Effect of Atomic Number on Plasma Pinch Properties and Radiative Emissions
Published 2021-01-01“…The results showed that the minimum radius of the plasma focus in the case of the hydrogen plasma pinch was 0.30 cm and in the case of the argon plasma pinch 0.17 cm, and this affected the value of the radiation emission as it was 7.8×10−6 J and 11 J for the hydrogen and argon pinch, respectively. The energy of the ion beam released by the breakdown of the plasma pinch was found as En=23.8 J in the state of hydrogen and En=105 J in the state of argon.…”

Evaluation Technique of Chloride Penetration Using Apparent Diffusion Coefficient and Neural Network Algorithm
Published 2014-01-01“…Diffusion coefficient from chloride migration test is currently used; however this cannot provide a conventional solution like total chloride contents since it depicts only ion migration velocity in electrical field. This paper proposes a simple analysis technique for chloride behavior using apparent diffusion coefficient from neural network algorithm with time-dependent diffusion phenomena. …”

Photochemical reactivity of zinc tetraphenylporphyrin induced by nonstoichiometric CdS nanoparticles in 2-propanol
Published 2001-01-01“…The photodecomposition of ZnTPP in 2-propanol, in the presence of CdS(e-CB/h+VB) and molecular oxygen, is linked to isopropyl free radicals formed by both hole transfer from CdS(h+VB) to (CH3)2CHOH and the reaction of superoxide ion (O2−) with 2-propanol. Isopropyl free radicals react with ZnTPP, leading to the formation of ZnTPP•−. …”
