter (ΛCDM) background. To this end we use exact solutions of Einstein’s equations as derived by Meures & Bruni where, starting from ...
