Ebook "Calculations on nonlinear optical properties for large systems: The elongation method" describes the quantum-mechanical treatment of the response to one or more external oscillating electric fields for molecular and macroscopic, crystalline systems. To calculate NLO properties of large systems, a linear scaling generalized elongation method for the efficient and accurate calculation is introduced.

"Zinc-doped silicene nanoribbons under the influence of constant electric field: A DFT study" investigates the structural and electrical properties of SNRs when doped with zinc. In addition, the system is placed in a constant external electric field. Research shows that the top configuration is the most stable configuration in the external electric field. The research creates a premise for applications in controlling the properties of materials by doping and external electric field effects.

"Structural and electrical properties of germanene nanoribbons doped with boron - A DFT study" using density functional theory (DFT) and VASP software, the formation energies, energy band structures, and density of states of the configurations are studied. The configuration for the smallest formation energy is the most optimal configuration, so this configuration is the most stable. The appearance of an external electric field changes the band gap and the energy band structure of the system.

Improvement of the optical absorption coefficient is essential to enhance the light conversion efficiency of thin-film organic solar cells. Here we report the use of an external electric field as a novel switch to improve the optical absorption capacity of two-dimensional defect blue phosphorene (BlueP) systems.

The sensing of individual molecules as they pass through nanopores under an external field is a popular research field. The approach is simply based on the detectable temporary blockades in the ionic current as the molecules pass through the nanopores. These signatures of the current have been shown to be a function of nanoparticle and nanopore size and geometry as well as the external electric field. However, models developed in this context fail to predict the experimentally observed behavior in technologically important shorter nanopores.

The Hall effect is studied theoretically in a doped semiconductor superlattice (DSSL) subjected to a crossed dc electric field and magnetic field in the presence of an intense electromagnetic wave (EMW). By using the quantum kinetic equation for electrons interacting with acoustic phonons at low temperature, we obtain expressions for the magnetoresistance as well as the Hall coefficient in dependence on the external fields and characteristic parameters of the DSSL. Analytical results are numerically evaluated for the GaAs:Si/GaAs:Be DSSL.

Today, research and technology play a decisive role for the European food sector for the development of new products as well as for improved safety measures. In July 2000, DG RTD requested a study on potential future European research priorities in food technology and food safety from the Institute for Prospective Technological Studies (IPTS), Joint Research Centre. The study design comprised the involvement of external expertise from industry as well as from academia: The results of the study were derived from two experts workshops held in Sevilla at the IPTS in December 2000 and May 2001.
