摘要： Natural materials often boast unusual combinations of stiffness, strength and toughness currently unmatched by today's engineering materials. Beneficially, according to the embodiments of the invention, these unusual combinations can be introduced into ceramics, glasses, and crystal materials, for example by the introduction of patterns of weaker interfaces with simple or intricate architectures. Two-dimensional surface modifications and three-dimensional arrays of effects within these materials allow for the deformation of these materials for increased flexure, impact resistance, etc. Further, the addition of interlocking substrate blocks in isolation or with additional flexible materials provide for improved energy dissipation and toughening. Such modified materials, based on carefully architectured interfaces, provide a new pathway to toughening hard and brittle materials.

摘要： The present disclosure concerns a mineralized tissue adhesive or filler composition comprising an intermolecular crosslinked osteopontin protein for treating an exposed surface of a mineralized tissue. The mineralized tissue adhesive or filler composition can be added directly on the exposed surface of the mineralized tissue or on a layer of monodisperse OPN protein which has been deposited on the exposed surface of the mineralized tissue. The present disclosure also includes methods and kits of using the mineralized tissue adhesive or filler composition especially in dental applications. The present application also provides dental coatings, fillings, bondings and veneers comprising the mineralized tissue adhesive or filler composition described herein.
