Special Issue Information

Dear Colleagues,

The journal Coatings is currently running a Special Issue entitled "Energy Efficient Coatings” that will explore different aspects of energy-efficient coatings. Energy-efficient coatings find applications in different environments, such as automotive, buildings, photovoltaic, agrivoltaic, aerospace, thermodynamic, etc. For example, in the building industry, such coatings can lower internal building temperatures, preventing the heat island effect and driving down the energy cost for cooling systems, while in the automotive industry, they can be used to meet stringent environment protection regulations pertaining to emission control and fuel efficiency. The aim of this Special Issue is to publish original research articles, critical reviews from leading researchers on all aspects related to coating design, deposition technology, and the required functional properties of energy-efficient coating and substrate material. As Guest Editor of this Special Issue, I am writing to inquire whether you would consider contributing an article or review paper focusing but not limited to the following topics of interest on energy-efficient coatings

  • Optical filters for energy efficiency;
  • Coatings for passive cooling by selective infrared emission;
  • Energy-efficient coatings for building applications;
  • Energy-efficient automotive coatings;
  • Spectrally selective energy coating for agrivoltaic applications.

 Thank you for your kind attention.

Dr. Manuela Ferrara

An integrated solar heating system with a new type of phase change material (PCM), solar collectors and test building were developed. The exothermal and endothermal behaviors of the PCM were determined, and the stability and comfort of the solar heating system were researched. The integrated solar heating system was operated on the test building heating for one heating period, and the temperature of heating rooms, the outdoors, and the contrast rooms were recorded and collected by a data acquisition system. The collected temperature data indicated that the integrated solar heating system with PCM could produce heating stability and continuity; the average temperature of the heating rooms using PCM was 4.6 °C higher than the contrast rooms, which did not use PCM. Taking 16 °C as the lowest standard room temperature, the integrated solar heating system could save approximately 45% of energy during one heating period. The successful development of an integrated solar heating system, coupled with phase change materials and solar collectors for building heating will lay a solid foundation for achieving the goals of building energy conservation and “carbon peaking and carbon neutrality”.

This study aimed to investigate if a thermal barrier coating (TBC) affected the energy efficiency of 3D printers. In accordance with this purpose, the used TBC technique is clearly explained and adapted to a nozzle in a simulation environment. Brass, copper, and hardened steel were selected to be the materials for the nozzles. The reason for the usage of a thermal barrier coating method is that the materials are made with low thermal conductivity, which reduces the thermal conductivity and energy losses. Yttria-stabilized zirconia was used to coat material on brass, copper, and hardened steel. To prevent temperature fluctuations, yttria-stabilized zirconia together with a NiCRAl bond layer was used and, thus, heat loss was prevented. Additionally, the paper addressed the effects of the coating on the average heat flux density and the average temperature of the nozzles. In addition, by means of the finite element method, steady-state thermal analyses of the coated and uncoated nozzles were compared, and the results show that the thermal barrier coating method dramatically reduced energy loss through the nozzle. It was found that the average heat flux was reduced by 89.4223% in the brass nozzle, 91.6678% in the copper nozzle, and 79.1361% in the hardened steel nozzle. Full article

Over the past few years, thermoelectrics have gained interest with regard to thermoelectricity interconversion. The improvement in the efficiency of the thermoelectric material at an ambient temperature is the main problem of research. In this work, silicon–germanium (SiGe) thin films, owing to superior properties such as nontoxicity, high stability, and their integrability with silicon technologies, were studied for thermoelectric applications. P-type SiGe thin films were deposited on quartz substrates by DC/RF magnetron sputtering and annealed at three different temperatures for 1 hour. Significant enhancement in the Seebeck coefficient was achieved for the sample annealed at 670 °C. A high power factor of 4.1 μWcm−1K−2 was obtained at room temperature. Full article
