Special Issue Information

Dear Colleagues,

To date, laser-derived technology, including laser melting, laser fragmentation, laser ablation, pulse laser deposition, etc. has been deemed as one outstanding and unique strategy for fabricating functional nanostructures and preparing advanced nanomaterials. By comparison of general chemical methods, advanced nanomaterials fabrication and ablation by lasers presents unique advantages, including, rapid process, controllability, without many chemical reagents, large-scale, limitless in material or medium. Many international groups made a lot of contributions in understanding the generation mechanism of nanomaterials/nanostructures, modeling of growth processes, up-scaling preparation, and implementation in the semiconductor manufacturing process, renewable energy, bionics, and biomedical applications.

Despite such progress and accumulation, advanced nanomaterials with more precise controllability and superior properties remain to be produced by laser fabrication and ablation. With this aim, potential topics include, but are not limited to, the following:

  • pulse laser deposition in vacuum or gas atmosphere
  • laser fabrication (ablation, fragmentation, melting) in liquids
  • laser processing of metals, carbon materials, polymers, ceramics, etc.
  • interaction process of lasers and matters (solid/liquid/gas)
  • applications in energy storage and conversion, catalysis, biomedical, bioics, etc.
  • generation mechanism of nanomaterials or nanostructures

We welcome papers sharing your research and advances in this field for publication in this Special Issue of Nanomaterials.

Laser fabrication of metallic superhydrophobic surfaces (SHSs) for anti-frosting has recently attracted considerable attention. Effective anti-frosting SHSs require the efficient removal of condensed microdroplets through self-propelled droplet jumping, which is strongly influenced by the surface morphology. However, detailed analyses of the condensate self-removal capability of laser-structured surfaces are limited, and guidelines for laser processing parameter control for fabricating rationally structured SHSs for anti-frosting have not yet been established. Herein, a series of nanostructured copper-zinc alloy SHSs are facilely constructed through ultrafast laser processing. The surface morphology can be properly tuned by adjusting the laser processing parameters. The relationship between the surface morphologies and condensate self-removal capability is investigated, and a guideline for laser processing parameterization for fabricating optimal anti-frosting SHSs is established. After 120 min of the frosting test, the optimized surface exhibits less than 70% frost coverage because the remarkably enhanced condensate self-removal capability reduces the water accumulation amount and frost propagation speed (<1 μm/s). Additionally, the material adaptability of the proposed technique is validated by extending this methodology to other metals and metal alloys. This study provides valuable and instructive insights into the design and optimization of metallic anti-frosting SHSs by ultrafast laser processing. Full article

Nanogratings (NGs) are self-assembled subwavelength and birefringent nanostructures created by femtosecond laser direct writing (FLDW) in glass, which are of high interest for photonics, sensing, five-dimensional (5D) optical data storage, or microfluidics applications. In this work, NG formation windows were investigated in nine commercial glasses and as a function of glass viscosity and chemical composition. The NG windows were studied in an energy—frequency laser parameter landscape and characterized by polarizing optical microscopy and scanning electron microscopy (SEM). Pure silica glass (Suprasil) exhibits the largest NG window, whereas alkali borosilicate glasses (7059 and BK7) present the smallest one. Moreover, the NG formation windows progressively reduced in the following order: ULE, GeO2, B33, AF32, and Eagle XG. The NG formation window in glasses was found to decrease with the increase of alkali and alkaline earth content and was correlated to the temperature dependence of the viscosity in these glasses. This work provides guidelines to the formation of NGs in commercial oxide glasses by FLDW. Full article
