Compositions for reinforcing substrates, reinforced panels manufactured from those compositions, and methods of manufacture are disclosed. A composition may be composed of a base resin binder, a reinforcing fiber, a toughener, a heat curing agent, a cure accelerating agent, a sagging resistance agent, and a reinforcing agent. A coating of this composition can be applied upon a substrate, such as a steel or aluminum substrate. By heating the coating such that the coating cures upon the substrate, a reinforced substrate may be produced. The substrate may be sized and configured as a panel so that it could be used as an automotive panel. The low density and strong characteristics of the cured coating may allow for thin, lightweight automotive panels to be produced which provide higher milage. Such panels may also be effective at reducing vibration-generated noise that may otherwise result from a thin automotive panel.

Coating systems, composite articles produced from the coating systems, and methods for producing the composite articles are presented. In one embodiment, a coating system comprises a water-based substrate composition comprising an acrylic latex resin and a two-component water-based clearcoat composition. The two-component water-based clearcoat composition comprises a clearcoat binder component and a clearcoat crosslinker component. The clearcoat binder component comprises a water-dilutable, hydroxyl-functional (meth)acrylate copolymer. The clearcoat crosslinker component comprises a polyisocyanate compound with side-ended -NCO groups.A hardened film of the water-based clearcoat composition with a film thickness of 67.5 µm, applied over a hardened film of the water-based undercoat composition with a film thickness of 20 µm on a substrate, shows a popping density of less than about 3 pops per square centimeter, as measured by visual observation with the naked eye at a distance of 30 cm under a fluorescent light source.

Integrated circuitry comprising transistor structures having a channel portion over a base portion of fin. The base portion of the fin is an insulative amorphous oxide, or a counter-doped crystalline material. Transistor structures, such as channel portions of a fin and source and drain materials may be first formed with epitaxial processes seeded by a front side of a crystalline substrate. Following front side processing, a backside of the transistor structures may be exposed and the base portion of the fin modified from the crystalline substrate composition into the amorphous oxide or counter-doped crystalline material using backside processes and low temperatures that avoid degradation to the channel material while reducing transistor off-state leakage.
