Special Issue Information

Dear Colleagues,

Nanostructured materials are of particular interest in the materials community due to their unique microstructures and properties. The microstructural length scale of nanostructured materials is often on the order of a few to tens of nanometers. The nanoscale crystallites in the materials are separated by abundant interfaces, such as grain boundary, phase interfaces, free surfaces, etc., often resulting in a deviation from the thermodynamic equilibrium state. Due to the highly non-equilibrial state, the properties of most nanostructured materials may deviate from those of the coarse-grained counterparts with the same chemical composition.

This Special Issue aims to present the latest advances in both experiments and simulations that can improve our understanding of the fundamentals and applications of nanostructured metallic materials. Both original research articles and reviews are welcome. This Special Issue will cover a wide range of topics, including but are not limited to the following:

  • Advanced manufacturing of bulk nanostructured metals;
  • Mechanical properties and deformation mechanisms of nanocrystalline metallic materials;
  • Advanced characterization techniques of nanostructured materials, such as in situ characterization, synchrotron X-ray, neutron diffraction, etc;
  • Radiation effects on nanostructured metals;
  • Thermal, electrical, magnetic, and optical properties of nanocrystalline metallic materials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Gold nanoparticles are widely used as local heaters under optical excitation. Hybrid molecular-plasmon nanostructures based on gold nanoparticles and water-soluble porphyrin have been developed. A colloidal solution of gold nanoparticles was obtained by laser ablation of metallic gold in water, ensuring its highest chemical purity. The hybrid nanostructures formation was performed due to the Coulomb interaction of cationic porphyrin and gold nanoparticles. The revealed functional properties of hybrid nanostructures make them promising for controllable nano-heater applications (for example, photothermal therapy). Gold nanoparticles act as heaters, whereas porphyrin serves as a fluorescent thermometer with a single optical excitation. Full article
