A new study finds inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking water supplies. The approach should be efficient and economic, even down to part-per-billion levels of contamination.

Perovskites are a category of materials with a distinct crystalline atomic structure. Just over ten years ago, scientists found that perovskites are exceptionally good at absorbing light. The discovery set off an overwhelming flow of new research into perovskite solar cells. Since then, the efficiency of those solar cells has increased substantially and now rivals that of conventional silicon cells.
In manufacturing, perovskite cells are superior because they’re much more effortless and require less energy consumption. The light absorber can be made at near room temperature, whereas silicon needs to reach 2,700 degrees Fahrenheit. Perovskite films are also much thinner than silicon wafers (400x thinner), opening up more opportunities for its use and requiring less material overall, making for a potentially cheaper device. However, the stability and reliability of the perovskite cells remain a challenge.

In a relatively short space of time, perovskite solar cells have become a highly promising candidate when it comes to how we might generate electricity in the future, but there are some design problems to overcome first. These largely relate to stability issues that see the cells quickly deteriorating during use, but scientists at Brown University have come up with a way of addressing this by targeting a weak point with something they call molecular glue.
