    Abstract
    Bimetallic nanoparticles are often superior candidates for a wide range of technological and biomedical applications owing to their enhanced catalytic, optical, and magnetic properties, which are often better than their monometallic counterparts. Most of their properties strongly depend on their chemical composition, crystallographic structure, and phase distribution. However, little is known of how their crystal structure, on the nanoscale, transforms over time at elevated temperatures, even though this knowledge is highly relevant in case nanoparticles are used in, e.g...

  • Adaptive iron-based magnetic nanomaterials of high performance for biomedical applications

    15 days ago - By Springer

    Abstract
    With unique physicochemical properties and biological effects, magnetic nanomaterials play a crucial role in the biomedical field. In particular, magnetic iron oxide nanoparticles are approved by the United States Food and Drug Administration for clinical applications at present due to their low toxicity, biocompatibility, and biodegradability. Despite the unarguable effectiveness, massive space for improving such materials' performance still needs to be filled. Recently, many efforts have been devoted to improving the preparation methods based on the materials' biosafety...
