摘要： The invention encompasses compositions and methods for designing or producing three-dimensional articles layer-by-layer, whereby the specific approach to build-up a region of a single layer by fusion, deposition of material, or other path-based process or non-path process that creates track-like geometries requires either differing track or track-like geometry, or track or track-like geometry printing parameters, within a region of a single layer or within adjoining regions of multiple layers, is disclosed. Employing this method, single layer or multilayer parameter-varying fusing and deposition strategies can be generated that reduce article fabrication time and improve article physical properties, in part by targeting a distribution of scan paths that satisfy covering problem overlap and/or dense packing criteria. Additionally, methods and compositions for designing or producing three-dimensional articles by altering the thickness of a material layer deposited during a print relative to the slice thickness or net displacement of a stage or of a material and/or energy-depositing print head, are disclosed. Employing this method can result in the reduction of article fabrication time and/or the improvement of printed article physical properties, where these results advantageous to printing are dependent on the print process, material properties, and feedstock properties employed during the print.

摘要： Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability, and are readily applied in coating processes. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.

摘要： Nanocomposite silicon and carbon compositions. These compositions can be made from polymer derived ceramics, and in particular, polysilocarb precursors. The nanocomposite can have non-voids or be nano-void free and can form larger macro-structures and macro-composite structures. The nanocomposite can contain free carbon domains in an amorphous SiOC matrix.

摘要： A compound for protection of an object from a blast or shock wave. The compound include a matrix material and at least a first and second sets of inclusions in the matrix material that differ in size, quantity, shape and/or composition in a direction through the impact-absorbing material, the combination of which contributes to the ability of the material to exhibit at least one property that changes as the inclusions are deformed in response to a blast or shock wave.
