The desired achievement of a circular economy presupposes that such rejects could be recovered. This paper presents a two- staged process route that allows one to recover graphite and conductive carbon black from already coated negative electrode foils in a water-based and function-preserving mannerand it makes it directly usable as a particle suspension for coating new negative electrodes More details Edition10 Internal reference2973 Open publication →

Development of Optimized IgG-Binding Affinity Materials AuthorYasmin Kaveh Baghbaderani Year2024 SourceDissertation LanguageEnglish Pages1-189 3138LRPSALUMiReader PSA; Protein A-mediated IgG capture methods are still the workhorse of robust downstream platform processes for monoclonal antibodies (mAbs). During the course of this worktwo main approaches were pursued to optimize IgG separation techniques. The second approach focused on the magnetic separation of IgG using bare iron oxide nanoparticles (BION) as the carrier material for the immobilization of large B8 ligand with the wild-type linker sequence. Die IgG-Separation mit Protein A-Materialien ist nach wie vor das Herzstück zuverlässiger Plattformprozesse für die Reinigung monoklonaler Antikörper (mAbs). Im Rahmen dieser Arbeit wurden zwei Konzepte zur Optimierung dieser Separationsprozesse verfolgt. Beim Ersten lag der Fokus auf die Nutzung von unterschiedlichen Interdomänenlinkern für rational designte Liganden bestehend aus polymerisierten IgG-bindenden Domänen.Der zweite Ansatz fokussierte sich auf die Verwendung von unmodifizierten Eisenoxid- Nanopartikeln (BION) für die Immobilisierung der Protein A-basierten Liganden und für die magnetische Separation von IgG. Sedimentation Velocity of BION For the assessment of the sedimentation velocity of BION samples 2 more the LUMiReader Separation Analyser (LUM GmbHGermany) was used. The samples were applied into a customized cuvette modified with a magnet at the bottom in order to measure the sedimentation in a magnetic field. The particles were diluted to 0.5 g L-1 and 1 mL sample was pipetted into the cuvette. The measurement was over 6 min. The cumulative velocity distribution Q was evaluated at 410 nm.

Direct recycling of carbon black and graphite from an aqueous anode slurry of lithium-ion batteries by centrifugal fractionation AuthorTolga Yildiz, Patrick Wiechers, Hermann Nirschl, Marco Gleiß Year2024 SourceNext Energy LanguageEnglish Pages100082 2916LSLUMiSizerenergy storage 19 more batteryDirect battery recyclingDecanter centrifugeGraphiteCarbon blackParticle size analysisSedimentation analysisCentrifugation is a promising method for direct recycling of lithium-ion battery materials from an aqueous slurry. investigates the continuous fractionation of an aqueous anode slurry into the active material graphite and the conductive carbon black in a decanter centrifuge. To evaluate the separation successtwo analytical methods utilizing the different particle sizes and sedimentation velocities of the materials were developed and tested. Both methods can detect graphite separation efficiencies up to 90 % based on centrate samples. The detectability of carbon black in sediment samples is more sensitive for the sedimentation analysiswhich can measure carbon black separation efficiencies down to 1 %in contrast to the particle size analysisallowing the detection of separation efficiencies down to 10 %. Both methods provide similar results in terms of assessing the separation process in the lab-scale decanter centrifuge. At a centrifugal acceleration of 352 g and a volume flow of 66 l/hmore than 90 % graphite can be separated with a low carbon black deposition between 10% and 20 %. Thusa high recovery of graphite and carbon black from an aqueous anode slurry by using a decanter centrifuge is basically possibleand the LUMiSizerⓒtwo analytical instruments are available offering the potential to differentiate the materials based on the different particle sizes and sedimentation velocities in the centrifugal field.Cumulative intensity distribution of a pure carbon black and graphite slurry measured by LUMiSizerA two-stage sedimentation analysis with the LUMiSizerⓒ fulfills these requirementsThe detectability of carbon black in a graphite- rich slurry by the sedimentation analysis with the LUMiSizerⓒis significantly more sensitive with a carbon black fraction of down to 1 % due to the strong light extinction behavior of carbon black.

In many applicationsits use requires processing in an aqueous medium. Howeversince it is highly hydrophobic 10 more fullerene can only be dispersed in water to the ppm scale. Thereforewe propose two different processes to disperse high amounts of fullerene in water: Ouzo effect for which fullerene is first solubilized in a water-miscible organic solventand emulsion-evaporation where a water-immiscible solvent is used. To improve dispersibility of fullerene in waterwe used an amphiphilic polymer as a stabilizerthat displays hydrophobic interactions as well as π-π stacking with fullerene. fullerenesuspensionsOuzo effetemulsion-evaporationAnalytical centrifugation (LUMiSizer) was also used to characterize particles which size is close to or beyond the upper limit of light scatteringLS More details EditionNominated for LUM Young Scientist Award 2024- Abstracts LocationBerlin, Germany, 10-11 June 2024 Internal reference2922 Open publication →
