This paper introduces Interface Equilibrator (IE), a new graphical-user-interface software for simulating the equilibrium shape of fluid–fluid interfaces in wide range wetting and capillarity problems. IE provides an easy-to-use three-dimensional computer-aided-design environment to define problem's geometry (i.e., solid surfaces fluids' volumes), by simply loading opportune triangular meshes, chemistry, selecting value relevant experimental parameters (e.g., Young's contact angle). No other input is required. Then, calculates interface's using novel numerical methodology, presented this paper, that consists energy-minimization Monte Carlo simulation alongside built-in automated methods to, e.g., refine interface mesh according its local curvature polish it. The algorithm based on approach introduced few years ago [Soligno et al., “The fluid-fluid interfaces: Derivation method Young–Laplace equations,” J. Chem. Phys. 141, 244702 (2014)] generalized here handle unconstructed meshes with any topology include also types forces due rotating system or line tension). In addition, several illustrative scientifically interesting results are demonstrate IE's versatility capability addressing broad spectrum research problems, many technological applications, such as microfluidics, fluid management at various length scales, printing, colloids, soldering chip manufacture, etc. Finally, reports numerous validation tests, where known analytic solutions compared verify correctness accuracy calculations.

Surface-active agents (surfactants) release potential energy as they migrate from one of two adjacent fluids onto their fluid–fluid interface, a process that profoundly impacts the system's and entropy householding. The continuum thermodynamics underlying such surfactant-enriched binary-fluid system has not yet been explored comprehensively. In this article, we present mathematical description system, in terms balance laws, equations state, permissible constitutive relations interface conditions, satisfies first second law thermodynamics. conditions are revealed through Coleman–Noll analysis. We characterize equilibrium by defining equivalences study an example system. With our work, aim to provide systematically derived framework combines links various elements existing literature, can serve thermodynamically consistent foundation for (numerical) modeling full systems.

This study demonstrates an ultrasensitive method for surface-enhanced Raman spectroscopy (SERS) based on dispersive liquid–liquid microextraction (DLLME) coupled with droplet evaporation a functionalized omniphobic microfiber membrane. The omniphobicity of the membrane was achieved by fabrication fractal structures using silica nanoparticles and lowering surface energy. approach involves preconcentration analyte in ternary mixture water–oil–ethanol, followed collecting microemulsion droplets porous A supraparticle plasmonic formed from acts as hotspots SERS detection. achieves exceptionally low detection limits 10–6–10–14 M four nonvolatile three volatile analytes significance to food safety environment after oil spill. intensity signals depends partition coefficient water microdroplets, response functional groups chemical structure scattering, wetting properties preparation demonstrated this work may have broad applications pesticides environmental monitoring, pharmaceutical waste, hydrocarbon pollutants.

Self-lubricating coating has sparked significant research interest due to its remarkable tribology performance. However, traditional microcapsules-based self-lubricating still faces challenges in long-term serviceability and poor anti-corrosion In this paper, a novel epoxy resin was proposed based on hierarchical design energy wear theory. Microcapsules (MC) containing Polyalphaolefin (PAO40) encapsulated with Polysulfone (PSF) were prepared via the solvent evaporation approach. Ti3C2Tx MXene (T) high thermal conductivity then incorporated into MC-enhanced (EP) construct EP (T-MC-EP). Compared coating, of T-MC-EP increased by 79.4%. Finite element analysis indicated that T constructed thermally conductive network serving as main heat carrier. Furthermore, rate decreased 91.2%, primarily attributed formation lubricating oil film during friction reduction molecular oxidation fracture caused heat. After 31 days salt spray testing, also exhibited superior This work provides an innovative insight designing offers approach for constructing multifunctional coating.
