Photolysis of water and subsequent escape of hydrogen can give rise to an oxygen atmosphere on Ganymede. Growth of the atmosphere may be limited by escape of fast oxygen atoms formed by photodissociation of 02. Escape of oxygen and hydrogen in an equilibrium configuration should balance net evaporation of water from the satellite's surface and the partial pressure of atmospheric O2 could be as ...

atmospheric pressure plasma (app) is an emerging non thermal technology for the improvement of food  safety. non-thermal plasma (ntp) is a neutral ionized gas that comprises highly reactive spices including, positive ions, negative ions, free radicals, electrons, excited or non excited molecules and photons at or near room temperature. ntp can be generated at atmospheric pressure that makes it ...

The aim of this study was to prepare surfactant free Diclofenac sodium loaded ethyl cellulose nanoparticles by O/W single emulsion solvent evaporation high pressure homogenization technique.In the preparation of O/W single emulsion sodium alginate used as an emulsifying/stabilizing agent. Microparticles of nine different batches at different condition were prepared after that optimized batch wa...

• Transition of aerosol dynamics regime creates distinct droplet evaporation profiles. Properties MOF crystals can be modified by decreasing operating pressure. Gas adsorption data are evaluated for CO 2 enthalpy and selectivity. Dissociation solvent under low pressure increases formation open metal sites. A microdroplet-based spray process has been recently developed the synthesis metal–organi...

A practical aerobic oxidation of indole carbinols using Fe(NO3)3·9H2O/TEMPO/NaCl in DCE at room temperature and atmospheric pressure of oxygen affording aldehydes or ketones in good to excellent yields was developed. Furthermore, when using the industrially favored solvent toluene instead of DCE and air instead of pure oxygen, this protocol also works smoothly, demonstrating its high potential ...

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...

Atmospheric pressure non equilibrium plasma treatments have been implemented to produce solvent-free Poly-L-lactic acid (PLLA) scaffolds, to improve biocompatibility of PLLA mats and to increase electrolyte uptake of Poly(vinylidene fluoride) (PVDF) separators for lithium batteries. It has been observed that plasma treatments are a suitable way to improve polymeric solution electrospinnability,...

In this study, we prepared all-trans retinoic acid (ATRA)-encapsulated, surfactant-free, PLGA nanoparticles. The nanoparticles were formed by nanoprecipitation process, after which the solvent was removed by solvent evaporation or dialysis method. When a nanoparticle was prepared by the nanoprecipitation solvent evaporation method, the nanoparticles were bigger than the nanoparticles of the nan...

This paper considers the stability of thin liquid layers of binary mixtures of a volatile (solvent) species and a non-volatile (polymer) species. Evaporation leads to a depletion of the solvent near the liquid surface. If surface tension increases for lower solvent concentrations, sufficiently strong compositional gradients can lead to Bénard-Marangoni-type convection that is similar to the kin...
