6. Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design
Abstract : Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the ~10 MeV regime. READ MORE

7. Contributions to Emission, Exposure and Risk Assessment of Nanomaterials
Abstract : In recent years, synthetic nanomaterials have begun to be produced and used in increasingly larger volumes. These materials may cause new or increased risks to the environment, but no harmonized methods for structured assessment of their environmental risks exist. READ MORE

8. The Character of the Particle Emissions from Possible Future Marine Fuels in SOx ECAs
Abstract : Particles in the ambient air come from both natural and anthropogenic sources. One anthropogenic source is combustion of fossil fuels. The awareness of these particles impact on human health and climate has increased the interest for the particle emissions from e.g. READ MORE

9. Photospheric emission from structured, relativistic jets : applications to gamma-ray burst spectra and polarization
Abstract : The radiative mechanism responsible for the prompt gamma-ray burst (GRB) emission remains elusive. For the last decade, optically thin synchrotron emission from shocks internal to the GRB jet appeared to be the most plausible explanation. READ MORE

10. Modeling of Radio Emission from Supernovae : Application to Type Ia
Abstract : The interaction of supernova (SN) ejecta with the circumstellar medium (CSM) drives a strong shock wave into the CSM. These shocks are ideal places where effective particle acceleration and magnetic field amplification can take place. READ MORE
