Phase diagrams of multi-component systems are critical for the development and engineering of material alloys for all technological applications. At nano dimensions, surfaces (and interfaces) play a significant role in changing equilibrium thermodynamics and phase stability. In this work, it is shown that these surfaces at small dimensions affect the relative equilibrium thermodynamics of the d...

Nanospray desorption electrospray ionization (nano-DESI) combined with high-resolution mass spectrometry (HR-MS) is a promising approach for the detailed, molecular-level chemical characterization of atmospheric organic aerosols (OA) collected in laboratory and field experiments. The nano-DESI technique possesses distinct advantages of technical simplicity, enhanced sensitivity, and signal stab...

calcium carbonate nano-particles were synthesized by a reverse micro-emulsion method at room temperature with tween® 80 and span® 80 as co-surfactants. the nano-particles synthesized were surface modified by stearic acid. an important operating variable in the span 80-tween 80/toluene/water reverse micro-emulsion system, the ω-value (water/surfactant molar ratio) was investigated. the material ...

In this work, we investigate the effect of broadband antireflection of a medium by a layer of embedded nano-cavities arranged near the surface. It is shown that this structure is versatile and allows near 100% transmittance in a wide spectral range practically for any dielectric material. The approximate model of nano-structured layer is suggested that allows to determine the parameters of the ...

A microlens array made of polymer/nanosized polymer-dispersed liquid crystal (nano-PDLC) is demonstrated. The polymer was first patterned into microlens array cavities on a planar substrate and the molded polymer cavities were filled with nano-PDLC material. The nano-PDLC-based microlens is optically transparent. The focal length of the microlens is electrically tunable and the response time is...
