Plasma source and surface treatment method

A plasma source has an outer surface, interrupted by an aperture for delivering an atmospheric plasma from the outer surface. A transport mechanism transports a substrate in parallel with the outer surface, closely to the outer surface, so that gas from the atmospheric plasma may form a gas bearing between the outer surface the and the substrate...

Fluorocarbon coatings deposited on micron-sized particles by atmospheric PECVD

Fluorocarbon coatings have been deposited on micron-sized silica particles by means of atmospheric pressure plasma-enhanced chemical vapor deposition (PECVD). The silica particles have a diameter in the range between 40 and 70 ?m. They are fluidized at atmospheric pressure in a circulating fluidized bed combined with a dielectric barrier...

SDBD plasma jet for skin disinfection

A consortium consisting of the research institute TNO, the medical university and hospital St Radboud and two industrial enterprises is working on a non-thermal plasma treatment method for skin and wound disinfection. The group is seeking for cooperation, in particular in the field of validation methods and potential standardization for plasma...

Electrospray crystallization for high-quality submicron-sized crystals

Nano- and submicron-sized crystals are too small to contain inclusions and are, therefore, expected to have a higher internal quality compared to conventionally sized particles (several tens to hundreds of microns). Using electrospray crystallization, nano- and submicron-sized crystals can be easily produced. With the aid of electrospray...

Electrospray: A simple technique to create nanosized RDX

The sensitivity of an energetic compound is related to the crystal product quality of that material: internal defects such as inclusions can lead to unwanted initiation. Nano- and submicron sized crystals are too small to contain inclusions and therefore might be less sensitive. With a technique called electrospray crystallization nano- and...

Particle coating – a novel trend in energetic materials engineering

The development of new energetic materials with enhanced blast properties requires better understanding of factors as particle type, size and particle/matrix distribution. The ability of growing a coating on particles opens new possibilities in energetic materials engineering. Functionalities as ingredient compatibility, increased burning rates...

Modification and characterization of (energetic) nanomaterials

Nanomaterials are a topic of increased interest, since they have properties which differ from their macroscopic counterparts. Many applications nowadays take advantage of the new functionalities which natural and manufactured nanoparticles possess. Based on these developments, also the research on energetic nanomaterials is receiving more and...

Energetic materials: Crystallization, characterization and insensitive plastic bonded explosives

The product quality of energetic materials is predominantly determined by the crystallization process applied to produce these materials. It has been demonstrated in the past that the higher the product quality of the solid energetic ingredients, the less sensitive a plastic bonded explosive containing these energetic materials becomes. The...

Synthesis and coating of copper oxide nanoparticles using atmospheric pressure plasma

Metals and metal oxides are well-known catalysts in many applications. TNO investigates metal and metal oxide nanoparticles as catalysts in rocket and gun propellants. Using nanosize particles allows to tune the curing, mechanical or ballistic properties of the propellant, but to avoid undesired chemical side-reactions a coating of these...

Coupled electrical-fluid model of pulsed electric field treatment in a model food system

A coupled electrical-fluid model of a pulsed electric field (PEF) treatment is presented. The modeling of PEF food treatment to date has been limited to a separate study of the electric field distribution and the product flow. A model was developed that couples the electric field and fluid dynamics analysis. The main feature of the model is that...
