STUDIES ON 6-NYLON FIBERS IRRADIATED BY GAMMA-RAY

A Study on the Kinetic and Thermodynamic Parameters of Different Acid Dyes on Nylon 6 Fibers

Electron Spin Resonance (ESR) studies on radical scavenging activity of gamma ray irradiated pepper

The properties of radicals induced in the gamma ray irradiated pepper were investigated by means of spin trapping method and CW-ESR spectroscopy. Three radicals were found in the specimens irrespective of irradiation. The representative ESR spectrum of pepper is composed of a sextet centered at g = 2.0, a singlet at the same g-value, and a singlet at g = 4.0. The first signal is attributable to...

Determination of Protein Content in Gamma (γ)-ray Irradiated and Non-irradiated Natural Rubber Latex Film

With the recent increase and awareness of natural rubber latex protein allergies, it is very important for all health care workers to understand and recognize the need to decrease and/or eliminate latex exposure in the rubber gloves and other rubber products for those individuals who are allergic to natural rubber latex. This study is based on a series of Lowry method of protein analysis. The f...

Modification of Nylon 6 , 6 1

Nylon 6, 6 is regarded as tough and ductile materials since it exhibit high tensile elongation to break and high drop weight impact strengths. However, under conditions of stress concentration such as in the presence of sharp notches or cracks, polyamides exhibit brittle failure. This property, evaluated as notched Izod or Charpy impact tests, indicates that unmodified polyamides exhibit relati...

Damage studies on irradiated tungsten by helium and argon ions in a plasma focus device

Damage of tungsten due to helium and argon ions of a PF device was studied. Tungsten samples were irradiated by 20 shots of the plasma focus device with argon and helium as working gases, separately. The tungsten surface was analyzed by SEM, before and after irradiation. SEM revealed dense blisters with diameters of a few hundred nanometers, on the samples which were irradiated by helium ions, ...
