Summary: Currently, IVIG is manufactured in batch through cold ethanol precipitation, which leads to a slow process with high space requirements. We have developed a continuous method using a tubular reactor to replace the batch precipitation method. This reactor, filled with static mixers for efficient cooling, allows for complete precipitation with the same yield and purity even with a residence time of only one minute. A tubular reactor with specific dimensions can process 4000 L of plasma per day, providing an opportunity to reduce the plant footprint or intensify existing manufacturing plants.

Summary: Fast reactor spent fuel plants reprocess plutonium-rich fuel to recover nuclear-grade uranium and plutonium using centrifugal extractors or mixer settler solvent extraction equipment. However, the high plutonium content in the spent fuel can lead to the formation of a third phase during the process, causing flooding and posing a risk of nuclear criticality or explosion in the evaporators. Therefore, continuous monitoring of the solvent extraction equipment is necessary to detect the onset of the third phase.

Summary: We developed a microfluidic device that utilizes dielectrophoresis to selectively trap and extract droplets from multiple trapping pockets. The device includes a main microchannel, five droplet-trapping pockets with side channels, and drive electrode pairs positioned around the trapping pockets. Agarose droplets containing biological samples were successfully trapped in the pockets due to flow resistance differences. Under an applied voltage of 500 V, target droplets were selectively extracted using dielectrophoretic force. The device allows for the screening of encapsulated single cells and the targeted extraction of desired droplets.

Summary: The study demonstrated the feasibility of aqueous reprocessing of U-Zr and U-Pu-Zr metallic alloy fuels using TBP as the extractant in an ejector mixer-settler. Continuous counter-current mixer settler runs showed quantitative extraction of U and U + Pu within five stages for U-Zr and U-Pu-Zr feed solutions, respectively. The proposed flow sheets suggest that the PUREX-based method for aqueous reprocessing of metallic fuels is achievable.

Summary: With the expansion of the lithium-ion battery market, the need for comprehensive recycling of cathode materials has increased. This study presents a comprehensive recovery system for the leachate from spent NCM cathode materials using microextraction equipment. A co-extraction method was developed to separate the MnCo-Ni from Li ions in the leachate. The extraction effects of different extractants were investigated, and a co-extraction pattern using a mixed extractant was established. The mechanism of saponification and extraction with the mixed extractant was explained using IR spectral results. The lithium ion was recovered via precipitation, resulting in regenerated lithium carbonate with high purity. The study successfully established a comprehensive extractive recovery process for Mn-Co-Ni with high recovery efficiencies.

Summary: In this study, novel solvent extraction and microfluidic technology were combined to effectively separate and extract Ca2+ ions. A serpentine microfluidic device was utilized to achieve complete separation of aqueous and organic phases. The extraction performance reached 23.40% at a residence time of 4.2 s. Optimization using the Box-Behnken design approach yielded an extraction performance of 62.34% for Ca2+ under the optimum conditions of pH 6.25, DC18C6 concentration of 0.015 M, and aqueous phase flow rate of 20 mu l/min. The experimental efficiency and microfluidic extraction in the novel serpentine microchannel were found to be superior to similar studies conducted under the same conditions.

Summary: The evolution of curricula in recent decades has led to diverse teaching approaches in the field of experimental science, promoting the development of research skills. However, the scientific method is rarely mentioned and more commonly referred to as a set of steps or structures for problem-solving, challenges, investigations, or assigned tasks. Problem-solving and critical thinking were identified as the most important skills developed through the knowledge and practice of the scientific method. There is a gap in the literature regarding the use of the scientific method and the development of research skills in non-STEM fields, highlighting the need for further studies to examine the effectiveness of teaching the scientific method in enhancing research skills in STEM and non-STEM areas.

Summary: Biofilms are living microorganism communities that pose a threat to the healthcare sector due to their association with health-related infections. This review provides an overview of biofilms and their formation, focusing on their relevance in biomedicine and advancements in materials to prevent or control biofilm formation. Biofilms are aggregates of cells in an extracellular matrix, offering protection to microorganisms in unfavorable environments. Staphylococcus spp., Escherichia spp., and Candida spp. are the most commonly reported microorganisms forming biofilms in medical implants and devices. In recent years, biofilms have been linked to health-associated infections and deaths globally. Smart, functional polymers show promise in combating biofilms through modification or synthesis of new materials.

Summary: The COVID-19 pandemic resulted in societal confinement and brought significant changes, such as reduced mobility, substantial changes in education with the development of distance learning and digital skills. Climate change and environmental pollution indicators decreased, but the quantification of the digital carbon footprint of remote work has not been systematically studied or calculated. This educational research aimed to determine the carbon footprint of digital activities in a company during the COVID-19 confinement by using Challenge-Based Learning methodology. The research program involved a one-semester academic program to develop energy auditing skills for students and validate evaluation instruments with a training partner. Data collection techniques, questionnaires, and analysis of energy consumption data were designed, allowing for the determination of the digital carbon footprint generated in the pilot company. Mitigation measures aligned with Sustainable Development Goals were proposed for a sustainable digital education trend.
