Highlights and Announcements for the M. Smoluchowski Institute of Physics

The first-ever positronium image of a phantom made of heart myxoma and adipose tissue- publication in Science Advances.

Tomograf PETOur collegues Colleagues from the Department of Experimental Particle Physics and its Applications and the Department of Medical Physics of our Institute made the first positron imaging of a phantom made of heart myxoma and adipose tissue.

In vivo assessment of cancer and precise location of altered tissues at initial stages of molecular disorders are important diagnostic challenges. Positronium is copiously formed in the free molecular spaces in the patient’s body during positron emission tomography (PET). The positronium properties vary according to the size of inter- and intramolecular voids and the concentration of molecules in them such as, e.g., molecular oxygen, O2; therefore, positronium imaging may provide information about disease progression during the initial stages of molecular alterations. Current PET systems do not allow acquisition of positronium images. This study presents a new method that enables positronium imaging by simultaneous registration of annihilation photons and deexcitation photons from pharmaceuticals labeled with radionuclides. The first positronium imaging of a phantom built from cardiac myxoma and adipose tissue is demonstrated. It is anticipated that positronium imaging will substantially enhance the specificity of PET diagnostics.

J-PET group has tested symmetry between charged leptonic matter and antimatter - paper in Nature Communications.

Charged lepton system symmetry under combined charge, parity, and time-reversal transformation (CPT) remains scarcely tested. Despite stringent quantum-electrodynamic limits, discrepancies in predictions for the electron–positron bound state (positronium atom) motivate further investigation, including fundamental symmetry tests. While CPT noninvariance effects could be manifested in non-vanishing angular correlations between final-state photons and spin of annihilating positronium, measurements were previously limited by knowledge of the latter. Here, we demonstrate tomographic reconstruction techniques applied to three-photon annihilations of ortho-positronium atoms to estimate their spin polarisation without magnetic field or polarised positronium source. We use a plastic-scintillator-based positron-emission-tomography scanner to record ortho-positronium (o-Ps) annihilations with single-event estimation of o-Ps spin and determine the complete spectrum of an angular correlation operator sensitive to CPT-violating effects. We find no violation at the precision level of 10−4, with an over threefold improvement on the previous measurement.

Frans Habraken Best Paper Award 2021 for Dr. Katarzyna Gajos

Award certificate

I am delighted to inform you that the editors of the Applied Surface Science journal (IF = 6.707) honored Dr. Katarzyna Gajos with the "Frans Habraken Best Paper Award 2021" for the work "Surface density dependent orientation and immunological recognition of antibody on silicon: TOF-SIMS and surface analysis of two covalent immobilization methods ”(DOI: 10.1016 / j.apsusc.2020.146269).

This award, commemorating Professor Frans Habraken, longtime editor of Applied Surface Science, has been awarded annually since 2014 to the first (or corresponding) author, aged up to 30, of the best scientific article published in this journal in the previous year. When choosing, the team of editors is guided by criteria such as the originality of the work, its scientific significance, and the interest of readers.

The distinguished work describes the research carried out by the team from the M. Smoluchowski Institute of Physics at the Jagiellonian University, composed of dr Katarzyna Gajos, mgr Klaudia Szafraniec, prof. dr hab. Andrzej Budkowski, in collaboration with Dr. Panagiota Petrou from NCSR DEMOKRITOS from Athens. Using TOF-SIMS Secondary Ion Mass Spectroscopy, the dominant orientation of the detection molecules (antibodies) was determined directly depending on the density of their coverage of the biosensor surface. As the orientation of antibodies is crucial for antigen recognition, the presented studies can help improve biosensors' efficiency and sensitivity by optimizing the methods of coating the biosensor surface with antibodies.

Institute deadline for submitting applications for promotion to the position of university professor

Dear Colleagues,

I would like to inform you that applications for promotion to the position of university professor should be submitted to the secretary's office of the Director of the Institute of Physics of the Jagiellonian University M Smoluchowski with Mr. Alicja Mysłek, by June 1, 2021.

The above date is earlier than the date set by the Dean of WFAIS. However, according to §10 point 1 of the promotion procedure, "The Dean of the Faculty shall submit an application for promotion to the position of university professor from the director of the institute in which the academic teacher who is a candidate for promotion is employed". Therefore, I would like to have time to read the conclusions calmly.

Kind regards

Zbigniew Postawa

/ Director of the Institute of Physics of the Jagiellonian University M. Smoluchowski /

Criteria and procedure of internal promotion to the position of university professor at the Faculty of Physics, Astronomy and Applied Computer Science of the Jagiellonian University.
