Test und Simulation von Detektorkomponenten des ASPIRIN-Detektors am Experiment ATRAP

open access: yes, 1998
Goal of the ATRAP - Experiment is to capture the simplest atoms of antimatter, the Anti-Hydrogen-Atom $\overline{H}^{0}$ in a trap, where it can be cooled and detected in order to perform high precision optical spectroscopy. Subject of this work are studies in preparation of the construction of the ASPIRIN-Detector being a realtime imaging Antihydrogen

Evaluating Bicarbonate Electrolyzer Configurations for Energy‐Efficient Formate Production

open access: yesAdvanced Sustainable Systems, EarlyView.
Reactive carbon capture (RCC) with bicarbonate electrolyzers (BEs) offers an efficient alternative to gas‐fed CO2 electrolyzers by eliminating regeneration and pressurization steps. This study optimizes BE configurations and compares RCC chains to gas‐fed carbon chains for formate production.

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

open access: yesAdvanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

open access: yesAdvanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.
