Dr Gilberto Brambilla of the Optoelectronics Research Centre at Southampton University,UK,with a laboratory specimen of the nanowire he has developed using 250 micron optical fibre. The transitional 'shoulder' where the fibre has been 'pulled' to a much smaller diameter can be seen. This development is producing highly flexible silica fibres of less than 500nm diameter which have a very high tensile strength combined with a low weight. It has been found that,uniquely,the fibres' strength increases as the diameter decreases. These glass nano-wires are expected to have important applications within composite materials used in,for instance,aircraft technology and other fields where the unique weight to strength properties combined with a high degree of flexibility are important | |
