Correlation between monolayer water structures and dynamics: A two-stage phase transition in terahertz electric fields
Correlation between the structural characteristics and kinetic performance of nanoscale confined water underpins a variety of emerging technologies, ranging from blue energy harvesting to membrane-based separation technologies. In this research, a comprehensive range of molecular dynamics investigations are used to elucidate a precise correlation between the structural configurations and kinetic responses of single-layer water under the influence of terahertz electric field. Under a weak electric field, the monolayer water sustains a stable, ice-like structure across a range of field frequencies, exhibiting a total absence of water flow; however, at strong field strengths, the monolayer water undergoes a remarkable two-stage phase transition in response to variations in field frequency, transitioning sequentially from ice to vapor, and then from vapor to liquid. Consequently, the water flow displays a pronounced peak behavior, intricately dependent on the frequency. These insights open up extensive prospects for the design of novel nanofluidic devices.
期刊介绍:
International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
