Journal ArticleDOI
TL;DR: In this article, the hydrophobicity and tensile strength of muga silk fiber were investigated using radiofrequency (RF) Ar plasma treatment at various RF powers (10 − 30 W and treatment times (5 − 20 W).

Journal ArticleDOI
TL;DR: In this paper, the authors used a self-compensated emissive probe to evaluate the performance of hexamethyldisiloxane (HDSO) films and their water repellency as a function of DC self bias voltage on the substrates during deposition.

TL;DR: In this article, the results of the explosive field emission cathode plasma expansion velocity and the initial emission area in the planar diode configuration with cathodes made of graphite, stainless steel, polymer velvet, carbon coated, and carbon fiber (needle type) cathodes are presented.
Abstract: The research results of the explosive field emission cathode plasma expansion velocity and the initial emission area in the planar diode configuration with cathodes made of graphite, stainless steel, polymer velvet, carbon coated, and carbon fiber (needle type) cathodes are presented. The experiments have been performed at the electron accelerator LIA-200 (200 kV, 100 ns, and 4 kA). The diode voltage has been varied from 28–225 kV, whereas the current density has been varied from 86–928 A/cm2 with 100 ns pulse duration. The experimentally obtained electron beam diode perveance has been compared with the 1 dimensional Child-Langmuir- law. It was found that initially only a part of the cathode take part in the emission process. The plasma expands at 1.7–5.2 cm/μs for 4 mm anode-cathode gap for various cathode materials. It was found that the plasma expansion velocity increases with the decrease in the cathode diameter. At the beginning of the accelerating pulse, the entire cathode area participates in the e...
