Dear Colleagues,

One-dimensional nanostructures, such as wires, tubes, belts, and rods, have been extensively studied for the past two decades due to their interesting and unique electronic, optical, thermal, mechanical, and magnetic properties. In the past decade, a tremendous amount of progress has been made in the field of one-dimensional nanostructures. However, there is still a significant need for the exploration and an improved understanding of the processes that occur during the growth of nanowires, improving our ability to assemble nanostructures into specific orientations with complex 3D geometries, as well as the engineering of the interfaces that control the transfer of energy, force, charge, and or mass across them. It is also important that these types of architectures be fabricated at a large scale, with high-throughput, and at low cost, while simultaneously maintaining the material properties at the nanoscale. An emphasis also needs to be placed on the use of low-cost, environmentally-friendly, and resource-abundant materials, while minimizing waste caused by the use of more expensive materials for processing.

This Special Issue of Nanomaterials will address the following key topics:

1. Different types of nanowire synthesis techniques (chemical and physical methods), as well as unconventional or new emerging techniques;
2. synthesis of NWs on new types of conventional and unconventional substrates;
3. synthesis of complex nanowires with controlled crystalline morphologies, orientations, and surface architectures;
4. selective or templated growth of NWs using new methods of patterning of the substrate;
5. efficiency of the chemical synthesis method and the factors limiting the growth process;
6. scaling behavior or strategies for large-scale growth of nanowires;
7. controlling nanowire growth, i.e., controlling the morphology, orientation, dispersion, polarity, and intrinsic properties, and tuning the electrical and optical properties by doping;
8. integration of the nanowires into new heterostructures combining different types of compound semiconductors;
9. the impact of these nanomaterials on the environment;
10. new properties of the synthesized nanowires; and
11. applications of these nanowires for lighting, energy harvesting and storage, sensing, and biological purposes.

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. Nanomaterials is an international peer-reviewed open access semimonthly 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 2900 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.
