Special Issue Information

Dear Colleagues,

The use of lasers for the synthesis of nanomaterials continues to represent an important area of academic and applied research. There are numerous approaches by which nanomaterials can be synthesized by laser techniques. These include, for example, laser ablation of solids in different environments, gases, and liquids and laser fragmentation of micro-powders. We invite authors to contribute to this Special Issue with original research articles and comprehensive review articles covering the most recent progress and new developments in the field of laser synthesis of nanomaterials. This Special Issue aims to cover a broad range of subjects, from fundamental mechanisms and modeling of nanomaterial synthesis to the design and characterization of novel schemes of laser installations for the synthesis of nanoparticles and nanostructures. Potential topics include, but are not limited to:

  1. laser synthesis of nanocomposites;
  2. green laser synthesis of nanoparticles in liquids;
  3. laser design and the preparation of novel nanotextured/nanostructured surfaces for SERS and other applications;
  4. fundamental aspects of the laser synthesis of nanomaterials;
  5. laser synthesis of nanoparticles for medical and biological applications; and
  6. industrial-scale laser synthesis of nanoparticles.

In this paper we present the laser nanowelding process of silver nanowires (AgNWs) deposited on flexible polymer substrates by continuous wave (CW) lasers. CW lasers are cost-effective and can provide moderate power density, somewhere between nanosecond pulsed lasers and flash lamps, which is just enough to perform the nanowelding process efficiently and does not damage the nanowires on the polymer substrates. Here, an Nd:YAG CW laser (wavelength 532 nm) was used to perform the nanowelding of AgNWs on polyethylene terephthalate (PET) substrates. Key process parameters such as laser power, scan speed, and number of scans were studied and optimized, and mechanisms of observed phenomena are discussed. Our best result demonstrates a sheet resistance of 12 ohm/squ with a transmittance at λ = 550 nm of 92% for AgNW films on PET substrates. A transparent resistive heater was made, and IR pictures were taken to show the high uniformity of the CW laser nanowelded AgNW film. Our findings show that highly effective and efficient nanowelding can be achieved without the need of expensive pulse lasers or light sources, which may contribute to lower the cost of mass producing AgNWs on flexible substrates.

The additive manufacturing of low elastic modulus alloys that have a certain level of porosity for biomedical needs is a growing area of research. Here, we show the results of manufacturing of porous and dense samples by a laser powder bed fusion (LPBF) of Ti-Nb alloy, using two distinctive fusion strategies. The nanostructured Ti-Nb alloy powders were produced by mechanical alloying and have a nanostructured state with nanosized grains up to 90 nm. The manufactured porous samples have pronounced open porosity and advanced roughness, contrary to dense samples with a relatively smooth surface profile. The structure of both types of samples after LPBF is formed by uniaxial grains having micro- and nanosized features. The inner structure of the porous samples is comprised of an open interconnected system of pores. The volume fraction of isolated porosity is 2 vol. % and the total porosity is 20 vol. %. Cell viability was assessed in vitro for 3 and 7 days using the MG63 cell line. With longer culture periods, cells showed an increased cell density over the entire surface of a porous Ti-Nb sample. Both types of samples are not cytotoxic and could be used for further in vivo studies. Full article
