Fast heat flows in warm dense aluminum

Aug. 31, 2017 -  
Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas. In the warm dense matter (WDM) regime, experimental data are very...

Reducing reflectivity in solar cells and optics with micro- and nanoscale structures

Aug. 30, 2017 -  
When it comes to solar cells, less is more -- the less their surfaces reflect a sun’s rays, the more energy can be generated. A typical fix to the problem of reflectivity is an anti-reflective coating, but that might not always be the best solution, depending on the application. Lawrence Livermore...
