recommendations! Published in 2024 at "Advanced Science"

DOI: 10.1002/advs.202408370

Abstract: Hydrogen and hydride materials have long been considered promising materials for high‐temperature superconductivity. However, the extreme pressures required for the metallization of hydrogen‐based superconductors limit their applications. Here, a series of high‐temperature perovskite hydrides is… read more here.

DOI: 10.1002/advs.202512696

Abstract: Hydride superconductors have attracted significant attention, yet achieving superconductivity at ambient pressure remains a key challenge. Here, a family of high‐Tc (superconducting critical temperature, Tc) hydrides based on the fluorite‐type AXH8 structure, exhibiting thermodynamic and… read more here.

DOI: 10.1007/s00296-019-04282-z

Abstract: Nasal biopsy is the essential method for differentiating and diagnosing granulomatosis with polyangiitis (GPA) in patients with chronic rhinosinusitis. Nevertheless, in the real clinical settings, there are several cases unable for nasal biopsy. Hence, in… read more here.

DOI: 10.1007/s00410-018-1475-0

Abstract: We report new experimental data of Cu diffusivity in granite porphyry melts with 0.01 and 3.9 wt% H2O at 0.15–1.0 GPa and 973–1523 K. A diffusion couple method was used for the nominally anhydrous granitic melt, whereas… read more here.

DOI: 10.1007/s00410-020-01731-y

Abstract: Antigorite is considered as the most important source of water in subduction zones, playing a key role during arc magma genesis. Although, these magmas seem more oxidized than mid-oceanic ridge basalts (MORB), the possible inherent… read more here.

DOI: 10.1016/j.carbon.2018.04.021

Abstract: Abstract In this paper, bubble-on-plate structure is realized on hollow IF-MoS2/reduced graphene oxide (HIF-MoS2/RGO) nanocomposites. HIF-MoS2 nanocages templated with the generated ammonia (NH3) are connected to RGO through the interlayered MoS2. The as-prepared HIF-MoS2/RGO is… read more here.
