Skills upgrading in progress!
We have just finished a short course on Introduction to Quantitative XRD analysis organized by Dr. Youjun Deng (Texas A&M University) and Jakub. The course gathered 31 participants both from AGH and Texas A&M as well as other guests. Dr. Deng currently works at AGH University within Ulam scholarship financed by Polish NAWA agency. He has broad experience in QXRD and he shared his knowledge on fundamentals of Rietveld refinement method during 3 comprehensive lectures. The last part of the course was focused on practical use of Profex software. Now we can start to implement the gained knowledge in our research.
Recently, we received the news that Ania has been granted a CMS (Clay Minerals Society) travel grant! This grant will enable her to participate in the 17th International Clay Conference in Istanbul (Turkey). Ania’s poster presentation will cover the results of her MSc. thesis: Impregnation of smectite with layered double hydroxides of different chemistry for the simultaneous removal of Cr(III) and acid blue dye.
The experiments of our Master’s students are already at an advanced stage. Girls have spent long hours in the laboratory carrying out many experiments. The results of are so promising that their work will not just be over at the thesis stage. The girls have an intensive writing period ahead of them, and in a few months – the defenses!
Another great news in the MBA Group! Klaudia received a travel grant awarded by Association Internationale pour l’Étude des Argiles (AIPEA). The financial support allows to attend the 17th International Clay Conference in Istanbul (Turkey). Klaudia is going to present results of her MSc thesis devoted to hydrotalcite-zeolite heterocoagulated materials with dual adsorption properties.
Karolina is now halftime through her stay at Faculty of Environmental Sciences, Czech University of Life Sciences. Under the supervision of Dr. Barbora Hudcová, Karolina investigates the V(V) removal mechanisms by layered double hydroxides. This involves many adsorption experiments as well as various modelling approaches.
Await the publication, because the results are very interesting!
To get the new year off to a good start, enjoy reading the article published in Journal of Cleaner Production in January.
Karolina and Jakub in cooperation with Mateusz Marzec from AGH Academic Centre for Materials and Nanotechnology described the adsorption properties of layered double hydroxides derived from magnesite. The huge number of hours in the lab translated into very interesting results. We investigated the removal of as many as six anions in several extensive experiments.
We did some great things this year in the MBA Group!
At a year-review (hybrid) meeting, we summarized all our activities in 2021. During this year, we have published 7 papers. Several topics were covered, including adsorbents (layered double hydroxides, modified smectites, sawdust) and montmorillonite-polysiloxane composites. We have attended conferences and workshops. Two of our projects funded by NCBiR and NCN were successfully closed. We had a great time meeting with research groups from Oulu University and Texas A&M University. With the new grant proposals submitted, an ongoing project, four MSc and one PhD projects to be completed, and new papers in preparation, we hope for the best in 2022.
Keep in touch with us, we already know how to kick off the new year!
A new publication by Karolina and Jakub in cooperation with Michal Slaný from the Slovak Academy of Sciences was published in the Journal of Environmental Chemical Engineering. The publication describes a simplified method for the synthesis of layered double hydroxides. Check it out!
In March 2022 Dr. Youjun Deng will join the MBA group! He has received a scholarship from NAWA within Ulam Programme and was chosen as one of 51 foreign scientists who will visit Poland to carry our research. Dr. Deng is an associate professor of soil mineralogy at Texas A&M University (USA).
His research is focused on the occurrence of soil and clay minerals in nature and under man-made conditions and the relationships between mineral structures and their functions e.g. 1) reactions of minerals with natural and synthetic organic, inorganic, and biological compounds of environmental and industrial importance, 2) mineral transformations and 3) civil engineering challenges.
He has been awarded nearly 5 million $ of research funds, published 66 reviewed articles, 5 book chapters and 1 book. His publications were cited over 1500 times and he has an h-index of 23. He has given 162 presentations (38 invited). Dr. Deng is an active and leading member in 5 societies including the Clay Minerals Society and Soil Science Society of America.
His research at AGH is aimed to select and to modify natural clay minerals and synthetic layered double hydroxides to detoxify zearalenone, one common toxic metabolite produced by fungi in crops, food and feed. Clay minerals such as montmorillonite and synthetic LDHs have been successfully used to remove aflatoxins and fumonisins. However, such an efficient binder for zearalenone is not known.
On 13-17.09.2021, Karolina participated in the 9th International Workshop on Qualitative and Quantitative Analysis of Clays and Clay Minerals organized in Höhr-Grenzhausen (Germany) by German-Austrian-Swiss Clay Group DTTG (Deutsche Ton- und Tonmineralgruppe). The most experienced scientists shared their knowledge!
The workshop covered the topics of clays, clay minerals and mixed layer minerals. The variety of methods used for the characterization of clays creates many opportunities in projects on mineral-based materials. The gained knowledge will definitely improve our research. It was great to meet all amazing clay scientists, share experience and do the networking.
Check out our scientific paper on the removal of styrene solvent by modified smectite clay minerals. Styrene is one of the most important industrial solvents. It is used in the production of e.g. polystyrene and polyester resins. Its emission needs to be controlled and this is possible through the use of adsorbents.
Time to sum up the summertime at MBA!
We have found the time for both work and rest. Our PhD Students, Karolina and Maciej participated in conferences and workshops, and ended up with awards for the best presentations. MSc students continued their research in the labs and presented their progress during meetings. We have also found the time for integration and altogether had a trip to Bolechowicka Valley.
Now, after the holidays, it’s time to prepare for a new academic year and further research. We’re ready for action!
After many online group meetings and with holidays approaching, almost the whole group gathered in one place. We had a great trip to Bolechowicka Valley, near Cracow. With one peek summited (excellent views, no supplementary oxygen!) and a nice walk, we well-deserved the pizza. No science was talked that day, but we enjoyed the trip as much as the youngest participants.
Today we share a little sneak peek of our research. Here, Klaudia is observing her materials under Scanning Electron Microscope. Under Jakub’s supervision, she performs experiments aimed at obtaining hydrotalcite-zeolite mineral composites with dual adsorption properties. The combination of zeolites and LDH results in a composite developed for effective, simultaneous removal of anions and cations from wastewaters. Within a year ahead of their graduation, all our MSc students are doing great job!
May was full of meetings perfect for discussing the results of our research!
We had a group meeting where Agnieszka and Kinga shared the progress of research in their master’s theses. We had a long and rich in interesting results meeting with a group from A&M Texas University. At the end of the month, Jakub gave a talk on minerals in technology for the WGGiOŚ AGH University of Science and Technology, and Karolina led a panel discussion at the Job Fair for PhD students WSForum organised by KRD. At the beginning of June, Mateusz gave a talk at the conference ‘Topical Issues of Rational Use of Natural Resources’ receiving a distinction.

Howdy Aggieland! -> A&M Traditions
Another informal international meeting is behind us. This time we have met clay scientists from Department of Soil and Crop Sciences (Texas A&M University, USA).
Is it efficient to remove radionuclides by zeolites? Why some kaolinites are not reactive? How to modify smectites for use in polymer composites and for styrene removal? These were the main topics of the discussion.
Those who survived the over two-hour meeting are in the photo.
See you next time.
During our group meetings, students have a chance to get feedback from others on their research. On our last group meeting (11.05.2021) Agnieszka and Kinga shared with us the progress and newest results of their experiments for the MSc diploma under supervision of Jakub.
Agnieszka Giera -> Different approaches and efficiency of mineral adsorbents regeneration for zinc removal from aqueous solutions
Kinga Lis -> Synthesis of mineral adsorbents doped with transition metals for the removal of selected organic compounds from aqueous solutions
Agnieszka and Kinga, we keep our fingers crossed!
We have also welcomed our new members, Maciej and Eugeniusz!
We have just launched a new channel! Researchers, students, industrial representatives and our friends can now follow us on LinkedIn. We will be sharing our research and innovations and you will get the chance to know us better. Spread the news and let’s network together.
Most exiting conferences have been canceled or postponed in 2021. So what? We decided to arrange our own mini-conferences. The first one gathered 19 participants from MBA group and our colleagues from Oulu University (Finland). We shared great ideas and insightful thoughts about the common areas of research.
Looking forward to meet Texas A&M group next month.
