The through-hole porous anodic aluminum oxide (AAO) membranes were fabricated by a simple two-step anodization of in 0.3 M oxalic acid, sulfuric and 2 wt.% phosphoric acid solutions under different operating conditions followed the removal remaining Al substrate pore opening/widening process. effect duration second anodizing step on thickness layer influence other such as applied voltage, type electrolyte, purity rate growth discussed detail. opening procedure for all synthesized was...
The invariant-mass spectrum of $e^+ e^-$ pairs produced in $^{12}$C+$^{12}$C collisions at an incident energy 2 GeV per nucleon has been measured for the first time. pair production probabilities span over five orders magnitude from $\pi^0$-Dalitz to $\rho/\omega$ region. Dalitz decays $\pi^0$ and $\eta$ account all yield up 0.15 GeV/c$^2$, but only about 50% above this mass. A comparison with model calculations shows that excess is likely due baryon-resonance vector-meson decays. Transport...
The effect of annealing temperature on crystal structure anodic titanium dioxide (ATO) layers prepared via anodization in the ethylene glycol and glycerol based electrolytes was studied. Then samples were annealed air at temperatures ranging from 400 to 1000 °C. XRD measurements proved that a gradual phase change anatase rutile occurs with increasing temperature. anatase-to-rutile transformation between 500 600 changes average crystallite sizes occurring during heat treatment ATO correlated...
Among various methods of synthesis nanostructured TiO 2 , a self‐organized anodization is the most commonly used and discussed in literature. However, different pretreatment Ti before anodic titanium dioxide (ATO) formation are not often addressed. Therefore, polishing procedures based on mechanical, chemical, electrochemical, combined electrochemical with chemical pretreatments were examined to establish whether they represent effective for smooth surface preparation anodization. The ATO...
Porous anodic alumina membranes with Y-branched and double-branched nanopores were fabricated by the stepwise reduction of anodizing potential during second step anodization carried out in 0.3 M oxalic acid. The process nanoporous layer formation influence parameters on structural features as-obtained aluminum oxide (AAO) discussed detail. pore rearrangement occurring after decrease was investigated basis current density vs. time curves, results correlated field-emission scanning electron...
Porous anodic alumina layers were obtained by a simple two-step anodization of low purity aluminum (99.5 % Al, AA1050 alloy) in 0.3 M oxalic acid electrolyte at 45 V and 20 °C. The effect anode surface area on structural features nanoporous oxide process formation was investigated. An ordered structure composed nanostripes or nanopores formed the Al during electrochemical polishing mixture perchloric ethanol. This nanopattern is then replicated formation. It found that pore diameter,...
Anodic porous alumina layers were fabricated by a two-step self-organized anodization in 0.3 M oxalic acid under various anodizing potentials ranging from 30 to 60 V at two different temperatures (10 and 17 ∘C). The effect of conditions on structural features pore arrangement AAO was investigated detail using the dedicated executable publication combined with ImageJ software. With increasing potential, linear increase average diameter, interpore distance, wall thickness barrier layer...
