1. Effects of surface plasmons in subwavelength metallic structures
Sammanfattning : The study of optical phenomena related to the strong electromagnetic response of noble metals (silver (Ag) and gold (Au) being most popular) over the last couple of decades has led to the emergence of a fast growing research area called plasmonics named after 'surface plasmons' which are electron density waves that propagate along the interface of a metal and a dielectric medium. Surface plasmons are formed by the coupling of light to the electrons on the metal surface subject to the fulfillment of certain physical conditions and they are bound to the metal surface. LÄS MER
2. Pathogen colonisation, transmission and infection control measures in burn patients
Sammanfattning : Burn patients are susceptible to infections due to impaired natural defences when the epidermal barrier is damaged. Moreover, the trauma affects the patient's immune system through local and systemic inflammatory reactions. Adding to that, the need for intensive care treatment with multiple surgical interventions increases the risk of infection. LÄS MER
3. Mechanical behaviour of carbon nanostructures
Sammanfattning : AbstractCarbon nanotubes (CNTs) have extraordinary mechanical and electrical properties. Together with their small dimensions and low density, they are attractive candidates for building blocks in future nanoelectromechanical systems and for many other applications. LÄS MER
4. The influence of crystallinity on the properties of carbon nanotubes
Sammanfattning : Carbon nanotubes have been advertised as a material with quite extraordinary properties, both mechanically and electrically. The truth is that carbon nanotubes is not one material, but several different. LÄS MER
5. Opening New Radio Windows and Bending Twisted Beams
Sammanfattning : In ground based high frequency (HF) radio pumping experiments, absorption of ordinary (O) mode pump waves energises the ionospheric plasma, producing optical emissions and other effects. Pump-induced or natural kilometre-scale field-aligned density depletions are believed to play a role in self-focussing phenomena such as the magnetic zenith (MZ) effect, i. LÄS MER
