Nanotechnology in the Security Systems

Yalta workshop focused on several open problems in include the current state of nanotechnology and security problems. Recent advances in nanoscience have demonstrated that fundamentally new physical phenomena arise when systems are reduced in size down to dimensions comparable with the fundamental microscopic length scales of investigated materials. There have been many significant advances in the past two years since the last workshop and some entirely new directions of research in these fields have been undertaken. The programme of the workshop allowed presentations and opened discussions on several emerging modern research topics, such as new nano materials and sensors. Theoretical advances were tested against major experimental and technological achievements in related materials. There was intensive discussion in the field of nanotechologies and safety systems that include nanosensors, nanocomposite multifunctional coatings for safety systems, bio-nanosensors, and nanoanalyzers. In the session on nanomaterials the physical properties of graphene, carbon nanotubes, new composite materials, and spintronics were presented. Latest developments in nanotechnology and measurement techniques facilitate the detection of explosives. The most promising new materials and experimental techniques for the detection of hazardous materials including explosives are: carbon nanotubes, Josephson junctions, NMR techniques, and the determination of electronic nose . Participants benefitted from presentations of new methods for the detection of CBRN agents using chemical and biochemical sensors. The contemporary open problems of the physics of sensors include: the determination of sizes of nanoparticles, identification of particles, and determination of concentration and mobility of nanoparticles.§
