If you leave a clear bottle of water in the sunlight, the ultraviolet rays will kill any harmful microbes in that water, making it drinkable … but it has to sit in the sun for at least six hours. A ...

Cornell scientists have discovered a potentially transformative approach to manufacturing one of the world's most widely used ...

In the future, we could fuel the world with sunlight and water – using sunlight to derive hydrogen fuel from H2O. Currently, most hydrogen that’s used as feedstock and fuel is derived from natural gas ...

Using nothing but sunlight and photocatalysts, a 100 square meter (1,076 square foot) reactor produced carbon-free hydrogen for three years, demonstrating the potential of the concept. The approach is ...

Scientists in Japan have demonstrated a new proof-of-concept reactor that can harvest renewable hydrogen fuel from sunlight and water. The new 1,076-square-foot (100 square meters) reactor uses ...

Our atmosphere holds six times more water than you’ll find in all the rivers on Earth. The dew drops you see on grass and water droplets on a cold juice bottle are evidence of this natural reservoir ...

Ammonia is a chemical essential to many agricultural and industrial processes, but it's mode of production comes with an incredibly high energy cost. Various attempts have, and are, being made to ...

This may be hard to swallow, but the drinking bottle that you are dutifully carrying around with you all day to stay properly hydrated may be delivering more than water into your body. The most ...

Propane dehydrogenation (PDH) reaction is a highly endothermic reaction, typically requiring temperature above 600°C in conventional thermo-catalysis. However, elevated temperatures lead to ...

Earth is about 71 percent water. An overwhelming 97 percent of that water is found in the oceans, leaving us with only 3 percent in the form of freshwater—and much of that is frozen in the form of ...
