Special Issue in Coatings: Surface Treatment by Laser-Assisted Techniques II
Nanomaterials are one of the main topics of research at present. These materials, with at least one of their dimensions in the nanoscale (i.e., in a length range from 1 nm to 100 nm) have remarkable or unconventional properties compared to bulk materials. These materials are currently used in many applications; however, new potential uses are being investigated. In this sense, there is a large interest in their use in medicine, electronic devices, production and storage of energy, composite materials, etc. The production of nanomaterials is addressed through physical and/or chemical methods; however, most of these methods exhibit low reproducibility or a low production rate or make use of toxic chemicals. In order to avoid most of these drawbacks, laser-based synthesis of nanomaterials has emerged as an alternative to overcome these limitations. This family of methods uses a laser beam to produce different nanomaterials (e.g., nanoparticles, nanowires or 2D materials) using diverse approaches. Techniques such as those based on laser ablation, laser vaporization, pulsed laser deposition (PLD), laser–chemical vapor deposition (LCVD), etc. are being explored, at present, to fabricate these nanoscale materials with a controlled size and shape. In this context, the present Special Issue will include research papers addressing the most recent developments in this field to summarize the current state-of-the-art in the synthesis of nanomaterials using laser techniques.
Suitable topics include but are not limited to:
- Laser nanoprocessing;
- Laser ablation techniques, liquid-phase laser ablation;
- Laser-assisted chemical vapor deposition (LCVD);
- Pulsed laser deposition;
- Ultrafast laser synthesis of nanomaterials;
- Laser-Induced Fragmentation.

Abstract: The action of high-power pulsed laser radiation on materials in a supercritical carbon dioxide fluid (scCO2) allows one the formation of nanoparticles with a complex structure, impregnate of carries with developed surface by nanoparticles, and to impart the materials with new functional properties. The article presents a study of laser interaction with several specific materials in a scCO2 medium, aimed at the development of one-stage "green" synthesis of catalysts, hybrid and photoluminescent nanoparticles. Namely, the synthesis of catalysts consisting of palladium nanoparticles fixed on the surface or embedded into the volume of Al2O3 microparticles, bimetallic plasmonic nanoparticles consisting of gold and silver, and silicon nanoparticles photoluminescent in the red and near-infrared spectral regions, we are demonstrating. Mechanisms for the formation of such materials consistent with experimental data are proposed. The developed approaches and created functional nanomaterials can find application in solving various problems of nanophotonics, nanosensorics, catalysis and biomedicine.
Title: Dielectric and impedance properties of Zn-doped CCTO synthesized via rapid laser sintering of sol-gel derived precursors

Abstract: Zn-doped calcium copper titanate (CCTO) has been successfully synthesized by a rapid laser sintering of sol-gel derived precursors without conventional long-time heat treatment. The microstructure, dielectric properties, impedance spectroscopy have been detailedly investigated. The X-ray diffractometer results show that prepared Zn-doped CCTO is polycrystalline in a cubic structure with high purity. The scanning electron microscope and high resolution transmission electron microscope shows the Zn-doped CCTO has dense microstructure. Comparing with undoped CCTO, the dielectric permittivity increases and dielectric loss decreases, which reveals better dielectric properties. The impedance spectroscopy study shows the grain and grain boundary resistance decrease with rising temperature. The activation energies for the grain boundaries for Zn-doped CCTO were calculated using the slope of lnσ versus 1/T and were found to be 0.605 eV, smaller than undoped CCTO. This synthesizing route may be an efficient and convenient approach to settle excessive waste of resources.
