Cloud condensation nucleus (CCN) experiments were carried out for malonic acid, succinic acid, oxalacetic acid, DL-malic acid, glutaric acid, DL-glutamic acid monohydrate, and adipic acid, using both water and methanol as atomization solvents, at three operating supersaturations (0.11%, 0.21%, and 0.32%) in the Caltech three-column CCN 5 instrument (CCNC3). Predictions of CCN behavior for five ...

The atomization of fuel jets in car or plane engines involves complex process with multiphase motions and turbulent flow regimes in a highly coupled way. The Direct Numerical Simulation (DNS) of interfacial flows is investigated in order to characterize the coupling between turbulent flow structures and interface deformations occurring during atomization of a liquid sheet. An incompressible Gho...

A recently proposed computational protocol is employed to obtain highly accurate atomization energies for the full G2/97 test set, which consists of 148 diverse molecules. This computational protocol is based on the explicitly correlated coupled-cluster method with iterative single and double excitations as well as perturbative triple excitations, using quadruple-ζ basis sets. Corrections for h...

An understanding of the physical mechanisms underlying the atomization process from a spray device can reveal important information leading to more effective device design. A commercial nasal spray device exhibiting low pressure atomization was tested to obtain spray formation, its characteristics, droplet size distribution, and droplet velocity. High speed laser photography combined with an in...

In the present paper we have theoretically predicted the physical parameters viz. coordination number, constraints, glass transition temperature, fraction of floppy modes, number of lone pair electrons, bond energy, cohesive energy, heat of atomization, ionicity, metallicity and mean bond energy for (Se70Ge30)100-xBix (0<x<8) glassy alloys. It has been found that average heat of atomization and...

The components for connecting high-performance liquid chromatography (HPLC) with Fourier-transform infrared spectroscopy (FTIR) were investigated to determine estrogen in the water environment, including heating for atomization, solvent removal, sample deposition, drive control, spectrum collection, chip swap, cleaning and drying. Results showed that when the atomization temperature was increas...

In this work, tungsten coil (W-Coil) devices are used as atomizers for electrothermal atomization atomic absorption spectrometry (ETAAS), electrothermal atomization laser excited atomic fluorescence spectrometry (ETA-LEAFS), and electrothermal vaporization inductively coupled plasma atomic emission spectrometry (ETV-ICP-AES). For most cases in ETAAS and ETA-LEAFS, limits of detection (LODs) usi...
