You won’t find ice cubes like this in your freezer.An international team of scientists has set a new record for creating ice crystals that have a near-perfect cubic arrangement of water molecules—a fo...
Microwave scattering from ice crystals: how much parameters can differ from equal volume spheres
Microwave scattering from ice crystals parameters equal volume spheres

The scattering properties of ice crystals at centimeter and millimeter wavelengths are fundamental for their measurement with radars or radiometers as well as for many other applications in remote sen...
Scanning electron microscopy and molecular dynamics of surfaces of growing and ablating hexagonal ice crystals
