Liquid-Liquid Extraction Strategies for the Isolation of Bioactive Heterocyclic Compounds
Abstract: Liquid-liquid extraction (LLE) is a widely employed technique for the isolation of bioactive heterocyclic compounds from natural products, fermentation broths, and synthetic mixtures. The efficiency of LLE depends on several factors, including solvent selection, pH manipulation, salting-out effects, and temperature control. Conventional solvent systems, such as water-organic solvent pairs, are commonly used, while advanced strategies, including ionic liquids (ILs), deep eutectic solvents (DESs), ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE), …

Liquid Architecture: Cultural Narratives, Spatial Metaphors, and the Evolution of Fluid Form
Abstract: Liquid architecture represents a fundamental rethinking of architectural space, moving away from the long-standing assumption that buildings must be static, permanent, and formally fixed. Rather than understanding architecture as an object defined by rigid boundaries and stable geometry, liquid architecture proposes space as a fluid condition shaped by movement, atmosphere, perception, and cultural meaning. Rooted in cultural theory, phenomenology, and spatial anthropology, this approach views architecture as an evolving narrative …

Several Phases of Binary Liquid Mixture
Abstract: The system’s overall composition, heat, and stress can all be changed independently. Instead of using parameters like the coordinates of a three-dimensional phase diagram, we often generate a twodimensional phase transformation that is either a thermal diagram at a specified pressure or its composition graph at a fixed temperature. The location of the system points on one of these diagrams correlates to a certain heat, stress, and normal phenomenon. As …
