Cassava (Manihot esculenta) is an important crop for food security in tropical and subtropical regions, with roots containing up to 85% starch on a dry weight basis [25]. Understanding root system architecture is essential for breeding programs aimed at improving yield and stress tolerance [1]. [...]

Focused Ion BeamFocused Ion Beam (FIB) technology has become a crucial tool in microfabrication, microelectronics, and materials science due to its ability to precisely modify materials at the micro and nanoscale. FIB systems may produce sub-micron sized ion beams, such as gallium, using liquid metal ion sources. [...]

The reference AmSel system extracts americium, Am(III), from PUREX raffinate solutions. It is based on the co-extraction of Am(III), Cm(III) and Ln(III) using the TODGA extracting agent, followed by selective extraction of Am(III) using a water-soluble ligand, SO3-Ph-BTBP.In addition to published data, the coordination of Ln(III) with SO3-Ph-BTBP and its protonation was studied in detail using UV-Vis and NMR. [...]

New water-soluble ligands to selectively strip Am(III) from a solvent loaded with Am(III), Cm(III) and Ln(III) were developed and tested. The former reference ligand, SO3-Ph-BTBP, has the drawback of containing sulphur atoms. [...]

A new CHON AmSEL system was developed based on PrOH-BPTD as the americium-selective complexant. Previous investigations (see deliverable D1.1) found it to show sufficient efficiency and selectivity for americium over trivalent lanthanides and curium. [...]

This document provides the results of an experimental demonstration and validation of a spiked AMSEL flowsheet test, which was conducted at FZJ. The AmSEL process uses TODGA as an extractant and SO3-Ph-BTBP as an Am(III) selective complexant. [...]

This document provides the approach adopted to develop a model for the AmSEL process, using TODGA as an extractant and SO3-Ph-BTBP as a complexing reagent. The constant of the model was determined using single-stage centrifugal contactor experiments. [...]
