Congratulations Jan for your INPhINIT diploma!

3rd July 2018

Jan Grzelak attended the award ceremony from La Caixa Fellows in Caixa Forum (Barcelona) and received a diploma for his excellence fellowship supported by La Caixa to perform his PhD at the N&N group on the topic “Mesoporous magnetic nanorods for theranostics”. Two other ICMAB researchers have also been granted with by a PhD grant from La Caixa and also assisted the ceremony.

Congratualtions Jan!

Jan participated in the 1st Spanish Conference on Biomedical Applications of Nanomaterials

7th-8th of June 2018

Jan Grzelak, PhD student at the N&N group, travelled to Madrid to attend the 1st Spanish Conference on Biomedical Applications of Nanomaterials (SBAN) held at the Instituto de Ciencia de Materiales de Madrid (ICMM). Jan presented the poster “Mesoporous silica nanorods as theranostic platforms”.

Published paper about Jan’s work in Warsaw

Congratulations Jan! Today we announce that the previous work of the PhD student Jan Grzelak has been recently published on the journal Nanomaterials . This work is based on the Bachelor’s project he did in Warsaw under the supervision of Dr. Wiktor Lewandowski. 

 

Paper abstract: By coating plasmonic nanoparticles (NPs) with thermally responsive liquid crystals (LCs) it is possible to prepare reversibly reconfigurable plasmonic nanomaterials with prospective applications in optoelectronic devices. However, simple and versatile methods to precisely tailor properties of liquid-crystalline nanoparticles (LC NPs) are still required. Here, we report a new method for tuning structural properties of assemblies of nanoparticles grafted with a mixture of promesogenic and alkyl thiols, by varying design of the latter. As a model system, we used Ag and Au nanoparticles that were coated with three-ring promesogenic molecules and dodecanethiol ligand. These LC NPs self-assemble into switchable lamellar (Ag NPs) or tetragonal (Au NPs) aggregates, as determined with small angle X-ray diffraction and transmission electron microscopy. Reconfigurable assemblies of Au NPs with different unit cell symmetry (orthorombic) are formed if hexadecanethiol and 1H,1H,2H,2H-perfluorodecanethiol were used in the place of dodecanethiol; in the case of Ag NPs the use of 11-hydroxyundecanethiol promotes formation of a lamellar structure as in the reference system, although with substantially broader range of thermal stability (140 vs. 90 °C). Our results underline the importance of alkyl ligand functionalities in determining structural properties of liquid-crystalline nanoparticles, and, more generally, broaden the scope of synthetic tools available for tailoring properties of reversibly reconfigurable plasmonic nanomaterials

Jan defended his Master Thesis in Poland

 
Jan Grzelak defended his Master thesis at the University of Warsaw on the 27th of July 2017. His supervisors Anna Laromaine and Martí Gich came to Poland for the defence.
Jan was enrolled in a Master’s in Nanostructure Engineering and the title of the thesis was ‘Synthesis of supports for catalysis with palladium nanoparticles templated by bacterial cellulose’.
 
He got the highest mark (excellent) for the defence and the final mark from the whole studies was 4.88/5. He will receive a diploma with distinction! Next academic year Jan will be back to the N&N group to do his PhD with a grant from La Caixa
 

Congratulations Jan!

Jan Grzelak got a INPhINIT grant to do his Ph.D. thesis at the N&N group!

On the 30th of May 2017, we got very good news: Jan has secured a Ph.D. position at the N&N group! Jan obtained a doctoral fellowship from the INPhINIT program promoted by the La Caixa Foundation. The fellowship is awarded to 57 outstanding international students for Ph.D. studies in top Spanish research centres. He will do his Ph.D. thesis under the supervision of Anna Roig and Martí GichAll the members of the group congratulated Jan and did a toast with cava for him.
Jan Grzelak says:

 The project that I chose is ‘Mesoporous magnetic nanorods for theranostics’ offered by Anna Roig and Martí Gich.
I am extremely happy to continue doing research in the N&N group for the next 3 years! 

Congratulations Jan!

This same day, Mulling visited us in ICMAB. Mulling is a former Ph.D. student of the N&N group. She was the first one to work with bacterial cellulose.

We welcome Jan in the N&N group!

Jan Grzelak obtained a Bachelor’s degree in Nanostructure Engineering at the University of Warsaw (Poland). Then he started studying the Master program at the same university, also in Nanostructure Engineering. Now he is doing his second and last year of Master with an Erasmus program at the UAB, on Advanced Nanoscience and Nanotechnology

Jan will join our N&N group at ICMAB, and will be supervised by Martí Gich and Anna Laromaine. He will be working on alumina tubes with palladium nanoparticles, using bacterial cellulose as a template for the synthesis.

We hope you enjoy your stay with us, Jan!
