Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Thermal expansion is extremely important when considering which materials will be used in systems that experience fluctuations in temperature. A high or low thermal expansion in a material may or may not be desirable, depending on the application. For instance, in a common liquid thermometer, a material with a high thermal expansion would be...

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.

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...

Here, we present a detailed protocol combining cryo-fixation and expansion microscopy methods (Cryo-ExM), allowing for high-resolution imaging with structural preservation adapted to various biological samples. Biological samples are frozen, embedded in a swellable polymer, denatured, expanded, and immunolabeled, enabling super-resolution imaging with standard light microscopes.

Solid-Liquid Extraction

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
Heating supplies energy that increases molecular motion within the liquid. As molecules move more vigorously, their average separation can increase, allowing the liquid to occupy more space. Because the liquid does not retain a fixed shape, this change appears as a higher level or altered volume within its container rather than as a permanent change in form.
A confined liquid cannot freely increase its volume when heating causes molecular separation to grow. The restricted space therefore converts the tendency to expand into greater pressure on the container walls or connected components. This distinction matters when evaluating closed tanks, pipelines, and other systems in which the liquid has limited room to accommodate thermal change.
The amount of liquid expansion depends primarily on the liquid itself and on the size of the temperature change. Different liquids respond differently to heating, so the same temperature increase does not produce an identical volume change in every fluid. These dependencies must be considered when selecting a liquid for measurement or designing equipment exposed to changing temperatures.
Water does not follow the simplest expected pattern of volume response near its freezing point. Its unusual behavior in that temperature region means that volume changes cannot always be estimated by assuming a uniform response to heating or cooling. This exception is important in physics because it shows that thermal expansion depends on the specific substance and temperature range.
A liquid-in-glass thermometer uses temperature-driven volume change to create a visible indication. As the liquid responds to heating or cooling, its changing volume is observed through the glass instrument and related to temperature. The choice of liquid and the temperature range influence the instrument’s response, making the thermal property useful for practical temperature measurement.
Fluid-based measuring devices can translate a liquid’s volume response into an observable measurement associated with temperature change. Their usefulness depends on the selected liquid and on how strongly its volume changes over the relevant range. This approach provides a practical way to monitor thermal conditions without relying only on direct observation of molecular motion.
Designers must account for both the volume increase available to the liquid and the pressure that may develop if expansion is restricted. The liquid’s identity and the expected temperature change determine the scale of the response. Applying these considerations helps tanks, pipelines, and related systems accommodate thermal variation rather than treating the contained fluid as dimensionally unchanged.
