In our previous study, we suggested a synthetic method for the replication of PCPOSOS (Pb10−xCux[P(O1−y Sy )4]6O1−z Sz ) and showed precisely measured zero resistance. Through the synthesis method we named Daecheol-Mingi (DM) method, we measured the phenomenon of superconductivity phase transition depending on temperature. Also, we repeated validation of zero resistance of the samples. This paper presents a specific critical temperature for PCPOSOS, demonstrating consistency with the original authors’ data.

The BCS theory explains the superconducting properties of Class I conventional metal and alloy superconductors, but it cannot interpret the superconducting phenomenon of Class II unconventional superconductors. The BCS theory violates Coulomb’s law and Heisenberg’s uncertainty principle, and its microscopic mechanism of electron-phonon coupling is essentially wrong. Based on the elastic collision theory of Newtonian classical mechanics, this paper proposes the electron elastic collision superconductivity theory, which reveals that the microscopic mechanism of superconducting states is that the free electrons in a current-carrying wire only undergo complete elastic collisions with the atomic lattices, and the current-carrying wire shows zero-resistance superconducting states. The electron elastic collision superconductivity theory proposes the superconducting state free electron critical speed VC, and theoretically derives the formula for calculating the critical temperature TC: 2 ΔE = 3.7 kB TC. The critical kinetic energy ΔE of the free electron is equal to the minimum phonon energy hγ of the atomic lattice vibration. There is no heat conduction diffusion in the superconducting current-carrying wires, so there are no phonons in the superconductors. The electron elastic collision superconductivity theory interprets the microscopic mechanism of the superconducting state critical temperature TC, the critical magnetic field HC, the critical current density jC, the superconducting state energy gap and the high-pressure superconductor. Unlike Class I conventional superconductors, Class II unconventional superconductors have anisotropic lattices. There are different critical speeds VC, different critical temperatures TC and different critical magnetic fields HC in different directions. Based on the Electron elastic collision superconductivity theory, it is feasible to achieve a zero-resistance superconducting state at normal temperature. Unconventional two-dimensional thin film superconductors and one-dimensional carbon fiber superconductors are the development direction of normal temperature superconductors.

Under typical circumstances, it is commonly believed that solutions carrying a single type of charge are either non-existent or unstable. We have investigated the principles of high-concentration charged solution preparation techniques, employing methods such as electrostatic attraction, gravity separation, positive feedback, and self-powered mechanisms to effectively separate anions and cations in solution. Through electrostatic repulsion and the use of electrostatic separation networks, the partition of homoelectric ions has been achieved. Through water and electric separation, the capability for sustained accumulation of single-charge species has been attained, thus overcoming application bottlenecks and establishing evidence for the existence of charged solutions. We have proposed voltage limits and predicted phenomena such as electrostatic boiling, topological ice crystals, and strange ice crystals, thereby opening new perspectives and possibilities for enriching the understanding and research of electrostatics and electrochemistry. The introduction of the high-concentration charged solution and its controllable preparation are expected to facilitate or pioneer research in various fields including seawater desalination, wastewater treatment, hydrovoltaic power generation, and topological ice crystals, etc. This advancement holds the potential to rectify relevant discussions in textbooks. Implementing the dual electrostatic method for self-powered desalination and purification, coupled with wind, solar, and pumped hydro storage technologies, can aid in mitigating the intermittency and waste of wind and solar power, thus advancing the cause of seawater for land.

The author provides a literature study showing that the residual resistivity and the normal state resistivity at the superconducting transition might be fractionally quantized. Surprisingly, fractional quantized resistivity is observed in the absence of strong magnetic fields. The presented phenomenological classification of 280 single crystals is based on six universal resistivity quanta that are only dependent on natural constants.

We have developed a new synthesis method for producing the Pb-Cu-P-S-O compound samples in order to replicate zero resistance of the PCPOSOS (Pb10−xCux[P(O1−ySy)4]6O1−zSz), which we refer to as the Daecheol-Mingi (DM) synthesis method. The potential zero resistances of the samples were observed through I-V measurements.

We study the Chinese head entries of the Langenscheidt's Pocket Chinese Dictionary written in Pinyin, a Romanized pronunciation system.We draw the natural logarithm of the number of head entries, normalised, starting with a letter vs the natural logarithm of the rank of the letter, normalised(unnormalised). We find that the head entries underlie a magnetisation curve of a Spin-Glass in the presence of little external magnetic field.
