1. Adsorptive metal nanodots (especially silver) on molecular sieve surfaces for air and water purification - Certain molecular sieve surfaces template and stabilize the formation of metal nanodots. This is particularly true of silver on chabazite type surfaces and titanosilicates ETS-10 and ETS-2. These silver nanoparticulates have the ability to separate noble gases from air as well as reversibly complex mercury in flue gas streams such as coal fired power plants. Beyond these two applications, adsorption by zeolite supported silver nanodots is unexplored. We believe these materials may have the potential to strip all organics, including VOCs, from air streams as well as water. We also believe radon can be stripped from living space environments.

1. 吸附金属纳米点（特别是银）在分子筛表面用于空气和水净化-某些分子筛表面模板和稳定金属纳米点的形成。这一点在茶辉石型表面和钛硅酸盐ETS-10和ETS-2表面的银中尤为明显。这些银纳米颗粒具有从空气中分离稀有气体以及从燃煤电厂等烟气流中分离可逆复合汞的能力。除了这两种应用之外，沸石负载银纳米点的吸附尚未被探索。我们认为，这些材料可能有潜力从气流和水中去除所有有机物，包括挥发性有机化合物。我们还认为，氡可以从生活空间环境中去除。
