At the beginning of the seventies, a break-through took place in the telecommunication research. The introduction of Chemical Vapour Deposition technology in the manufacture of optical fibres allowed both technical quality and economical convenience to realise optical networks, thus beginning the telecommunication revolution. Since that moment, a great development of the CVD techniques has been...
Background and aims: Air pollution is one of the most important factors in conflict with environmental quality in many cities around the world that can have negative effects on human health. Emission control from industrial and domestic sources in line with the objectives of sustainable development is an important and challenging problem. Decision making with regard to various indices of social...

A chemical and water-free laser-assisted cleaning technology using deep ultraviolet photons in conjunction with a flowing inert gas is introduced. This environment friendly technology can be used in a wide-range of industrial applications.
Stemming from MEMS (MicroElectroMechanical System) developments, designs and fabrication technology, packaged microfluidic chips – used first for biological and chemical analysis (μTAS, Micro Total Analysis Systems) – were modified to perform chemical syntheses (1). In addition, chip devices for the mixing of miscible or immiscible fluids offered a novel means for the processing of this unit op...
