Neutron irradiation of flint glasses for optics in ITER

Nuclear Materials and Energy, 2018
Radiation-resistant optics, which is necessary to transfer light from plasma to detectors in ITER, will be exposed to neutron fluxes at D-T stage. Achromatic lenses located in the interspace and in the port cell areas must have a sufficient optical ...

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

Advanced Materials, Volume 38, Issue 31, 2 June 2026.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Dosimetric platform and a genuine Raman protocol for passive estimation of fast-neutron fluence in irradiated SiC and SiC topped with epitaxial graphene

Results in Physics
The article introduces a genuine ex-situ measurement protocol to estimate the integrated flux of mostly fast (1-2 MeV) neutrons. It is verified up to the fluence of 6.5 × 1018 n/cm2.

Giant Bulk Photovoltaic Effect in Crystal Orientation Restructured Quasi‐Epitaxial BaTiO3 Films on Silicon Substrates

Small, Volume 22, Issue 31, 2 June 2026.
ABSTRACT The bulk photovoltaic (BPV) effect in ferroelectric (FE) materials enables the direct conversion and exchange of information between the optical and electrical domains in applications such as photonic computing and photodetection. Although the above‐bandgap open‐circuit voltage in the FE BPV effect permits a much higher photovoltage in ...

Why LA‐ICPMS Fission‐Track Age Data Are So Dispersed? A Pseudo‐EDM Solution

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Fission track (FT) dating is a well‐established thermochronological technique widely used to reconstruct rocks' thermal histories. Over the past two decades, development of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA‐ICPMS) has significantly advanced the application of FT dating by enabling rapid measurements of uranium ...

Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

Chemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.
