Plasma sprayed bioactive glass coatings were studied using crushed 45S5 powder. It is widely accepted that plasma coating microstructure highly affected by the characteristics of powder and parameters set on spraying process. Once deposition was optimized, two strategies carried out to analyse their effect adhesion: cooling with carbon dioxide while a post heat treatment as-sprayed coatings. Sc...

Plasma-sprayed 45S5 bioactive glass coatings were manufactured using two types of powder feedstocks (commercial and lab-made glass) plasma torches (single triple cathode) to analyse their influence on the microstructure bioactivity coatings. Besides, volatilisation oxides such as Na2O P2O5 during deposition was studied. All microstructurally characterised by scanning electron microscopy, X-ray ...

Each plant production system must foster the availability of oxygen to the plant roots. This includes every plant production system, ranging from the garden or agricultural field outside to the commercial and hobby hydroponics system in the greenhouse. In successful production systems, this happens. It may be due to a favorable air/water relationship in the media or a media component. It may be...

Suspension plasma spraying is a process that enables the production of finely grained nanometric or submicrometric coatings. The suspensions are formulated with the use of fine powder particles in water or alcohol with some additives. Subsequently, the suspension is injected into plasma jet and the liquid additives evaporate. The remaining fine solids are molten and subsequently agglomerate or ...

Abstract Microwave absorbing layer materials (MALMs) are extremely important for many components in fusion reactors to absorb microwave radiation a controlled manner and with predictable power density. Therefore, detailed knowledge of absorption properties absorber coating used is necessary. Plasma-sprayed mixed oxide coatings most commonly those applications where moderate density expected. In...

In the present paper, using a cathodic pin-to-solution electrical discharge electrolysis setup, interaction of the atmospheric air plasma with aqueous solution of copper nitrate and its possibility for synthesis of nano-materials is investigated. An AC (50 Hz) high-voltage power supply (5 kV) with rectified current is used for electrical discharge of the air between a metal pin and the solution...

Atmospheric plasma spraying (APS) is a well established process for preparing ceramic coatings. In this process, powder particles injected into the plasma jet are heated and accelerated simultaneously in the plasma stream and are deposited in molten or semi-molten droplets conditions onto a prepared substrate. During droplet impingement, these molten droplets rapidly solidify to form single spl...

After segmental liver resection, a fibrin glue aerosol was used to stop diffuse bleeding from the liver resection site. Immediately after pressurized administration, severe hypotension and bradycardia occurred, requiring cardiopulmonary resuscitation and inotropic support. Transoesophageal echocardiography demonstrated air in both ventricles deriving from the inferior vena cava; contractility o...
