Biophysical Reviews’ “Meet the Councilor Series”—a profile of Peter Pohl

It is my pleasure to write a few words to introduce myself to the readers of Biophysical Reviews as part of the “Meet the Councilor Series.” Currently, I am serving the second period as IUPAB councilor after having been elected first in 2017. Initially, I studied Biophysics in Moscow (Russia) and later Medicine in Halle (Germany). My scientific carrier took me from the Medical School of the Martin Luther University of Halle-Wittenberg, via the Leibniz Institute for Molecular Pharmacology (Berlin) and the Institute for Biology at the Humboldt University (Berlin) to the Physics Department of the Johannes Kepler University in Linz (Austria). My key research interests lie in the molecular mechanisms of transport phenomena occurring at the lipid membrane, including (i) spontaneous and facilitated transport of water and other small molecules across membranes in reconstituted systems, (ii) proton migration along the membrane surface, (iii) protein translocation, and (iv) bilayer mechanics. Training of undergraduate, graduate, and postdoctoral researchers from diverse academic disciplines has been—and shall remain—a consistent part of my work.

Preface

Seminar Nasional Fisika (SNF) 2021, Universitas Negeri Surabaya on New Adaptations in Physics Learning and Research to Realize an Independent Learning Program Dwikoranto, A Zainuddin, B K Prahani, N P Putri, N A Lestari, U A Deta* Physics Department, Universitas Negeri Surabaya, Indonesia *E-mail: [email protected] We want to present the National Physics Seminar or Seminar Nasional Fisika (SNF 2021), entitled New Adaptations in Physics Learning and Research to Realize an Independent Learning Program. SNF 2021 took place virtually by using the ZOOM meeting because of the COVID-19 pandemic. As we know, the Covid-19 pandemic has harmed almost all areas of life, including education, especially universities. SNF 2021 organized by the Physics Department, Universitas Negeri Surabaya-Surabaya on October 18, 2021. In general, there are two sessions, namely plenary and parallel. The plenary session was given to three keynote speakers: (1) Prof. Dr. Heri Sutanto, M.Si. (09.40-10.10 AM), (2) Dr. Asnawi, M.Si. (10.10-10.40 AM), (3) Prof. Dr. Budi Jatmiko, M.Pd. (10.40-11.10) which ends with a Q&A session (11.10-11.40 AM). Parallel session is for authors who present their papers and is carried out in eight groups of breakout rooms (1.00-4.00 PM). As a scientific forum, the SNF 2021 is attended by 217 participants from students, teachers, lecturers, engineers, and practitioners who participate either as presenters or as participants. The SNF 2021 main aim is to share ideas and knowledge and build collaboration with each other. We received 56 papers that will be selected to be published in the Journal of Physics: Conference Series with the scope of physics and its related area. In this volume, we accept 32 papers for publication after meeting the scope, checking originality, and performing peer review. The technology needed to deliver the meeting successfully is zoom meeting, laptop, sound system, Wi-Fi (internet signal source), and the backup of electrical power. In this particular case, we have two times electricity outages (± 3 minutes). It is not a big problem because we have the backup of electricity and internet signal. We are hoping that the event will become a foothold of thinking in welcoming global developments. In addition, publications packaged in this seminar will further strengthen the existence and reputation of the physics department as an educational institution that excels in scientific publication at national and international levels. The results of these studies need to be disseminated so that they are scientifically helpful and provide practical value for the community. The organizing and editorial committee of the SNF 2021 hopes you enjoy reading this volume of the JPCS. Besides, we would like to fully respect keynote speakers and all the presenters for providing their valuable contributions for this proceeding and the reviewers for their constructive recommendations and criticism aiding to improve the presented articles. We, on behalf of the committee of the SNF 2021, would like to thank all parties for their participation in supporting this publication. We want to invite the participants back to participate in SNF 2022, which will be held by the Physics Department, Universitas Negeri Surabaya.

Pre-flight qualification tests of the Mini-EUSO telescope engineering model

Mini-EUSO is part of the JEM-EUSO program and operates on board the International Space Station (ISS). It is a UV-telescope with single-photon counting capability looking at nighttime downwards to the Earth through a nadir-facing UV-transparent window. As part of the pre-flight tests, the Mini-EUSO engineering model, a telescope with 1/9 of the original focal surface and a lens of 2.5 cm diameter, has been built and tested. Tests of the Mini-EUSO engineering model have been made in laboratory and in open-sky conditions. Laboratory tests have been performed at the TurLab facility, located at the Physics Department of the University of Turin, equipped with a rotating tank containing different types of materials and light sources. In this way, the configuration for the observation of the Earth from space was emulated, including the Mini-EUSO trigger schemes. In addition to the qualification and calibration tests, the Mini-EUSO engineering model has also been used to evaluate the possibility of using a JEM-EUSO-type detector for applications such as observation of space debris. Furthermore, observations in open-sky conditions allowed the studies of natural light sources such as stars, meteors, planets, and artificial light sources such as airplanes, satellites reflecting the sunlight, and city lights. Most of these targets could be detected also with Mini-EUSO. In this paper, the tests in laboratory and in open-sky conditions are reported, as well as the obtained results. In addition, the contribution that such tests provided to foresee and improve the performance of Mini-EUSO on board the ISS is discussed.

Development of neutron scattering kernels for cold neutron reflector materials

The newest neutron scattering applications are highly intensity-limited techniques that demand reducing the neutron losses between source and detectors. In addition, the nuclear industry demands more accurate data and procedures for the design and optimization of advanced fission reactors, especially for the treatment of fuel and moderator materials. To meet these demands, it is necessary to improve the existing calculation tools, through the generation of better models that describe the interaction of neutrons with the systems of interest. The Neutron Physics Department at Centro Atomico Bariloche (CNEA, Argentina) has been developing over the time new models for the interaction of slow neutrons with materials, to produce scattering kernels and cross section data in the thermal and cold neutron energy region. Besides the studies carried out on neutron moderators, we have recently begun looking at materials that could serve as efficient neutron reflectors over those energy ranges. In this work we present the results of transmission and scattering experiments on diamond nanopowder and magnesium hydride, carried out simultaneously at the VESUVIO spectrometer (ISIS, UK), and compare them with newly generated cross-section libraries.

Theoretical Efficiency and Practicality of the Solar Trough Collector / Tikrit-Iraq

An experimental and theoretical study was conducted to attain solar collectors’ thermal efficiency. Testing was done during May of 2019 on a solar collector’s surface at the Physics Department of the University of Tikrit. The absorbent tubes used had a length of 1.5 m, were painted black, made of copper, had an outer diameter of 0.03 m, internal diameter of 0.028 m, and a tank capacity of 40L. By entering these specifications along with those of the solar collector, the theoretical thermal efficiency was calculated. The findings showed that practical efficiency curves and useful thermal energy absorbed by the water contained goes down when using copper tubing. The results also illustrated that useful thermal energy and thermal efficiency increases along with increasing the mass flow rate of water.
