Here we present a protocol for performing reactions in simple reaction vessels under low-to-moderate pressures of CO2. The reactions can be performed in a variety of vessels simply by administering the carbon dioxide in the form of dry ice, without the need for costly or elaborate equipment or set-ups.

Determining the Ice-binding Planes of Antifreeze Proteins by Fluorescence-based Ice Plane Affinity

2014
Antifreeze proteins (AFPs) bind to specific planes of ice to prevent or slow ice growth. Fluorescence-based ice plane affinity (FIPA) analysis is a modification of the original ice-etching method for determination of AFP-bound ice planes. AFPs are fluorescently labeled, incorporated into macroscopic single ice crystals, and visualized under UV light.
FAQs
Heat entering the solid supplies the energy needed for sublimation, so warmer surroundings generally increase the release of carbon dioxide gas. The process also depends on how readily heat reaches the material. In a chemistry experiment, controlling the surrounding temperature helps regulate gas production and demonstrates the connection between energy transfer and phase change.
Surface area influences how much of the solid can exchange heat with its surroundings at the same time. A larger exposed area can support faster sublimation, while a smaller area can slow gas release under otherwise similar conditions. This variable matters when an experiment requires a more predictable carbon dioxide supply or cooling effect.
Dry ice provides a direct example of sublimation, in which a solid changes into a gas without passing through a liquid state at atmospheric pressure. The resulting carbon dioxide gas also illustrates how a phase change can alter the physical state and movement of matter. These observations connect laboratory demonstrations with heat transfer and gas behavior.
When carbon dioxide released from dry ice contacts warm, humid air, the interaction produces visible fog. The fog makes the otherwise invisible gas movement easier to observe, allowing a demonstration to connect gas release with atmospheric moisture and temperature differences. Its appearance therefore provides a visual outcome of heat transfer and changing environmental conditions.
Dry ice can remove heat from a reaction mixture and help establish a controlled low-temperature environment. This application emphasizes the transfer of thermal energy from the mixture toward the colder solid as sublimation occurs. In chemistry, the approach is useful when observing how cooling conditions influence an experiment, provided the material is handled safely and ventilation is considered.
The setup should account for three linked factors: the desired gas release or cooling effect, the surrounding temperature, and the available ventilation. Surface area also affects the release rate, so the physical arrangement can influence the outcome. Safe handling remains essential because the material combines intense cooling with the production of carbon dioxide gas.
