Recently, Mikheenko has been writing many papers on research he's undertaking on the - cylindrical, helix-like - microtubule, where, by different experiments he's designed, he attempts to build evidence for the presence of warm/wet superconductivity within microtubules. Some of his papers are published, some are not. He's produced some really interesting results, and some enlightening speculations in his papers.
One of the signals for potential super-conductivity in materials, is their ability to screen magnetic fields.
In an Experiment (below) published at the 2023 iEEE conference, Mikheenko uses Magnetic force microscopy, together with a phase shifted technique to produce phase shifted image maps comparing mammalian microtubules with fungal microtubules. By convention, the phase shifted image map technique he uses shows areas with negative gradients of magnetic forces as dark. Therefore, magnetically screened areas are expected to be bright. This is interesting work.
The two images below show the bright areas of magnetically shielded microtubules. The upper image shows the more ordered mammalian microtubules. The lower image shows the more disordered fungal microtubules.
