Summary
Nature creates advanced biominerals like calcium carbonate (CaCO3) by precisely controlling synthesis. This review explores how conditions and additives influence CaCO3 formation, highlighting water's crucial role.
Area of Science:
- Materials Science
- Biomineralization
- Chemistry
Background:
- Nature synthesizes advanced biomineral composites with unique properties through precise control of structure and composition.
- Synthetic biomineral composites lack the same level of control due to incomplete understanding of formation processes.
Purpose of the Study:
- To review the influence of synthesis conditions and additives on calcium carbonate (CaCO3) formation.
- To summarize methods for tuning CaCO3 crystal structure, composition, and properties.
- To emphasize the overlooked role of water in CaCO3 biomineralization.
Main Methods:
- Literature review of CaCO3 formation studies.
- Analysis of synthesis conditions and additives' effects.
- Focus on water's role in mediating CaCO3 crystallization.
Main Results:
- Synthesis conditions and additives significantly impact CaCO3 crystal structure, composition, and properties.
- Various methods exist to tune these parameters during formation.
- Water plays a critical, often underestimated, role in mediating CaCO3 formation and properties.
Conclusions:
- A deeper understanding of synthesis-structure-property relationships is needed for advanced synthetic biominerals.
- Controlling CaCO3 formation requires careful consideration of environmental factors, especially water.
- Further research into water's mediating role can unlock new possibilities in biomimetic materials.

01:20Aldehydes and Ketones with Water: Hydrate Formation
4.7K
An oxygen-based nucleophile, like water, can undergo addition reactions with aldehydes and ketones. The reaction leads to the formation of hydrates, also referred to as 1,1-diols or geminal diols.
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...

01:23States of Water
56.5K
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...

02:16Solution Formation
37.0K
There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride.

01:22Bioavailability: Influencing Factors
354
Bioavailability refers to the extent and rate at which a drug reaches systemic circulation in its active form. Extent refers to the amount of the drug that makes it into circulation, while rate is the speed at which it enters circulation. It is influenced by several factors critical for optimizing drug formulations, dosing regimens, and therapeutic outcomes.Physicochemical properties of drugs and formulationsThe solubility, stability, and dissolution rate of a drug significantly impact its...

01:29The Influence of Affect on Cognition
273
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

01:29The Influence of Cognition on Affect
196
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...
