FRANCISCO JAVIER BONILLA

Presentation

Dr. Francisco Bonilla is a Colombian scientist with a bachelor degree in physics and engineering. On 2013, he received his PhD in physics and chemistry of nanomaterials from the University Pierre et Marie Curie (UPMC Paris 6), France. During his career with experiences at different research centers in Spain, United States, France and Colombia, Dr. Bonilla has specialized on the characterization by electron microscopies, the synthesis of nanoparticles and the study of the correlation between the crystal structure and physical properties of materials for energy and information storing.

For his PhD the Institut des Nanosciences de Paris (INSP), Dr. Bonilla focused on the synthesis of self-assembled ferromagnetic nanowires by the pulsed laser deposition (PLD) technique. During this research, Dr. Bonilla has specialized in characterization techniques such as transmission electron microscopy (TEM), X-ray diffraction (XRD), SQUID and PPMS magnetometries and micromagnetic simulation of nanoparticles. By combining these techniques, Dr. Bonilla has determined the correlation between the morphology, the microstructure and the magnetic properties of the nanofibers, allowing him to establish a way to optimize the storage of magnetic information by varying the microstructure of the nanomaterials.

From 2014 to 2015, Dr. Bonilla worked as a postdoctoral researcher in the Laboratoire de physique et chimie de nano-objets (LPCNO), Toulouse, Fr. With the aim of understanding the magnetic results obtained from electron holography (EH-TEM) experiments on ferromagnetic nanocubes, Dr. Bonilla has carried out the micromagnetic simulations by using the open code program OOMMF. Thus Dr. Bonilla has been able to study the magnetic properties of nanocubes and their correlation with the crystal structure by means of an advanced electron microscopy technique, unique in France.

In 2016, Dr. Bonilla joint the electron microscopy platform at CIC energiGUNE as a postdoctoral researcher. Since 2017, he has been responsible of the platform giving service to all the research groups and external partners of CIC energiGUNE. During this time, Dr. Bonilla has focused on the characterization of materials for energy storage (such as batteries and super-capacitors) and thermal storage systems by using different electron microscopy techniques such as SEM, TEM, electron diffraction, FIB, in-situ TEM, among others. Dr. Bonilla has been involved in national funding projects as EKIZIEN (2017-2018) and he has been granted with the Jose Castillejo fellowship (2018) allowing him to do a stay at the Oak Ridge National Laboratory (ORNL), Tennessee, US, to carry out electrochemical in situ TEM experiments in micro-batteries of Na-O2.
