Chemistry in nanoconfined water

Area of Science:

• Chemical Reactions
• Nanotechnology
• Aqueous Chemistry

Background:

• Nanoconfined liquids exhibit unique properties distinct from bulk phases.
• These altered properties significantly influence chemical reactions within nanosolvation environments.
• Understanding these effects is crucial for fields like prebiotic chemistry.

Purpose of the Study:

• To investigate chemical reactions within nanoconfined water lamellae.
• To explore the impact of mineral surface confinement on reaction energetics and mechanisms.
• To assess the relevance to prebiotic peptide formation in aqueous environments.

Main Methods:

• Extensive *ab initio* simulations were performed.
• A wide range of chemical reactions were studied within a nanoconfined water lamella.
• Comparison was made between nanoconfined and bulk water regimes.

Main Results:

• A complex interplay of steric factors and charge-stabilization effects was observed.
• Steric factors typical of confined spaces were identified.
• Charge-stabilization effects in nanoconfined water under extreme conditions were noted, similar to bulk water transitions.

Conclusions:

• Nanoconfinement significantly modifies reaction energetics and mechanisms.
• The findings offer insights into chemical processes in confined aqueous environments.
• This research has implications for understanding early Earth chemistry and peptide synthesis.
