According to one embodiment, a product includes a composite film comprising a polymer layer directly adjacent a graphene layer. According to another embodiment, a process includes layering a graphene layer onto a polymer layer to form a composite film.

An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates on demand for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.

In a mist nozzle, a liquid stored in a liquid storage tank is pressurized by a liquid supplier and is supplied to the mist nozzle, so that a liquid flow is introduced from an upstream of a gas-liquid mixing section and a vicinity of a wall surface of the gas-liquid mixing section into the gas-liquid mixing section on an outer lid side. A pressurized gas is supplied from a gas supplier from a facing surface, so that a gas flow introduces into the gas-liquid mixing section and collides with the liquid flow, and a gas-liquid mixed flow is advanced to a spout portion while circulating the wall surface of the gas-liquid mixing section on the outer lid side. Therefore, it is possible to promote atomization of the liquid in the gas-liquid mixing section and spray a liquid having a smaller particle diameter.

A method is disclosed of three-dimensional (3D) free-form printing for coating free-form objects, the method including: arranging a free-form object in a Langmuir-Blodgett (LB) trough filed with a liquid, the LB trough designed based on a shape of the free-form object; arranging an LB film comprising a plurality of colloidal nanospheres on a surface of the liquid within the LB trough; and draining the liquid from the LB trough to form a self-assemble film of the colloidal nanoparticles on a surface of the free-form object.

A nanowire device and a method of making a nanowire device are provided. The device includes a plurality of nanowires functionalized with different functionalizing compounds. The method includes functionalizing the nanowires with a functionalizing compound, dispersing the nanowires in a polar or semi-polar solvent, aligning the nanowires on a substrate such that longitudinal axes of the nanowires are oriented about perpendicular to a major surface of the substrate, and fixing the nanowires to the substrate.
