Research pinpoints promise of polycrystalline perovskites

A team of scientists from the Energy Department's National Renewable Energy Laboratory (NREL) determined that surface recombination limits the performance of polycrystalline perovskite solar cells.

New method improves accuracy of imaging systems

New research provides scientists looking at single molecules or into deep space a more accurate way to analyze imaging data captured by microscopes, telescopes and other devices.

How GPS keeps up with a continent in constant motion

Nothing on the Earth's solid surface is static because all land is moving very slowly due to continental drift. This very slow movement affects everything around you in the same way so you can't tell it is happening, unless ...

Bakar Fellow: Aiding cells' strategy to survive

As any human biology text will tell you, enzymes in the stomach and intestine break down proteins that are locked into almost every bite we eat. The proteins' amino acid building blocks are then transported to the body's ...

High-pressure natural gas turbine-generator

Scientists of Peter the Great St. Petersburg Polytechnic University (SPbPU) have developed a turbo expander electric generator operating on high-pressure natural gas. Natural gas, compressed at the power station, releases ...

Image: Shedding star AG Carinae

This luminous star, AG Carinae, is losing mass at a phenomenal rate. Its powerful winds reach up to seven million km/hour, and exert enormous pressure on the clouds of material already expelled by the star.
