Conferences & Talks

In the framework of WP2, Cláudia Coelho illustrates the fabrication process and the first characterization results of REMAP’s current line setup designed to manipulate magnetorheological electrolytes at the microscale.

In the framework of WP3, Maria De Lourdes Gozalez Juarez explains the need of adapting growth conditions when fabricating on the micro-scale to achieve operating CIGSe micro-solar cells at the e-MRS. The design of the pattern and the SiO2 matrix play important roles in the synthesis process of micro-concentrators. For instance, the height of the SiO2 matrix helps shaping the CIGSe absorber, whereas the diameter of the micro-dots has an influence in the formation mechanism. On the other hand, the Se partial pressure and the annealing temperature have paramount influence in determining the morphology and optoelectronic performance of the CIGSe based micro solar cells.

In the framework of WP1, Nikolaos Ntallis has presented a study on ferrite nanoparticles covered with organic surfactants and showed the change of the magnetic behaviour of the nanoparticles, in the presence of the organic coating. The study demonstrated that with the choice of the proper type of the ferrite nanoparticles and surfactant, enhanced magnetic moment can be obtained for a better response in the magnetic field than the uncovered ones.

Marianna Vasilakaki presented the study on the magnetic behaviour of ultra-small Mn ferrite nanoparticles entrapped in bovine serum albumin, an environmentally friendly surfactant. Interestingly, the results show that this ligand binding to nanoparticles’ surface modifies their magnetization and anisotropy. In addition, the albumin coating process generates a change in the size and shape distribution of clusters of the exchange coupled particles affecting their thermal stability. This work suggests that optimization of the magnetic properties of nanoparticles’ assemblies can be succeeded by properly selecting not only the organic coating but also the coating procedure.
