Scientific event “Third Workshop on Size-Dependent Effect in Materials for Environmental Protection and Energy Application” SizeMat3.
The 3rd International Workshop on Size-Dependent Effect in Materials for Environmental Protection and Clean Energy Application (SizeMat3) was held from 12 to 15 September 2021 in Pomorie (Grand Hotel Pomorie) Bulgaria. The scientific forum was organized by the Institute of General and Inorganic Chemistry at Bulgarian Academy of Sciences, which is one of the leading scientific organizations in Bulgaria in the area of materials for environmental impact. SizeMat3 was carried out within the project “European Twinning on Materials Chemistry Enabling Clean Technologies” (TwinTeam) of the National Science Programme “European research network”, (coordinated by IGIC-BAS). Dimensional effects in materials for environmental protection and clean energy production were discussed as an innovative approach for the development of perspective materials with improved properties. The reported scientific results were focused on three main areas of materials science:
Topic A: Materials and thin films for environmental protection;
Topic C: Materials for clean energy storage;
Topic C: Ceramics/Bioceramics and Glasses for Better Living (with applications in optics, molecular electronics and medicine).
More than 80 Bulgarian and foreign scientists participated in the SizeMat3 forum. Eight plenary lectures were given and seven of them were presented by leading researcher from the three TwinTeam partner organizations: Imperial College London – Department of Materials (UK), Karlsruhe Institute of Technology, Institute for Applied Materials – Energy Storage Systems (Germany) and University of Seville, Materials Science Institute of Seville (Spain). Scientists from Russia and Slovakia, as well as many young researchers, PhD students and students from IGIC-BAS, FChPh-SU, Institutes of BAS and University of Mining and Geology were attended in the forum. SizeMat3 is the third in a series of international seminars in Bulgaria, organized by the IGIC-BAS, which attracted once again the interest of the scientific community to the selected topics. The scientific forum was organized in eight lecture sessions and two poster sessions. The total number of oral presentations (excluding plenary) was 10, flash presentations – 4 and poster presentations on topic A – 35, on topic B – 14 and on topic C – 12.
Five young scientists were awarded certificates for the best poster in all three areas and Theoretical Chemistry, as well as for the best virtual poster. All presentations’ abstracts were summarized in a Book of Abstracts, which, together with the workshop program, are available on the website: http://twinteam.igic.bas.bg/sizemat/, specially prepared for the scientific event.
About 20 papers, including conference proceedings will be published in a special issue of Materials Today: Proceedings. Reviewer’s process will be managed by three guest editors from IGIC. The deadline for submitting papers 10 December 2021.
It is planned to hold an international scientific conference SizeMat3 within the TwinTeam project.
The scientific event will be organized by the Institute of General and Inorganic Chemistry – BAS and will be held at the Grand Hotel Pomorie in the period 12-15 September 2021.

Karlsruhe Institute of Technology (KIT) – Institute for Applied Materials – Energy Storage Systems
- In March-April 2022, Assoc. Prof. Dr. Petar Tsvetkov, Assoc. Prof. Dr. Delyana Manasieva and Assist. Prof. Dr. Mariya Kalapsazova was on a short specialization at the Karlsruhe Institute of Technology in Germany. There they got acquainted with the work, available equipment, and techniques of colleagues from the institute IAM–ESS (Institute for Applied Materials – Energy Storage Systems). A technique for in-situ XRD and in-situ Raman measurement of an electrochemical cell in a cycling process was demonstrated. A number of in/ex-situ XRD (in transmission geometry using different X-ray (Ag, Cu)) and in-situ Raman measurements of electrochemical cells with cathode materials were performed, as well as galvanostatic measurements of electrochemical cells. Colleagues from IGIC also got acquainted with sample preparation, assembly, and measurements of specific XAS electrochemical cells and conducting in-situ XAS on a synchrotron ANKA.
- Assoc. Prof. Dr. Petar Tsvetkov held a meeting with Dr.-Ing. André Weber, head of the laboratory for testing solid fuel cells at the Institute for Applied Materials – Electrochemical Technologies (IAM-ET), where discussed possibilities for future impedance research of a new type of solid electrolyte.
