Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to this Special Issue on “Thin Films and Nanostructures Deposition Techniques”. Thin films and nanostructures have become the building blocks of technological devices, experiencing highly accelerated growth in recent decades. This has been enabled by the continuous development of new interesting material properties, especially in the form of thin films or nanostructures. Researchers and engineers in fields such as chemistry, physics, nanotechnology, or materials science are constantly trying to improve, find, or modify deposition techniques to  design and develop technological devices meeting industrial demands.

This Special Issue is open to everyone working in research fields related to the synthesis and deposition of nanostructures and thin films. Surface modification techniques such as laser nanostructuring, ion implantation, surface oxidation/nitridation, etc., are also welcome.

This Special Issue will  be focused on (but not limited to) the following topics:

  • Pulsed laser deposition (PLD);
  • Laser ablation in liquids;
  • Sol–Gel;
  • Chemical bath deposition (CBD);
  • Sputtering;
  • Thermal evaporation;
  • Closed-space vapour transport (CSVT);
  • Chemical vapour deposition (CVD);
  • Molecular beam epitaxy (MBE);
  • Spray pyrolysis;
  • Precipitation;
  • Atomic layer deposition (ALD);
  • Solvothermal synthesis.

The majority of the polymeric materials used in the industry are derived from petroleum and decompose slowly, resulting in waste that poses environmental issues. As a result, there has been a concerted effort to find alternative materials that cover their engineering performance. Biopolymers have emerged as leading contenders because they can mimic the properties of synthetic polymers while being derived from natural and renewable sources. Several projects are focused on developing biomaterials for these applications. This study presents a modification of the mechanical properties of a gelatin-based material with the crosslinking agent sodium tripolyphosphate (NaTPP) by reinforcement with agar. The gelatin–agar (G-Ax) samples exhibited a homogeneous color and flexibility, sharing similar crystalline structures and functional groups. However, the transversal section of the gelatin-only film was modified by the addition of agar, from a porous morphology to a lamellar morphology at nanometric scale thickness. Notably, the agar samples demonstrated greater stress resistance, yield stress, and strain than the gelatin-only sample. These findings highlight the potential of biopolymers such as gelatin and agar as viable alternatives to conventional materials, contributing to the research on eco-friendly solutions for different engineering applications.

The dynamic response in propane atmospheres at different voltages was investigated for samples made from powders of the semiconductor oxide CoSb2O6 synthesized using the microwave-assisted colloidal method. Powders of the compound calcined at 700 °C were studied with X-ray diffraction, confirming the CoSb2O6 crystalline phase. The microstructural characteristics of the oxide were analyzed using scanning and transmission electron microscopy (SEM/TEM), revealing a high abundance of nanorods, nanoplates, and irregular nanoparticles. These nanoparticles have an average size of ~21 nm. Using UV-Vis, absorption bands associated with the electronic transitions of the CoSb2O6’s characteristic bonds were identified, which yielded a bandgap value of ~1.8 eV. Raman spectroscopy identified vibrational bands corresponding to the oxide’s Sb–O and Co–O bonds. Dynamic sensing tests at 300 °C confirmed the material’s p-type semiconductor behavior, showing an increase in resistance upon exposure to propane. Critically, these tests revealed that the sensor’s baseline resistance and overall response are tunable by the applied voltage (1–12 V), with the highest sensitivity observed at the lowest voltages. This establishes a clear relationship between the electrical operating parameters and the sensing performance. The samples exhibited good operational stability, capacity, and efficiency, along with short response and recovery times. Extra-dry air (1500 cm3/min) was used as the carrier gas to stabilize the films’ surfaces during propane detection. These findings lead us to conclude that the CoSb2O6 could serve as an excellent gas detector. Full article

Ablative materials are widely employed to protect space vehicles from the extreme thermal conditions experienced during their flight into a planetary atmosphere. Carbon-phenolic ablators are composed of a phenolic matrix and a fibrous carbon reinforcement. In the present study, the fibrous reinforcement has been modified through the deposition of thin protective layers of zirconium oxide and aluminum oxide, with the objective of reducing fiber recession and oxidation. The depositions were carried out via atomic layer deposition (ALD), a method that allows for the controlled deposition of uniform and conformal coatings on the carbon felt fibers. The depositions were subsequently evaluated through SEM-EDS analysis. Pristine and ALD-modified felts were impregnated with a phenolic resin matrix and the ablation performance of the composite materials was evaluated through oxyacetylene flame tests. The results demonstrated that, in comparison to uncoated ablators, the ALD-modified samples exhibited enhanced performance in terms of mass loss and surface recession: compared to uncoated ablators, the former was 14% lower and the latter was diminished by 50%. Moreover, the morphological characterization of the tested specimens revealed a significantly reduced degree of oxidation of the coated fibers which were directly exposed to the flame. Full article
