Smart meta-superconductor MgB2 constructed by the dopant phase of luminescent nanocomposite

Scientific Reports, 2019
On the basis of the idea that the injecting energy will improve the conditions for the formation of Cooper pairs, a smart meta-superconductor (SMSC) was prepared by doping luminescent nanocomposite Y2O3:Eu3+/Ag in MgB2.

Monitoring the Prevalence and Distribution of Chytrid Fungus (Batrachochytrium dendrobatidis) in the Kihansi Spray Toad (Nectophrynoides asperginis) Population in the Kihansi Gorge Spray Wetlands, Tanzania

Ecology and Evolution, Volume 16, Issue 1, January 2026.
How to manage the continued impact of Chytrid fungus on Kihansi Spray Toad population in the wild. ABSTRACT Chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), is fatal to some amphibian species, whereas others can carry the pathogen without developing disease.

Differential Conductance Measurements of MgB2-Based Josephson Junctions Below 1 Kelvin

, 2010
Magnesium diboride has many intriguing characteristics, including its relatively high critical temperature and two-band nature. Most prior studies of MgB2 thin film Josephson junctions have been conducted above 2 Kelvin. We report results of sub-1 Kelvin

Anomalous Magnetic Response of Annealed V0.60−xSixTi0.40 Alloys within the Superconducting Phase

physica status solidi (b), Volume 263, Issue 1, January 2026.
Annealed V0.60−xSixTi0.40 alloys exhibit an anomalous magnetic response in their mixed state, where magnetization measured during cooling in the presence of a magnetic field is lower than during warming in the same field. This unusual thermomagnetic response, distinct from conventional type‐II superconductors, is attributed to the high‐field ...

Multifunctional electroless nickel boron composite coatings incorporated by magnesium diboride ceramic particles

International Journal of Ceramic Engineering & Science
In this study, the role of MgB2 in composite coatings is pivotal. Electroless Ni–B plating, a current‐free chemical reduction process, deposits nickel–boron coatings. Other than MgB2, reinforcements like SiC, B4C, and so forth are used with Ni–B coatings

Magneto‐Tunable Thermal Diode Based on Bulk Superconductor

Advanced Physics Research, Volume 4, Issue 12, December 2025.
A thermal diode based on bulk superconducting materials is developed. Using the sharp change in thermal conductivity and its temperature dependence of Pb near the superconducting transition, Pb–Al junction works as a thermal diode with thermal rectification ratio (TRR) of 1.75. The working temperature can be tuned by applied magnetic field.

Ammonothermal Growth of Rhombohedral Boron Nitride

physica status solidi (b), Volume 262, Issue 12, December 2025.
Boron nitride crystals are grown using the ammonothermal technique in a temperature‐induced solubility gradient of BN dissolved in a solution of supercritical ammonia using sodium as the mineralizer. The grown BN crystals harvest off the autoclave walls, and cubic BN seeds are characterized as hexagonal and rhombohedral phases of BN. Boron nitride (BN)
