Latest Science News -- ScienceDaily - Hace 2 horas
For decades, scientists have agreed that comets are mostly water ice, but what kind of ice -- amorphous or crystalline -- is still up for debate. Looking at data obtained by ESA's Rosetta spacecraft in the atmosphere, or coma, around comet 67P/Churyumov-Gerasimenko, scientists are seeing evidence of a crystalline form of ice called clathrates.

Quantum dots enhance light-to-current conversion in layered semiconductors
Latest Science News -- ScienceDaily - Hace 2 horas
Scientists combined the excellent light-harvesting properties of quantum dots with the tunable electrical conductivity of a layered tin disulfide semiconductor to produce a hybrid material that exhibited enhanced light-harvesting and energy transfer properties. The research paves the way for using these materials in optoelectronic applications such as energy-harvesting photovoltaics, light sensors, and light emitting diodes (LEDs).
Curiosity leads us to seek out unpleasant, painful outcomes
