Tunable Hydroxyapatite/Magnetite Nanohybrids with Preserved Magnetic Properties
( Wiley , 2022 , Article)Magnetic nanoparticles (MNPs) have been extensively investigated in a wide range of biomedical applications. Controlled coating of the MNPs is commonly utilized to protect and maintain their magnetic properties and to ... -
Tunable metal contacts at layered black-arsenic/metal interface forming during metal deposition for device fabrication
( Nature Research , 2022 , Article)Understanding the kinetics of interfacial reaction in the deposition of metal contacts on 2D materials is important for determining the level of contact tenability and the nature of the contact itself. Here, we find that ... -
Tundra Trait Team: A database of plant traits spanning the tundra biome
( Blackwell Publishing Ltd , 2018 , Article)Motivation: The Tundra Trait Team (TTT) database includes field-based measurements of key traits related to plant form and function at multiple sites across the tundra biome. This dataset can be used to address theoretical ... -
Tuning the activity of Cu-containing rare earth oxide catalysts for CO oxidation reaction: Cooling while heating paradigm in microwave-assisted synthesis
( Elsevier Ltd , 2018 , Article)(Ce-La-xCu)O2 catalysts with low (3 at.%) and high (10 at.%) Cu content were prepared by conventional microwave (MW) and enhanced microwave methods where air cooling (AC), while heating, was applied. The catalysts were ... -
