“…Even though the thickness of the membrane was chosen to be as low as possible (30 µm), its resistance still accounted for ≈30% of the total resistance. As demonstrated in the study from Theisen et al 13 , R mem will increase at lower distribution coefficient. Nonetheless, our simulation enables us to estimate R mem and shows that it is of the same order of magnitude as R org .…”

“…In terms of chip design, guide structure [6][7][8][9][10] and droplet [2,[11][12][13][14][15][16] technologies require a highly stable flow rate with careful injection to maintain separation with higher risk of interface rupture. Recently, Dunne et al developed a flow technique based on magnetic flow freeing themselves from the excessive hydrostatic pressure stemming from wall friction.…”

First online X‐ray fluorescence characterization of liquid‐liquid extraction in microfluidics

Liquid-liquid extraction is a complex chemical purification process, which is associated with many thermodynamic and kinetic values. This makes its application in the recycling industry difficult, as it deals with waste streams that have highly variable compositions. In this regard, modelling an extraction process using microfluidics proves to be a useful approach to allow rapid adaptation to such composition changes, if development can be shown to be more accurate, faster, and safer than the classical batch approach with separate analysis. Here, the first automated microfluidic tool integrated with online X-ray fluorescence (XRF) is reported to study liquid-liquid extraction processes by enabling metal concentration quantification. The measurement is automated and performed for both aqueous and organic phases to improve accuracy.Overall, this fully automated approach shows that: (i) Thermodynamic and kinetic values associated with these processes can rapidly and efficiently be obtained simultaneously (in less than 13 hours with a resulting liquid use of less than 20 mL). (ii) Numerical simulations are consistent with the experimental data and provide rare insights regarding the respective contributions to the overall kinetic of the extraction system.

“…This technique is proposed as a first step for Cu separation from bulk target material, which can be then followed by further purification using chromatographic methods [ 57 , 58 ]. Recently, the dithizone-based solvent extraction and back extraction of Cu from large excess of Zn have been implemented in a microfluidic system [ 59 ].…”

Is the 67Cu production worldwide feasible for expanding preclinical and clinical studies? How can we face the ingrowing demands of this emerging and promising theranostic radionuclide for personalized therapies? This review looks at the different production routes, including the accelerator- and reactor-based ones, providing a comprehensive overview of the actual 67Cu supply, with brief insight into its use in non-clinical and clinical studies. In addition to the most often explored nuclear reactions, this work focuses on the 67Cu separation and purification techniques, as well as the target material recovery procedures that are mandatory for the economic sustainability of the production cycle. The quality aspects, such as radiochemical, chemical, and radionuclidic purity, with particular attention to the coproduction of the counterpart 64Cu, are also taken into account, with detailed comparisons among the different production routes. Future possibilities related to new infrastructures are included in this work, as well as new developments on the radiopharmaceuticals aspects.
