Methods of Making Lithium-Ion Batteries Membrane
Due to the growing demand for eco-friendly products, lithium-ion batteries (LIBs) have gained widespread attention as an energy storage solution. With the global demand for clean and sustainable energy, the social, economic, and environmental significance of LIBs is becoming more widely recognized. LIBs are composed of cathode and anode electrodes, electrolytes, and separators. Notably, the separator, a pivotal and indispensable component in LIBs that primarily consists of a porous membrane material, warrants significant research attention.

Kappa-2 Carrageenans
Hybrid carrageenans, also called kappa-2 (K2) or weak kappa, are a class of sulfated polysaccharides with thermo-reversible gelling properties in water and are extracted from a specific family of red seaweeds. K2 are known in the industry for their texturizing properties which are intermediate between those of kappa-carrageenans (K) and iota-carrageenans (I). As such, K2 are gaining industrial interest, as they can replace blends of K and I (K + I) in some niche applications.

Strategies of Renal Drug Delivery Systems
The kidneys are the most important organs in the human urinary system, selectively filtering blood and metabolic waste into urine via the renal glomerulus. Based on charge and/or molecule size, the glomerular filtration apparatus acts as a barrier to therapeutic substances. Therefore, drug distribution to the kidneys is challenging, resulting in therapy failure in a variety of renal illnesses. Hence, different approaches to improve drug delivery across the glomerulus filtration barrier are being investigated. Nanotechnology in medicine has the potential to have a significant impact on human health, from illness prevention to diagnosis and treatment. Nanomaterials with various physicochemical properties, including size, charge, surface and shape, with unique biological attributes, such as low cytotoxicity, high cellular internalization and controllable biodistribution and pharmacokinetics, have demonstrated promising potential in renal therapy. Different types of nanosystems have been employed to deliver drugs to the kidneys.

Covalent Adaptable Networks in Recycling of Polyurethane Plastics
The global plastic waste problem has created an urgent need for the development of more sustainable materials and recycling processes. Polyurethane (PU) plastics, which represent 5.5% of globally produced plastics, are particularly challenging to recycle owing to their crosslinked structure. Covalent adaptable networks (CANs) based on dynamic covalent bonds have emerged as a promising solution for recycling PU waste. CANs enable the production of thermoset polymers that can be recycled using methods that are traditionally reserved for thermoplastic polymers. Reprocessing using hot-pressing techniques, in particular, proved to be more suited for the class of polyurethanes, allowing for the efficient recycling of PU materials.

Hot-Melt Adhesive Composition
Hot-melt adhesives (HMAs) are thermoplastic materials that can bond various substrates by solidifying rapidly upon cooling from the molten state, and their modification with organosilicon compounds can result in crosslinking behavior, characteristic of gels. Organosilicon compounds are hybrid molecules that have both inorganic and organic components and can enhance the properties and performance of HMAs.

Organic Fouling Influencing Factors in Membrane Separation Processes
Organic matter such as raw wastewater organic matter (WOM), effluent organic matter (EOM), and natural organic matter (NOM) can contribute to membrane fouling in membrane separation processes. These organic compounds can include proteins, lipids, amino acids, polysaccharides, colloidal particles, humic and folic acids, and other complex organic molecules. These compounds can accumulate on the membrane surface or inside pores, leading to fouling. The accumulation of organic matter on the membrane surface can also lead to the formation of a biofilm, which can further exacerbate fouling and reduce the efficiency of the membrane separation process.

Capillary Electrophoresis Analysis of Alkaline Phosphatase
Alkaline phosphatase is a vital enzyme used in separation studies and as a biomarker for liver, bone, and certain cancer conditions. Its stability and specific properties enable insights into enzyme behavior, aiding in the development of detection methods with broader applications in various scientific fields. Alkaline phosphatase has four main isoenzymes: germ cell alkaline phosphatase (GCAP), intestinal alkaline phosphatase (IAP), placental alkaline phosphatase (PLAP), and tissue-nonspecific alkaline phosphatase (TNAP), each with distinct roles. TNAP is found in the liver, kidney, and bones, playing a role in bone mineralization. Separation techniques like electrophoresis and chromatography are valuable for studying enzymes and proteins, revealing insights into their structure and function in pharmaceutical research and post-translational modification (PTM) studies.
