Dynamics of Radiation Damage in AlN Ceramics under High-Dose Irradiation, Typical for the Processes of Swelling and Hydrogenation

Crystals, 2020
The use of nitride ceramics, in particular AlN, as structural materials for nuclear power is primarily limited by their resistance to swelling and hydrogenation processes due to the accumulation of poorly soluble helium and hydrogen ions in the structure

Tailoring strain in SrTiO3 compound by low energy He+ irradiation [PDF]

, 2010
The ability to generate a change of the lattice parameter in a near-surface layer of a controllable thickness by ion implantation of strontium titanate is reported here using low energy He+ ions. The induced strain follows a distribution within a typical

Unraveling Chronic Pain: From Mechanisms and Risks to Diagnosis and Treatment

MedComm, Volume 7, Issue 4, April 2026.
Chronic pain arises through distinct molecular pathways categorized into nociceptive, neuropathic, and nociplastic types. Nociceptive pain begins with TRP channel activation in peripheral nociceptors, signaling via Aδ‐ and C‐fibers through the spinal dorsal horn and spinothalamic tracts to the brain, regulated by descending inhibition and involving ...

Study of the Surface-Layer Softening Effects in xLi₂ZrO₃–(1−x)Li₄SiO₄ Ceramics under Irradiation with He²⁺ Ions

Ceramics
The study investigates alterations in the mechanical and thermophysical properties of ceramics composed of xLi2ZrO3–(1−x)Li4SiO4 as radiation damage accumulates, mainly linked to helium agglomeration in the surface layer.

Systematic Study of PDMS Optical Waveguides for Pressure Sensing Using Design of Experiments

Journal of Applied Polymer Science, Volume 143, Issue 12, March 20, 2026.
A response surface methodology was used to systematically evaluate the impact of mix ratio and cure conditions on PDMS optical waveguide properties for pressure sensing. Mix ratio significantly influenced compression sensitivity, compressive modulus, and propagation loss, while cure temperature primarily affected refractive index.

Focused helium ion beam nanofabrication by near-surface swelling

Journal of Vacuum Science & Technology B
The focused helium ion beam microscope is a versatile imaging and nanofabrication instrument enabling direct-write lithography with sub-10 nm resolution. Subsurface damage and swelling of substrates due to helium ion implantation is generally unwanted. However, these effects can also be leveraged for specific nanofabrication tasks.

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Radiation Effects in Borides, Part I - Helium Release and Swelling in Irradiated Borides [PDF]

, 1962
The principal objective of the work being reported was to irradiate a variety of borides in order to assess the relationship of crystal structure to helium retention and structural changes. A secondary objective was to compare the irradiation behavior of powders and dense solids.
