Transmission of Radio‐Frequency Waves and Nuclear Magnetic Resonance in Lanthanum Superhydrides

Advanced Science, Volume 13, Issue 23, 23 April 2026.
1H NMR and radio‐frequency transmission measurements of lanthanum superhydrides at 165 GPa reveals a transition at 260–280 K by a strong suppression of the signal intensity, significant changes in NMR spectra, including a dramatic decrease of the relaxation rate 1/T1T, and pronounced shielding effect, which may have a superconducting nature.

Field Survey of Freshwater Invertebrates Reveals That Several Groups Are Potential Carriers of the Fungal Pathogen Batrachochytrium dendrobatidis

Ecology and Evolution, Volume 16, Issue 4, April 2026.
ABSTRACT The amphibian disease chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), has devastated global amphibian biodiversity. The specific reasons for its rapid global spread, especially to pristine areas, are not well understood. Freshwater invertebrates might function as carriers of Bd, but the diversity and extent

Electrochemical Oxidation of Paracetamol Mediated by MgB2 Microparticles Modified Glassy Carbon Electrode

E-Journal of Chemistry, 2011
A MgB2 microparticles modified glassy carbon electrode (MgB2/GCE) was fabricated by adhering microparticles of MgB2 onto the electrode surface of GCE. It was used as a working electrode for the detection of paracetamol in 0.1 M KH2PO4 aqueous solution ...

Potassium‐Doped Borophane Nanosheets: A Multifunctional Platform for Reversible Hydrogen Storage and Metal‐Free Hydrogen Transfer

Small, Volume 22, Issue 22, 17 April 2026.
Borophane in dual roles: as a reductant in the conversion of levulinic acid to γ‐valerolactone and as a reversible hydrogen reservoir through partial rehydrogenation. ABSTRACT 2D borophene has long been proposed as a promising hydrogen storage material, but experimental demonstrations remain limited to boron hydride sheets derived from MgB2.

Aqueous Lithium Hydroxide Chemistry Based on Hierarchically Assembled Hydrogenated Borophene/Cobalt‐Nickel Compounds for Rechargeable High‐Performance Supercapattery

Advanced Energy Materials, Volume 16, Issue 9, 4 March 2026.
Aqueous lithium‐ion storage has been demonstrated using a hierarchically assembled hydrogenated borophene/cobalt‐nickel compound as a supercapattery electrode. Reducible hydrogenated borophene generates undercoordinated oxygen, which is redox‐active for lithiation and hydrogenation during the discharging process following the lithium hydroxide ...

Microstructural and crystallographic imperfections of MgB2 superconducting wire and their correlation with the critical current density

AIP Advances, 2014
A comprehensive study of the effects of structural imperfections in MgB2 superconducting wire has been conducted. As the sintering temperature becomes lower, the structural imperfections of the MgB2 material are increased, as reflected by detailed X-ray ...
