Aromaticity Regulation in Isostructural Metal‐Organic Frameworks for Propyne Storage and Propylene Purification

ABSTRACT We report the exceptional propyne (C 3 H 4 ) storage and propylene (C 3 H 6 ) purification in a metal‐organic framework, PKU‐101, controlled via regulation of aromaticity. The pyrene‐fused pore interior of PKU‐101 provides multiple C─H···π interactions for alkyne, result...

Adsorption Behavior of C10 Amino Acid Surfactants at the Air/Water Interface: Implications for Membrane Compatibility

Abstract Amino acid-based surfactants represent a promising class of biocompatible and biodegradable amphiphiles with increasing relevance in pharmaceutical and biomedical applications. Despite their growing use, a quantitative understanding of their interfacial packing and how t...

The Characterization of a Compact CLLB:Ce Scintillation Detector for Mixed-Field Monitoring at a Muon Facility

Compact scintillation detectors with simultaneous gamma and neutron sensitivity are increasingly relevant for mixed-field monitoring and nuclear measurements under size and cost constraints. This work characterizes a compact Cs2LiLaBr6:Ce (CLLB:Ce) detector with integrated SiPM r...

Non-line-of-sight terahertz communications enabled by reflection and transmission

Abstract Terahertz communication is expected to be a key technology for future wireless networks, offering ultra-high capacity, beyond the limits of conventional radio-frequency systems. To enable practical implementation, investigating non-line-of-sight terahertz links is essent...

Without Scratching the Surface: Depth Profiling Compositional Muon Analysis of Ancient Faience From Egypt and Sudan

ABSTRACT The specific depth‐profiling capabilities of the muonic x‐ray emission spectroscopy (μ‐XES) technique have proved to be effective for examination of the elemental distribution within ancient coins. This ‘layered’ analysis can also be applied to the examination of ancient...

Towards real-time surrogate-free Bayesian inversion for neutron reflectometry

Abstract Neutron reflectometry (NR) is a key enabling technology for many areas of scientific development. Although the forward reflectivity model is well-known, inferring the physical properties of a sample from NR data requires the solution of an inverse problem. Increasingly,...

Correlated Polymer‐Proton Hopping Enables Water‐Independent Fast Proton Transport in Poly(Ionic Liquid) Membranes

Polymer electrolyte membranes composed of ionic liquids (IL), capable of conducting protons efficiently at elevated temperatures, without external humidification, could transform fuel cell technology. However, the molecular origins of such proton transport remain poorly understoo...

Kelvin–Helmholtz vortices at the magnetopause during northward IMF: multi-satellite observations of energy transport and plasma redistribution

The Kelvin–Helmholtz (KH) instability is a fundamental plasma process in many astrophysical environments; its vortices facilitate solar wind energy transport and plasma mixing. We investigate the energy flux density distribution and fluctuations of a typical KH vortex event obser...

A ComplexSpin-Transition Thermal Hysteresis Unlockedby Two Competing Symmetry-Breakings

Abstract The spin-crossover material [Fe(NH2trz)3](NO3)2 belongs to the class of 1D triazole-based polymeric SCO complexes. It exhibits a thermal phase transition, with a 28 K wide thermal hysteresis, characterized by phase transition temperatures T↑ = 346 K upon warming and T↓ =...
