Ion-acoustic cnoidal waves in a quantum plasma
(2014) [Journal article]Nonlinear ion-acoustic cnoidal wave structures are studied in an unmagnetized quantum plasma. Using the reductive perturbation method, a Korteweg-de Vries equation is derived for appropriate boundary conditions and nonlinear ... -
Ion-acoustic envelope modes in a degenerate relativistic electron-ion plasma
(2016) [Journal article]A self-consistent relativistic two-fluid model is proposed for one-dimensional electron-ion plasma dynamics. A multiple scales perturbation technique is employed, leading to an evolution equation for the wave envelope, in ... -
Ion acoustic solitons in dense magnetized plasmas with nonrelativistic degenerate electrons and positrons
(2014) [Journal article]The propagation of electrostatic waves in a densemagnetized electron–positron–ion (EPI) plasma with nonrelativistic and ultrarelativistic degenerate electrons and positrons is investigated. The linear dispersion relation ... -
Ion beam analyses in titanium nitride technology
(1993) [Journal article]TI e technology of hard coatings based on stoichiometric titanium nitride thin films has been inovated since the past few years in order to fulfill the demands for better performance and lower processing cost put by the ... -
Ion beam analysis (IBA) and instrumental neutron activation analysis (INAA) for forensic characterisation of authentic Viagra® and of sildenafil-based illegal products
(2021) [Journal article]Illegal trafficking of pharmaceutical products by criminal organisations is a global threat for public health. Drugs for erectile dysfunction such as phosphodiesterase type 5 inhibitors are the most commonly counterfeited ... -
Ion-beam–plasma interaction effects on electrostatic solitary wave propagation in ultradense relativistic quantum plasmas
(2017) [Journal article]Understanding the transport properties of charged particle beams is important not only from a fundamental point of view but also due to its relevance in a variety of applications. A theoretical model is established in this ... -
Ion-beam/plasma modes in ultradense relativistic quantum plasmas : dispersion characteristics and beam-driven instability
(2017) [Journal article]A relativistic quantum-hydrodynamic plasma model is proposed, to model the propagation of electrostatic waves in an ultradense quantum electron-ion plasma in the presence of an ion beam. A dispersion relation is derived ... -
Ion beam synthesis of cubic FeSi2
(1993) [Journal article]Cubic FeSi, precipitates were synthesized in Si ( 100) by room-temperature Fe ion implantation followed by Si 500 keV ion beam induced epitaxial crystallization at 320 “C!. High resolution electron microscopy and Rutherford ... -
Ion beam synthesis of cubic-SiC layer on Si(111) substrate
(2006) [Journal article]We have investigated SiC layers produced by ion beam synthesis on Si (111) substrates using different procedures. Bare Si (111) and SiO2/Si (111) structures were implanted with carbon at 40 keV up to a fluence of 4 1017 ... -
Ion-cyclotron instability in plasmas described by product-bi-kappa distributions
(2015) [Journal article]The dispersion relation for parallel propagating waves in the ion-cyclotron branch is investigated numerically by considering that the velocity distribution of the ion population is a function of type product-bi-kappa. We ... -
