High-entropy alloy (HEA) superconductors-a new class of functional materials-can be utilized stably under extreme conditions, such as in space environments, owing to their high mechanical hardness and excellent irradiation tolerance. However, the feasibility practical applications HEA superconductors has not yet been demonstrated because critical current density (Jc) for adequately characterized. Here, we report fabrication high-quality superconducting (SC) thin films Ta-Nb-Hf-Zr-Ti HEAs via...

A 29-year-old woman with papillary thyroid cancer underwent thyroidectomy and parathyroid auto-transplantation. One month after surgery, the patient received radioiodine therapy. Two days 131 I administration, localized uptake in right sternocleidomastoid muscle was detected by post-therapy whole-body scintigraphy. We found that area colocalized at site of transplantation.

Two different bands with laccase activity were obtained after nondenaturing PAGE of the culture filtrate Pleurotus ostreatus. Immunoblot analysis revealed that antisera raised against I not reactive to II. Laccase I, which exhibited faster mobility on polyacrylamide gel, was purified 42.9-fold an overall yield 10.8%. Gel filtration and SDS-PAGE is a single polypeptide molecular mass approximately 64 kDa. contained 12.5% carbohydrate by weight 3.9 mol copper (mol protein)-1. The absorption...

Abstract We investigate the effect of disorder on superconducting mechanism MgB 2 thin films using low-energy ion irradiation. The c -axis lattice constant and T change systematically as magnitude disorder, which corresponds to value average displacements per atom ( dpa avg ), increases. Here, is controlled by amount irradiated ions. dependence electron–phonon coupling constants λ ) estimated McMillan equation. For ⩽ 0.049, linearly proportional . On other hand, for > disordered deviates...

High-entropy alloy (HEA) superconductors characterized as having a high mixing entropy have attracted substantial interest because of their remarkable potential for technological applications. However, the superconducting (SC) gap HEA superconductors, which is one important factors designing SC devices, has scarcely been studied. Herein, we report direct observation fully gapped pairing symmetry superconductor...

We investigate the effect of ion irradiation on MgB 2 thin films with small grains approximately 122 nm and 140 nm. The flux pinning by grain boundaries is insignificant in pristine due to good inter-grain connectivity, but significantly improved after 120-keV Mn–ion irradiation. scaling behavior force density for ion-irradiated nanoscale demonstrates predominance boundaries, contrast single-crystalline where normal point was dominant low-energy These results suggest that irradiation-induced...
