We have developed a supersonic pulsed plasma jet device capable of long-distance and high-speed processing, investigated its basic characteristics for surface treatment applications, mainly in the material medical fields. The apparatus is equipped with mechanism to transport active species object be treated by jetting generated high-density outward pulse jets, which allows gas flow velocity inc...

Abstract The article investigates a layer of felt in complex material, which we intend as rehabilitation footwear element. material consists layers rubber and felt, connected with polyurethane adhesive, design it for the manufacture shoe-product sole. inside is contact foot serves an insole. was treated low-temperature plasma (LTP) from material. It experimentally obtained wettability index: co...

NON-THERMAL ATMOSPHERIC-PRESSURE PLASMA FOR STERILIZATION OF SURFACES AND BIOFILMS Johanna Ursula Neuber Old Dominion University, 2016 Director: Dr.Chunqi Jiang Bacterial resistance to antimicrobial methods is a critical issue in many fields of medicine. This work describes the studies performed to characterize and optimize the bacterial inactivation effects of a non-thermal atmospheric-pressur...

BACKGROUND Recently, non-thermal atmospheric pressure plasma sources have been used for biomedical applications such as sterilization, cancer treatment, blood coagulation, and wound healing. Gold nanoparticles (gNPs) have unique optical properties and are useful for biomedical applications. Although low-temperature plasma has been shown to be effective in killing oral bacteria on agar plates, i...

The article is devoted to the compressive review of defects observed in products machinery usage made mainly anti-corrosion steels martensite-austenite group, difficult process materials such as pure titanium, nickel, and their alloys, super high entropy alloys triple fusions produced by laser additive manufacturing, particularly powder bed fusion. Studies were conducted on structural improve q...

Biomaterial surface modification is an efficient method to improve and control blood component-material interactions. In the present study, two different methods (ArF excimer laser irradiation and radio-frequency (RF) plasma treatment) were applied in separate procedures to create a vast range of physicochemical characteristics on the surface of polystyrene (PS) and investigate their effects on...
