Lead-free solders based on Bi-Sn bimetallic nanoclusters with eutectic composition (Bi43Sn57) were synthesized at low temperature by simultaneous reduction reaction from aqueous solution containing bismuth and tin chlorides, using potassium borohydride as a reducing agent. By the same processing route, pure bismuth and tin nanoparticles have...

CoFe2O4 nanoparticles (hDNPDi ∼ 6 nm), prepared by a thermal decomposition technique, have been investigated through the combined use of dc magnetization measurements, neutron diffraction, and 57Fe Mossbauer spectrometry under high applied magnetic field. Despite the small particle size, the value of saturation magnetization at 300 K (Ms ∼=70 A...
