Following the recovery of U and Pu from used nuclear fuel, Am becomes the primary contributorto the long-term radiotoxicity and heat load of the remaining high level waste.The AmSel (Americium Selective) process has been developed for the selective strippingof Am from PUREX (Plutonium Uranium Reduction Extraction) raffinate. It is basedon the combined use of two ligands with opposite selectivity and solubility, which workin a push-pull system, allowing a satisfactory separation of Am from Cm and all the lanthanides(Ln).

Structurally, the mineral clinoatacamite Cu$_2$Cl(OH)$_3$ is closely related to the kagome material herbertsmithite ZnCu$_3$Cl$_2$(OH)$_6$, however, its kagome motif of Cu sites is embedded into a low-symmetry crystal structure. The magnetic ground states of clinoatacamite below an ordering temperature of 18.1 K have remained inconclusive to date. [...]

We consider an inverse shape problem for recovering an unknown simply supported obstacle in two dimensions from near–field point–source measurements for the biharmonic Helmholtz equation. The measured data consist of the scattered field and its Laplacian on a closed measurement curve surrounding the obstacle. [...]

Modern scientific workflows increasingly span diverse computing architectures, yet executing a single computational model across disparate systems often forces researchers to maintain fragmented, site-specific pipelines. In this paper, we address this challenge within the domain of computational neuroscience by presenting a unified, cloud-based workflow orchestrated via EBRAINS JupyterLab. [...]

Deploying complex, distributed scientific workflows across diverse HPC sites is often hindered by site-specific dependencies and complex build environments. This paper investigates the design and performance of portable HPC container images capable of encapsulating MPI- and CUDA-enabled software stacks without sacrificing bare-metal performance. [...]
