Abstract Low-temperature plasma jets at atmospheric pressure generated by sinusoidal and positive pulsed voltages interact differently with the treated surface. In experiment in numerical simulations, we compare operating modes of helium for these types voltages. The discharge current on surface over time heating are studied different parameters acceptable anticancer therapy. intensity emission...

A rapid atmospheric-pressure pulsed helium/hydrogen plasma jet method for conversion of TiO 2 films into defective, black is demonstrated.

The jet of the radio galaxy M87 is misaligned, resulting in a Doppler factor δ ∼ 1 for emission of plasma moving parallel to the jet. This makes the observed fast TeV flares on timescales of tv ∼ 5Rg/c harder to understand as emission from the jet. In previous work, we have proposed a jets-in-a-jet model for the ultra-fast TeV flares with tv ≪ Rg/c seen in Mrk 501 and PKS 2155-304. Here, we sho...
