The main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the Qeshm Channel. For this purpose, the curves of the pressure on the Persian Gulf and Oman Sea, during the passing of the atmospheric low pressure system, are extracted across the region. During the time of occurrence of these events, sea level oscillations in the coastal areas of...

Atmospheric pressure plasma jets are well-known in the plasma chemistry community because of their novel applications. However, in spite of a large amount of publications, the physical chemistry of plasma jet/surface interactions is still unknown. In this work, an atmospheric pressure plasma jet (APPJ) in pure argon will be used to modify the surface of PET non-woven textiles. In a first part o...

In this research different types of Al2O3 were used as supports to prepare catalysts for dehydrogenation of isobutane to isobutene. These supports were Al2O3 from Merck, Axen and gamma Al2O3 synthesized from Al(OH)3. Sn/Pt/Al2O3 catalysts were prepared by sequential impregnation, at first Pt and then Sn was deposited. Characterization of catalysts was performed by X-ray powder diffraction (XRD)...

The current work demonstrates the feasibility of atmospheric pressure non-thermal plasma technique for NOx pollution control. Atmospheric pressure dielectric barrier discharge plasma reactor has been constructed for the treatment of the exhaust of 4kWs free load diesel engine. The nature and properties of the discharge were identified through studying electrical characterization of the discharg...

Atmospheric pressure non-equilibrium water vapour plasma technology was developed, tested and partly employed for fuel conversion and production of hydrogen-rich gas. The results of experimental investigation on plasma source characteristics dependent on the anode material and prevailing external factors are presented. The effect of plasma source anode material on the elemental composition of e...

Multiwalled carbon nanotubes (MWCNTs) were treated with an atmospheric pressure plasma source using an argon/water mixture. Optical emission diagnostics has shown that hydroxyl radicals (OH) were the major reactive species in the plasma. The structural changes in MWCNTs were monitored by micro-Raman spectroscopy. The observed variation of the D and G band intensity ratio and position dispersion...

The DNA molecule is observed to be very susceptible to short-term exposures to an atmospheric pressure plasma jet. The DNA damage induced by plasma-generated species, i.e. excited atoms, charged particles, electrons and UV light is determined.

While gas discharges under atmospheric pressure occur as filamentary discharges, most studies on plasma polymerization, or plasma Chemical Vapour Deposition (CVD), were carried out in low-pressure (low temperature, non-equilibrium) plasma. However, it is reasonable to assume that the fundamentals of plasma polymerization found by low-pressure discharge apply to the gas phase in the filamentary ...

Recently, there have been enormous efforts to tailor the properties of graphene. These improved properties extend the prospect of graphene for a broad range of applications. Plasmas find applications in various fields including materials science and have been emerging in the field of nanotechnology. This review focuses on different plasma functionalization processes of graphene and its oxide co...

PURPOSE Autoclaves and UV sterilizers have been commonly used to prevent cross-infections between dental patients and dental instruments or materials contaminated by saliva and blood. To develop a dental sterilizer which can sterilize most materials, such as metals, rubbers, and plastics, the sterilization effect of an atmospheric pressure non-thermal air plasma device was evaluated. MATERIAL...
