“…From the point of view of physical theories, it remains unclear whether there is a continuous connection between low-temperature and high-temperature superconductors, since the mechanism of formation of superconducting particles [2,25] should be different. As can be seen from Fig.…”

The most extensive database of superconducting materials has been pre-processed. On this database, methods for reducing dimensions, pairwise display of features, a heat map and Pearson's correlation criterion, visualization of features with color are considered. The dependences of the critical temperature of superconductors on atomic mass, radius, ionization energy, electron affinity, heat of fusion, thermal conductivity, and valence are considered.

“…To this day, the exploration of superconducting materials and the study of the mechanisms of superconductivity are still very important topics in condensed matter physics, and in order to realize widespread applications of superconductors as early as possible in the future finding high-temperature or even room-temperature superconductors has always been a long-term goal of scientists [2,3]. Current superconducting materials are generally categorized into two branches by their production process, one is conventional superconductors that can be explained by Bardeen-Cooper-Schrieffer (BCS) theory, such as metal superconductors and alloy superconductors, the other is unconventional superconductors that cannot be explained by BCS theory, including cuprate superconductors, ironbased superconductors, organic superconductors, and heavy fermionic superconductors [4,5]. BCS theory indicates that the mutual coupling of electrons and phonons via phonon scattering can make two electrons overcome the electrostatic repulsion at low temperatures and form a 'net attraction potential energy'.…”

Superconducting nanofibers have attracted much attention in basic researches and practical applications due to their unique physical properties such as broad phase transition temperature, excellent heat conductivity, and high critical current density, etc. Electrospinning, as a common method to prepare nanofibers, also has many applications for the preparation of superconducting nanofibers. However, a few of the new methods to fabricate superconducting nanofibers via electrospinning still need further investigations. This review firstly introduces several potential electrospinning methods to obtain superconducting nanofibers, then proceeds to summarize the recent progress in the field of electrospun superconducting materials. The preparation process, difficulties and problems, physical properties of the superconducting nanofibers or nanonetworks (such as superconducting transition temperature, critical current density, critical magnetic field strength, fiber morphology, and structure, etc), theoretical analysis of the properties, and the techniques to improve the performance are also reviewed. In addition, some suggestions and prospects for the development and applications of electrospun superconducting materials in the future are discussed.

“…The mechanical properties of the porous materials presented are inferior to those of dense superconductors. An improvement of both mechanical and currentcarrying properties in PSs can be achieved by creating composites with silver [119, 135,136]. To improve the mechanical properties, it was proposed in [13] to impregnate a porous material with rubber.…”

This paper gives a review of studies of superconductors with a porosity above 50%. The pores in such superconducting materials provide refrigerant penetration, efficient heat dissipation and stable operation. Methods for the synthesis of the main groups of porous superconductors are described. The results of studies of the structural, magnetic, and electrical transport properties are presented, and the features of the current flow through porous superconductors of various types are considered.
