Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your work to our Special Issue entitled "New Functional Coatings and Thin Films for Sensor and Green Energy Technologies”. The new challenges that we face in modern life, such as the expanding need to monitor health, the food quality and environmental control, along with the strategic areas related to clean energy, require the development of a wide range of products and technological applications, such as sensors, photoelectronic devices, low-cost and fast electronics, energy conversion, harvesting, and storage. Advances in functional materials, particularly in the area of nanotechnology, have sparked significant research progress in the fabrication of high-quality coatings used in a wide range of technological applications. The material composition, structure, and dimensionality have decisive impacts on their properties. Additionally, the ability to dope or to introduce side chemical groups can significantly alter material sensing properties, functionality, and high performance. The design of nanostructured organic, inorganic, and composite materials, if specially controlled by the aid of various techniques, can also lead to a reduction in fabrication cost for sensing and photovoltaic devices, as well as their practical application.

This Special Issue aims to gather and highlight recent research achievements in the design and use of functional materials for active coatings in a range of sensing applications, from photoelectronic to chemical and bio-sensing devices.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Synthesis, engineering, and characterization of new functional materials/coatings/thin films with maximized performance;
  • Meso, micro, and nanoscale processing;
  • Theoretical calculation of advanced materials for coatings;
  • Adsorption phenomena, coatings for sensing, and protective coatings;
  • New functional materials/coatings/thin films for solar energy conversion and storage.

We look forward to receiving your contributions.

In recent years, the remarkable energy density of high-nickel ternary materials has captured considerable attention. Nevertheless, the high-nickel ternary cathode material encounters several challenges, including cationic mixing, microcrack formation, poor cycling capability, and limited thermal stability. Coating, as a viable approach, proves to be effective in enhancing the material properties. In this study, the LiNi0.8Co0.1Mn0.1O2 (NCM811) sample underwent a dry grinding process, followed by Y2O3 coating and subsequent sintering at varying temperatures. The microstructure, morphology, and electrochemical properties of the materials were meticulously examined, and the underlying mechanism of coating modification was meticulously explored. The outcomes demonstrate the attainment of dual coating and doping effects through Y2O3 modification. Y2O3 coating mitigates the direct interaction between the NCM811 surface and the electrolyte, thereby inhibiting undesired side reactions at the interface. Moreover, the Y element infiltrates the crystal structure, imparting stability at elevated sintering temperatures. Remarkably, the Y2O3-coated cathode materials exhibit significantly enhanced cycling stability, discharge capacity, and rate performance. These findings can provide novel insights that can be harnessed to improve the energy density cathode material of NCM811. Full article

Cobalt nickel oxide films are deposited on Si(111) or fluorine-doped tin-oxide-coated (FTO) glass substrates employing a pulsed hollow-cathode discharge. The hollow cathode is operated with argon gas flowing through the nozzle and with O2 gas admitted to the vacuum chamber. Three different cathode compositions (Co20Ni80, Co50Ni50, and Co80Ni20) are investigated. Deposited and annealed thin films are characterized by X-ray diffraction, infrared (Raman) spectroscopy, and ellipsometry. As-deposited films consist of a single mixed cobalt nickel oxide phase. Upon annealing at 600 °C, the mixed cobalt nickel oxide phase separates into two cystalline sub-phases which consist of cubic NiO and cubic Co3O4. Annealed films are investigated by spectroscopic ellipsometry and the optical bandgaps are determined. Full article
