Conditions of double-stranded DNA precipitation by the polyamines spermidine and spermine have been determined experimentally and compared to theoretical predictions. The influence of the concentrations of DNA and added monovalent salt, and of the DNA length has been investigated in a systematic manner. Three regimes of DNA concentrations are observed. We clarify the dependence of these regimes...

Collecting exhaled particles that represent small droplets of the alveolar lining fluid shows great promise as a tool for pulmonary surfactant (PS) sampling. In this work we present setup consisting two modules, namely, module droplet collecting, called an electrostatic aerosol trapping (ESAT) system, and measurement studying PS properties. We also suggest method to extract numerical values fro...

The growing increase in emissions of ultrafine particles or nanoparticles by industries and urban centers has become worrisome due to the potential adverse health effects when inhaled. Particles this size range have greater ease pulmonary penetration, being able access bloodstream deposit other regions body. Thus, development optimization equipment processes aimed at removal aerosols been gaini...

Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...

Pilot plant tests on a 220 ton-per-day continuous feed municipal incinerator demonstrates the technical feasibility of electrostatic precipitation for control of stack emission. Data on the nature of the furnace stack gases and the physical characteristics of the dust as well as performance of a pilot unit treating ap­ proximately 600 cfm are presented. Part I Trends in Refuse Disposal by Incin...

Background: Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a therapy option for patients with peritoneal metastases. During PIPAC, high-pressure injector delivers the drugs through nebulizer into cavity. However, gravity typically causes inhomogeneous droplet distribution in space and may be overcome by addition of an electrostatic force, resulting precipitation PIPAC (ePIPAC). Our...
