Exner Lectures 2024 – Vienna, Austria

MAY 2024

Christine, Seungho and Tobias attended the Exner Lectures in Vienna where they presented their recent publications on posters. Christine was awarded the Pioneering Milestone Award in the category “PhD/Postdoc” for her work in unveiling the chemistry that occurs during solution processing.  While the concept of the purification process may seem obvious (where particles are washed to make the material pure), this does not work when impurities are electrostatically adsorbed to the surface. She showed how often the chemistry that occurs during the purification process has a huge impact on the type and concentration of remaining impurities, which results in distinct transport properties. The message is clear;  it is not just a means to an end! Understanding the chemistry that occurs throughout the process is crucial for material optimization and reproducibility.  Read more here Congrats Christine!

Ke is back!

ISTA hosted NaNaX10

JULY 2023

First week of July, the 10th NaNaX Conference was hosted at ISTA. The conference covered a wide variety of subjects related to colloidal nanocrystals: their synthesis, physical properties, assemblies, and applications. Maria was one of the conference organizers, along with Maksym Kovalenko, Peter Reiss, and Andrey Rogach. Mariano and Christine also were extremely helpful in the organization efforts.

Hosting NaNaX10 at ISTA was a great experience that required efforts from most of the team. Special thanks to Mariano and Christine for taking the lead and helping far and beyond.  

The conference was a success, and participants enjoyed the talks and poster presentations at the forefront of the field. Additionally, we had a wonderful dinner at the Redlingerhütte, a hike through the Vienna woods, and a wine tasting at a heuriger to end the conference. Congratulations are also in order to Christine for winning a poster presentation prize from the Royal Society of Chemistry!

We are trying to unravel the chemistry behind the formation of Ceria nanocrystals. Mariano went to Basel to work with the De Roo group, experts in oxide nanocrystals and surface chemistry. Stay tuned, exciting results will follow.


We visit our future lab


Then new lab is moving forward. Hopefully, by June next year, we will be in our new house. More fume hoods for all our wet chemistry an extra boxes for our material processing and characterization. We can’t wait!!


This summer Anna-Maria and Christoph will be with us

JULY  2020

Summer is a great time for the group as interns join the group. This year two students from TU Wien has joined us. Anna-Maria will be learning about nanocrystal synthesis. Her task, play with core-shell structures. She will work side by side with Sergi and Seungho. Christoph will explore room temperature crystallization mechanisms with Tobias. 


Seungho is back!

JULY  2020

Seungho started as an intern in the group, and last year decided to join the grad school at IST. After doing lab rotations with Freunberger and Shigemoto he decided to do the PhD with us. He will be working on nanocrystal synthesis. We are really happy to have you back in the group. We’ve missed you!


Maximilian Ritter has joined the group

JULY 2020

A new intern, Max, will spend the summer with us. He will work with Sergi trying to get large scale epitaxially connect nanocrystal superlattices. Hard task ahead!


We have now a lab technician. Welcome Clara!

JUNE  2020

After one and a half year we are really happy to have someone that will take care of our lab and equipment. Building a lab from scratch was full of surprises. One that we would never expected is that all new system will have some kind of issue! What a roller coaster of a year having to deal with so many issues. We hope that with Clara here things are more under control and we can run all our experiments smoothly.



Pending celebrations

JUNE 2020

March was a good month for the group. We submitted the first paper done fully at IST, Cheng was awarded with the Lise Meitner grant and the group got an important grant. However celebrations had to wait due to Covid-19. Finally, we could gather and cheer together for the accomplishments made.


Tobias and Alwin have joined the group

JUNE 2020

Tobias has just joinned the group as a PhD student. His first project is focused on the synthesis and characterization of nanocomposites. Looking forward to see the outcome of his interesting experiments.










Alwin is doing his master thesis with us guided by Mariano. His goal is to produce and characterize nanocrystal thin films.


The group is working remotely

MARCH 2020

In times of Covid-19, we have to stop all the lab activities and place ourselves in self-quarantine to contribute to the reduction of the virus spread. These are not easy times, but we are trying to do the best out of the situation. So we take the opportunity to catch up with literature, improve our writing skills and take some online courses in our cozy home offices.


Congratulation to Cheng!

MARCH 2020

Dr. Cheng Chang has been awarded with the postdoctoral grant Lise Meitner, which will support his research for the next two years. His project “Bottom-up Engineering of Tin Chalcogenide for Thermoelectric Applications” aims to produce low-cost Sn chalcogenide thermoelectric materials with high performance by enabling the unique potential of nanoparticles as building blocks.


Part of the group @ nanoGe


Last week Mariano and Maria travelled to Berlin to participate in the conference NanoGe. Maria gave an invited talk in the symposium Charge Carrier Dynamics and Mariano presented his first results in a beautiful poster in the symposium Fundamental Processes in Semiconductor Nanocrystals. It was an intense week, but with very interesting talks and posters. We thank the organizers for preparing such a great program!



Sergi Sànchez has joined the group


Sergi has taken the challenge to build up atomically connected quantum dot superlattices.


Cheng Chang and Guillem Montaña has joined the group


Cheng has just finished his PhD with Prof. Li-Dong Zhao, a world expert in bulk thermoelectric materials. Now he joined the group seeking for more unconventional methods to produce thermoelectric materials. He is already getting his hands “dirty” on the fume hood.










Guillem has joined the group as an intern for the next 4 month. He will be working on the synthesis of metallic nanoparticles and learn electrocatalysis. Dogukan is already sharing his wisdom with him.


Our first group retreat


We traveled to Altausseer See where we stayed for 2 days in a beautiful Lodge.  We shared home-made food, time in the nature and fruitful scientific discussions.


Nature Index ranks IST Austria #3 in the World


Yesterday “Nature Index 2018” were published. For the first time, the size of the institutions in which the publishing researchers work is also taken into account. IST shows up 3rd worldwide in the ranking!


Dr. Balazs will visit us next week to talk about colloidal quantum dot superlattices!

JUNE 2019

His talk will be entitle “Colloidal quantum dot superlattices: physical chemistry and solid-state properties

In the first part of his talk, He will discuss the considerations for the formation of colloidal quantum dot superlattices. Understanding the physicochemical phenomena that take place during assembly is of importance for developing highly ordered materials over macroscopic length scales. Using grazing incidence small angle X-ray scattering (GISAXS), the fluid and particle dynamics which lead to the final structures can be tracked, bringing us one step closer to the ideal ordered, homogeneous arrays.

In the second part of the talk, He will give an overview how the macroscopic optical and electronic properties of colloidal quantum dot assemblies can be fine-tuned by exploiting the presence of quantum confinement and the large surface-to-volume ratio, all by simple, chemical methods. The overall effect is always a combination of doping, electronic coupling or electronic structure engineering, which can be studied and distinguished using a combination of techniques, contributing to the understanding of chemistry at the nanoscale.


A warm welcome to Yu Zhang and Wei Tan
