Direct Growth of Transparent Boron Nitride Neutron Shielding Layer for Space Window

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Direct growth of sp2‐sp3 hybridized BN (HBN) on quartz, enabled by an h‐BN buffer, produces transparent and stable films up to 80 µm thick with high transmittance and strong neutron shielding, making HBN a promising candidate for space windows in long‐term lunar missions.

Ultrasmall Au10–12 Nanoclusters: A Novel Platform for 223Ra‐Targeted Tumor α‐Therapy

Exploration, Volume 6, Issue 2, April 2026.
Encapsulating 223Ra in Au10‐12 nanoclusters and functionalizing them with RGD peptides enables targeted α‐therapy and immune microenvironment remodeling in non‐osseous tumors like triple‐negative breast cancer. This study establishes a foundational framework for novel 223Ra‐labeled α‐radiopharmaceuticals and shows strong potential for clinical ...

MeV Neutron Production from Thermal Neutron Capture in {6}^Li Simulated with Geant4

, 2015
Various Li compounds are commonly used at neutron facilities as neutron absorbers. These compounds provide one of the highest ratios of neutron attenuation to $\gamma$-ray production. Unfortunately, the usage of these compounds can also give rise to fast

Independent verification of vendor‐issued dosimetric data for 106Ru brachytherapy using diode detectors with traceability to external beam standards for absorbed dose to water

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background Independent verification of the manufacturer‐provided dosimetry data for 106Ru ophthalmic brachytherapy applicators is crucial for safe and accurate treatment, yet a standardized, traceable method for clinical absolute dosimetry has been lacking. Purpose This work establishes a complete framework for traceable absorbed dose to water

GEANT4 Montecarlo simulations: a multithread approach [PDF]

Proceedings of The Golden Age of Cataclysmic Variables and Related Objects IV — PoS(GOLDEN 2017), 2018
In this paper we will show the hardware and software implementation of the gforcr computing cluster operating in the LCD laboratory at the IAPS / INAF headquarters in Rome. The comput- ing system is used to perform Monte Carlo simulations using the GEANT4 toolkit in multithread mode. The simulations are designed to evaluate and reduce the background of

Influence of Mars Topography on Radiation Dose Detected by the Mars Science Laboratory and Assessment of Mars Surface Albedo Radiation

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The Radiation Assessment Detector (RAD) on the Curiosity rover has been characterizing the Martian surface radiation field since 2012. The dose observed by RAD is influenced by a variety of factors, including an essential one, the terrain. After parking near Murray Buttes in September 2016 where it first detected a ∼5% decrease in dose rate ...
