A mobile, modular, cleanroom facility is made from one or more pre-assembled modules, transportable in their pre-assembled form. Each pre-assembled module includes an air filtration system including a ceiling plenum for providing clean air to the interior of the module. The air filtration system provides air cleaned to at least an ISO 8 classification. When the mobile, modular cleanroom facility is made of two or more modules, each of the modules is pre-assembled, and is transportable in its pre-assembled form. Each of the modules also includes an air filtrations system having a ceiling plenum for providing clean air to the interior of the module. Most preferably, the modules are connected by a connection assembly effective for providing a seamless transition from one module to the other while maintaining the appropriate clean air classification in the transition space.

An improved, user-friendly silane / silica sol copolymer hardcoating composition for protecting optical plastic and other substrates (including wood, metals, glass, plastics and most coated articles) from scratching is able to be manufactured at lower costs and to provide much-improved ease of use in transportation, storage, dipbath (or other coating tank) stability, and blush resistance in ordinary cleanroom atmospheres. The silane / silica sol copolymer is formed as a direct reaction product of an acidic silica sol and monomethyltrialkoxysilane, preferably substantially monomethyltriethoxysilane, in ratios of 30:70 to 70:30, most preferably about 40:60. A tail solvent aids blush resistance, reduces internal stress and permits adhesion to unprimed polycarbonate. Optionally, colloidal silica sol dissolved in water-miscible solvent may be reacted in a second stage with acidic aqueous colloidal silica sol earlier silanized with monomethyltrialkoxysilane.

A pillar-nanoantenna array structure is fabricated with a substrate to which pairs of pillars are coupled, where the pillars are characterized either by a thermal conductance less than 0.1 μW / deg or by transparency and a height exceeding thickness by at least a factor of two. Metallic caps atop a neighboring pair of pillars are separated by no more than 50 nm. An image-capture structure may be formed by modifying reflectance of a portion of the structure by heating of the portion by electromagnetic radiation. The array may be plastically deformed by raster scanning an electron beam across the array, exciting plasmon modes in the conducting particles thereby inducing a gradient force between neighboring conducting particles, and deforming neighboring pillars in such a manner as to vary the spacing separating neighboring conducting particles. A technique of plasmon-assisted etching provides for fabricating specified planar pattern of metal outside a cleanroom environment.

A system for managing cleanroom resources by providing a number of critical features in an integrated, low-cost package is described.

A refrigeration based air handling system design process for significant energy and cost savings in cleanroom and other applications requiring large air change rates is presented. The process utilizes a by pass around the air conditioning system, the ratio of bypass to air conditioning flow being such that minimal or no reheat of the air is required for applications having relative humidity (RH) control requirements and with RH control being achieved via cooling. If dehumidification is achieved by adsorptive processes, then the by pass ratio is varied so as to minimize cooling of the heated dry air. In other non relative humidity control applications the bypass is varied to minimize the air conditioning flow, thereby decreasing cost, but by using optimum cooling coil velocities in a manner such that system energy for airflow is minimized. The energy and cost savings achieved by this process vary between 65% to 15% depending on the Class of the cleanroom and / or on the number of air changes per hour required.

A rapidly deployable cleanroom is constructed from multiple modular building sections that are side-by-side and have similarly sized lengths, as well as user-accessible panels in multiple of them for air, water, power, networking, and other utilities at a similar internal location along their lengths. The utility panels can be standardized such that each panel is substantially identical to one another. The modular building sections can be drawn together using tension cables within lateral hollow extruded structural tubes beneath and / or above the cleanroom, the tension system utilizing jackscrews to pull everything tight. Because the utility panels are at the same longitudinal location in the building sections, the joined structure and resulting open space “ballroom” style cleanroom has the utility panels aligned with each other inside the cleanroom.
