The ever-increasing demand for data and computing power ignited by data driven technology raises the desire for a new generation of faster and more efficient computing devices. Furthermore, the sheer amount of data generated requires storage devices to pack information as dense as possible. [...]

Solid Oxide Cells (SOCs) are promising energy conversion devices with applications in both electricity generation and chemical fuel production. Fuel Electrode-Supported Cells (FESCs) particularly offer a robust architecture, but their performance and reliability are heavily dependent on the manufacturing process of a porous substrate material. [...]

Spin-based phenomena are the central concept in the field of spintronics, where efficient spin current generation, spin-to-charge conversion, and spin transport are the key concepts for the development of next-generation electronic devices. With the extensive availability of femtosecond lasers a new research field of ultrafast spintronics has opened up, aiming to understand spin-transport on the ultrafast time scales. [...]

As conventional CMOS technology approaches its scaling limits, alternative memory and logic device concepts are being actively pursued. Among these, resistive and ferroelectric switching mechanisms have emerged as promising candidates for non-volatile memory technologies due to their potential for high density, low power consumption, and compatibility with existing semiconductor processes. [...]

This work uses proton exchange membrane water electrolyzers as an example to provide a comprehensive understanding of the relationship between catalyst layer morphology, manufacturing processes, and electrochemical performance. Combining microscopy techniques with modern evaluation methods establishes a reliable foundation for characterizing and developing the catalyst layer’s structural and electrical features. [...]

The growing demand for renewable energy and the need for efficient energy conversion technologies have spurred significant interest in solid oxide cells (SOCs). Recently, proton-conducting ceramic cells (PCCs) have gained considerable attention due to their potential to operate at lower temperatures than oxygen-ion-conducting SOCs. [...]

Transformation towards renewable energy sources and reduction of greenhouse gas emissions to mitigate climate change are among the most severe challenges of humankind today. Energy storage bears the potential to enable this transformation when applied as grid energy storage, which could enhance the utilization of renewable energy sources [...]
