Surface Modification of Metallic Targets with Ultrashort Laser Pulses
(Acta Physica Polonica. Series A: General Physics, Physics of Condensed Matter, Optics and Quantum Electronics, Atomic and Molecular Physics, Applied Physics, 2009)
Interaction of pulsed femtosecond Ti:sapphire laser (160 fs), operating at high repetition rate (75 MHz) at 800 nm, with nickel-based superalloy Inconel 600 and tungsten-titanium (WTi) target was studied. The WTi target ...
Adsorption of Tiron onto alumina
(Materials Science Forum, 2005)
It has been shown recently that small organic molecules, used as dispersants in the colloidal processing of ceramic powders to adjust the forces between the particles, are quite efficient in preparing aqueous suspensions ...
The model law for SF6 insulated systems
(IEEE Transactions on Plasma Science, 2004)
The variation of probability of the electrical breakdown of gases as a result of varying the interelectrode gap value is considered. The relevant analytical expressions have been obtained by treating the electrical discharge ...
D*(sJ)(2317), D*(J)(2308) and D*(sJ)(2632) as candidates for open-charm tetraquarks
(International Journal of Modern Physics A, 2006)
We review the theoretical and experimental evidence for the candidacy of the D*(sJ)(2317)(+), D*(J)(2308) and the D*(sJ)(2632)(+) for charmed tetraquarks. We briefly review the t Hooft interactions influence on the ...
Influence of the Goos-Hanchen Shift on Tunneling Times in Dispersive Nonlinear Media
(Acta Physica Polonica. Series A: General Physics, Physics of Condensed Matter, Optics and Quantum Electronics, Atomic and Molecular Physics, Applied Physics, 2009)
The Goos-Minchen effect is an optical phenomenon defined as a displacement of the reflected beam of linearly polarized light after the total internal reflection, which occurs perpendicularly to the direction of propagation. ...
Acceleration of high-quality, well-collimated return beam of relativistic electrons by intense laser pulse in a low-density plasma
(Laser and Particle Beams, 2004)
The mechanism of electron acceleration by intense laser pulse interacting with an underdense plasma layer is examined by one-dimensional particle-m-cell (1D-PIC) simulations. The standard dephasing limit and the electron ...
Modeling of nanostructured TiO2 spheres obtained by ultrasonic spray pyrolysis
(Colloids and Surfaces. A: Physicochemical and Engineering Aspects, 2004)
Theoretical model given in our former references [V. Jokanovic, Dj. Janackovic, A.M. Spasic, D. Uskokovic, Mater. Trans., JIM 37 (1996) 627: V. Jokanovic. Dj. Janackovic, D. Uskokovic, Ultrason. Sonochem. 6 (1999) 157; V. ...
Point of zero charge and isoelectric point of alumina
(Materials and Manufacturing Processes, 2008)
The point of zero charge, pHpzc, and the isoelectric point, pHiep, of a commercial alumina sample was investigated in KNO3 solutions. The influence of the concentration and the initial pH value of KNO3 solution used for ...
Extraction of parameters from I-V data for nonideal photodetectors: A comparative study
(Materials Science Forum, 2005)
Parameters that characterize semiconductor devices are often determined with difficulty, and their values very frequently depend on the method used for measurements and analysis. The extraction of diode parameters from the ...
Doughnuts with a LT 110 GT very thin Si crystal
(Journal of Electron Spectroscopy and Related Phenomena, 2003)
This study is devoted to the angular distributions and transmission patterns of 10 MeV protons channeled in a tilted LT 110 GT very thin Si crystal of thickness 100 nm. The tilt angle of the crystal is varied from zero up ...
