Functional thin films were applied at many electronic devices and they included various research fields such as ferroelectric, transparent conductive oxide, and magnetic materials etc. Functional thin films were prepared using chemical vapor deposition, sputtering, pulsed laser deposition, and spin-coating. They were characterized through the typical characterization techniques such as XRD, SEM, AFM, TEM, AES, XPS, and SIMS. Recently, oxide thin films also were applied at dye-sensitized solar cells. Therefore, Oxide thin film sessions include various fields such as processing, characterization, and applications.

Hydrogen production via solar energy has been widely studied as an environmentally-friendly and sustainable source of energy. Considering the thermodynamic potential, a single-component semiconductor that possesses a higher band gap than 1.23 V can simultaneously generate hydrogen and oxygen gas from water. However, overall water splitting through a single-component conventional semiconductor is usually limited by low activity to visible light and high kinetic overpotentials. A critical requirement for outstanding light absorption material and catalysts is, not only its ability to boost the kinetics of a chemical reaction, but also provide the necessary durability against electrochemical and photo-induced degradation. Generally, precious metals, such as platinum, exhibit superior performance under these requirements; however, the high cost of precious metals are another challenging barrier for their widespread commercial use. To address this critical and long-standing technical barrier, intense research efforts for developing an efficient, durable, and inexpensive alternative photoactive and catalytic nanomaterials have been recommended, which comprises low-dimensional transition metal oxides and carbides, transitional metal dichalcogenides, carbon-based nanomaterials, and earth-abundant nanomaterials. The symposium aims to cover recent advances in the development of various kinds of materials related to photocatalysts, photoelectrodes, and co-catalysts intended for solar-driven water splitting.

Functional ceramics with intrinsically new and tailored properties are key elements for developing sustainable solutions for energy technologies. Specifically, this symposium will focus on new energy technologies and devices based on inorganic, hybrid and composite materials. Processing of multifunctional ceramics and techniques that offer advanced processing, improved properties, and low-cost/low-temperature synthesis will form a strong focus. Applications related to energy applications such as perovskite materials, batteries, fuel cells, water splitting, and carbon dioxide conversion as well as transparent conductors will be addressed. Challenges in functional ceramics related to the large scale production and integration of functional and structural materials are highly desired. This event will provide an international forum for the presentation of technological advances, and latest research on the state-of-the-art in innovative processing and device applications of functional ceramics to meet the challenges of sustainable energy and environment technologies.
