Summary
Water adsorption on carbon materials is complex, influenced by functional groups (FGs) and pore structure. Understanding these interactions is key for industrial applications and fundamental science.
Area of Science:
- Surface Science
- Materials Chemistry
- Physical Chemistry
Background:
- Water adsorption on carbonaceous materials is crucial for industrial processes.
- Understanding molecular interactions, especially with functional groups (FGs) on graphene, is a key research area.
Purpose of the Study:
- To review experimental and theoretical studies on water adsorption on carbonaceous materials.
- To elucidate the relationship between water adsorption, FG concentration, FG topology, and porous carbon structure.
- To propose mechanisms for water adsorption based on adsorbate density.
Main Methods:
- Extensive literature review of experimental and theoretical studies.
- Analysis of water adsorption data in relation to surface functionalization and confinement effects.
Main Results:
- Water adsorption is significantly influenced by the concentration and arrangement of functional groups (FGs).
- The confined space within porous carbons plays a critical role in water adsorption behavior.
- Adsorption mechanisms are proposed based on increasing adsorbate density.
Conclusions:
- The interplay between FGs and confinement dictates unique water adsorption characteristics on carbon materials.
- Water adsorption differs significantly compared to other simple molecules due to these complex interactions.

44.9K
Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.

01:20Porosity and Absorption of Aggregate
833
Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the...

01:57Adaptations that Reduce Water Loss
28.3K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

02:34Water and Mineral Acquisition
35.9K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Solutions of Gases in Liquids
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...

01:14The Carbon Cycle
44.3K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
