Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA Liquid-liquid extraction (LLE) is a separation technique used instead of distillation when either: (a) the relative volatilities of the compounds to be separated are very similar; (b) one or more of the mixture components are temperature sensitive even near ambient conditions; (c) the distillation would require a very low pressure or a very high distillate/feed...

This study presents a methodology to prepare 3D, biodegradable, foam-like cell scaffolds based on biocompatible side-chain liquid crystal elastomers (LCEs). Confocal microscopy experiments show that foam-like LCEs allow for cell attachment, proliferation, and the spontaneous alignment of C2C12s myoblasts.

The characteristics that enable us to distinguish one substance from another are called properties. Physical Properties of Matter A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter...

Source: Laboratory of Dr. Jay Deiner — City University of New York Extraction is a crucial step in most chemical analyses. It entails removing the analyte from its sample matrix and passing it into the phase required for spectroscopic or chromatographic identification and quantification. When the sample is a solid and the required phase for analysis is a liquid, the process is called solid-liquid extraction. A simple and broadly applicable form of solid-liquid extraction entails combining the...
FAQs
Cohesion draws neighboring molecules toward one another, contributing to surface tension at a liquid interface. That tension influences how a biological fluid maintains a continuous surface during movement. When interpreting experiments involving Liquid Properties, researchers therefore consider how temperature, pressure, and composition may affect observed behavior rather than treating the interface as chemically inactive.
Adhesion describes attraction between a liquid and another material, whereas cohesion acts among molecules within the liquid. Their balance helps determine capillary movement: adhesion can pull liquid along a surface, while cohesion supports continuity through the liquid. This distinction is relevant when analyzing water movement through plant tissues or liquid transport in narrow biological spaces.
Viscosity primarily determines resistance to flow, while density influences buoyancy and fluid distribution. These properties therefore affect different aspects of biological transport: viscosity helps explain how readily a fluid moves, whereas density helps predict how fluids distribute or support buoyant effects. Keeping them conceptually separate improves interpretation of physiological and laboratory fluid systems.
Temperature, pressure, and composition can change how a liquid responds and therefore influence observations of flow, surface interaction, and fluid distribution. Considering these conditions prevents researchers from attributing every change to a single property such as viscosity or density. The approach is important when comparing biological fluids, laboratory solutions, or modeled systems under different conditions.
A useful analysis begins by linking observed or modeled liquid behavior to the biological question. Researchers can examine flow resistance, interaction with surfaces, capillary movement, buoyancy, fluid distribution, and transport of dissolved substances. Organizing observations around these outcomes helps connect liquid characteristics to physiological transport or laboratory solution design.
Laboratory solution design requires attention to composition because dissolved substances can influence relevant physical and chemical behavior. Researchers also need to consider the intended transport or flow context, including surface interactions, viscosity-related resistance, and density-related distribution. This planning makes a solution more suitable for biological experiments and models.
In biology, liquid properties provide a framework for connecting fluid behavior with specific systems. They help researchers interpret blood circulation, water movement through plant tissues, membrane-associated processes, and cellular or extracellular fluids. The same framework also supports biological models, where flow resistance, surface interactions, buoyancy, and distribution clarify how transport occurs.
