TL;DR: Rationally designed niobium-titanium (Nb-Ti) superconducting joints were fabricated by using a solder matrix replacement method with two types of lead-bismuth (Pb-Bi) solder, including Pb42Bi58 as a new composition and attained a critical current of >200 A below 1.2 K.

TL;DR: In this article, dual sintered commercially available multifilament in situ and laboratory-made internal magnesium diffusion (IMD) processed MgB2 conductors (un-doped and Cdoped) and evaluated their transport performance, microstructure, lattice parameters, and critical temperature in detail.

TL;DR: In this article, an ultra-low resistance superconducting joint using unreacted multifilament MgB2 wires produced by tailoring the powder compaction pressure within the joint with heat treatment conditions was reported.

TL;DR: In this paper, the effects of residual amorphous impurities on the superconducting performance of polycrystalline MgB2 materials with hydrocarbon doping were investigated.

TL;DR: In this paper, a method has been developed for demonstrating a flow nanogenerator by using a mixture of magnetic nanofluid (MNF) and bubbles in a fluid circulating system, and notable phenomena related to the power generation properties of the nanogenator have been explored MNF is widely used in various areas because of its interesting magnetic properties under an external magnetic field.
