Phonons are quantized vibrational excitations of the crystal lattice. These quasiparticles play a crucial role in understanding many properties of the solid-state system. [...]

The development of magnetic resonance imaging (MRI) based biomarkers is a constant endeavorin the field of clinical neuroscience. Although these biomarkers hold great potential, only few havebeen adopted for routine clinical use. [...]

Graphene (Gr) has obtained significant attention in the realm of advanced information technologies due to its remarkable electronic properties, such as high carrier mobility, an unusual quantum Hall effect, and long spin lifetimes at room temperature. These attributes make Gr a promising candidate for various applications, particularly in spintronics. [...]

In view of the post-Moore’s law era, new computational paradigms that could serve as powerful alternatives to the classical computing are under development. One of those paradigms is Quantum Computing (QC). [...]

Several influential factors impact pedestrian movement within crowds, making their analysis complex and challenging. To address this, we employ a simplified system referred to as single-file. [...]

Perovskite-structured oxygen transport membranes hold great potential for the energy-efficient separation of pure oxygen from air. While many materials have demonstrated excellent performance, their industrial application still remains limited due to the lack of material stability, which hinders long-term operation under the required conditions. [...]

The electrical contact resistance at solid oxide cell (SOC) contacts is a key aspect which contributes to ohmic losses in an SOC stack. These resistances are primarily dependent on the mechanical contact pressures applied in the active area, which are influenced by non-idealities caused by manufacturing limitations. [...]

Climate change and the depletion of essential resources like phosphorus are challenging agriculture by reducing water and fertilizer availability and ultimately threatening the security of the human food supply. Knowledge of how plants respond to changing environmental conditions is required to cope with these challenges. [...]
