MXenes are a 2D materials (2DM) class with high industrialization potential, owing to their superb properties and compositional variety. However, ensuring high etching efficiency in the synthesis process without involving toxic, hazardous or non‐sustainable chemicals are challenging. In this work, an upscalable electrochemical MXene synthesis is pr...
Chemical recycling of polymer waste is a promising strategy to reduce the dependency of chemical industry on fossil resources and reduce the increasing quantities of plastic waste. A common challenge in chemical recycling processes is the costly downstream separation of reaction products. For polybutylene succinate (PBS) no effective recycling conc...
When two insulating, neutral materials are contacted and separated, they exchange electrical charge¹. Experiments have long suggested that this ‘contact electrification’ is transitive, with different materials ordering into ‘triboelectric series’ based on the sign of charge acquired². At the same time, the effect is plagued by unpredictability, pre...
Multi-element alloys and high-entropy alloys show promising electrocatalytic behavior for water splitting and other catalytic reactions, due to their highly tunable composition. While preparation and synthesis of these materials are thoroughly investigated, the true reactive surface composition is still not well understood, as it may significantly...
Carbon‐based electrodes are used in flow batteries to provide active centers for vanadium redox reactions. However, strong controversy exists about the exact origin of these centers. This study systematically explores the influence of structural and functional groups on the vanadium redox reactions at carbon surfaces. Pyridine, phenol and butyl con...
The degradation and aging of carbon felt electrodes is a main reason for the performance loss of Vanadium Redox Flow Batteries over extended operation time.
The aeronautical industry demands facile lightweight and low-cost solutions to address climate crisis challenges. Graphene can be a valid candidate to tackle these functionalities, although its upscalability remains difficult to achieve. Consequently, graphene-related materials (GRM) are gathering massive attention as top-down graphite exfoliation...
An airplane is statistically struck by lightning every year. The need for lightweight aircraft to reduce the production of carbon dioxide has significantly reduced the presence of metals in favour of composites, resulting in lower lightning strike protection efficiency. In this perspective, we critically review the state of technologies in lightnin...
To reduce the global emissions of CO2, the aviation industry largely relies on new light weight materials, which require multifunctional coatings. Graphene and its derivatives are particularly promising for combining light weight applications with functional coatings. Although they have proven to have outstanding properties, graphene and its precur...
Lower WC grain sizes in the nanometer range have positive effects on the properties of hardmetals (e.g., hardness), but the established production processes of WC are limited to grain sizes of about 150 nm. To produce WC powder with grain sizes in the lower nanometer range, an alternative WC production process based on the chemical vapor transport...
The industrial production of tungsten powder is carried out by the reduction of tungsten oxide powder via hydrogen. In this process, the size of the W particles is limited to particle sizes larger than 100 nm. To get below this limit, alternative processes are needed. In the current work, the possibility of preparing W powder below 100 nm via a vap...
The production of very fine grained WC powders is of interest, due to the positive effects of smaller grain sizes on the mechanical properties of WC-Co hardmetals. With traditional processes starting with hydrogen reduction of WO3 to W and followed by carburization with carbon to WC, it is difficult to achieve nano-sized WC powders. In this study,...

The production of nano-sized WC powders is of high technical interest to increase the properties,
such as hardness, of high performance hardmetals, by using smaller grain sizes. Due to the
limitation of established industrial processes to achieve grain sizes in the nanometer range,
alternative processes for the production of nano-sized WC powders h...
Slag and copper samples of the Bronze Age found by the archaeologist Peter Trebsche in Prigglitz-Gasteil (Lower Austria) were analyzed using metallography, SEM, RFA and XRD. The determined composition of the different samples allow conclusions on the used ores, temperatures and in some extent also on technical properties used for the Bronze Age cop...
