The purpose of this study is to evaluate the characteristics ventilation runoff particles. Using CFD analysis, indoor space with single-side opening model filled particles and passive scalar provide differential temperature ventilation. RANS LES analysis methods, as well size number generated in a room, will be changed compare concentration rate trends. are assumed water that do not evaporate. ...

Abstract Cationic and anionic clusters of the group-14 elements carbon, silicon, germanium, tin, lead are produced by high-vacuum laser ablation studied with a multi-reflection time-of-flight mass spectrometer. In-trap photodissociation is performed for cluster species in size range $$n =$$ n =</mml:mo...

The gasification progress which was coupled between heat transfer and fluid-flow on rib-tube of Open Rack Vaporizer (ORV) was studied in this paper. Based on theoretical analysis and experiment, the k ε − model and wall-function were chose to simulate the flow field of rib-tube, and the multiphase flow was described by the mixture model, in which the dispersed phase was defined by different vel...

We report on the use of nucleic acid bases (NBs) in organic light emitting diodes (OLEDs). NBs are small molecules that are the basic building blocks of the larger DNA polymer. NBs readily thermally evaporate and integrate well into the vacuum deposited OLED fabrication. Adenine (A) and thymine (T) were deposited as electron-blocking/hole-transport layers (EBL/HTL) that resulted in increases in...

Using molecular dynamics simulations, we show that the evaporation of nanoscale water on hydrophobic-hydrophilic patterned surfaces is unexpectedly faster than that on any surfaces with uniform wettability. The key to this phenomenon is that, on the patterned surface, the evaporation rate from the hydrophilic region only slightly decreases due to the correspondingly increased water thickness; m...

A erosol particles resulting from human activity such as sulfate and carbonaceous aerosols have substantially increased the global mean aerosol burden since preindustrial times. Aerosol particles can affect the climate system via several mechanisms. The most prominent impacts are 1) the reflection of solar radiation back to space (a "direct" effect), 2) the absorption of solar radiation by soot...

Many models in which the object under study loses all its mass have appeared in the literature. This can be found from evaporating stars to incipient black holes, all the way to evaporating black holes. In this paper we try a semiclassical study of these evaporating models centred on the evaporating event itself. We analyse their common properties, behaviours and possibilities. Specifically, we...

By subjecting DNA aqueous solution to evaporate in a curve-on-flat geometry that was composed of either a spherical lens or a cylindrical lens situated on a flat substrate, a set of highly aligned DNA nanowires in the forms of spokes and parallel stripes over a macroscopic area (i.e., millimeter scale) were successfully created. The DNA molecules were stretched and aligned on polymer-coated sub...

Diblock copolymers are known to spontaneously organize into polymer vesicles. Typically, this is achieved through the techniques of film rehydration or electroformation. We present a new method for generating polymer vesicles from double emulsions. We generate precision water-in-oil-in-water double emulsions from the breakup of concentric fluid streams; the hydrophobic fluid is a volatile mixtu...
