Title: How droplets nucleate and grow on liquids and liquid impregnated surfaces While nucleation is most likely to occur at the liquid–air interface, the liquid viscosity plays a key role in determining the overall growth of droplets. a Condensation on liquids has been studied extensively in context of breath figure templating, materials synthesis and enhancing heat transfer using liquid impre...

This paper examines the role of mathematical idealization in describing and explaining various features of the world. It examines two cases: first, briefly, the modeling of shock formation using the idealization of the continuum. Second, and in more detail, the breaking of droplets from the points of view of both analytic fluid mechanics and molecular dynamical simulations at the nano-level. It...

The properties of nanoparticles and the performance of products made with nano-sized precursors significantly depend on the shape of the particle size distribution (PSD) or more precisely the broadness of the PSD, the modality and of course the specific particle sizes covered by the PSD. Especially the controlled adjustment of particle size is of interest due to the size-dependent physical and ...

One of the great challenges in cellular studies is to develop a rapid and biocompatible analytical tool for single-cell analysis. We report a rapid, DNA nanostructure-supported aptamer pull-down (DNaPull) assay under convective flux in a glass capillary for analyzing the contents of droplets with nano- or picoliter volumes. We have demonstrated that the scaffolded aptamer can greatly improve th...

Turbulent flow of water in a narrow gap of an emulsifier is investigated experimentally using micro-PIV (micro Particle Image Velocimetry) technique and compared with numerical predictions performed using the commercial code Fluent. The purpose of the investigations is to develop a procedure for wellcontrolled generation of mono-disperse suspension of micro droplets. These droplets will form a ...

Nano-patterned substrates offer possibilities for controlling the motion of fluids without external energy supply in novel technologies microfluidics, coatings, etc. Here, we report on rugotaxial droplets wrinkled with gradient wavelength wrinkles by exploring a broad range parameters, such as amplitude wrinkles, substrate wettability, droplet size and gradient. Adopting theoretical molecular d...

The spray flash evaporation process enables to recrystallize organic materials on submicron and nano scale is basically based the sudden depressurization of solution from superheated state primary vacuum through a nozzle. immediate dissolved micro droplets results in release or nanoparticles. As first step, experimental data recrystallization were collected for different energetic by varying su...

This paper reports a novel single-step wafer-level fabrication of superhydrophobic micro/nano dual-scale (MNDS) poly(dimethylsiloxane) (PDMS) films. The MNDS PDMS films were replicated directly from an ultralow-surface-energy silicon substrate at high temperature without any surfactant coating, achieving high precision. An improved deep reactive ion etching (DRIE) process with enhanced passivat...
