Strong performance at international conference on nanomaterials

IEEE 10th International Conference "Nanomaterials: Applications & Properties" (NAP-2020) took place in Ukraine from November 9, 2020 to November 13, 2020.

The conference covered most interesting aspects of modern materials science with the focus on nanoscale materials. It brought together a broad international community of scientists, engineers, and lecturers, who involved in understanding and controlling the matter at the nanoscale, which leads to revolutionary technological and industrial advances. The conference covered a wide variety of topics including biotechnology aspects of nanoscience.

The conference featured renowned invited and contributing speakers of wide geography representing 25 countries, including USA, UK, Germany, France, Italy, China, Sweden, Finland and Norway. Total number of participants was about 250. Norway was presented by a group from the University of Oslo [1-4].  Four oral presentation were given by the group, covering nearly 10% of all contributed oral presentations.  

PhD student Ana Lucia Campaña, MS student James Claxton and Professor Pavlo Mikheenko

In her impressive presentation [1], which reached final in the competition for the best presentation, PhD student Ana Lucia Campaña (BEDPAN project, Principal supervisor Prof. P. Mikheenko) reported details of the magnetic force microscopy (MFM) used to evaluate magnetic properties of Pd nanoparticles recovered by bacteria. Using MFM and analysing the interaction of magnetic tip with nanoparticles at different heights above the surface and comparing gradients of forces recorded by magnetic and non-magnetic tips, a condition was found, which allows to measure pure magnetic response of Pd-Fe nanoparticles. Furthermore, the interplay between magnetic and van der Waals forces was described at small distances to the surface. Experimental data were compared with simulations, based on the calculation of the distribution of magnetic field around a nanoparticle, which defines magnetic force acting on the MFM tip.

In another professional presentation [2], MS student James Claxton (BEDPAN project, Principal supervisor Prof. P. Mikheenko) revealed new technique allowing reconstructing three-dimensional distribution of nanoparticles inside and outside of bacteria. The novelty of the technique lies in MFM measurements of consecutive thin slices of resin, which allows mapping cross-sections of individual bacteria and different nanoparticles surrounding it. An interesting reported feature was the formation of magnetic chains of nanoparticles outside of a bacterium.

In his presentation [3], directly related to Digital Life Norway activities, Professor Pavlo Mikheenko described details of quantum processing of information in living organisms in the quasi one-dimensional structures in the nervous system. This report was based on his recent findings that suggest robust room-temperature superconductivity in such structures [5]. Based on experimental data, it was argued that both room-temperature superconductivity and quantum processing of information are possible in the microtubules that are abundant in the nervous system and form the scaffolding of every cell in advanced living organisms. The origin of superconductivity in microtubules, and the way in which quantum processing of information is likely to take place were discussed. The role of Josephson oscillations in processing and exchange of information was emphasized. The paper [5] is a well-accepted paper of the researcher.
