As part of the CIMTEC conference in Montecatini Terme in Italy, Prof Barg was invited to give a lecture titled ‘3D Printed Functional MXene based Ceramics’. In the session ‘0D, 1D and 2D nanomaterials and nanostructures and soft-condensed matter’, which was part of the track 'Computational Tools in Materials Synthesis and Processing Science', she reported on current reserach of the group Complex Structured Materials within the KI-Produktionsnetzwerk.
?
In addition to many interesting discussions, the conference also provided a good opportunity to get to know other researchers in the field of 2D materials, additive manufacturing and data-driven optimization. These included one of the scientists to first discover the MXenes, which the group is currently researching.
At this year's Lange Nacht der Wissenschaft in Augsburg, a science slam was once again the prelude to a colourful programme of talks and information stands. With her slam ‘MXimal Funktional - Herrscher über das Dimensionale Chaos’, Michéle Scholl not only made the audience laugh, but also explained how MXenes are produced and why their properties are so interesting.
?
As is usual with science slams, the best slam was determined by the volume of the audience. The MXene slam won over the audience across the board and earned Michéle Scholl first place!

As in the previous year, we once again welcomed many schoolgirls in 2024 for the Girls'Day at MRM and also in our group. We prepared some experiments to give the girls an insight into the world of materials science and to get them interested in our research.
The girls were guided through our institute in small groups and were able to carry out interactive experiments at various stations. At our station, the girls were able to dip a flower in liquid nitrogen and then smash it on a table. The girls were enthusiastic about this experiment and were amazed at the fragile structure of the frozen flower.
?
We also showed the girls an experiment with a water-starch solution in which we explained the material behaviour of non-Newtonian liquids. The unexpected behaviour of this mixture is perfect for a small experiment that can even be replicated at home.
?
To make the day even more exciting, we organised a flying competition with 3D-printed soap bubble planes. The girls loved the idea and had a lot of fun testing their own aeroplanes. The group winner received another 3D-printed aeroplane, which also worked without soap bubbles, and the overall winner of the day received a printed trophy, which was awarded at the joint lunch.
All in all, Girls' Day was a complete success. We had many interested and enthusiastic girls at our institute and were pleased to give them an insight into materials science. We hope that we can contribute to this by organising events like this, to get more girls interested in the natural sciences and encourage them to study or work in this field.

As part of a research fellowship from the Alexander von Humboldt Foundation, Dr Alexander Khort is currently visiting the 伟德国际_伟德国际1946$娱乐app游戏's Faculty of Mathematics, Natural Sciences and Technology for two years. There, the chemical engineer is conducting research at the Professorship of Complex Structured Materials at the Institute of Materials Resource Management (MRM) headed by Prof Dr.-Ing. Suelen Barg.
?
Dr Alexander Khort comes from the Royal Institute of Technology (KTH) in Stockholm. His research focuses on developing new methods for producing smart nanomaterials, investigating their properties, and possible applications, and studying degradation behaviour. At KTH, the post-doc is a long-standing member of a team working on surface and corrosion science. He has already contributed to numerous publications.
?
"We hope that the collaboration with Professor Barg will provide us with expert input for our work with MXenes," says Alexander Khort. MXenes are a new type of functional 2D materials. The aim of the experiments in Augsburg is to modify and combine the two-dimensional MXenes into more complex structures. “We then aim to study functional properties of these composites and also find out how they interact with the environment," the materials researcher continues. Among other things, the expected results could provide information on the assembly and functionality of MXene-based composites for potential applications in such areas as catalysis, semiconductor sensors, and additive manufacturing. Furthermore, the researchers aim to investigate the effects that such complex nanostructures have on the environment. This could be important for the design of future EU directives on the handling of nanomaterials.
?
Dr Khort's research stay at the 伟德国际_伟德国际1946$娱乐app游戏 of Augsburg is funded by the Humboldt Research Fellowship for Experienced Researchers.
At the conference of all materials science and materials engineering student councils (KaWuM), various student councils with a background in materials science or materials engineering from all over Germany gather each semester to discuss technical and university policy issues. In addition to excursions and technical lectures, a MatWerk Slam is also part of the program of the federal student council meeting.
?
With more than 150 spectators, this Slam was the largest one in KaWuM's history. Five slammers had the opportunity to present their research in an entertaining and creative way. The different topics ranged from microstructure analysis, to nanomaterials, to the zero-point entropy of glasses. It was a great opportunity to experience the research up close and listen to the slammers as they conveyed complex topics in a simple and engaging manner.
?
The science slam by Michéle Scholl titled "MXimal funktional - Herrscher über das dimensionale Chaos" was about the synthesis of MXenes and their use in three-dimensional structures. With her lecture, she reached the third place and was awarded a small 3D-printed trophy that represents the KaWuM mascot.

On April 27th, we held the Girls' Day at our institute, which was attended by a total of 20 girls. We had prepared to give the girls an insight into the world of materials science and to inspire them with our research.
?
The girls were led through our institute in small groups and could perform interactive experiments at different stations. At our station, the girls could dip a flower into liquid nitrogen and then smash it on a table. The girls were thrilled with this experiment and were amazed by the fragile structure of the frozen flower.
?
In addition, we showed the girls an experiment with a water-starch solution in which we explained the material behavior of non-Newtonian fluids. The unexpected behavior of this mixture is perfect for a small toy that the girls could take home with them, bottled in a balloon.
?
To make the day even more exciting, we held a flying competition with 3D-printed soap bubble gliders. The girls were thrilled with this idea and had a lot of fun testing their own planes. The group winner received another 3D-printed plane that worked without soap bubbles, and the overall winner of the day received a printed trophy that was awarded during the shared lunch.
?
Overall, the Girls' Day was a complete success. We had many interested and enthusiastic girls at our institute and were pleased to give them an insight into materials science. We hope that through such events, we can help inspire more girls to become interested in the natural sciences and encourage them to study or work in this field.

We had a fantastic afternoon for children during the Easter holidays! Five children between the ages of 6 and 12 had the opportunity to conduct small experiments in our laboratory and have a lot of fun for an afternoon.
?
We started the afternoon with a demonstration of the use of liquid nitrogen. The children were thrilled to see how the nitrogen cooled the air around it and created fog. We explained to them how to work with liquid nitrogen and what precautions to take.
?
Afterwards, we together created a chemical garden that amazed the children. We explained to the children the chemical reactions that occur during this experiment and the materials needed.
?
Next, we showed the children how to perform flame coloring. The children were fascinated as we held different salts in the flame and it lit up in different colors. We explained to the children how the colors come about and which salts can be used.
?
As a grand finale of the afternoon, we had a special highlight: nitrogen ice cream! The children were amazed as we prepared the ice cream together. But not only was the ice cream visually stunning, the taste also delighted all participants.
?
Overall, the children's afternoon was a great success. The children had a lot of fun experimenting and learning. We hope that in the future we can organize more such events to inspire young people for science and research.
