“…Thus, after the withdrawal [6] of publication [5], we can say that superconductivity in the mysterious C±S±H system cannot be considered scientifically proven, and superconductivity at room temperature has not yet (alas!) been achieved.…”

“…We present below a brief review of the criticism of the results published by Snyder et al [5], which, together with the withdrawal of the publication itself [6], practically states that there is no room temperature superconductivity in the C±S±H compound, and, accordingly, the achievement of this goal apparently remains a matter for the future.…”

What led to retraction of the article on room-temperature superconductivity in the journal <i>Nature</i>: a series of oversights or falsification?

In 2020, the journal Nature published an article under the notorious title ``Room-temperature superconductivity in a carbonaceous sulfur hydride'' (Nature 586 373±377 (2020)) that caused, without exaggeration, an effect like an exploding bomb; after all, it was stated that one of the most important problems in modern physics (implementation of superconductivity at room temperature) has already been solved! In two years, the article has been cited over 500 times and read over 100,000 times. However, in the scientific community, the article led to a great deal of questions, skepticism, and severe criticism. Eventually, on September 26, 2022, Nature retracted this publication. We give here the main reasons for the retraction and our commentary on the significance of this act for the physics of high-temperature superconductivity in general and the superconductivity of hydrides in particular.

“…The impact of high-pressure (HP) studies on fundamental physics, chemistry, and especially Earth and planetary sciences is enormous. Solids exposed to high pressures reveal numerous complex phenomena, such as metal-to-insulator transitions, 1,2 high temperature superconductivity, [3][4][5] and new "super"-states of matter. [6][7][8] Even under moderated pressure-temperature (PT) conditions, fully unexpected chemical bonding and stoichiometry can be observed.…”

The success of high-pressure research relies on the inventive design of pressure-generating instruments and materials used for their construction. In this study, the anvils of conical frustum or disk shapes with flat or modified culet profiles (toroidal or beveled) were prepared by milling an Ia-type diamond plate made of a (100)-oriented single crystal using the focused ion beam. Raman spectroscopy and synchrotron x-ray diffraction were applied to evaluate the efficiency of the anvils for pressure multiplication in different modes of operation: as single indenters forced against the primary anvil in diamond anvil cells (DACs) or as pairs of anvils forced together in double-stage DACs (dsDACs). All types of secondary anvils performed well up to about 250 GPa. The pressure multiplication factor of single indenters appeared to be insignificantly dependent on the shape of the anvils and their culets’ profiles. The enhanced pressure multiplication factor found for pairs of toroidally shaped secondary anvils makes this design very promising for ultrahigh-pressure experiments in dsDACs.

The resistive transition width of a recently discovered room temperature near-ambient-pressure hydride superconductor [1] changes by more than three orders of magnitude between different samples, with the transition temperature nearly unchanged. For the narrowest transitions, the transition width relative to $$T_c$$ T c is only $$0.014 \%$$ 0.014 % . The voltage-current characteristics indicate vanishing critical current, and the normal state resistance is unusually small. These anomalous behaviors and other issues indicate that this system is not a superconductor. Implications for other hydrides are discussed.
