The Review of Superconductivity in MgB2,-How much was MgB2 Understood?-

Nihon Kessho Gakkaishi, 2004
Since the discovery of high-Tc superconductor MgB2 by our group, a large number of experimental and theoretical works has been performed. The superconductivity in this simple binary alloy is essentially explained within a framework of BCS theory from both sides.

The influence of structural defects on intra-granular critical currents of bulk MgB2

, 2003
Bulk MgB2 samples were prepared under different synthesis conditions and analyzed by scanning and transmission electron microscopy. The critical current densities were determined from the magnetization versus magnetic field curves of bulk and powder ...

High Trapped Fields in C-doped MgB2 Bulk Superconductors Fabricated by Infiltration and Growth Process

Scientific Reports, 2018
The grain boundaries in superconducting MgB2 are known to form effective magnetic flux pinning sites and, consequently, bulk MgB2 containing a fine-grain microstructure fabricated from nanoscale Mg and B precursor powders exhibits good magnetic field ...

Acoustical-Mode-Driven Electron-Phonon Coupling in Transition-Metal Diborides

, 2002
We show that the electron-phonon coupling in the transition-metal diborides NbB2 and TaB2 is dominated by the longitudinal acoustical (LA) mode, in contrast to the optical E_{2g} mode dominated coupling in MgB2.

Spectroscopic Evidence for Anisotropic S-Wave Pairing Symmetry in MgB2 [PDF]

, 2001
Scanning tunneling spectroscopy of superconducting MgB$_2$ ($T_c = 39$ K) were studied on high-density pellets and c-axis oriented films. The sample surfaces were chemically etched to remove surface carbonates and hydroxides, and the data were compared ...

Investigating possible kinetic limitations to MgB2 hydrogenation

International journal of hydrogen energy, 2019
An investigation is reported of possible kinetic limitations to MgB2 hydrogenation. The role of H–H bond breaking, a necessary first step in the hydrogenation process, is assessed for bulk MgB2, ball-milled MgB2, as well as MgB2 mixed with Pd, Fe and ...

Endonuclease V: From Transcriptome Regulator to Chemical Biology Tool

ChemistryEurope, Volume 4, Issue 2, February 2026.
Post‐transcriptional modifications play a pivotal role in regulating the health and physiology of human cells, and adenosine‐to‐inosine (A‐to‐I) editing is one of the most abundant of these modifications. Inosine is read as guanosine by the cellular machinery, and this change impacts both the regulation and genetic code of RNA, in turn effectively ...

Rigid vortices in MgB2 [PDF]

Applied Physics Letters, 2003
Magnetic relaxation of high-pressure synthesized MgB2 bulks with different thickness is investigated. It is found that the superconducting diamagnetic moment depends on time in a logarithmic way: the flux-creep activation energy decreases linearly with the current density (as expected by Kim–Anderson model) and the activation energy increases linearly ...
