Special Issue Information

Dear Colleagues,

It is my pleasure to announce the launch of a new Special Issue of the journal Nanomaterials entitled “Femtosecond Laser Fabrication of Micro/Nanostructures and Applications (Second Edition)”. As Guest Editor, I cordially invite you to submit a manuscript for consideration and possible publication in this Special Issue.

During the last two decades, femtosecond laser fabrication techniques have shown versatility in processing a variety of one-, two- and three-dimensional micro- and nanostructures with a broad spectrum of materials, due to the unique features of ultrahigh peak power and ultrashort duration of femtosecond laser pulses. This Special Issue is devoted to recent advances in femtosecond laser fabrication of micro/nanostructured particles, surfaces and devices using various soft and hard materials. The topics include all relevant aspects of micro- and nanostructures fabricated by femtosecond laser-based techniques, such as femtosecond laser direct writing, laser ablation, laser pattering, laser deposition, etc., and their applications in areas such as optics and photonics, spectroscopy, electronics, and biomimetics.

This Special Issue welcomes original and review contributions.

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 250 words) can be sent to the Editorial Office for assessment.

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 2400 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.

Functional steel surfaces engineered through tailored micro-nano structures are increasingly vital for various applications such as high-performance aerospace components, energy conversion systems and defense equipment. Femtosecond laser filament processing is a recently proposed remote fabrication technique, showing the capability of fabricating micro-nano structures on irregular and large-area surfaces without the need of tight focusing. Nevertheless, the mechanisms underlying the formation of filament-induced structures remain not fully understood. Here we systematically investigate the formation mechanisms of filament-induced micro-nano structures on stainless steel surfaces by processing stainless steel in three manners: point, line, and area. We clarify the decisive role of the unique core–reservoir energy distribution of the filament in the formation of filament-induced micro-nano structures, and reveal that ablation, molten metal flow, and metal vapor condensation jointly drive the structure evolution through a dynamic interplay of competition and coupling, giving rise to the sequential morphological transitions of surface structures, from laser-induced periodic surface structures to ripple-like, crater-like, honeycomb-like, and ultimately taro-leaf-like structures. Our work not only clarifies the mechanisms of femtosecond laser filament processed morphological structures on steels but also provides insights onto intelligent manufacturing and design of advanced functional steel materials.
