Surface induced selective delamination of amphiphilic ABA block copolymer thin films

This is the result of an ongoing collaboration with Dr. N. Sommerdijk’s Biomaterials group at the University of Eindhoven (the Netherlands) and illustrates the close collaboration that exists in pursuing the design and application of novel polymeric materials between the two groups. This details work on a physical phenomenon (selective delamination) and key materials (amphiphilic block copolymers) that have subsequently been applied in the design of novel biomaterials. These results have appeared in a larger body of work including Advanced Materials, Angewandtie Chemie International Edition and the Journal of Materials Chemistry

Vibrational and dielectric properties of monolayer transition metal dichalcogenides

First-principles studies of two-dimensional transition metal dichalcogenides have contributed considerably to the understanding of their dielectric, optical, elastic, and vibrational properties. The majority of works to date focus on a single material or physical property. Here we use a single first-principles methodology on the whole family of systems, to investigate in depth the relationships between different physical properties, the underlying symmetry and the composition of these materials, and observe trends. We compare to bulk counterparts to show strong interlayer effects in triclinic compounds. Previously unobserved relationships between these monolayer compounds become apparent. These trends can then be exploited by the materials science, nanoscience, and chemistry communities to better design devices and heterostructures for specific functionalities.Comment: 4 figures, 11 page

Determination of charge transfer and recombination dynamics in perovskite solar cells

Wydział FizykiNiniejsza rozprawa doktorska jest oparta na serii siedmiu oryginalnych publikacji naukowych skupionych na dynamice transportu ładunków w perowskitowych ogniwach słonecznych, które opublikowane zostały w następujących czasopismach: Chemistry of Materials, Applied Materials and Interfaces, Chemistry-A European Journal, The Journal of Physical Chemistry C, RSC Advances, Physical Chemistry Chemical Physics i Synthetic Metals. Głównymi celami prezentowanej rozprawy było: zbadanie dynamiki transportu elektronów oraz dziur w różnych mieszankach perowskitowych; zbadanie wpływu warunków, w których są przygotowane warstwy, na działanie ogniw słonecznych; zbadanie wpływu różnych materiałów selektywnie transportujących dziury lub elektrony na transport ładunku w ogniwie (włączając te w normalnej jak i odwróconej konfiguracji) oraz korelacja parametrów makroskopowych ogniwa perowskitowego z dynamiką ultraszybkich procesów. Zaprezentowane w niniejszej rozprawie doktorskiej badania przyczyniły się do zrozumienia transportu ładunków w perowskitowych ogniwach słonecznych oraz mogą pomóc w zrozumieniu i dalszym rozwoju nieemisyjnych źródeł energii elektrycznej.The presented thesis is based on a series of seven original papers, focused on charge transport dynamics in the perovskite solar cells, published in the following journals: Chemistry of Materials, ACS Applied Materials and Interfaces, Chemistry-A European Journal, The Journal of Physical Chemistry C, RSC Advances, Physical Chemistry Chemical Physics and Synthetic Metals. The undertaken research work was aimed at characterization of the electron and hole dynamics in different composition perovskite material, determination of the effects of preparation conditions on solar cells operation, evaluation of the influence of different hole or electron transporting materials (including those in normal and inverted configuration) on the charge transfer in perovskite solar cells, and the correlation of the macroscopic parameters of the solar cells with ultrafast processes dynamics. The presented work contributed to understanding of charge transport in perovskite solar cells and might help to understand and further develop non-carbon-emissive electric current sources.The National Science Centre Poland (Narodowe Centrum Nauki) financial support under project number 2016/23/N/ST5/00070 (2017 – 2021) the Ministry of Science and Higher Education (Ministerstwo Nauki i Szkolnictwa Wyższego) under project “Diamentowy Grant” number DIA2016 001946 (2017 – 2022

Multidisciplinary research in space sciences and engineering with emphasis on theoretical chemistry

A broad program is reported of research in theoretical chemistry, particularly in molecular quantum and statistical mechanics, directed toward determination of the physical and chemical properties of materials, relation of these macroscopic properties to properties of individual molecules, and determination of the structure and properties of the individual molecules. Abstracts are presented for each research project conducted during the course of the program

Biocompatible nanostructure materials

Materials suitable for medical systems have always been the product of interdisciplinary collaboration between material and biological science. As well as different area of physics and chemistry. For medical application materials must not damage blood cells or bones and must be resistant. Some implant materials for chemical bonds can be stabilized by implantation of different elements or deposition of very thin films. In this work we presented some results for replacement of damaged human tissues.Physical chemistry 2008 : 9th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 24-28 September 200
