Antarctic snow on sea ice can contain slush, snow ice, and stratified layers, complicating satellite retrieval processes for snow depth, ice thickness, and sea ice concentration. The presence of moist and brine-wetted snow alters microwave snow emiss

Submicrometer MnxCoFe2−xO4(0 ≤x< 1) spinel particles with a spherical shape were prepared at low temperature from oxalic precursors. Because of their small crystallite size (about 50 nm), these ferrite particles can be oxidized below 400°C givin
