    摘要： Exemplary compositions and methods for reducing hexavalent chromium in cementitious compositions involve the use of a liquid additive composition, comprising stannous chloride. Along with the stannous chloride may be used at least one co-additive comprising an antioxidant, oxygen scavenger, or mixture thereof, and/or at least one agent comprising a cement grinding aid, cement quality improver, or mixture thereof.

    摘要： A fiber-based reflective lighting device and a lighting device. The fiber-based reflective lighting device includes a source configured to generate a primary light, a mat of reflective fibers which diffusely reflects light upon illumination with at least the primary light, and a light exit configured to emanate the reflected light. The lighting device includes a housing, a source configured to generate primary light and direct the primary light into the housing, a reflective mat of fibers disposed inside the housing at a position to reflect the primary light, and a light exit in the housing configured to emanate the reflected light from the housing.

    摘要： Methods and apparatus are presented to release stiction between suspended structures and the underlying surface in freestanding MEMS structures. A nanosecond rise time stress wave is launched on the backside of the Si substrate by impinging a 2.5 ns-duration Nd:YAG laser pulse onto a 3 mm-dia area. The compressive stress wave propagates through the Si substrate and arrives at the site of several stiction-failed cantilevers on the front Si surface. The compressive stress wave propagates through the cantilevered structures and is reflected into a tensile wave from their free surfaces. The returning tensile wave pries off the interface, releasing the cantilevers.
