Monodisperse aqueous emulsion droplets encapsulating colloidal particles were produced in the oil phase, and controlled microwave irradiation of the aqueous drop phase created spherical colloidal crystals by so-called evaporation-induced self-organization of the colloidal particles. Unlike usual colloidal crystals, colloidal crystals in spherical symmetry (or photonic balls) possessed photonic ...

The variation of moisture during sewage sludge bio-drying was investigated. In situ measurements were conducted to monitor the bulk moisture and water vapor, while the moisture content, water generation, water evaporation and aeration water input of the bio-drying bulk were calculated based on the water mass balance. The moisture in the sewage sludge bio-drying material decreased from 66% to 54...

In this study a new desalination unit is established. It has four cells such as cooling cell, heating cell, evaporation cell and condensation cell. Seawater is pumped into cooling cell to be preheated and then goes to evaporation cell. In the new desalination unit the evaporation and condensation cell is heated and cooled by the heating and cooling cells respectively. The heating of the evapora...

Abstract The evaporation and condensation mechanism of two-phase flow is studied. Euler-Euler pattern used to express the properties flow. research shows that tracking program can accurately track interface. thermal resistance on confluence part insulation becomes larger. working fluids have significant influence two-phase.

Evaporating liquid droplets are omnipresent in nature and technology, such as in inkjet printing, coating, deposition of materials, medical diagnostics, agriculture, the food industry, cosmetics, or spills of liquids. Whereas the evaporation of pure liquids, liquids with dispersed particles, or even liquid mixtures has intensively been studied over the past two decades, the evaporation of terna...

The morphology of solution-cast, phase-separated polymers becomes finer with increasing solvent evaporation rate. We address this observation theoretically for a model polymer where demixing is induced by steady solvent evaporation. In contrast to what is the case for a classical, thermal quench involving immiscible blends, the spinodal instability initially develops slowly and the associated l...

Triangular silver nanoplates, of different orientations, and other nanostructures were successfully synthesized using the Horizontal Vapor Phase Crystal (HVPC) Growth technique for antimicrobial purposes in this study. This finding demonstrates HVPC as an alternative and simple technique to synthesize ordered silver nanomaterials for antimicrobial study. Keyword —alternative method, antimicrobi...

We demonstrate real-time quantitative phase imaging as a new optical approach for measuring the evaporation dynamics of sessile microdroplets. Quantitative phase images of various droplets were captured during evaporation. The images enabled us to generate time-resolved three-dimensional topographic profiles of droplet shape with nanometer accuracy and, without any assumptions about droplet geo...

In December 2001 and 2002 in situ aerosol measurements were made from balloon-borne platforms within polar stratospheric clouds (PSC) which contained particles of supercooled ternary solution (STS), nitric acid trihydrate (NAT) and ice. Particle size (radius >0.15 µm) and number concentrations were measured with two optical particle counters. One of these included an ∼80 cm inlet heated to >244...
