The AgraSim experiment at Forschungszentrum Jülich is a unique laboratory for research on the impact of climate conditions on agricultural ecosystems and for the optimization of climate models. For the high-resolution 3D tomography of soil parameters, we develop a modular Ground Penetrating Radar (GPR) monitoring system with 39 DAQ modules, each containing 64 antennas. [...]

Metal-free organic electrode materials are of increasing interest due to their environmental compatibility, natural abundance, and structural versatility. Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) is an intrinsically conductive polymeric salt that has emerged as a multifunctional electrode material, serving both as a conductive additive and as binder in energy storage applications. [...]

N-Aryl sulfamoyl fluorides (ArSAFs) are hydrolytically stable motifs widely used in drug design, yet their suitability for radiotracer development has not been explored. Here, we report the efficient radiosynthesis of [18F]ArSAFs by base-free sulfur(VI) fluoride exchange (SuFEx), affording high molar activities from nanomolar precursor amounts. [...]

Emerging Kolmogorov–Arnold networks (KANs) replace the linear weights of neural networks with trainable nonlinear functions. This modification is particularly attractive for scientific computing, where KANs can match the accuracy of conventional multilayer perceptrons (MLPs) while reducing model size by up to 100×. [...]

Logic-in-memory (LiM) has emerged as a promising paradigm to address the von Neumann bottleneck by integrating data storage and in-situ computation. Resistive random-access memory (RRAM) is a strong candidate for LiM owing to its non-volatility, fast switching characteristics, and compatibility with CMOS integration. [...]

Libyan Desert Glass (LDG) is an ~29 million years old, silica-rich glass found in Western Egypt. Whether this glass formed in an impact cratering context associated with the hypervelocity collision of a cometary/asteroidal body or radiative heating during an airburst is debated. [...]

The proposed prototype Canadian Compact Accelerator-driven Neutron Source (PC-CANS) presents a cost-effective solution to address the shrinking global availability of neutron beams. Designed to support a range of applications, including Small Angle Neutron Scattering (SANS), neutron imaging, boron neutron capture therapy, and radioisotope production, PC-CANS aims to restore and enhance Canada’s neutron science capabilities. [...]

Proton-conducting electrolysis cells (PCECs) are critical to sustainable energy technologies, as they enable the production of undiluted hydrogen that can be readily compressed and stored. These cells are essential for establishing a hydrogen economy. [...]
