There were, however, no direct experiments checking such a statement. Recently, strong advancement in quantum computing took place utilizing properties of superconductors at low temperatures. Following this progress, it was proposed that brain microtubules are superconducting at room temperature allowing quantum processing of information. Moreover, the evidence of room-temperature superconductivity in brain slices containing microtubules was obtained by electrical transport measurements, and even specific scenario of quantum processing in the microtubules has been suggested. These results, however, are not yet accepted by the scientific community as there are no known attempts to reproduce them. Another step in proving superconductivity would be confirming ideal diamagnetism of microtubules, since ideal diamagnetism is more fundamental property of superconductivity than perfect conductivity, some features of which were seen indirectly, or the existence of energy gap, which was already confirmed by the transport measurements. Here brain microtubules are examined by the magnetic force microscopy. The evidence of strong diamagnetism and its sensitivity to the water content in the microtubules is obtained. This gives another strong argument in favor of the concept suggesting superconductivity-based quantum processing of information in living organisms.","PeriodicalId":6735,"journal":{"name":"2021 IEEE 11th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86531792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indentation tests show that the surface nanostructuring leads to the ~30% increase in the instrumental hardness of the cryo-UIT processed specimen (HIT ~5.4 GPa) and to a slight increase in elastic modulus (E ~90.5 GPa). The UIT processes also led to an increase in the corrosion potential and a decrease in the corrosion current density indicating the enhanced corrosion resistance in 0.9 NaCl physiological solution.

The radial distribution function is also calculated as a function of the load on the substrate. Internal energy is calculated, for one-layer film with a zero load, such a dependency is irregular with considerable fluctuations. For a higher value of load, periodic spikes are observed. Similar spikes are inherent in experiments when the film is in a solid-like state and they are characteristic to the stick-slip friction.

TiO2 modification with yttrium oxide enhances the degree of antibiotic degradation.

Additional use of an oxidant (H2O2) significantly increases (more than 2 times) efficiency of the photocatalytic process. It has been found that at low concentrations of antibiotic aqueous solution (up to $10 mathrm{mg/dm^{3}}$), its photodegradation over TiO2 modified with yttrium oxide reaches 100%.
