In Entropy 24, 83 (2022) [1], titled "The Law of Entropy Increase and the Meissner Effect", A. Nikulov claims that the Meissner effect exhibited by type I superconductors violates the second law of thermodynamics. Contrary to this claim, I show that

In Nat Comm. 13,3194 (2022) [1] and an "Author Correction" to it [2], Minkov et al. presented magnetization data versus applied magnetic field for H_3S and LaH_10 under pressure, argued that the data provide evidence that these materials are supercon

I analyze the implications of the recently published "Author Correction" (Nat Commun 14, 5322 (2023)) to a paper by Eremets and coauthors reporting magnetization measurements on hydrides under high pressure (Nat Commun 13, 3194 (2022)) to the underst

In their paper arXiv:2405.08189, Supercond. Sci. Technol. 37 (2024) 065010 [1], Bud'ko et al. present experimental results for trapped magnetic flux for a tiny sample of a type II superconductor. The paper aims to provide evidence in support of the i

In Ref. [1] we surveyed the known hydride superconductors, and compared their resistive behavior to that of typical known superconductors, including conventional (e.g. NbN and MgB$_2$) and unconventional (e.g. YBCO) superconductors, and concluded tha

In Ref. [1], Minkov et al. reported measurements of the magnetic moment that remains after a magnetic field is turned on and then turned off for hydride materials under high pressure in a diamond anvil cell. In Refs. [2,3], Minkov et al. reported mag

In Nat Commun 13, 3194 (2022) [1], Minkov et al. reported magnetization measurements on hydrides under pressure that claimed to find a diamagnetic signal below a critical temperature demonstrating the existence of superconductivity. Here we present a

The resistive transition width of a recently discovered room temperature near-ambient-pressure superconductor [1] changes by more than three orders of magnitude between different samples, with the transition temperature nearly unchanged. For the narr

It has recently been reported that hydrogen-rich materials under high pressure trap magnetic flux, a tell-tale signature of superconductivity [arXiv:2206.14108v1]. Here we point out that under the protocol used in these experiments the measured resul
