Heating and Cooling Curves

When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves. For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Embryonic stages are the most susceptible to xenobiotics. Although chemical toxicity depends on salinity, no method exists to test the salinity dependence of toxicity to aquatic organisms. Here, we describe a new and high-throughput method for determining the salinity dependence of toxicity to aquatic embryos.

A Hypertonic Saline Injection Technique for Inducing Glaucoma in Rats

This video demonstrates glaucoma induction in an anesthetized rat by injecting hypertonic saline into the episcleral vein. The saline enters the trabecular meshwork via Schlemm's canal, causing tissue scarring, which blocks aqueous humor outflow and raises intraocular pressure. The elevated pressure damages retinal ganglion cells, leading to glaucoma.

We present a parametric driving method to cool an ultracold Fermi gas in a crossed-beam optical dipole trap. This method selectively removes high-energy atoms from the trap by periodically modulating the trap depth with frequencies that are resonant with the anharmonic components of the trapping potential.
FAQs
The cooling effect depends on two heat-transfer routes. Conduction moves heat directly from the warmer tissue, device, or experimental surface into the contacting saline, while convection distributes that absorbed heat through the fluid. Together, these processes allow the solution to draw heat away rather than leaving it concentrated at one contact point.
Once saline absorbs heat, its temperature can increase and reduce its ability to remove additional heat. Circulating the solution or replacing it with chilled saline helps sustain the temperature difference between the fluid and the warmer surface. This limits temperature increases and makes cooling more consistent during an experiment or procedure.
Controlled thermal exposure helps investigators distinguish the intended treatment effect from unintended heating of surrounding material or tissue. In studies of heat-based ablation or surgical procedures, maintaining appropriate cooling can support protection of nearby healthy tissue and help define the boundary, or treatment margin, between treated and non-target regions.
A basic workflow places chilled saline in contact with the warmer tissue, device, or experimental surface so heat can transfer into the solution. The saline is then circulated or replaced as it warms, maintaining cooling during the relevant handling or testing period. This approach can be adapted to the specific experimental system under study.
During heat-based ablation research, cooling can help manage thermal exposure near the treatment area, while surgical studies can use it to help protect adjacent healthy tissue. These effects are relevant when researchers need to evaluate treatment margins, because temperature control may help separate the intended target region from nearby non-target tissue.
In laboratory models, stable thermal conditions can reduce variation during tissue handling and testing. Applying chilled saline and sustaining its cooling action through circulation or replacement provides a way to control the temperature environment around the model. More consistent conditions can make comparisons among experimental samples or procedures easier to interpret.
