Owing to its topological properties and band collapse, Floquet helical photonic lattices have gained increasing attention as a purely classical setting to realize the optical analogues of a wide variety of quantum phenomena.We demonstrate both theoretically and numerically that Bookmark light propagation in an appropriately designed helical superla
Mining sites are areas Security where mining and restoration coexist and are constantly changing.The vegetation condition can reflect the process of surface mining and restoration, while quantifying the impacts of different mining patterns and surrounding environments on vegetation is the key to balancing mining activities and ecological restoratio
We report a new type of alkaline-stable hollow-fiber reverse osmosis (RO) membrane with an outside-in configuration that was established via adsorption of positively charged poly(vinyl alcohol) copolymers containing a small amount of quaternary ammonium moieties.Anionic sulfonated poly(arylene ether sulfone nitrile) hollow-fiber membranes were util
