Special Issue Information

Dear Colleagues,

Advanced nanoscale materials and (flexible) devices are cutting-edge areas of research and development in the field of materials science, nanotechnology, electronics, physics, chemistry, engineering, and more. These fields focus on creating novel materials and devices at the nanoscale level and incorporating flexibility and adaptability into their design. Researchers are continually exploring new ways to enhance the properties of nanomaterials and develop innovative manufacturing techniques to create functional and adaptable devices for a wide range of applications. These advancements have the potential to revolutionize industries such as electronics, healthcare, energy, and more.

This Special Issue will present comprehensive research outlining progress on advanced nanoscale materials and (flexible) devices. We invite authors to contribute original research articles and review articles covering topics which include, but are not limited to, the following:

  1. The synthesis of advanced materials;
  2. The preparation of (flexible) devices;
  3. Engineering of the nanophase;
  4. The application of advanced materials and (flexible) devices.

We look forward to receiving your contributions.

The cubic zirconia (ZrO2) is attractive for a broad range of applications. However, at room temperature, the cubic phase needs to be stabilized. The most studied stabilization method is the addition of the oxides of trivalent metals, such as Sc2O3. Another method is the stabilization of the cubic phase in nanostructures—nanopowders or nanocrystallites of pure zirconia. We studied the relationship between the size factor and the dopant concentration range for the formation and stabilization of the cubic phase in scandium-stabilized zirconia (ScSZ) films. The thin films of (ZrO2)1−x(Sc2O3)x, with x from 0 to 0.2, were deposited on room-temperature substrates by reactive direct current magnetron co-sputtering. The crystal structure of films with an average crystallite size of 85 Å was cubic at Sc2O3 content from 6.5 to 17.5 mol%, which is much broader than the range of 8–12 mol.% of the conventional deposition methods. The sputtering of ScSZ films on hot substrates resulted in a doubling of crystallite size and a decrease in the cubic phase range to 7.4–11 mol% of Sc2O3 content. This confirmed that the size of crystallites is one of the determining factors for expanding the concentration range for forming and stabilizing the cubic phase of ScSZ films. Full article

The AlxCoCrFeNi2.1 (x = 0, 0.3, 0.7, 1.0, 1.3) multi-component high-entropy alloy (HEA) was synthesized by mechanical alloying (MA) and Spark Plasma Sintering (SPS), The impact of the percentage of Al on crystal structure transition, microstructure evolution and mechanical properties were studied. Crystal structure was investigated by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The results show that with the increasing of Al content, the crystal structure of the alloys gradually transformed from a nanocrystalline phase of FCC to a mix of FCC and BCC nanocrystalline. The hardness was found to increase steadily from 433 HV to 565 HV due to the increase in fraction of BCC nanocrystalline phase. Thus, the compressive fracture strength increased from 1702 MPa to 2333 MPa; in contrast, the fracture strain decreased from 39.8% to 15.6%. Full article
