An improved method for applying an electrically charged lubricant on an oppositely charged carcass trolley in a meat packing plant meeting the requirements of (1) adequate lubricity, (2) drip-resistance, (3) safety, (4) rust resistance, (5) economy of manufacture and use, and (6) the ability to be removed by cleaning methods is provided by preparing a mixture of mineral oil, a fatty acid, a silicone oil, and a polybutene, each being acceptable for incidental contact with food.

Embodiments relate to a method of manufacturing pinned nano-structures with tailored gradient properties. First and second compositions are provided, Each of the compositions includes a nano-structural material, a plurality of grain growth inhibitor nano-particles, and at least one of a tailoring solute and a plurality of tailoring nano-particles. Deposition layers are formed proximal to a substrate with each of the compositions through electrospray techniques.

A method and apparatus for fabrication of objects retaining nano-scale characteristics. A composition is provided comprising grain growth inhibitor particles in solution with a binding agent in a molten phase. An electric field and a magnetic field are generated with a combined extraction electrode. The composition is electrosprayed from a nozzle with the electric field to form a stream of droplets. The electric field drives the droplets toward a moving stage holding an object comprising successive deposition layers. The magnetic field limits dispersion of the stream of droplets. The stage is moved laterally as the stream of droplets impacts the object to form a current deposition layer of the object. The stage is moved vertically as necessary to maintain a target stand-off distance between the nozzle and a previous deposition layer of the object, based on profile data of the previous deposition layer.
