• Eliminating emissions in India and China could add years to people's lives

  17-10-2018 23:28
  In a recent study, researchers wanted to know how replacing coal-fired powerplants in China and India with clean, renewable energy could benefit human health and save lives in the future. The researchers found that eliminating harmful emissions from powerplants could save an estimated annual 15 million years of life in China and 11 million years of life in India.

• Taking steps toward a wearable artificial kidney

  17-10-2018 17:10
  There just aren't enough kidney transplants available for the millions of people with renal failure. Aside from a transplant, the only alternative for patients is to undergo regular dialysis sessions to clear harmful cellular waste from their bodies. Now, scientists report a new urea sorbent that could accelerate progress toward the development of a lightweight, wearable artificial kidney with the potential to make dialysis more convenient, comfortable and effective.

• Controlling organic semiconductor band gaps by electron-acceptor fluorination

  17-10-2018 14:08
  Researchers synthesized a fluorinated electron-acceptor for use in organic semiconductors. The high electronegativity of the fluorine substituents enhanced the electron-accepting properties of the widely used electron-acceptor. The power conversion efficiency of a thin film solar cell based on the fluorinated product was shown to be significantly higher than that of a cell containing an unmodified analogue. The synthesized material could be applied in thin film organic solar cell devices.
