Life would cease to exist. This property of water, though, means it also transports and disperses toxins just as easily, including radioactive materials. Cleanup around nuclear sites, such as the recent disaster at the Fukushima Daiichi nuclear power […]

She looked at two photocatalysts and tested whether they can accelerate the UV-decontamination power of sunlight. In particular, she studied titanium dioxide […]
