<p><strong>V čistých laboratořích výzkumné infrastruktury CEITEC Nano na CEITEC Vysokého učení technického v Brně se nachází zhruba čtyři metry vysoký transmisní elektronový mikroskop TITAN pro výzkum materiálů na atomární úrovni. A právě toto vědecké zařízení se loni dočkalo dvou významných upgradů o dvě nejmodernější technologie – korektoru aberací elektromagnetických čoček pro skenovací transmisní elektronovou mikroskopii a spektrometru energiových ztrát elektronů vybaveného kamerami s dnes nejcitlivějšími senzory. Díky těmto upgradům se z TITANU stalo špičkové zařízení, které lze v dané konfiguraci najít jen v několika nejmodernějších laboratořích na světě.</strong></p><p><strong>Mikroskop TITAN Themis</strong> byl vyroben v roce 2015 firmou FEI (dnes Thermo Fisher Scientific) a na CEITEC VUT slouží od roku 2016. Už při svém pořízení patřil k <strong>nejvýkonnějším komerčně dostupným elektronovým mikroskopům</strong>, chyběl mu však korektor optických vad čoček formujících úzký elektronový svazek skenující vzorek. To znamenalo omezené rozlišení i nižší schopnost analyzovat chemické složení a fyzikální vlastnosti materiálů na atomární úrovni.</p><p><i>„Korektor aberací poslední generace typu S-CORR umožňuje zaostřit elektronový svazek na velikost až dvakrát menší než atom a zároveň s vyšším elektronovým proudem. Tím došlo k zásadnímu zvýšení rozlišení i analytických schopností mikroskopu,“ </i>vysvětluje <strong>Jan Michalička</strong>, garant mikroskopu TITAN. <i>„Náš mikroskop tak díky novému korektoru dosahuje světově nejvyššího standardu v rozlišení, konkrétně méně než 50 pikometrů při urychlovacím napětí 300 keV.“ Pro lepší představu dodává přirovnání: „Lze si představit poměr velikosti golfového míčku a naší Země. A právě takový poměr má atom o velikosti 100 pm vůči golfovému míčku.“</i> Díky tomuto rozlišení jsou vědci schopni nejen zobrazit jednotlivé atomy, ale další analýzou také určit jejich chemickou podstatu. To má zásadní význam například pro vývoj nových katalyzátorů pro ekologičtější chemický průmysl.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Upgrade_transmisniho_elektronoveho_mikroskopu_TITAN_zaradil_CEITEC_mezi_elitni_laboratore_8ebd8d7245.jpg" alt="CEITEC/CEITEC BUT archive: Upgrade transmisního elektronového mikroskopu TITAN zařadil CEITEC mezi elitní laboratoře: Rozdíly v rozlišení před a po instalaci korektoru." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Upgrade_transmisniho_elektronoveho_mikroskopu_TITAN_zaradil_CEITEC_mezi_elitni_laboratore_8ebd8d7245.jpg 245w," sizes="100vw" width="1600" height="904"></p><p>Nový korektor zároveň umožňuje mikroskopu vysoké rozlišení i s elektrony o nízké energii. To je klíčové pro studium velmi citlivých materiálů, jako je grafen a další dvourozměrné struktury, které by silnější elektronový svazek poškodil. <i>„Elektrony se vzorkem silně interagují a na atomární úrovni jej mohou poškodit, například mu změnit strukturu a chemické složení. S novým korektorem dokážeme dosáhnout atomárního rozlišení i při nejnižším urychlovacím napětí 60 keV a díky tomu studovat i velmi citlivé materiály prakticky v nezměněném stavu,“</i> říká Jan Michalička.</p><h4><strong>Dodatečná instalace korektoru v laboratoři CEITEC je světově unikátní</strong></h4><p><strong>Korektory optických vad elektromagnetických čoček je výjimečná technologie</strong>, která zcela změnila svět elektronové mikroskopie. Dlouhou dobu byly považovány za technicky nemožné a absence korektorů v podstatě bránila výzkumu struktury a vlastností materiálů na atomární úrovni. Teprve v 90. letech se čtveřici vědců – Haraldu Roseovi, Maxu Haiderovi, Knutu Urbanovi a Ondřeji Křivánkovi – podařilo tuto technologii realizovat a za svůj přínos získali v roce 2020 prestižní Kavliho cenu. <i>„Korektory se v základu skládají z dvojice komplexních čoček, přičemž každá z nich obsahuje řadu magnetických multipólů. V případě korektorů vynalezených prvními třemi jmenovanými se vady odstraňují dvěma hexapólovými čočkami. Takový koncept má i náš nový korektor“ </i>doplňuje Jan Michalička.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Upgrade_transmisniho_elektronoveho_mikroskopu_TITAN_zaradil_CEITEC_mezi_elitni_laboratore_2_c7e74d8554.jpeg" alt="CEITEC/CEITEC BUT archive: Upgrade transmisního elektronového mikroskopu TITAN zařadil CEITEC mezi elitní laboratoře: Dodaný korektor před instalací, v pozadí mikroskop TITAN." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Upgrade_transmisniho_elektronoveho_mikroskopu_TITAN_zaradil_CEITEC_mezi_elitni_laboratore_2_c7e74d8554.jpeg 117w," sizes="100vw" width="1600" height="2133"></p><p>Dodatečná instalace korektoru je sama o sobě v dnešní době <strong>unikátní</strong>. Podobně složité technologie se zpravidla montují už při výrobě mikroskopů v továrně, v tomto případě v Holandsku. V Brně se však podařilo úspěšně upgradovat mikroskop o korektor v omezených podmínkách laboratoře. Instalace korektoru trvala zhruba čtyři měsíce a neobešla se bez demontáže velké části mikroskopu. „<i>Touto instalací jsme se v podstatě vrátili do doby, kdy zmíněná čtveřice vědců umístila na starší mikroskop svůj prototyp korektoru, a zdokonalila tak jeho výkon,“</i> říká s úsměvem Jan Michalička s tím, že nejsložitější bylo precizní seřízení korektoru a celé optiky mikroskopu, aby bylo dosaženo špičkových parametrů. <i>„I když už většinu věcí řídí počítače, na světě existuje jen málo lidí, kteří dokážou instalovat a vyladit korektor do úrovně nejvyšší přesnosti.

Upgrade transmisního elektronového mikroskopu TITAN zařadil CEITEC mezi elitní laboratoře

<p><strong>Vědci z Ústavu organické chemie a biochemie AV ČR pronikají do detailů genové transkripce. Popsali dosud neznámý molekulární mechanismus, kterým může začínat přepis genetické informace z deoxyribonukleové kyseliny (DNA) do ribonukleové kyseliny (RNA). Zaměřili se na zvláštní molekuly nazývané alarmony, které se vyskytují v buňkách napříč organismy a jejichž hladina se často zvyšuje při buněčném stresu.

U eukaryotních organismů, kam patří i lidské buňky, je nejznámější čepička, která se podílí na stabilitě RNA a regulaci jejího dalšího osudu. V posledních letech se však ukazuje, že existují i alternativní, nekanonické RNA čepičky, jejichž vznik a mechanismus připojení k RNA se zatím vymyká lidským znalostem. Mezi ně patří například tzv. alarmonové čepičky, tvořené molekulami dinukleosidpolyfosfátu, alarmonů, které chrání buněčnou RNA ve chvílích, kdy je buňka v ohrožení.</p><p>Tým <a target="_blank" rel="noopener noreferrer" href="https://cahova.group.uochb.cz/cs"><strong>Dr. Hany Cahové</strong></a> se ve své studii zaměřil na RNA polymerázu z bakterií a sledoval, jakým způsobem může tento enzym zahájit transkripci za využití dinukleosidpolyfosfátů (NpNs) místo běžných stavebních bloků RNA. Vědci vůbec poprvé popsali na atomární úrovni, jak může vznikat RNA s alarmonovou čepičkou přímo při zahájení přepisu genu.

Jejich studie pomáhá odhalovat procesy, které provázejí přepis genetické informace z DNA do RNA.</p><p>Hana Cahová k tomu dodává: <i>„Popisujeme něco, co se v buňkách skutečně děje a co nyní dokážeme pozorovat přímo na úrovni jednotlivých molekul. Získáváme tak odpovědi na zásadní otázky týkající se buněčných procesů, například jak se buňky přizpůsobují stresu.

Pravděpodobný mechanismus tohoto specifického typu zakončení RNA spočívá v přímém začlenění dinukleosidových polyfosfátů RNA polymerázou jako nekanonických iniciačních nukleotidů. Dosud však nebylo známo, jakým způsobem se tyto sloučeniny vážou do aktivního místa RNA polymerázy během zahájení transkripce. V této práci jsme in vitro studovali iniciaci transkripce za použití série DNA templátů v kombinaci s dinukleosidovými polyfosfáty a modelovou RNA polymerázou z bakterie <i>Thermus thermophilus</i>. Zjistili jsme, že místo zahájení transkripce se může lišit v závislosti na kompatibilitě konkrétního templátu a použitého dinukleosidového polyfosfátu. Struktury iniciačních transkripčních komplexů s dinukleosidovými polyfosfáty získané pomocí kryogenní elektronové mikroskopie odhalily, že obě nukleové báze v molekule mohou párovat s DNA templátem. První kódovaný nukleotid se páruje kanonickým Watsonovým–Crickovým způsobem, zatímco druhá nukleová báze se váže nekanonicky prostřednictvím reverzního Watsonova–Crickova párování. Tato práce tak poskytuje strukturní vysvětlení mechanismu, kterým dinukleosidové polyfosfáty zahajují transkripci RNA.</p></div></div>

<h5><strong>09:00 Welcome Introduction &amp; Video of Geoff Winkett , Agilent Technologies</strong></h5>
<h5><strong>9:10 The World of Microplastics Up to Date an Overview</strong></h5>
<ul>

<h5><strong>09:50 Release of Plastic Additives and Microplastic Particles from Different Consumer Products into Water under Accelerated UV Weathering Conditions</strong></h5>
<ul>
<li>Lars Hildebrandt (Scientist, Helmholtz Zentrum Hereon)</li>
</ul>
<p>Photodegradation of plastic products is known to accelerate weathering and the resulting release of chemical additives and particles to the environment, however these processes are complex. Here, eight different plastic consumer products were leached in double distilled water under exposure to strong ultraviolet (UV) light for ten days, and the chemical composition of the leachates was compared to their respective dark controls. The leachates and plastic particles were investigated with a wide battery of chemical analytical tools to broadly characterize the underlying processes and possible hazards. These covered (a) metal(loid) analysis, (b) microplastic analysis, (c) analysis of &gt;70 organic target analytes and (d) nontargeted screening of the extracts.</p>
<h5><strong>10:10 Identification of Polymers Using Machine Learning</strong></h5>
<ul>
<li>Xin Tian (Scientific Researcher, KWR NL)</li>
</ul>
<p>Microplastics and other polymers are found in the environment. For this reason, it is important to have reliable methods to identify them. Methods used to detect nano- and microplastics in the environment include Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, laser-directed infrared (LDIR) spectroscopy and thermogravimetric analysis (TGA)/pyrolysis. These measurement techniques can provide a lot of information, but sometimes require a database with a lot of high-quality data to compare measurement results. Machine learning (especially classification models) can help improve data processing and accuracy.</p>
<p>Recent research has looked at how machine learning can help improve the accuracy of identification with infrared spectroscopy. Different computer models were tested and examined to see if the accuracy increases and if it does not require an unreasonable amount of computing power and time. This research focused on finding an effective method for identifying polymers in the environment based on their mid-infrared spectroscopic signals.</p>
<p>Polymers are identified by infrared spectroscopy by comparing their spectra with spectra in a database/library. This works well for new polymers, which are clean and barely degraded. Since polymers from the environment are actually degraded, comparing their infrared spectra with spectra in the library is difficult. This is because the spectra in the library often have large deviations from the spectra of the measured polymers. Increasing the number of spectra in the library is not possible because the number of spectra of environmentally degraded polymers is almost infinite. The study therefore looked at whether the problem of small data sets can be addressed using machine learning. The research presents a data enrichment technique to generate spectra of degraded polymers from single spectra of a limited number of samples. Four models were tested using these spectra to identify polymers. The study shows that all the models achieve high success rates, thereby facilitating the identification of polymers from environmental samples. Moreover, the research shows that it is not necessarily the most advanced computer model (particularly deep neural network models) that yields the best results.</p>
<h5><strong>10:30 From the River to the Sea: Microplastics in Sediments of the Thames River</strong></h5>
<ul>
<li>Friederike Strock (Postdoc, German Federal Institute of Hydrology)</li>
</ul>
<p>Microplastics have been investigated for over 45 years especially in the marine environment, but only in the past years research has started to focus on freshwater environments. In the frame of the H2020 LABPLAS project, sediments along the course of the Thames river in its freshwater and estuarune part were studied in order to better understand the sources, transport, distribution and impacts of plastic pollution and to detect the amount of plastics transport via the rivers into the sea.</p>
<p>In the frame of the project, a winter and a summer campaign were conducted 2022 and samples taken from 6 sites within the study area. Sediment samples were taken with a Van Veen grabber from the edge of the river, wet sieved into different compartments (10 100 µm, 100 1000 µm, &gt;1000 µm), density separated and the organic matter digested. The plastics from the sediments were characterized with a Laser Direct Infrared (LDIR). The preliminary results reveal that microplastics are present in all samples. The amount of particles varies significantly between the sampling sites showing the importance of industrial emissions and cities.</p>
<h5><strong>10:50 Good Laboratory Practices to Characterize Microplastics Using Quantum-Cascade Laser Reflectance Absorbance Spectrometry</strong></h5>
<ul>
<li>Jose Manuel Andrade Garda (Professor Analytical Chemistry, University of A Corunna)</li>
</ul>
<p>The nowadays broad societal interest in microplastic pollution demands urgent responses and actions. For these be possible politicians must set rules which, in turn, are not possible at all without sound scientific data. Unfortunately, there is a general feeling that the experimental results obtained so far are not still fully comparable and, further, that the monitoring field where hundreds or samples are taken is not being fully considered. Scientific studies and future regulations depend critically on a reliable identification of the polymers (if any) that constitute the suspicious particles under study. Out of the various analytical techniques to characterize them a novel one based on reflectance-absorbance spectrometry, commercialized as LDIR, outstands. It uses a tuneablemid-IR quantum cascade laser (QCL) to imaging a reflective microscopy slide or a metal-coated filter in a remarkable small timeframe. This communication is meant to present best practice guides to overcome some obstacles/difficulties in routine measurements, and open a path for field monitoring; among them: the adequacy of the spectral range, the variation of the peak&#39;s intensities with the size of the particles; the speed of the analysis as a function of the instrumental setup; the criterion to identify unknown spectra (a tiered approach is finally suggested); and how to differentiate fibers and fragments semiautomatically. Also, an empirical dependence of the depth of penetration of the QCL laser in common plastic particles is approached first time.</p>
<h5><strong>11:10 Chemical Characterization of Microplastics using Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GC-MS)</strong></h5>
<ul>
<li>Soledad Muniategui-Lorenzo (Pull Professor of Analytical Chemistry, University of A Corunna)</li>
</ul>
<p>The implementation of monitoring programs for Microplastics requires reliable and standardisedmethods. Fourier Transform Infrared (FTIR) and Raman spectroscopy techniques are the most commonly used for Microplastics analysis. However, thermal analytical techniques are currently gaining popularity. This presentation focuses on the potential of mass-based thermal analytical techniques, in particular, Pyrolysis coupled with Gas Chromatography-Mass Spectrometry (Py-GC-MS), for the accurate qualitative and quantitative analysis of microplastics in environmental matrices. It outlines some advantages and good laboratory practices of this approach, the importance of method normalisation, and how it can provide detailed information on polymers and plastic additives.</p>
<h5><strong>11:20 Analysis of Fibrous Microplastics Using Laser Direct Infrared Imaging</strong></h5>
<ul>
<li>Monique Greiner (Research Associate, Hohenstein Laboratories)</li>
</ul>
<p>In the research field of microplastics the identification of their source is important in order to develop strategies to minimize the pollution. A major percentage of microplastics originates from textiles. One pathway into the environment are washing procedures because the textiles release fibers during the process. Therefore our aim was to find a fast and easy way to identify fibers. In our presentation we want to give insights in our approach to the analysis of fibrous microplastics with the LDIR 8700. We will talk about our strategies, the results we achieved and difficulties we faced.</p>
<h5><strong>11:40 Looking beyond the Polymer: Using Thermal Desorption GC MS to expand our understanding of Microplastics</strong></h5>
<ul>
<li>Jan Peter Mayser (Market Specialist, Markes International)</li>
</ul>
<p>Detecting and analysingmicroplastics in the environment is challenging. The method must be able to detect and distinguish between a large variety of polymers. Additives, such as hardeners, flame retardants and preservatives, used during the manufacturing process and other compounds, that can adhere to the surfaces of microplastics from their environment, can affect their toxicity assessment. These additives could be used to link the microplastics found in the environment to their original use or potentially even back to the manufacturer.</p>
<p>In this study, various salts were sampled and filtered and analyzed for their microplastic content. TD–GC–MS was used to identify and measure which concentration of the plastic PS, PET, PVC and Nylon 6 had been incorporated into the crystalline structure of the salt during evaporation. By using direct desorption and backflushing technology, a large sample size could be easily isolated from the lab environment during analysis while ensuring a large range of volatile organic compounds (VOCs) including the marker compounds for four polymers could be trapped and analyzed.</p>
<p>The VOC-profile of the microplastics not only gave information about the polymer and its concentration within the sample, but further information about the toxicity could be extracted. This enabled the determination and tentative identification of additional compounds in the samples, such as dimethyl ether, acrolein and cyclopentane. These are used in the process of manufacturing plastics, so could assist with identifying the source of the plastics. For the four analysed polymers distinct marker compounds could be identified and calibration curves determined for each polymer. In all of the real-world salt samples microplastics were identified, highlighting the ubiquitous nature of the microplastic contamination.</p>
<p>This further information about the origin of the polymer, as well as the origin of the microplastic particles can be gathered by investigating the full VOC-profile obtained by TD-GC-MS. This allows both additional polymer information and particle source characterization.</p>
<h5><strong>12:00 Tiny Problems</strong></h5>
<ul>
<li>Roxana Sühring (Assistant Professor in Analytical Environmental Chemistry, Toronto Metropolitan University)</li>
</ul>
<p>Microplastics have been on the front page of newspapers, a dominant topic for environmental research (and funding), and a recent focus for regulatory action across the globe. Their potential impacts have been classed as a planetary boundary threat and new studies are published daily, reporting microplastics virtually anywhere on the planet. But despite numerous publications, there are still a lot of open questions on how to effectively and reproducibly characterize microplastics. How can microplastic characterization be automized? What is the impact of additives or weathering on the characterization accuracy?</p>
<p>In this presentation I will provide an overview and the first results of a research collaboration between Agilent technologies and the Emerging contaminants lab at Toronto Metropolitan University that works on addressing some of these questions. Our research aims to create a versatile microplastic library using weathered and new plastics commonly found in the environment. This library will additionally be used as a training set for developing automated particle characterization for the LDIR.</p>
<h5><strong>12:20 Identification of Microplastic Particles in Soil Using LDIR</strong></h5>
<ul>
<li>Martine Graf, PhD (Student &amp; Senior Technician, Bangor University)</li>
</ul>
<p>The use of agricultural plastic has become increasingly concerning in an environmental setting in recent years; in Europe alone, an estimated 2.5 million tones of plastic mulch films are used each year. The use of mulch films for crop production has been promoted by governments worldwide due to its many benefits, however the removal of these films from the soil can be difficult due to their poor mechanical strength and fragmentation, and barriers such as poor incentives for farmers and underdeveloped infrastructure for collection and disposal. The latter often leading to the films being discarded or incinerated along field margins, or ploughed back into the fields, leading to an accumulation of plastic legacy in soil. To evaluate the microplastic pollution levels in agricultural soils, we are i ) conducting a global soil survey in all partner countries; ii) assessing the degradation and fragmentation of conventional and biodegradable plastic mulch films in soil, and measuring the resulting microplastic production rate; and iii) measure the degradation and movement of microplastic in soil after repeated application. Microplastics are extracted from soil using targeted methods for different polymer types, and analysed using fluorescent microscopy, FTIR spectroscopy, and LDIR spectroscopy.</p>

<p><strong>Electron paramagnetic resonance (EPR) spectroscopy is an innovative tool to detect free radicals in skin and blood plasma. It is a powerful technique that can help us learn more about the redox status, and induced oxidative stress by quantification and characterization of different types of radicals formed in the skin, skin models, skin cells, and blood plasma.</strong></p><p>In skin, a critical radical concentration characterized by the reversal of primary ROS (reactive oxygen species) to secondary LOS (lipid oxygen species), leading to increased lipid peroxidation and consequent cellular damage is known. This reversal indicates a change in the redox balance. EPR spectroscopy represents an innovative sensitive tool to assess the antioxidant status by stress response methods in skin and blood plasma. The redox status and oxidative stress investigations were performed in blood plasma samples, and in ex vivo and in vivo skin. These permit evaluating antioxidative supplements and formulations but also studying the influence of oxidative stress, which could be induced by irradiation, lifestyle, or pollution. Cigarette smoke is a good representative of pollution and it is known that it affects the whole body and can induce skin aging. These effects could be shown using EPR spectroscopy but also other methods such as cytokine analysis, resonant Raman spectroscopy, and biochemical assays. New insights about direct smoking and passive smoking will be presented.</p><p><strong>Key Learning Topics:</strong></p><ul><li>EPR as a tool to measure reactive oxygen and lipid oxygen species in skin</li><li>Detecting radicals ex vivo and in vivo in skin using spin probes and spin traps</li><li>Examples of redox status and oxidative stress in skin and plasma using EPR</li></ul><p><strong>Who Should Attend?</strong></p><ul><li>Academics and MDs who do any kind of skin and blood plasma research</li><li>General, R&amp;D and Qc/QA managers, and industrial customers from the health and personal care industries involved in development of skin care products</li></ul><blockquote><p><strong>Presenter: </strong>Prof. Dr. Martina Meinke (Head of the Center of Experimental and Applied Cutaneous Physiology (CCP), Charité – Universitätsmedizin Berlin)</p><p>Prof. Martina.

Since 2007, she is an Assistant Professor of medical physics with the main focus on spectroscopy of blood and skin and electron paramagnetic resonance measurements in skin. She has headed the EPR (electron paramagnetic resonance) spectroscopy group for over 10 years. This method has already been used in several clinical and scientific studies to investigate the formation and characterization of radicals. She also focuses on optical, non-invasive techniques that are widely used for skin examinations.</p><p>Prof. Meinke is author of more than 200 peer reviewed publications and numerous book chapters. She is a member of the Ethics Committee of the Charité and a reviewer for the BMBF VIP+ and the DFG.</p><p><strong>Presenter:&nbsp;</strong>Dr. Silke Lohan (Deputy Head of the Center of Experimental and Applied Cutaneous Physiology (CCP), Charité – Universitätsmedizin Berlin)</p><p>Dr. Silke Lohan was born in Berlin and studied biology at the Free University of Berlin. In 2013, she completed her dissertation (Dr. rer. nat.) in human genetics. She had done her doctoral thesis at the Institute of Medical Genetics and Human Genetics at Charité - Universitätsmedizin Berlin and at the Max Planck Institute for Molecular Genetics. In October 2013, Dr. Lohan joined the team at CCP. Her main interest is electron paramagnetic resonance spectroscopy (EPR), which she applies in vivo, ex vivo and in vitro to study and assess the evolution of radicals in tissues and cells with and/or without the application of stressors. The radicals can be quantified and characterized. In addition, nanoparticle penetration and drug release processes in skin can be studied.</p><p>Currently, she is focusing on projects related to the development and clinical application of UV-LEDs. Here, the focus is on the development of a method to determine the redox status in skin and blood. In addition, a measurement method is being established to investigate the effect of pollutants and the protective effect of anti-pollutant products on the skin.</p><p><strong>Presenter:&nbsp;</strong>Dr. Sylwia Kacprzak (Market Product Manager)</p><p>Sylwia Kacprzak received her M.Sc. degree in Chemistry at the University of Maria Curie Sklodowska in Poland. Her EPR career began during her Ph. D. research at the University of Würzburg with a focus on investigations of the electron paramagnetic resonance parameters of bioradicals by density functional methods. Two postdoctoral positions followed at FU Berlin and University of Freiburg, where she gained extensive expertise in CW-EPR and FT-EPR techniques taking advantage of her theoretical background. In 2016, Sylwia joined Bruker as an Applications Scientist.</p></blockquote>
