Bismuth oxide-based solid oxide fuel cells (SOFCs) represent a promising technology for clean energy conversion, utilising the exceptional ionic conductivity of δ-Bi₂O₃. The unique crystal structure ...
Single crystals of the multiferroic material bismuth-iron-oxide. The bismuth atoms (blue) form a cubic lattice with oxygen atoms (yellow) at each face of the cube and an iron atom (gray) near the ...
Domain walls that conduct electricity, mere billionths of a meter wide, could be the ultimate nanoscale feature for future electronics. Scientists have not only discovered conducting domain walls -- ...
