“…Sol-gel synthesis is an increasingly popular wet chemical synthesis method, first adopted for the synthesis of glass materials and novel compositions of ceramic oxides in the 1960s [435]. However, numerous properties need to be controlled to reach superior properties for produced ceramics when compared to solid-state processing [433,436,437]. The synthesis process includes the transition of monomers from a solution or colloidal liquid system (sol) into an integrated solid network (gel) [438].…”

Solid oxide fuel cells (SOFCs) are amongst the most widely used renewable alternative energy systems with near-zero carbon emission, high efficiency, and environment-friendly features. However, the high operating temperature of SOFCs is still considered a major challenge due to several issues regarding the materials’ corrosion, unwanted reactions between layers, etc. Thus, low-temperature SOFCs (LT-SOFCs) have gained significant interest during the past decades. Despite the numerous advantages of LT-SOFCs, material selection for each layer is of great importance as the common materials have not shown a desirable performance so far. In addition to the selection of the materials, fabrication techniques have a great influence on the properties of the SOFCs. As SOFCs with thinner layers showed lower polarisation resistance, especially in the electrolyte layer, different thin-film fabrication methods have been employed, and their effect on the overall performance of SOFCs has been evaluated. In this review, we aim to discuss the past and recent progress on the materials and thin-film fabrication techniques used in LT-SOFCs.

“…A variety of optoelectronic devices, including diodes, solar cells, and panel displays, among others, increasingly depend on transparent conductive materials (TCMs) as functional components [1][2][3]. ITO, an indium-doped oxide, has garnered significant attention as one of the transparent conducting oxides in recent times.…”

“…The influence of magnesium addition on the mechanical, physical, thermal, chemical, and microstructural characteristics of the cores was examined by fabricating MgO-containing alumina-based ceramic cores using MgTi 2 O 5 [2]. Metal oxide-loaded alumina nanoparticles that included 12.5 % ZnO and 12.5 % MgO significantly increased the effectiveness of oxidative desulfurization.…”

Transparent conducting oxides (TCO) offer the uncommon functional combination of being both transparent and electrically conductive. For this reason, this study is concerned with the preparation of the triple heterojunction consisting of magnesium oxide, alumina, and ITO using a pulsed laser deposition method with a laser intensity of 3 J. Alumina bulk pellets in propanol were irradiated (Nd:YAG) at a wavelength of 1064 nm. Laser ablation was performed at a laser intensity of 3 J and deposited on ITO, which was then left to dry for 24 hours. The same method was used to attain magnesium nanoparticles, which were spin-coated on the previous sample and dried in a 500 °C oven for 4 hours. Then the properties of nanoparticles were investigated using X-ray diffraction, UV spectroscopy, and scanning electron microscopy (SEM). The results were obtained by UV and XRD analyses. From SEM images, the average size of the synthesized nanoparticles was determined to be about 25–35 nm. Aluminum oxide, MgO, and ITO are 1-D nanostructured semiconductors that function as transparent conducting oxide thin film while also increasing absorption in the visible spectrum. ITO is identified as an appropriate electrode material for infrared photoelectric devices.
