摘要： The invention disclosed herein provides highly efficient methods and materials useful for surface patterning via polymerization reactions. In particular, by using a light-mediated radical polymerization procedure, brush formation from a surface can be regulated spatially by controlling the area of irradiation. In embodiments of the invention, polymer chain length (and/or film thickness) can be effectively controlled by either the amount of time a surface is irradiated with light (temporal control) or by the intensity of light allowed to reach the surface. Such light-mediated control allows artisans to use the disclosed processes to form complex 3-dimensional structures on a variety of surfaces. Moreover, the simplicity of the disclosed polymerization processes allows them to be adapted for use in a wide range of technologies.

摘要： Systems and methods for calibrating a solid-imaging system (10) are disclosed. A calibration plate (110) having a non-scattering surface (140) with a plurality (150) of light-scattering fiducial marks (156) in a periodic array is disposed in the solid-imaging system. The actinic laser beam (26) is scanned over the fiducial marks, and the scattered light (26S) is detected by a detector (130) residing above the calibration plate. A computer control system (30) is configured to control the steering of the light beam and to process the detector signals (SD) so as to measure actual center positions (xA, yA) of the fiducial marks and perform an interpolation that establishes a calibrated relationship between the angular positions of the mirrors and (x,y) locations at the build plane (23). The calibrated relationship is then used to steer the laser beam in forming a three-dimensional object (50).

摘要： The present invention relates to a method for preparation of an ultraviolet (UV)-curable inorganic-organic hybrid resin containing about or less than 4% volatiles and less than 30% organic residues. The UV-curable inorganic-organic hybrid resin obtained according to this method can be UV-cured within a markedly very short time and enables, upon curing, the formation of a transparent shrink- and crack-free glass-like product having high optical quality, high thermal stability and good bonding properties. In view of these properties, this hybrid resin can be used in various applications such as electro-optic, microelectronic, stereolithography and biophotonic applications.
