Using density-functional tight-binding theory we demonstrate that silicon-based tubular nanostructures in the form of siloxenes are stable and energetically viable. The structures studied here have a semiconducting gap which is independent of the chirality, but showing an increase of the gap size wi

β¦ Synopsis
In conjunction with its 1984 Annual Assembly, to be held in Boston (U.S.A.) from 16 to 21 July, the International Institute of Welding (IIW) is organising a two-day Conference on the welding of tubular structures. This will comprise the 1984 Houdremont
Lecture "Connections for welded tubular structures" by P. W. Marshall (U.S.A.) and three sessions devoted respectively to applications, fabrication and design and research. It is expected that some 50 papers will be presented and discussed at these three sessions.
