Screening of magnetic field by self-assembled mammalian and fungi microtubules.
Show summary
Microtubules are essential structural elements in living organisms, which form scaffolding of the cells and participate in transport of proteins and separation of chromosomes [1]. They are highly ordered nanotubes built of two types of tubulin proteins, and filled with water [2]. It was suggested that additionally to the transport and mechanical functions, microtubules are crucial for the processing of information [3]. Moreover, this processing is considered to be quantum-mechanical [3] and even based on superconductivity [4]. Previously, screening of the magnetic field, which supports superconductivity, has been observed by the magnetic force microscopy in the microtubules assembled from the mammalian tubulin [5]. Here the study is extended to the fungi self-assembled microtubules. In spite of observed structural differences between the mammalian and fungi microtubules, both display full screening of magnetic field. The temporal scans reveal steady screening in the mammalian microtubules and a fluctuating screening in the fungi microtubules. The formation of links between the microtubules and their implication for the processing of information is discussed.

Superconductivity offers absolute zero of resistance and complete expulsion of magnetic flux. It is very valuable for technological applications. Its top achievement is in quantum computing. The unprecedented power of the brain suggests quantum-mechanical processing of information too. Here a search for superconductivity, on which quantum processing of information in living organisms could be based, is presented. Evidences of room-temperature superconductivity in biological systems are given. Implications for explaining consciousness and exchange of information using coherent infrared radiation will be discussed. Demonstrations of superconductivity are offered.

Self-assembled microtubules: a possible quantum “grey matter” for artificial intelligence .
Show summary
It is believed that living organisms process information quantum-mechanically using microtubules [1,2]. In [2], this process is linked to superconductivity. Here experiments are reported, which directly visualize self-assembly of the microtubules in an extract from a mammalian brain and a fungi. The evidence of superconductivity is presented. The influence of nanoparticles on the self-assembly and the possibilities to use the network of the self-assembled microtubules as a “grey matter” for artificial intelligence will be discussed.

Controlling dendritic flux avalanches by nanostructure of superconducting films.
Show summary
Niobium Nitrate (NbN) superconducting films are extensively used in superconducting electronics, for example as basic element of single-photon microwave resonators. Here we report on direct visualisation of magnetic flux penetration into a NbN thin film deposited by High-Temperature Chemical Vacuum Deposition (HTCVD). The film is of the thickness of 90.8 nm. It is deposited at temperature of 1200 C on a single-crystal α-Al2O3 (0001) c-axis substrate (sapphire). The visualisation is done by Magneto-Optical imaging allowing to see directly distribution of magnetic flux in the superconductor. It is found that at low temperatures magnetic flux penetrates into the film in the form of dendritic flux avalanches. Moreover, the shape of dendritic avalanches appeared to be very unusual, previously not reported in the literature. The branches of avalanches persistently follow one specific direction in the plane of the film. To clarify the origin of this effect, high-resolution Scanning Electron Microscopy and Atomic Force Microscopy have been used in combination with the Fast Fourier Transform of the obtained images. It was found that the origin of the selected direction in the dendritic flux penetration is deep on the nanometre scale, namely in nano-channels formed by the merging NbN crystallites during their growth. In this way, nanostructure of the film directly controls dendritic flux avalanches in the superconductor. Varying conditions of deposition would allow actively changing superconducting properties of the films.

Imaging Magnetic Domain Structure of a High Entropy Alloy: Effect of Applied Magnetic Field.
Show summary
High-Entropy Alloys (HEAs) are recently introduced materials consisting of numerous—at least five—elements in nearly equal-atomic concentrations. Studying them, previously unexplored phase fields in multidimensional phase diagrams are now being explored. The HEA concept is based on a thermodynamic balance between mixing entropy and enthalpy, which defines values of several critical parameters that determine the formation of simple or complicated phases. Physical properties, like magnetism, are of great interest for these materials, even though they have not been extensively analyzed so far. Particularly, the exploration of the magnetic domain structure and its correlation with the micro- and nano-structural features of the materials is of high scientific value. In this work, we study the influence of the magnetic history on the alteration of the magnetic domain patterns in polycrystalline FeCoNiAl0.9Mn0.9 High Entropy Alloy (HEA). For the study, we introduce a combinatorial method of Electron Backscatter Diffraction and Magnetic Force Microscopy imaging, which reveals specific magnetic domain structures in the grains of different crystallographic orientations. It is found that in the HEA polycrystal, an increase of the applied magnetic field affects the formation of magnetic domains and leads to a transition from a labyrinth-like pattern to a dotted domain configuration, which is expressed differently in the differently oriented grains.

Ideal diamagnetism in brain microtubules.
Show summary
With mounting evidences of superconductivity in brain microtubules, a key experiment to support its existence would be a nanometer-scale mapping of microtubule magnetic properties. Magnetic force microscopy is a convenient instrument to perform such mapping. Previously, it has been used qualitatively resulting in the detection of strong diamagnetic response coming from the in-plane bundles of microtubules. This was preliminary associated with the feature of ideal diamagnetism and therefore superconductivity in the microtubules. Numerical arguments, however, were absent and it was unclear in what substance superconductivity resides. In order to clarify this, magnetic force microscopy was extended to force spectroscopy, which records magnetic signal as a function of distance from the surface. Moreover, the magnetic force microscopy was performed on cross-sections of microtubules investigating them individually. In order to do this, a special technique of sample preparation has been developed allowing orienting microtubules perpendicular to the substrate. The magnetic mapping revealed strong diamagnetism coming from the inside of microtubules. The analysis of recorded force spectroscopy curves has been performed analytically separating magnetic and van der Waals contributions to the signal. Following this, estimation of the signal expected for ideal diamagnetism has been obtained and compared with the signal coming from the microtubules. It is concluded that microtubules display the property of ideal diamagnetism. The substance, in which superconductivity develops, is likely to be the structured water.

Liquid Hydrogen and Use of Superconductors – a synergy
.
Show summary
Nowadays, sustainable energies become more and more important to eliminate carbon-emission fuels. Hydrogen is one of the most desirable options since water is the only by-product of hydrogen consumption, and it has the highest specific energy (142 MJ/ kg) among all fuels. In contrast, hydrogen has a low volumetric energy density. To compensate for this problem, it is possible to provide hydrogen in liquid form. The boiling point of hydrogen is too low being 20 K (-253 ℃), therefore many might believe that it is a barrier to using it in industry. On the contrary, the low temperature of liquid hydrogen allows one to introduce superconductivity to the hydrogen industry. Superconductivity is the phenomenon of the resistivity-free feature of some materials for passing electricity. Superconductors are only operated at very low temperatures, but hopefully, some superconductors' critical temperature is above the boiling point of liquid hydrogen. This means that liquid hydrogen could be used as a coolant for the superconductors before it is implemented as a fuel. Superconductors lead to using less amount of energy due to their high efficiency and, consequently, have an abatement cost in the energy sector. The maritime industry in Norway aims to design vessels operating with liquid hydrogen, thus it might be the best time to use superconductors to make both technology more economic and efficient.

Superconductivity in living organisms.
Show summary
Superconductivity in living organisms, specifically in central nervous system and brain, was suggested as early as in 1972 by E. Halperin and A. Wolf [1]. Even before that, in 1964, W. Little developed theoretical model for room-temperature superconductivity (RTS) in organic chains of molecules linked to specific molecular complexes, which could be present in living organisms [2]. The purpose of possible RTS was first not understood. Neither were experimental evidences present showing its existence.
Situation changed when it became clear that superconductivity is efficient in quantum computing. Currently, functional superconductor-based quantum computers became reality. An opportunity appeared to explain extraordinary power of brain and nervous system. Experiments started too, first with crude electrical transport measurements of brain slices [3], then using more sophisticated nanometre-scale magnetic force microscopy [4]. The latter was intended to check ideal diamagnetism in brain nano-structures. A conclusion was made that superconductivity is likely to reside in microtubules: highly ordered quasi one-dimensional nanometre-size structures somewhat reminding those suggested by W. Little [2]. The estimate of critical temperature in brain tissue was made [3] and it was found to be close to that predicted by W. Little [2]. A concept of based-on-superconductivity quantum processing of information in living organisms was put forward [5].
In this work, new experimental evidences of RTS are given extending abilities of magnetic force microscopy to measuring cross-sections of microtubules.

Nano superconductivity and quantum processing of information in living organisms .
Show summary
With the advance of superconducting quantum computing and the attempts of extending its operating range to higher temperatures, a special attention is paid to nanostructured quantum circuits. In particular, quasi one-dimensional quantum wires with phase slip centers are argued to be promising structures for the next generation of quantum computers. In its turn, this stimulates revisiting the question about the possibility of quantum processing of information in quasi one-dimensional structures in the nervous system, specifically the brain, in living organisms, especially in the light of recent findings that suggest robust room-temperature superconductivity in these structures. The early theories of superconductivity were in favor of its quasi one-dimensional nature, and the recent findings suggest that reducing dimensions of a system could be a good approach for increasing the critical temperature of a material. Here, based on experimental data, it is 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 may take place in them, are discussed. The role of Josephson oscillations in processing and exchange of information is emphasized.

Nanoscale Magnetic Properties of Additively Manufactured FeCoNiAlxMnx High-Entropy Alloys.
Show summary
Magnetic properties of High-Entropy Alloys based on the Fe-Co-Ni-Al-Mn system are reported. High-Entropy Alloys are cutting-edge technological materials containing five or more elements in relatively high concentrations (5–35 at.%) within one or several solid-state solutions. These solutions are stabilized at the nanometer scale due to the high contribution of the mixing entropy to the Gibbs free energy, which can overcome the enthalpic contribution. Two magnetic alloys are found in FeCoNiAlxMnx (1.6 at.% x 7.8 at.%) samples processed by laser metal deposition. The magnetic techniques used to screen the materials were magneto-optical imaging and magnetic force microscopy. The former allows characterizing magnetic properties within the mm-μm scale, while the latter is efficient down to the nanometer scale. Magnetic screening confirms the importance of the nanostructure in defining magnetic properties of the alloys, and the trends in the magnetic behavior as a function of the alloy composition are revealed. The experimental results suggest that it is possible to form unique alloys, which may outperform conventional magnetic materials used in a variety of applications such as transformers, screening shields and wind power generators.

Probing van der Waals and magnetic forces in bacteria with magnetic nanoparticles.
Show summary
Bioinspired metal-based nanoparticles have potential uses in many applications, but before a possible commercial exploitation, it is important to clarify the pathways of their production and deposition inside the organisms, for example in bacteria. The technique of magnetic force microscopy (MFM) could be used to evaluate the nanoparticles magnetic properties, in addition to allowing tracing their location inside or outside of bacteria, which could help to understand pathways of their biosynthesis. In this work, using MFM and analyzing the interaction of magnetic tip with nanoparticles and bacteria imbedded in resin 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. For these nanoparticles, the interplay between magnetic and van der Waals forces is described at small distances to the surface. Experimental data are 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.

Sequential magnetic mapping of bacteria loaded with Pd-Fe nanoparticles .
Show summary
Magnetic nanoparticles are of widespread use in nanotechnology. One of the most unusual are magnetic palladium nanoparticles that combine magnetism with high catalytic activity. These nanoparticles could be obtained biologically by exposing bacteria to a palladium salt. Due to their small size and weak magnetism, however, it is challenging to measure their magnetic properties. One of the solutions to enhance their magnetism is to incorporate a small amount of iron atoms into them. After this procedure, the nanoparticles together with bacteria can be embedded in resin and characterized by the technique of magnetic force microscopy. This technique allows imaging cross-sections of the bacteria with nanoparticles, but cannot give information from the depth of the sample. Here we report on an approach partially solving this problem. Its novelty lies in measurements of consecutive thin slices of resin, which allows mapping cross-sections of individual bacteria and different parts of the material surrounding the same bacterium. An interesting observed feature is the formation of magnetic chains of nanoparticles outside of the bacteria.

A search for room temperature superconductivity.
Show summary
There is impressive progress in increasing critical temperature (Tc) of superconducting compounds. With the recent discovery of superconductivity at high pressure in H3S with Tc of 203 K [1], the prospects of finding room temperature superconductivity become quite realistic. The important pathways for synthesis of compounds with high Tc were outlined in [2]. The conclusion of the paper is that the highest probability of discovering room temperature superconductivity is in hydrated, to which H3S belongs too. The specifics of hydrates is that pairing interaction is provided by high-energy optical, in addition to acoustic, phonons [3]. Presence of light elements like hydrogen is crucial for high Tc.
Another way to reach Tc above room temperature is to use electron-electron rather than electron-phonon pairing interaction. This was demonstrated by Little in his theoretical model [4]. Additional to employing electron-electron interaction, important assumption of [4] is to use a low-dimensional quantum system. Early search for new superconductors in three-dimensional (3D) materials did not give particular high Tc until a quasi-2D class of materials was discovered by Bednorz and Mueller [5]. Quasi-1D organic systems with specific pairing interaction [4] promise much higher Tc, up to 2200 K.
Knowing this tendency and following general idea suggested in [6] that if room-temperature superconductivity exists, it should be in a system with high level of organization, i.e. nervous system and brain, electrical measurements of brain slices were performed [7]. In these measurements, the idea to use graphene as room-temperature quantum mediator was utilized [8]. The brain is composed of neurons containing microtubules, which are quasi-1D organic structures that might be responsible for superconductivity.
The results of electrical measurements of brain slices will be reported. The estimated from the measurements Tc is close to that predicted in the model of Little [4].
