 In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...

The therapeutic effects of non-thermal plasma are expected in the medical fields, including hemostasis, vascularization, prevention of organ adhesion, and cell proliferation. Cancer is an internal enemy arising from normal tissue in the body. The prognosis of metastatic and recurrent cancers is still poor despite advances in medicine. To apply non-thermal plasma in cancer treatment is now on go...

Turbulent heating may play an important role in galaxy-cluster plasmas, but if turbulent heating is to balance radiative cooling in a quasi-steady state, some mechanism must regulate the turbulent velocity so that it is neither too large nor too small. This paper explores one possible regulating mechanism associated with an active galactic nucleus at cluster center. A steady-state model for the...

The laser irradiation have shown a range of applications from fabricating, melting, and evaporating nanoparticles to changing their shape, structure, size, and size distribution. Laser induced plasma has used for different diagnostic and technological applications as detection, thin film deposition, and elemental identification. The possible interferences of atomic or molecular species are used...

The use of thermal and non-thermal atmospheric pressure plasma to solve problems related agriculture biomedicine is the focus this paper. Plasma in equilibrium used where heat required. In agriculture, it treat soil land contaminated by products biomass, plastics, post-hospital pharmaceutical waste combustion, also ecological phenomena that have recently been observed, such as droughts, floods ...

Article history: Received 18 March 2016 Revised 16 July 2016 Accepted in revised form 28 July 2016 Available online xxxx Photoluminescence piezospectroscopy (PLPS) was used as a non-destructive technique for the measurement of residual stresses within the thermally grown oxide (TGO) layer beneath plasma-spray thermal barrier coatings (TBC). The technique has proved to be very effective for such...

In recent years plasma-sprayed coatings and polymer coatings have found wide application in manufacturing. Although the quality of the coatings improved over the years, there is a need for reliable NDE techniques to assess the quality and test the integrity of these coatings. Most existing techniques are not suitable for real-time applications. The introduction of synchronous thermal wave video...

INTRODUCTION The use of repeated thermal therapy for improving the symptoms of chronic heart failure (CHF) has been recently demonstrated. Usually, thermal therapy requires an infrared dry sauna. However, it is difficult for small clinics to acquire such an expensive and extensive system. The present study assessed the efficacy of its substitution with hot water bottles. Moreover, there are no ...
