Optical neural networks implemented with Mach-Zehnder Interferometer (MZI) arrays are a promising solution to enable fast and energy-efficient machine learning inference, yet finding a practical ...

Multilayer Structures of Flexible Substrate/Graphene/Cu Foil Two methods were employed in preparing a multilayer flexible substrate/graphene/Cu foil: (1) lamination of the graphene/Cu foil with a ...

These extreme environmental conditions cause conventional coatings to crack or detach from the substrate. Their optical properties quickly deteriorate, which can result in disturbing double images.

Note: This telescope total efficiency is just calculated from the products of measured reflectivity of each mirror and not consider any vignetting in the optical ... in the vacuum chamber and coated ...

Powder coating is a wonderful way to apply a smooth, colored surface to a part, whether for aesthetic reasons or corrosion protection. Traditionally, powder is applied via a air gun that sprays it ...

An inside look into the Carmelite Monks of Wyoming, who are combining centuries-old Gothic architectural principles with modern CNC machining to build a monastery in the mountains of Wyoming.
