Red‐Sensitive Photopolymerizable Glass for Fabrication of Holographic Optical Elements

open access: yesAdvanced Optical Materials, EarlyView.
This study presents a novel photopolymerizable glass capable of optical patterning using red‐wavelength laser exposure. Red‐light sensitivity was achieved through the incorporation of a photoinitiating system composed of methylene blue (MB) and N‐phenylglycine (NPG).

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

open access: yesAdvanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

Synthesis and tribology of Sialon/TiB2 ceramic composites [PDF]

open access: yes
The inclusion of TiB2 particles in a Si3N4 or sialon matrix has the potential to improve the materials properties over those of the Si3N4 alone. The combination of the excellent properties of sialon and the high hardness of the TiB2 makes these ...
