PGSB seminar on the Topic: Nanoparticle assemblies: Order by self-organization and collective magnetism

15 May, 2022

Palestine Academy for Science and Technology (PALAST) hosted Dr. Asmaa Qdemat, who is a postdoctoral fellow in the PGSB returner program and the speaker of the Nanoscience research cluster, the researcher at the Institute of Quantum Materials and Collective Phenomena (JCNS-2/PGI-4) at Jülich Research Center (Forschungszentrum Jülich FZJ) in Germany, under the direction of Prof. Dr. Thomas Brückel
The doctoral researcher led the seminar on the 15th of May 2022 at PALAST and online via Teams technology. The Seminar was attended by academics, researchers, and interested students from various Palestinian universities.

The postdoctoral researcher presented her research activity at (JCNS-2/PGI-4) titled “Nanoparticle assemblies: Order by self-organization and collective magnetism”. She presented the structural and magnetic correlations of highly ordered assemblies of magnetic and non-magnetic nanoparticles deposited on a surface. Supported by a multitude of experimental methods, among which scattering methods have played an essential role.

In her work, she introduced an improved variant of the drop casting method, she demonstrated the formation of large area highly ordered monolayers of silica nanoparticles on a silicon substrate. Also, she investigated structurally and magnetically 2D arrays of cobalt ferrite nanoparticles to determine the effect of magnetostatic interactions on the magnetic ordering. Also, she presented the deposition of iron-oxide cubic nanoparticles onto a trench-patterned silicon substrate in order to reach a 3D arrangement.

The researcher introduced the institute of Quantum Materials and Collective Phenomena: JCNS-2 in general and the group she works with in particular. She presented and introduced the PGSB cluster in Nanoscience, its long-term goal of supporting the research in Palestine. The researcher presented the current proposed MSc and Ph.D. topics within the PGSB 7th call.
