Cryogenic TDS Platform for Quantitative Hydrogen Isotope (H2/D2/HD) Separation via Quantum Sieving in Porous Materials

open access: yesSmall, EarlyView.
The AC‐TDS enables precise hydrogen isotope analysis over a wide temperature range (15–900 K), allowing both physisorption and chemisorption processes to be investigated under gas exposure conditions. Through calibration, this system achieves reliable quantitative desorption analysis, including direct quantification of H2, D2, and HD under mixed ...

A Generalized Automated Framework for Thermal Characterization: From Bulk Materials to Complex Heterostructures

open access: yesSmall, EarlyView.
An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

Structural Profiling of Lipid Nanoparticles at Sub‐10 nm Resolution via AF4 Coupled Online to SAXS and SANS

open access: yesSmall Methods, EarlyView.
Dilution‐controlled AF4 coupled with SAXS and, for the first time, SANS enables high‐resolution characterization of non‐spherical lipid nanoparticles. Enhanced scattering contrast and D2O‐based measurements resolve particle features down to ∼5 nm and reveal shape distributions.

A Review on Jahn–Teller Distortions in Prussian Blue Analogs Molecular Magnets

open access: yesThe Chemical Record, EarlyView.
This review highlights the central role of the Jahn–Teller effect in governing structural stability and electrochemical performance in Prussian blue analogs (PBAs). It establishes clear structure–property relationships and summarizes effective mitigation strategies, providing design guidelines for developing stable, high‐performance PBA‐based energy ...

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

open access: yesJournal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

High‐flux, moderate‐bandwidth, high‐energy X‐rays from lapped Si(111) crystals in a double‐crystal monochromator

open access: yesJournal of Synchrotron Radiation, EarlyView.
Lapped Si(111) crystals in a double‐crystal monochromator provide high‐flux, spectrally pure, and moderate‐bandwidth X‐ray beams at 100 keV, offering a robust and cost‐effective alternative to perfect‐crystal and multilayer optics.Lapping the surfaces of Si(111) crystals in a double‐crystal monochromator significantly increases the intensity of high ...

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Reactivity in the theory of the stationary nuclear fission wave

open access: yesЯдерна фізика та енергетика, 2016
We studied axial motion of the stationary nuclear fission wave in the cylindrical core of the traveling wave reactor (known also as CANDLE) using an effective one-dimensional model of the fast spectrum reactor with uranium plutonium fuel.
