International Speciality Chemicals, working in close collaboration with the UK University of Durham and based on technology developed originally by Prof. Ryan. Z. Tian of the US University of Arkansas, developed a new generation of titanium nanowires with exciting new properties.


These ultra-light ceramic nanowires are capable of withstanding very high temperatures and when used in applications of filtration, have been demonstrated to have properties way beyond the current performance levels of existing filtration media. Experiments have shown their ability to remove bacteria / virus DNA / spores for air of liquid streams, opening up a new era of ultra-filtration, never before imagined.

Due to the size of the nanowires, the surface area available for filtration / absorption is huge and given the inherent high temperature stability of several hundred degree celcius, filters made from this new material can easily be cleaned to enhance operating lifetime. Furthermore, a special coating can be applied that enhances the UV photo-catalysis effect allowing self-cleaning on exposure to UV light.

Nanowires cast in Disc Form

The ceramic nanowires can be easily formed into a paper-like substance and moulded into a variety of shapes and sizes.


In the paper-like form this material can be used for ultra-light flame barriers for aircraft etc. where high performance and low weight are pre-requisites.


Nano-technology is still in its' infancy and new applications are being discovered all the time. The physical and chemical changes that takes place at this minute level is opening doors to solutions to old problems and there is no doubt that many of the technical barriers of the past will look to 21st century nanofibres for the solution
