Design, pultrusion manufacturing, characterization, and reliability testing of a novel PMMA-based glass FRP composite material

open access: yesTransportation Engineering, 2022
Thermosetting resins have a limited ability to absorb impacting energy and deform in the transversal direction. Thermoplastics, on the other hand, are reformable meaning their shape can be modified after the polymerization process has occurred.

Superconducting HfO2-YBa2Cu3O7-δ nanocomposite films deposited using ink-jet printing of colloidal solutions [PDF]

open access: yes, 2019
To reduce the fabrication costs while maximizing the superconducting and pinning properties of YBa2Cu3O7−δ (YBCO) nanocomposite films, the drop-on-demand ink-jet printing technique was used to deposit colloidal YBCO inks onto LaAlO3 substrates.

A Carbocation Substituted Clay and its Styrene nanocomposite [PDF]

open access: yes, 2004
A substituted tropylium ion can be ion-exchanged onto montmorillonite to give a novel organically-modified clay. One can prepare a polystyrene nanocomposite of this clay by emulsion, but not bulk, polymerization.
