Abstract : Research activities concerning chemical behaviour of single- and bi-crystals under oxidizing and reducing conditions are summarized. They are (1) behavior of Sn single- and bi-crystal surfaces under controlled oxidizing conditions; decoration of Sn single- and bi-crystal surfaces by pure Zn or Cd, from vapour phase; (3) Ge single-crystal surfaces under controlled oxidizing conditions; (4) decoration of single- and bi-crystal surfaces by organic substances; (5) controlled etching of single-crystal; (6) new devices. (7) penetration of a liquid metal or alloy along the grain boundary of a bi-crystal; and (8) review of research in the field of controlled reduction of oxide crystals. (Author)
