Metallic material systems play a key role in meeting the stringent weight and durability requirements for reusable launch vehicle (RLV) airframe hot structures. Gamma titanium aluminides (γTiAl) have been identified as high-payoff materials for high-temperature applications. The low density and good elevated temperature mechanical properties of γ-TiAl alloys make them attractive candidates for ...
The ability to pattern oxide structures at the microscale in both planar and three-dimensional forms is important for a broad range of emerging applications, including sensors, micro-fuel cells and batteries, photocatalysts, solar arrays, and photonic bandgap (PBG) materials. Here, we report the fabrication of micro-periodic oxide structures by direct-write assembly of sol-gel inks. Specificall...
Microlens arrays fabricated by a direct ink-jet printing of UVcurable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. Using this simple technique, we demonstrated periodic arrays of almost semi-spherical microlenses of 50 μm diameter size and a focal distance of 48μm. The optical characteristi...
Photopolymers are appealing materials for many optical applications. For most of them, shrinkage plays an important role in the final properties of the display, especially in holographic data storage applications. In this paper, we demonstrate that to quantify correctly the shrinkage, it is mandatory to measure the angle of propagation for both diffracted orders ± 1, so that an accurate value o...
