摘要： An apparatus, method, and system for post-processing a printed graphene ink pattern or other deposition on a substrate. A pulsed UV laser is tunable between various energy densities to selectively modify the printed ink or deposition in electrical or physical properties. In one example, radical improvements in electrical conductivity are achieved. In another example, controlled transformation from essentially 2D printed or deposited graphene to surface topology of 3D nanostructures are achieved. The 3D structures are beneficial in such applications as electrochemical sensors of different types and characteristics. In another example, hydrophobicity of the printed or deposited graphene can be manipulated starting from a hydrophilic to super hydrophobic surface.

摘要： Methods of forming porous nano-scale or micro-scale structured materials and structured materials formed thereby. Such methods entail providing a donor material and reacting the donor material to form a compound that deposits on a surface of a substrate to produce nano-scale or micro-scale geometric features of the structured material. In particular embodiments, the donor material is in a solution and the reacting step is performed by contacting the surface of the substrate with the solution and directing heat through the solution onto the surface to locally heat a portion of the solution in contact therewith.

摘要： Thin glass-like ceramic films which possess organic or physically functional structures with thicknesses in the 15 to 500 nm range and bottom-up methods for their fabrication are described. SiO2-rich structures having gradient properties are formed from a silsesquioxane having an electronegative β substituent and at least one organofunctional silane or at least one metal alkoxide.

摘要： A copper-based ink contains copper hydroxide and diethanolamine. The ink may be coated on a substrate and decomposed on the substrate to form a conductive copper coating on the substrate. The ink is low cost and micron-thick traces of the ink may be screen printed and thermally sintered in the presence of up to about 500 ppm of oxygen or photo-sintered in air to produce highly conductive copper features. Sintered copper traces produced from the ink have improved air stability compared to traces produced from other copper inks. Sintered copper traces having sheet resistivity of about 20 mΩ/□/mil or less may be obtained for 5-20 mil wide screen-printed lines with excellent resolution.

摘要： Flash Photo-Oxidation Device and Higher Order Structural Analysis is employed for higher order structural analysis of biomolecules. Biomolecular higher order structure (HOS) results from the confounded superimposition of a biomolecule's secondary, tertiary, and quaternary structure and defines the manner in which a biomolecule presents itself and interacts with other biomolecules in living systems. A rapidly growing class of therapeutic drugs, known as biotherapeutics, comprises a variety of proteins, whose therapeutic properties are inherently linked and dependent upon their HOS. As such, HOS analysis of biotherapeutics is an important analytical requirement in the biopharmaceutical industry. The present invention provides new means and methods for the determination of biopharmaceutical HOS and associated conformation using improved devices and methodologies for flash photo-oxidation of proteins to determine their higher order biomolecular structure, and such is responsive to the increased demand for new and improved HOS analytical means in the biopharmaceutical industry.

摘要： Embodiments of the invention include a method of initiating an optical fiber. In some embodiments, a distal portion of the optical fiber is coated with an energy absorbing material. In some embodiments, the material includes a metal flakes or powder dispersed in a solution of organic solvents. After the material dries, laser energy is fired through the optical fiber. The laser energy can be absorbed in the material and ignites the organic solvents. This combustion melts the material of the optical fiber, and impregnates the optical fiber with the metal flakes or powder of the material. The resulting optical fiber is thus permanently modified so that the energy applied through the fiber is partially absorbed and converted to heat.

摘要： A conductive nanowire film having a high aspect-ratio metal is described. The nanowire film is produced by inducing metal reduction in a concentrated surfactant solution containing metal precursor ions, a surfactant and a reducing agent. The metal nanostructures demonstrate utility in a great variety of applications.
