Summary
Confined water behaves differently from bulk water, showing unique properties like remaining liquid at very low temperatures. This impacts material science, geology, and understanding life in extreme environments.
Area of Science:
- Interdisciplinary science
- Physical chemistry
- Biophysics
Background:
- Water's behavior is crucial in biology and geology.
- Confined water properties depend on geometry and interfaces.
- Understanding confined water is key to material science.
Purpose of the Study:
- To review water behavior in nano-sized confinements.
- To explore water in living cells and biomolecular hydration shells.
- To highlight differences between confined and bulk water.
Main Methods:
- Review of existing literature on confined water.
- Analysis of water structure and dynamics under confinement.
- Examination of nucleation and crystallization in confined systems.
Main Results:
- Confined water exhibits distinct nucleation, crystallization, and dynamics.
- Water's hydrogen bond network is altered in confinement.
- Water remains liquid at extremely low temperatures (-45°C to -120°C) in nano-confinements.
Conclusions:
- Confined water properties differ significantly from bulk water.
- Understanding confined water offers insights into fundamental physics.
- This knowledge can enhance our understanding of life in subzero environments.

01:03Sublimation
723
Sublimation is the direct transformation of a solid to a gaseous state. For instance, at standard pressure and room temperature, solid carbon dioxide sublimes to gaseous carbon dioxide. The phase diagram depicts the conditions required for sublimation. This process occurs at the solid-gas phase boundary and is not observed above the triple point of the substance. The reverse of sublimation is called deposition, where a gaseous substance condenses directly into a solid. Sublimation and...

01:23States of Water
50.5K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

02:39Phase Diagrams
39.9K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

3.2K
Conventional electron microscopy (EM) involves dehydration, fixation, and staining of biological samples, which distorts the native state of biological molecules and results in several artifacts. Also, the high-energy electron beam damages the sample and makes it difficult to obtain high-resolution images. These issues can be addressed using cryo-EM, which uses frozen samples and gentler electron beams. The technique was developed by Jacques Dubochet, Joachim Frank, and Richard Henderson, for...

02:39Phase Transitions: Melting and Freezing
12.3K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

01:24Superconductor
1.1K
A substance that reaches superconductivity, a state in which magnetic fields cannot penetrate, and there is no electrical resistance, is referred to as a superconductor. In 1911, Heike Kamerlingh Onnes of Leiden University, a Dutch physicist, observed a relation between the temperature and the resistance of the element mercury. The mercury sample was then cooled in liquid helium to study the linear dependence of resistance on temperature. It was observed that, as the temperature decreased, the...
