Abstract

Electrospray, essential in nanoparticle synthesis, biomedical diagnostics, and drug delivery, relies on onset field strength, the minimum electric field needed for liquid ejection. Nanoscale electrospray, with nanometer-sized nozzles, offers precise control and efficiency. This study uses molecular dynamics simulations to examine factors affecting onset field strength, such as pore geometry, solution environment, and surface properties. Findings show that surface properties can alter onset field strength by up to 50%, with enhanced hydrophilicity and negative surface charges reducing the required field strength. These insights are crucial for optimizing nanoscale electrospray in various applications.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
