The group is working remotely
MARCH, 12- 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!
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
NOVEMBER 4-8, 2019
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
NOVEMBER 4, 2019
Sergi has taken the challenge to build up atomically connected quantum dot superlattices.
Cheng Chang and Guillem Montaña has joined the group
OCTOBER 1, 2019
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
SEPTEMBER 18-20, 2019
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 19, 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
JUNE 17, 2019
Yu Zhang from IREC in Barcelona and Wei Tan from Imperial College London are going to spend the summer in our lab working on solution processed thermoelectric materials. They are already hand on!
We got the JACS cover!
MAY 24, 2019
Our cover art representing our paper Ligand-Mediated Band Engineering in Bottom-Up Assembled SnTe Nanocomposites for Thermoelectric Energy Conversion has been selected for the front cover in the Journal of the American Chemical Society. We thank Roger Hasler for all his effort and creativity in this endeavor.
Dr. De Roo is visiting IST to explain us about surface chemistry!
APRIL 12, 2019
He will explain us about his studies on organic ligands through solution and solid state NMR spectroscopy. To illustrate the usefulness of the NMR toolbox, he will work through several case studies on a variety of nanocrystal types such as metal oxides or CsPbBr3 perovskite nanocrystals. You can read more about his work in the following publications. Chem Mater 2018, 30, 5485-5492; ACS Nano 2016, 10, 2071-2081; Angew. Chem.-Int. Edit. 2015, 54, 6488-6491; Nat. Mater. 2016, 15, 517-521; Chem Mater 2017, 29, 6104-6113; Chem. Mat. 2018, 30, 8034-8039.
We have done our first synthesis!
JANUARY 30, 2019
It took us almost 5 months but finally we have the fume hoods fully equipped and our small glovebox running.
IST Austria ranked #8 Nature Index 30 under 30 List
IST was listed as number 8 in the Nature Index as a young institute that surpasses its peers in high quality science. The complete list consists of universities and research centers that are under 30 years old.
Prof. Dr. Paul Alivisatos will be awarded 2018 Wilhelm Exner Medal in Vienna!
OCTOBER 1, 2018
The award ceremony along with the Exner Lectures will take place at Eschenbach Palace in Vienna on October 23rd and 24th. In the ceremony, together with Thomas Jennewein, Gregor Weihs and Zhenan Bao, Paul Alivisatos will receive the Wilhelm Exner Medal for his contributions to Nanomaterials development. He will be also giving a lecture entitled “Quantum Dot Light Emitters: From Displays to Enabling a New Generation of Energy Conversion Systems” on October 24. Prof. Jürgen Fleig (University of Technology, Vienna) and Maria Ibáñez will give lectures honoring the Wilhelm Exner Medalist with the title “Energy conversion and energy storage by moving ions in solids” and “Rational Design of Thermoelectric Materials from Nanocrystal Building Blocks” respectively. Find out more and register for the event!
Building a Campus for Science!
IST Austria is expanding to include the fifth laboratory building for chemistry, grad school and library.
Save the date (October 11) for the ceremony where the official start of the construction will take place. Do not forget to register if you would like to attend the event to learn more about the new developments at IST Austria. Maria Ibáñez will be introducing the new research field at IST Austria during her talk at the ceremony.
