Superconductivity in Heusler compound ScAu2Al.
Bag B, Loke R, Singh B, Thamizhavel A, Singh B, Ramakrishnan S. Bag B, et al. J Phys Condens Matter. 2022 Mar 8;34(19). doi: 10.1088/1361-648X/ac5651. J Phys Condens Matter. 2022. PMID: 35176733
The field-dependent magnetization response further shows signatures of flux jump in ScAu(2)Al. A sharp jump in the temperature dependent specific heat (C(p)) data confirms bulk superconductivity. We report that the electron-phonon coupling constant,lambda(e-p …

Unconventional spectral signature of Tc in a pure d-wave superconductor.
Chen SD, Hashimoto M, He Y, Song D, He JF, Li YF, Ishida S, Eisaki H, Zaanen J, Devereaux TP, Lee DH, Lu DH, Shen ZX. Chen SD, et al. Nature. 2022 Jan;601(7894):562-567. doi: 10.1038/s41586-021-04251-2. Epub 2022 Jan 26. Nature. 2022. PMID: 35082417
In conventional superconductors, the phase transition into a zero-resistance and perfectly diamagnetic state is accompanied by a jump in the specific heat and the opening of a spectral gap(1). In the high-transition-temperature (high-T(c)) cuprates, although …

Entropic evidence for a Pomeranchuk effect in magic-angle graphene.
Rozen A, Park JM, Zondiner U, Cao Y, Rodan-Legrain D, Taniguchi T, Watanabe K, Oreg Y, Stern A, Berg E, Jarillo-Herrero P, Ilani S. Rozen A, et al. Nature. 2021 Apr;592(7853):214-219. doi: 10.1038/s41586-021-03319-3. Epub 2021 Apr 7. Nature. 2021. PMID: 33828314
We map this jump as a function of electron density, temperature and magnetic field. This reveals a phase diagram that is consistent with a Pomeranchuk-like temperature- and field-driven transition from a low-entropy electronic liquid to a high-entropy correla …

Electrocatalytic Water Oxidation by a Phosphorus-Nitrogen O═PN3-Pincer Cobalt Complex.
Das PK, Bhunia S, Chakraborty P, Chatterjee S, Rana A, Peramaiah K, Alsabban MM, Dutta I, Dey A, Huang KW. Das PK, et al. Inorg Chem. 2021 Jan 18;60(2):614-622. doi: 10.1021/acs.inorgchem.0c02376. Epub 2020 Nov 25. Inorg Chem. 2021. PMID: 33236627
Most importantly, ligand (pseudo)aromaticity is identified to play an important role during electrocatalysis. A significant potential jump (300 mV) was achieved toward a lower positive value when the aromatized cobalt complex was transformed into a (pseudo)dearomatized cob …

Charge-transfer channel in quantum dot-graphene hybrid materials.
Cao S, Wang J, Ma F, Sun M. Cao S, et al. Nanotechnology. 2018 Apr 6;29(14):145202. doi: 10.1088/1361-6528/aaac62. Nanotechnology. 2018. PMID: 29388921
The main MOs are derived from the fragment MOs (FOs) of GR, and the Cd(13)Se(13) QD FOs merge with the GR FOs in a certain proportion to afford the hybrid system. Upon photoexcitation, electrons in the GR FOs jump to the QD FOs, leaving holes in the GR FOs, and the definit …

Hydrates of active pharmaceutical ingredients: A 35Cl and 2H solid-state NMR and DFT study.
Holmes ST, Vojvodin CS, Veinberg N, Iacobelli EM, Hirsh DA, Schurko RW. Holmes ST, et al. Solid State Nucl Magn Reson. 2022 Dec;122:101837. doi: 10.1016/j.ssnmr.2022.101837. Epub 2022 Nov 4. Solid State Nucl Magn Reson. 2022. PMID: 36434925
Specifically, for every case in which such a comparison could be made, we find that the hydrate has a smaller magnitude of C(Q) than the corresponding anhydrous form, indicating a chloride ion environment with a ground-state electron density of higher spherical symmetry in …

They clearly show that Cu(0.03)TaS(2) undergoes a superconducting transition at T(C) = 4.03 K. The obtained superconducting parameters demonstrate that Cu(0.03)TaS(2) is an anisotropic type-II superconductor. Combining specific heat jump deltaC/gamma(n)T(C) = 1.6(4) …
