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.

Neutrons for rafts, rafts for neutrons

The European Physical Journal E, 2013
The determination of the structure of membrane rafts is a challenging issue in biology. The selection of membrane components both in the longitudinal and transverse directions plays a major role as it determines the creation of stable or tunable platforms that host interactions with components of the outer environment.

Neutron-Proton and Neutron-Neutron Scattering at High Energies

Physical Review, 1949
The phase method and the Born approximation is used to calculate the cross sections of high energy neutrons scattered by protons and neutrons. Various exchange theories are considered for both, central and tensor forces of rectangular and Yukawa well shape.

Neutron Production, Neutron Facilities and Neutron Instrumentation

Reviews in Mineralogy and Geochemistry, 2006
The main natural source of free neutrons is secondary radiation from cosmic radiation (creation of particles by interactions of cosmic radiation particles with atoms of the earth’s atmosphere). The main sources of neutrons generated artificially are nuclear reactors. Free neutrons have an average lifetime of about 888 seconds (e.g., Mampe et al.
