Special Issue Information

Dear Colleagues,

The improvement of fabrication resolutions is an eternal challenge for miniaturizing and enhancing the integration degrees of devices. Laser processing is one of the most widely-used techniques in manufacturing due to its high-flexibility, high-speed, and environment-friendliness. The fabrication resolution of laser processing is, however, limited by the diffraction limit. Recently, many efforts have been made to overcome the diffraction limit in nano fabrication. Specifically, combinations of multiphoton absorption by ultrafast lasers and the threshold effect associated with a Gaussian beam profile provide fabrication resolutions far beyond the diffraction limit. The use of the optical near-field achieves nano ablation with feature sizes below 100 nm. Multiple pulse irradiation from the ultrafast laser produces periodic nanostructures with a spatial period much smaller than the wavelength. Unlimited diffraction resolutions can also be achieved with shaped laser beams. In the meanwhile, lasers are also widely used for synthesis of nano materials including fullerenes and nano particles. In view of the rapid advancement of this field in recent years, this Special Issue aims at introducing the state-of-the-art in nano fabrication and nano lithography, based on laser technologies, by leading groups in the field.

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 papers will be 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 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 1500 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.

Tentative title: Synthesis of Iron Silicide Nanomaterials by Femtosecond Laser Ablation and Processing in Liquids
Short abstract: The technique of laser synthesis and processing of colloids has attracted increasing attention due to its simplicity and the gentle working environment. However, the current works mainly focus on synthesis of metal, oxide and hydroxide nanomaterials. There are seldom reports about the synthesis of silicide nanomaterials, such as FeSi and FeSi2 which are good photocatalysts for hydrogen evolution. This works tend to investigate the possibility of synthesizing iron silicide by both laser ablation and laser processing in liquids. Since iron is easy to be oxidized into oxide during laser ablation and processing, solutions (e.g., water, ethanol and acetone) and laser properties (e.g., laser power) are varied to check their effects on the phase purity of the synthesized iron silicide nanomaterials. The underlying reasons for the phase variation are discussed. Finally, the magnetic properties of the synthesized silicide particles are presented.

Tentative title: Wide applicability of nanomaterial-participating two-photon polymerization for 3D printing of complex structures
Short abstract: This work demonstrates the wide applicability of nanomaterial-participating (e.g., Au, Ag, TiO2, etc.) two-photon polymerization for 3D printing of complex structures. The particle concentration and synthesis condition are optimized for different nanomaterials. Aiming at escalating the process for high-speed prototyping, the scanning speed, object lens and laser energy are also systematically investigated. This work tends to give an overview of the effects of different nanomaterials on the printed 3D structures and depict the “process window” for 3D printing using different nanomaterials.
