Accurate simulations of magnetic excitations in the neutron simulation package McStas

Journal of Applied Crystallography, EarlyView.
We present an accurate algorithm for simulating neutron scattering from spin waves in the ray‐tracing package McStas.An algorithm for the accurate simulation of neutron scattering from magnetic excitations has been developed and implemented as new component for the neutron ray‐tracing software McStas.

Modeling small‐angle scattering data of porous and/or bicontinuous structures in n dimensions

Journal of Applied Crystallography, EarlyView.
A small‐angle scattering fitting function is derived for porous materials with arbitrary fractal dimension. It includes a correlation peak and a power law at higher q.Fractal structures are often observed in small‐angle scattering experiments where a simple power law q−α describes the scattering intensity over many orders of magnitude.

Unraveling the symmetry of Al5C3N

Acta Crystallographica Section B, EarlyView.
From experimental and theoretical techniques employed in this thorough reexamination of the structure of Al5C3N, the crystal structure is better described in centrosymmetric space group P63/mmc (No. 194) rather than in the previously reported noncentrosymmetric space group P63mc (No. 186).High‐temperature ceramic compound Al5C3N belongs to the scarcely

Structural and magnetic investigations of the Weyl semimetal family CeAlSi1–xGex

Acta Crystallographica Section B, EarlyView.
A systematic investigation is reported of the structural and magnetic evolution in the CeAlSi1–xGex series, combining X‐ray and neutron diffraction with magnetization measurements on polycrystalline samples and single crystals. Chemical substitution leads to a continuous lattice expansion and a suppression of the ferromagnetic ordering temperature ...

Investigating transthyretin variants H88R and I107V in amyloid priming: From destabilization to complete dissociation

The FEBS Journal, EarlyView.
Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations
