Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and ...

The first 415-100 series sets allocated to Kyushu were 4-car units delivered from September 1978. These were formed KuHa 411-100 + MoHa 415-100 + MoHa 414-100 + KuHa 411-200. [2] Some sets later received life-extension refurbishment with transverse seating replaced by longitudinal seating. [2]
New Reds skipper Terry Francona wants his players to concentrate on getting ready for 2025 MLB season, one that won't include challenge system.
Left: individual linear polymer chains Right: Polymer chains which have been cross linked to give a rigid 3D thermoset polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (). [1]
