We present a method to control the interfacial energy of a liquid metal in an electrolyte via electrochemical deposition (or removal) of a surface oxide layer. This simple method can control the capillary behavior of gallium-based liquid metals by tuning the interfacial energy rapidly, significantly, and reversibly using modest voltages.

OSTSS leads to pooled inflammatory mediators in the tear film, causing symptoms like epiphora and discomfort. Here, we present a case where therapeutic nasolacrimal lavage every 2 months resolved epiphora and itchiness, suggesting its efficacy as a therapeutic intervention for OSTSS. Additionally, we report subjective improvements in symptoms in 3 additional patients.

FAQs
Dissolved reactive species act at the surface during controlled contact, producing effects such as removal of contaminants, etching, conversion-layer formation, or deposition. These reactions alter surface characteristics while limiting changes to the bulk material. The resulting interface can support improved adhesion, wettability, corrosion resistance, wear performance, or coating durability, depending on the treatment chemistry and operating conditions.
These variables control how strongly and how long the formulation interacts with the material. Concentration influences the availability of reactive species, temperature affects the treatment conditions, and exposure time determines the duration of contact. Together, they help govern the extent of cleaning, etching, conversion, or deposition, making process control essential for achieving a consistent surface function.
Liquid surface treatment focuses chemical action at the interface rather than substantially altering the material throughout its volume. This localized approach can add functions such as better wettability, adhesion, corrosion resistance, or wear performance while preserving the underlying bulk material. For engineering design, that distinction allows a surface to be tailored for service conditions without replacing the entire component.
Cleaning can remove unwanted surface material, while etching can modify the surface through controlled chemical interaction. Conversion-layer formation creates a chemically altered surface, and deposition adds material at the interface. These mechanisms can improve the conditions for subsequent coating or bonding by changing surface cleanliness, reactivity, or wettability. The appropriate mechanism depends on the required surface function and material.
Common application approaches include immersion, spraying, and other forms of controlled liquid contact. A procedure must coordinate the selected formulation with variables such as concentration, temperature, and exposure time. After treatment, the important outcome is a surface with the intended preparation or functional property, such as improved adhesion, wettability, corrosion resistance, wear performance, or coating durability.
Selection depends on both the material and the required surface performance. Metals, polymers, and other materials may require different liquid formulations or treatment conditions. Engineers can target cleaning, modification, protection, or preparation, then control the process to obtain properties such as corrosion resistance, improved adhesion, wettability, wear performance, or durable coating behavior without substantially changing the bulk.
The approach supports manufacturing, repair, and surface preparation. In manufacturing, controlled chemistry can establish a functional interface before or during finishing operations. In repair, it can restore or modify surface performance, while preparation steps can improve the behavior of later coatings. Its relevance extends across components made from metals, polymers, and other materials where surface properties govern service performance.
