In vivo dosimetry for proton therapy: A Monte Carlo study of the Gadolinium spectral response throughout the course of treatment

Medical Physics, Volume 52, Issue 4, Page 2412-2424, April 2025.
Abstract Background In proton radiotherapy, the steep dose deposition profile near the end of the proton's track, the Bragg peak, ensures a more conformed deposition of dose to the tumor region when compared with conventional radiotherapy while reducing the probability of normal tissue complications.

Orbital ordering promotes weakly-interacting S=1/2 dimers in the triangular lattice compound Sr3Cr2O8

, 2008
The weakly interacting S=1/2 dimers system Sr3Cr2O8 has been investigated by powder neutron diffraction and inelastic neutron scattering. Our data reveal a structural phase transition below room temperature corresponding to an antiferro-orbital ordering ...

Synthesis, Characterization, and Measurement of New 1144‐Type Iron‐Based Superconductors: A Systematic Review

Nano Select, Volume 6, Issue 4, April 2025.
XYFe4As4 samples were synthesized by the Flux Method and Solid‐State Reaction Method (SSR). The flux method is a viable method for synthesizing 1144‐type single‐crystalline FeBSCs that uses a molten metal salt, called flux, to dissolve precursor materials and promote crystal growth of the desired XYFe4As4 sample.

Intrusion of quantum crystallography into classical lands

Acta Crystallographica Section B, Volume 81, Issue 2, Page 168-180, April 2025.
One hundred years after the quantum theory established position and momentum as incompatible quantities, quantum crystallography offers a way to visualize electron phase space behaviour in crystals.This article, written on the occasion of the International Year of Quantum Science and Technology, explores the development of alternative approaches to ...
