Improved material processing of single BiO layered 1212 raises Tc to 102K with a superconducting volu~ne fraction around 30-50% and a critical current density of 2x106 Acre "2 (5K, 0T). Moreover, strong indications for the existence of Bi-1223 are present. Bi-0212 is realized for the first time in t
