A novel C-Nafton/Fe-ion structured fabric capable of mediating Orange II decomposition in Fenton-immobilized photoassisted reactions is presented. The catalyst preparation requires the right balance between the amount of the Nafion necessary to protect the ...
Aluminum oxidation states in stoichiometric or substoichiometric configuration are studied by core level photoemission spectroscopy on different substrates (SiO2, graphite). They are compared with recent results reported for the interface Si-Al-n+O. Three ...
Collagen type I displays a typical banding periodicity of 67 nm when visualized by atomic force or transmission electron microscopy imaging. We have investigated collagen fibers extracted from rat tail tendons using atomic force microscopy, under different ...
The bacterial inactivation efficiencies of silver metal and oxides and their combinations on textile fabrics was investigated to evaluate the disinfectant action on airborne bacteria. The inactivation performance was seen to depend on the amount of silver ...
Synthesis of adenosine triphosphate (ATP) by the F1F0 ATP synthase involves a membrane-embedded rotary engine, the F-0 domain, which drives the extra-membranous catalytic F-1 domain. The F-0 domain consists of subunits a(1)b(2) and a cylindrical rotor asse ...
Electron cyclotron resonance plasma-assisted molecular-beam epitaxy has been used to grow hexagonal and cubic GaN crystal layers on Si(100). By a combined application of in-situ reflection high-energy electron diffraction, X-ray photoelectron spectroscopy ...
We report the formation of silicon oxide thin films obtained at room temperature by Ar+ bombardment of Si(100) wafers in partial oxygen atmosphere, The ion bombardment was done in the energy range E(b) - 100-1000 eV, with Ar partial pressure P-Ar = 1 x 10( ...
High resolution transmission electron microscopy (HRTEM) and X-ray energy dispersive spectroscopy (EDS) were applied to study the structure of hydroxyapatite (HAP) coatings deposited by plasma spraying on different substrates (Cu, Cr, Ni, NaCl, BaF2). Coat ...
To better characterize a permanent modifier based on iridium deposited on zirconium or tungsten treated platforms of transversely heated graphite atomizer, and to gain addnl. information about its chem. behavior directed to an eventual further optimization ...
A systematic photoelectron spectromicroscopy study is presented of the spatial distribution of a toxic element, aluminium, iron or chromium, in neuron cultures, after exposure to a solution of the element. The study was performed by the X-ray secondary-emi ...
