    Abstract While there has been a growing interest on the concept of Circular Economy (CE), its correlation with sustainability remains controversial. In this work, the combination of Statistical Entropy Analysis (SEA) and Life Cycle Assessment (LCA) is proposed as a new methodology to evaluate recycling processes from the perspective of materials circularity and environmental impacts using a Li-ion battery recycling process as a case study. This work addresses the need of quantitative circularity indicators, as SEA evaluates the concentration of materials at a systems level, while LCA measures the environmental impact of recycling processes in comparison with virgin raw materials production. It was found that process optimization points can be found by simultaneously accounting for materials recovery and the LCA categories of global warming potential, ozone depletion and mineral resource scarcity. Furthermore, a strong correlation was found for the first time between the recovery of critical elements and the environmental impact of raw materials production. The proposed methodology thus offers a robust analysis of a product lifecycle that aids in its design and optimization from the CE perspective.

    Abstract The growing electric vehicle industry has increased the demand for raw materials used in lithium-ion batteries (LIBs), raising concerns about material availability. Froth flotation has gained attention as a LIB recycling method, allowing the recovery of low value materials while preserving the chemical integrity of electrode materials. Furthermore, as new battery chemistries such as lithium titanate (LTO) are introduced into the market, strategies to treat mixed battery streams are needed. In this work, laboratory-scale flotation separation experiments were conducted on two model black mass samples: i) a mixture containing a single cathode (i.e., NMC811) and two anode species (i.e., LTO and graphite), simulating a mixed feedstock prior to hydrometallurgical treatment; and ii) a graphite-TiO

    Abstract Background: Multimodal histology image registration is a process that transforms into a common coordinate system two or more images obtained from different microscopy modalities. The combination of information from various modalities can contribute to a comprehensive understanding of tissue specimens, aiding in more accurate diagnoses, and improved research insights. Multimodal image registration in histology samples presents a significant challenge due to the inherent differences in characteristics and the need for tailored optimization algorithms for each modality.
    Results: We developed MMIR a cloud-based system for multimodal histological image registration, which consists of three main modules: a project manager, an algorithm manager, and an image visualization system.
    Conclusion: Our software solution aims to simplify image registration tasks with a user-friendly approach. It facilitates effective algorithm management, responsive web interfaces, supports multi-resolution images, and facilitates batch image registration. Moreover, its adaptable architecture allows for the integration of custom algorithms, ensuring that it aligns with the specific requirements of each modality combination. Beyond image registration, our software enables the conversion of segmented annotations from one modality to another.

    Abstract Deep learning techniques have recently yielded remarkable results across various fields. However, the quality of these results depends heavily on the quality and quantity of data used during the training phase. One common issue in multi-class and multi-label classification is class imbalance, where one or several classes make up a substantial portion of the total instances. This imbalance causes the neural network to prioritize features of the majority classes during training, as their detection leads to higher scores. In the context of object detection, two types of imbalance can be identified: (1) an imbalance between the space occupied by the foreground and background and (2) an imbalance in the number of instances for each class. This paper aims to address the second type of imbalance without exacerbating the first. To achieve this, we propose a modification of the copy-paste data augmentation technique, combined with weight-balancing methods in the loss function. This strategy was specifically tailored to improve the performance in datasets with a high instance density, where instance overlap could be detrimental. To validate our methodology, we applied it to a highly unbalanced dataset focused on nuclei detection. The results show that this hybrid approach improves the classification of minority classes without significantly compromising the performance of majority classes.

    Abstract Celiac disease (CD) is an autoimmune disorder that produces inflammation in the gut mucosa, affecting nutrient digestion and absorption. CD affects 0.3% to 1.0% of the world's population and only 15% have a clinical diagnosis. The only effective treatment is a gluten-free diet. The objective of this study was to develop a dough for gluten-free pasta prepared with mixtures of flours from corn, amaranth, soy, and rice. According to the FAO standard of 1975, the resultant mixtures should have a protein content greater than 11.0% and a chemical rating of not less than 70. Three mixtures were obtained: corn‒soy (81-19), corn‒rice‒soy (48-37-15), and corn‒rice‒amaranth (49-32-14). To improve the handling of the pasta and its physical characteristics (sedimentation, degree of absorption, and cracked shaped pasta) compared to a control (commercial) gluten-free pasta, carboxymethylcellulose, an emulsifier (distilled monoglycerides), and egg albumin were added at concentrations of 0.3, 0.5, and 5.0%, respectively. The corn flour was pregelatinized, and the extrusion was repeated twice. The experimental pasta had a protein content of 14.0%, which was higher than the commercial pasta (4.5%), and a gluten content of less than 20 mg/kg which, according to the Codex Alimentarius International Food Standard (2015), it is considered gluten-free. The corn‒rice‒soy pasta obtained had an acceptance and liking similar to a commercial brand. This pasta may widen the gluten-free products commercially available to CD patients in Mexico, which nowadays is limited and expensive. PRACTICAL APPLICATION: Raw materials available in our country were selected to promote their consumption and diversify the ingredients used in the production of gluten-free products. The pasta obtained presented a higher nutritional content than a commercial gluten-free pasta and was comparable to that of a pasta made with wheat.

    Abstract A new method based on thermogravimetric analysis was developed to measure the graphite content in battery material mixture. This approach exploits the thermochemical reduction of cathodic Li-transition metal oxides with anodic graphite at elevated temperatures under an inert atmosphere. Using known composition artificial mixtures, a linear correlation between cathode mass loss and sample graphite content was observed. The method was validated using industrial black mass samples and characterized traditionally to estimate and rationalize potential error sources. Thermal degradation profiles of industrial battery waste reflected those in the artificial system, demonstrating its applicability. This work also demonstrates that thermogravimetric degradation profiles can distinguish between a cathode consisting of single or multiple Li-metal oxides. Although accuracy depends on active component mixture content and impurities, it is demonstrated that the method is useful for a fast graphite content estimation. Unlike other graphite characterization techniques, the method proposed is simple and inexpensive.
