1. Iron-Catalyzed Laser-Induced Graphitization - Multiscale Analysis of the Structural Evolution and Underlying Mechanism 

   Dreimol, Christopher H.; Kursteiner, Ronny; Ritter, Maximilian; et al. (2024)

   Small

   The transition to sustainable materials and eco-efficient processes in commercial electronics is a driving force in developing green electronics. Iron-catalyzed laser-induced graphitization (IC-LIG) has been demonstrated as a promising approach for rendering biomaterials electrically conductive. To optimize the IC-LIG process and fully exploit its potential for future green electronics, it is crucial to gain deeper insights into its ...

2. Centralised rehearsal of decentralised cooperation: Multi-agent reinforcement learning for the scalable coordination of residential energy flexibility 

   Charbonnier, Flora; Peng, Bei; Vienne, Julie; et al. (2024)

   Applied Energy

   This paper investigates the use of deep multi-agent reinforcement learning (MARL) for the coordination of residential energy flexibility. Particularly, we focus on achieving cooperation between homes in a way that is fully privacy-preserving, scalable, and that allows for the management of distribution network voltage constraints. Previous work demonstrated that MARL-based distributed control can be achieved with no sharing of personal ...

3. Internal heating profiles for which downward conduction is impossible 

   Arslan, Ali; Fantuzzi, Giovanni; Craske, John; et al. (2024)

   Journal of Fluid Mechanics

   We consider an internally heated fluid between parallel plates with fixed thermal fluxes. For a large class of heat sources that vary in the direction of gravity, we prove that <delta T >(h)>=sigma R-1/3, where <delta T >(h) is the average temperature difference between the bottom and top plates, RR is a 'flux' Rayleigh number and the constants sigma,mu > 0 depend on the geometric properties of the internal heating. This result implies ...

4. Amygdala Reactivity, Antidepressant Discontinuation, and Relapse 

   Erdmann, Tore; Berwian, Isabel M.; Stephan, Klaas Enno; et al. (2024)

   Jama Psychiatry

   Importance:<bold> </bold>Antidepressant discontinuation substantially increases the risk of a depression relapse, but the neurobiological mechanisms through which this happens are not known. Amygdala reactivity to negative information is a marker of negative affective processes in depression that is reduced by antidepressant medication, but it is unknown whether amygdala reactivity is sensitive to antidepressant discontinuation or whether ...

5. Charge and Spin Dynamics and Destabilization of Shallow Nitrogen-Vacancy Centers under UV and Blue Excitation 

   Volker, Laura A.; Herb, Konstantin; Merchant, Darin A.; et al. (2024)

   Nano Letters

   Shallow nitrogen-vacancy (NV) centers in diamond offer opportunities to study photochemical reactions, including photogeneration of radical pairs, at the single-molecule regime. A prerequisite is a detailed understanding of charge and spin dynamics of NVs exposed to the short-wavelength light required to excite chemical species. Here, we investigate the charge and spin dynamics of shallow NVs under 445 and 375 nm illumination. With blue ...
