Abstract: Methods of nanomanufacturing based on continuous additive nanomanufacturing at fluid interfaces (CANFI). This approach is a fabrication technique that involves, for example, photocuring or “printing” self-assembled layers. CANFI presents a fabrication capability with significant transformative potential improve (i) the spatial resolution, (ii) the speed, and (iii) the range of material compositions that can be printed. Various articles of manufacture can be made using the methods.

Abstract: A methodology for synthesizing a nanoparticle batch, such as but not limited to a metal chalcogenide nanoparticle batch and further such as but not limited to a metal sulfide nanoparticle batch is predicated upon an expectation and observation that at elevated concentrations of at least one reactant material within a heat-up nanoparticle batch synthesis method, the resulting nucleated batch comprises nanoparticles that may be dimensionally focused to provide a substantially monodisperse nanoparticle batch. The embodied methodology is also applicable to a continuous reactor. The embodied methodology also considers viscosity as a dimensionally focusing result effective variable.

Abstract: Growth of Group IV nanowires with a substrate and a Group IV metalloid is performed using resistive or inductive heating of the substrate. A roll-to-roll process enables a metal surface to move through a reaction environment while reacting with a stream or bath of precursor to form the nanowire-metal complex. The Group IV nanowires on a surface of the substrate can have a surface loading greater than 10 mg/cm2.

Abstract: Methods for fabricating a nanowire composite, and a resulting article that includes the nanowire composite, are all adaptable to roll-to-roll processing by using a flexible substrate including a group IV nanowire growth surface, and locating and forming a group IV nanowire material layer upon the group IV nanowire growth surface. Under particular conditions of processing, group IV nanowire material layer nanowires may be located and formed perpendicular to a plane of the flexible substrate. Exemplary roll-to-roll processing apparatus are also considered.
