Abstract: A method of pulsed laser processing of solid surface for enhancing surface hydrophobicity is disclosed wherein the solid surface is covered with a transparent medium during laser processing and the laser beam incidents through the covering medium and irradiates the solid surface. Two effects are obtained simultaneously. One is the laser-induced texture formation directly under the laser irradiation. The other is the deposition of the laser-removed materials along the laser scan lines. Both effects introduce surface roughness on nanometer scales, and both enhance surface hydrophobicity, rendering superhydrophobicity on the surfaces of both the laser-irradiated solid and the covering medium. Because the beam scan line spacing can be larger than a single scan line width by multiple times, this method provides a high processing speed of square inch per minute and enables large area processing.

Abstract: At least one embodiment of the present invention provides preparation methods and compositions for nanoarchitectured multi-component materials based on carboncoated iron-molybdenum mixed oxide as the electrode material for energy storage devices. A sol-gel process containing soluble organics is a preferred method. The soluble organics could become a carbon coating for the mixed oxide after thermal decomposition. The existence of the carbon coating provides the mixed oxide with an advantage in cycling stability over the corresponding carbon-free mixed oxide. For the carbon-coated mixed oxide, a stable cycling stability at high charge/discharge rate (3A/g) can be obtained with Mo/Fe molar ratios ≥ 1/3. The cycling stability and rate capability could be tuned by incorporating a structural additive such as Al2O3 and a conductive additive such as carbon nanotubes. The high rate performance of the multi-component material has been demonstrated in a full device with porous carbons as the positive electrode material.

Abstract: A method of forming patterns on transparent substrates using a pulsed laser is disclosed. Various embodiments include an ultrashort pulsed laser, a substrate that is transparent to the laser wavelength, and a target plate. The laser beam is guided through the transparent substrate and focused on the target surface. The target material is ablated by the laser and is deposited on the opposite substrate surface. A pattern, for example a gray scale image, is formed by scanning the laser beam relative to the target. Variations of the laser beam scan speed and scan line density control the material deposition and change the optical properties of the deposited patterns, creating a visual effect of gray scale. In some embodiments patterns may be formed on a portion of a microelectronic device during a fabrication process. In some embodiments high repetition rate picoseconds and nanosecond sources are configured to produce the patterns.

Abstract: Methods, devices, and systems for ultrashort pulse laser processing of optically transparent materials are disclosed, with example applications in scribing, marking, welding, and joining. For example, ultrashort laser pulses create scribe features with one pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. Slightly modifying the ultrashort pulse laser processing conditions produces sub-surface marks. When properly arranged, these marks are clearly visible with correctly aligned illumination. Reflective marks may also be formed with control of laser parameters. A transparent material other than glass may be utilized. A method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. In some embodiments of transparent material processing, a multifocus beam generator simultaneously forms multiple beam waists spaced depthwise relative to the transparent material, thereby increasing processing speed.
