Random close packing or jamming of spheres in a container

Scientists at the theoretical institutes, Chinese Academy of Science and Cybermedia Center at Osaka University performed extensive computer simulations to generate and examine random packing of spheres. They show that the ...

1D model helps clarify implosion performance at NIF

In inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF), a spherical shell of deuterium-tritium fuel is imploded in an attempt to reach the conditions needed for fusion, self-heating and eventual ...

Record high values of peak power with picosecond generators

Powerful picosecond generators are in demand in various fields of experimental electrophysics to produce ultrashort electron beams and X-ray pulses in vacuum diodes and to form runaway electron flows in gases.

Meteorite strikes may create unexpected form of silica

When a meteorite hurtles through the atmosphere and crashes to Earth, how does its violent impact alter the minerals found at the landing site? What can the short-lived chemical phases created by these extreme impacts teach ...
