Structure, thermodynamics and dielectric properties of water under nanoscale confinement and search for reversible phase change of methanol in astrochemical conditions
Abstract
This thesis majorly explores the intricate structural, dynamical, and dielectric
characteristics of monolayer water and other organic molecules under
strong confinement and astrochemical condition. Water molecules confined
within hydrophobic nanocavities display anomalous structural and dynamic
behavior. The structural, dynamical, and thermodynamic properties of water
confined within nanopores of diverse geometries are of fundamental importance
due to their potential applications in various nanofluidic devices, such
as ion-selective channels, ionic transistors, sensors, molecular sieves, desalination
systems, and blue energy harvesters. Apart from worldly applications,
confined water studies also hold the potential to understand the ice that exists
in comets, interstellar medium, and in water giants like Neptune. Unlike
terrestrial ice, astrochemical ice shows unique characteristics due to extreme
conditions in space. Confinement serves as a model system to emulate such ice
structures in laboratory conditions. In the list of detected molecules outside
Earth, after water, methanol is the most abundant complex organic molecule.
Methanol serves as a precursor in the formation of several higher-order complex
organic molecules such as glycols and aldehydes, and it mostly exists in
ice form in the interstellar medium. Therefore, in this study, apart from fundamental
studies on confined water, we have also investigated the ice structure
of methanol, which is of significant astrochemical importance
