Abstract: A method to form a three-dimensional photonic crystal template with a gradient structure involves irradiating a photoresist composition of a thickness of at least 15 ?m from at least four laser beams to yield a periodic patterned with a percolating matrix of mass in constructive volumes of a cured photoresist composition and destructive volumes of voids free of condensed matter where the proportion of constructive volume displays a gradient from the irradiated surface to the substrate after development. For a given light intensity, photoinitiator concentration in the photoresist composition, and a given thickness, by irradiating for a relatively short period, a three-dimensional photonic crystal template displaying a gradient having greater constructive volume proximal the air interface forms and a relatively long irradiation period results in a gradient having greater constructive volume proximal the substrate.

Abstract: A method to strengthen or repair concrete and other structures comprises securing a plate having a shape memory alloy (SMA) wire embedded therein to a localized region of a structure. The SMA wire has a deformed shape configured for self-anchorage within the plate. The SMA wire is heated at or above an austenite transformation temperature, and the SMA wire resists shape recovery and remains self-anchored within the plate. Accordingly, a compressive force is generated within the SMA wire and transferred to the plate. At an interface between the plate and the localized region of the structure, the compressive force is transmitted from the plate to the structure, thereby providing localized prestressing of the structure.
