The research of new superconductors is an ongoing ﬁeld for the fundamental significances and potential applications, and two-dimensional (2D) nanomaterials open a new alluring branch for exploration. Here we predict by ﬁrst-principles calculations that 2D pristine graphene-like BSi monolayer is a phonon-mediated superconductor above the boiling point of liquid helium. The intrinsic covalent-metallic ground state, large density of states at Fermi energy, proper electronic organization as well as strong coupling of out-of-plane phonons and electrons endow an intermediate electron-phonon coupling of ~1.12, render-ing this honeycomb sheet as a conventional superconductor with a relatively high Tc ~11 K. As the glob-al minimum structure in the 2D space previously predicted, this superconducting BSi monolayer may be feasible experimentally. Our finding provides a new field of superconducting nanomaterials for study.

We present a theory of phonon-mediated superconductivity in near magic angle twisted bilayer graphene. Using a microscopic model for phonon coupling to moiré band electrons, we find that phonons gene...
With the enormous research activity focused on graphene in recent years, it is not surprising that graphene superconductivity has become an attractive area of research. To date, no superconducting pro...
Topological materials which are also superconducting are of great current interest, since they may exhibit a non-trivial topologically-mediated superconducting phase. Although there have been many rep...
The data presented in this article are related to "Odd-even phonon transport effects in strained carbon atomic chains bridging graphene nanoribbon electrodes" (Kim et al., 2019). To provide the inform...
It is widely accepted that phonon-mediated high-temperature superconductivity is impossible at ambient pressure, because of the very large effective masses of polarons or bipolarons at strong electron...
This is a single center, prospective, observational study to demonstrate the clinical validity of the Intrinsic LifeSciences (ILS) Intrinsic Hepcidin IDx™ Test in the diagnosis and manag...
Vitamin B12 is an essential nutrient for normal DNA-synthesis and must be supplied by animal products. Vitamin B12 deficiency may cause anemia and irreverible neurological damage. Laborato...
This is a research study of patients with diffuse intrinsic pontine gliomas. We hope to learn about the safety and efficacy of treating pediatric diffuse intrinsic pontine glioma patients...
Nanoparticles (NPs) are minute pieces of material to which we are exposed every day in the air we breathe. Some are naturally occurring and have no impact on health, whereas others are pro...
INTRINSIC RV is a two-armed randomized trial that will compare the effects of innovative dual-chamber pacing with AV Search Hysteresis to standard VVI among ICD patients.
The ability of an element or metallic alloy to allow the passage of ELECTRONS without ELECTRICAL RESISTANCE and expel MAGNETIC FIELDS below a certain threshold temperature called superconducting transition temperature.
A glycoprotein secreted by the cells of the GASTRIC GLANDS that is required for the absorption of VITAMIN B 12 (cyanocobalamin). Deficiency of intrinsic factor leads to VITAMIN B 12 DEFICIENCY and ANEMIA, PERNICIOUS.
A broad category of sleep disorders characterized by either hypersomnolence or insomnia. The three major subcategories include intrinsic (i.e., arising from within the body) (SLEEP DISORDERS, INTRINSIC), extrinsic (secondary to environmental conditions or various pathologic conditions), and disturbances of circadian rhythm. (From Thorpy, Sleep Disorders Medicine, 1994, p187)
A lattice of fibrils which covers the entire inner surface of the nuclear envelope and interlinks nuclear pores (NUCLEAR PORE).
Neoplasms composed of lymphoid tissue, a lattice work of reticular tissue the interspaces of which contain lymphocytes. The concept does not refer to neoplasms located in lymphatic vessels.
