The dye molecules themselves are bound to tiny particles of titanium dioxide, a less-famous (but cheaper) semiconductor than silicon, and the whole assembly is immersed in an electrolyte and sandwiched between two electrodes.
染料分子自身会与二化钛(一种不如硅名气大,但比硅便宜半导体)细小微粒相结合,然后整个装置会浸没于一种电解质里并夹于两个电极之间。
Crucially, in that gel were plenty of thioketals, compounds that fall apart when exposed to reactive, oxygen-containing molecules, plus just a sprinkle of titanium dioxide--an inert material that, when exposed to ultrasound, releases just those molecules.
至关重要是,这种凝胶中含有大量硫酮化合物,这种化合物接触到活性含分子就会分解,外加少量二化钛--一种惰性物质,暴露在超声波时,这些分子就会被释放。
Material scientists are trying to replace glass lenses with something lighter and smaller based on " meta surfaces" or engineered materials In this meta-surface lens, tiny towers of titanium dioxide are arranged in a specific pattern to focus light.
材料科学家正试图用基于“元”或工程材料更轻、更小东西代替玻璃透镜。在这种元透镜中,微小二化钛塔以特定图案排列以聚焦光线。
