Atmospheric pressure plasma processing (APP) has received significant attention due to its combination of simplicity and a wide range of possibilities in surface treatments and modifications. Furthermore, atmospheric pressure plasma has a prominent technical significance due to its low-cost manufacturing and operations in contrast to a low-pressure plasma or even high-pressure plasma. This makes it an extremely versatile tool for any material processing and an emerging topic which will in future transform plasma processing and related industry.

Therefore, this symposium features the latest developments in APP design and applications. Furthermore, it was demonstrated that APPs could be successfully applied in materials science. For this reason, the papers related to atmospheric pressure plasma processing ranging from manufacturing to the deposition of coatings, surface modifications, and other treatments are considered.

Sustainable economic growth and high quality of life require an abundant supply of clean and affordable energy. Future energy sources include solar, wind, and nuclear energy—all of which can produce electricity as the primary form of energy. The conversion of this electrical energy to fuels (e.g., hydrocarbon or hydrogen) using common chemicals such as carbon dioxide and water though electrochemical processes (e.g., electrolysis reactions), provides an opportunity to remove the temporal variation in the energy supply from solar and wind energy. Electrolysis reactions may involve protons, hydroxide, oxide or other ions. This Electrosynthesis of Fuels 7 symposium provides an international forum for the presentation and discussion of the latest developments on electrolysis and related topics. The emphasis of this symposium is on recent advances relevant to the conversion and utilization of CO2 and/or H2O for synthesis of fuels and other chemicals. The application of the same cells as fuel cells is of special interest, because reversible cells that may be coupled with renewable or nuclear electric power production in order to increase efficiency through energy storage are of particular importance. Papers are solicited on the topics as follows:

(1) Electrolysis cells including electrolytes, electrodes, seals, and interconnects for the conversion of CO2 and H2O to fuels;

(2) Solid oxide fuel cells and protonic ceramic fuel cells;

(3) Electrocatalytic phenomena in oxygen electrodes and fuel electrodes;

(4) Electrosynthesis of ammonia;

(5) Electrochemical and chemical technologies for CO2 separation;

(6) Novel materials or concepts for CO2 conversion and capture.

The landscape of research and application of luminescent materials is changing rapidly, demanding novel functionalities and applications. These applications include bioimaging, solar cells, thermometry, sensors, plant biology, human-centric luminaires, and more. They need new materials with suitable physicochemical characteristics, including the appropriate and optimal luminescence properties required for such applications. Novel theoretical methods based on first principles methods, artificial intelligence, and machine learning are increasingly used in search of such materials. New processes to synthesize these materials and to integrate them into devices are being studied. Research also continues to identify new luminescent materials with improved performance for traditional lighting and display applications. The well-known yellow phosphor Y₃Al₅O₁₂:Ce³⁺ (YAG:Ce³⁺) continues to be the dominant phosphor for lighting LEDs due to its high efficiency and stability under various harsh conditions (temperature, flux, etc.). Phosphor research for blue-light-emitting diodes is currently focused on developing new narrow-band phosphors, especially for red emission. Such activities have led to a new class of (oxy-)nitride phosphors, and oxyhalide phosphors activated by tetravalent Mn. Perovskites are rapidly emerging as a new class of materials for lighting and solar cell applications.

This symposium is in honor of the late Prof. Blasse, who was highly recognized internationally and shaped the field of luminescent materials research. He combined groundbreaking fundamental discoveries with societal relevance, including discovering the phosphor that enabled white light LEDs. He had a deep and intuitive understanding of luminescence phenomena and often relied on clever chemical variations in host composition and structure to obtain insight into the underlying physics of luminescence and energy transfer phenomena of ions in solids.

Charge transfer is important to both the frontier of fundamental science and in the long term solutions for energy generation, conversion, and storage. Applications are diverse and include: hybrid inorganic-polymer composite photovoltaic solar cells, polymer electrolyte membrane fuel cells, and lithium ion and redox flow batteries, to name but a few. Although the charge carrier may be different in these devices there are common features in all charge transfer events or reactions. This symposium will provide a forum to present recent progress in understanding how local and larger aspects determines the nature and energetics of charge transfer and transport in various systems and devices. Current interest ranges from:

(A) Utilization of single or small groups of organic molecules or polymers as components in electronic devices;

(B) Exploitation of semiconductor and metal or metal oxide nanoparticles because of their high surface areas and other size-dependent properties;

(C) The effects of the density and distribution of fixed and/or mobile ions in electrodes and electrolytes.

Papers of interest include both experimental and theoretical studies that may be either applied or fundamental in focus.

Hexacyanoferrates and related cyanometallates exhibit model electron transfer properties that are of importance to both fundamental electrochemical science and technology and many electrochemical and related applications. In particular homo- and heteromatallic cyanide bridged networks and derived materials have proven to exhibit very rich and diverse electrochemical properties. Their redox properties can be tuned by stoichiometry and oxidation state of the constituent metal centers, incorporation of interstitial ions, or preparation methods. Polynuclear cyanometallates are promising open-framework systems for low-cost electrochemical energy storage applications. Both soluble and insoluble analogues of Prussian blue have been explored as cathode materials with lithium, sodium, potassium, magnesium, calcium, and even zinc intercalated ionic carriers. Electrochromic devices are another promising area for employing the unique properties of cyanometallates. Prussian blue itself exhibits electrocatalytic properties toward hydrogen peroxide and •OH radicals, and it has been used for biosensing and amperometric detection of glucose, L-cysteine, and glutamate. Mesoporous Prussian blue has been considered in cancer therapy due to its ability to absorb the 808-nm-laser-light and its subsequent transformation into heat. Furthermore, removal of radioactive cesium ions from contaminated water has been successfully achieved with Prussian blue and its metal substituted analogues.

This symposium aims at bringing together researchers in different areas of inorganic chemistry, materials chemistry, as well as electrochemistry with the ultimate goal of highlighting the current state of the art of mono- and polynuclear cyanometallates with the emphasis on recent developments and innovative examples related to energy conversion and storage, electrochromism, electrocatalytic processes, and biosensing. Contributions are sought but not limited to the papers investigating electrochemical properties leading to better understanding of the system’s physicochemical features and reaction mechanisms. Both experimental and theoretical papers as well as contributions involving simulations and DFT calculations are welcomed in an effort to forge a stronger link between the experiential parameters and resulting properties of the cyanometallate systems.
