摘要: A composition of matter having a coated silicon substrate with multiple alternating layers of polydopamine and polyallylamine bound copper-indium-gallium oxide (CIGO) nanoparticles on the substrate. A related composition of matter having polyallylamine bound to CIGO nanoparticles to form PAH-coated CIGO nanoparticles. A related CIGO thin film made via conversion of layer-by-layer assembled CIGO nanoparticles and polyelectrolytes. CIGO nanoparticles are created via a flame-spray pyrolysis method using metal nitrate precursors, subsequently coated with polyallylamine (PAH), and dispersed in aqueous solution. Multilayer films are assembled by alternately dipping a substrate into a solution of either polydopamine or polystyrenesulfonate and then in the CIGO-PAH dispersion to fabricate CIGO films as thick as 1-2 microns.

摘要: The present invention provides a method for making a high strength, small grain size ceramic having a transgranular fracture mode by rapid densification of a green body and subsequent cooling of the densified ceramic. The ceramic may include dislocations, defects, dopants, and/or secondary phases that are formed as a result of the process and resulting in stress fields capable of redirecting or arresting cracks within the material. This ceramic can maintain transparency from ultraviolet to mid-wave infrared.

摘要: Methods for producing nanostructured, hydrophobic, superhydrophobic, or hydrophilic, transmissive, anti-reflective surfaces are described. The method for providing a hydrophilic surface includes steps of providing a substrate that is transmissive at at least one wavelength in the infrared to ultraviolet range of the electromagnetic spectrum and comprises at least one surface including nanostructures of a size smaller than the at least one wavelength; and functionalizing the at least one surface with hydroxyl groups thereon. A hydrophobic or superhydrophobic surface can be provided by contacting the at least one surface with a hydrophobic fluoropolymer for a time sufficient to apply at least a monolayer of fluorine-containing material to the at least one surface. These methods provide devices having excellent transmittance and anti-reflectance properties and which are resistant to seawater.

摘要: A transparent composite armor is made of tens to hundreds or even thousands of thin layers of material each with a thickness of 10-500 μm. An appropriate amount of impedance mismatch between the layers causes some reflection at each interface but limit the amplitude of the resulting tensile wave below the tensile strength of the constituent materials. The result is an improvement in ballistic performance and that will result is a significant impact in reducing size, weight, and volume of the armor.
