Kinetic Enhancement of Direct Hydrogenation of MgB2 to Mg(BH4 )2 upon Mechanical Milling with THF, MgH2 , and/or Mg.

ChemPhysChem, 2019
Modification of magnesium diboride, MgB2 , by mechanical milling with THF, MgH2 , and/or Mg results in a lowering of the conditions required for its direct, bulk hydrogenation to magnesium borohydride, Mg(BH4 )2 , by 300 bar and 100 °C.

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Host Genus and Habitat Use Shape the Distribution of Batrachochytrium dendrobatidis Lineages in a Hyper‐Diverse Tropical Amphibian Community

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Anthropogenic change has facilitated the spread of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) in Brazil's Atlantic Forest, where two Bd lineages (Bd‐GPL and Bd‐Brazil) co‐occur. We successfully genotyped 252 Bd‐positive samples from a diverse amphibian assemblage spanning aquatic and terrestrial habitats and found that Bd lineage ...

Preparation and DC characteristics of MgB2/B/MgB2 Josephson junctions

Acta Physica Sinica, 2016
Since the discovery of its superconductivity, magnesium diboride (MgB2) has been identified as a promising superconductor to be used in Josephson junction devices due to its high transition temperature, large energy gap, long coherence length, and expected easier fabrication of Josephson junctions as compared with high temperature superconductors.
