Identification of Rhizoctonia solani AG 1-IB in lettuce, AG 4 HG-I in tomato and melon, and AG 4 HG-III in broccoli and spinach, in Brazil
(Kluwer Academic Publ, 2003-05-01)
Fungi isolated in Brazil, from lettuce, broccoli, spinach, melon and tomato, were identified as Rhizoctonia solani. All lettuce isolates anastomosed with both AG 1-IA and IB subgroups and all isolates from broccoli, spinach, ...
Effect of metallic Ag growth on the electrical resistance of 3D flower-like Ag4V2O7 crystals
(2017-06-01)
In this communication, we report for the first time the nucleation and growth of metallic Ag nanoparticles on the surface of 3D flower-like Ag4V2O7 crystals, induced by accelerated electron beam irradiation. The growth of ...
Silver ion release from electrodes of nanotubes of TiO2 impregnated with Ag nanoparticles applied in photoelectrocatalytic disinfection
(Elsevier B.V., 2014-03-15)
Self-organized TiO2 nanotubes arrays electrodes were impregnated with 0-16% of Ag nanoparticles (Ti/TiO2-Ag) using different procedures. The electrodes were characterized by X-ray diffraction (XRD), scanning electron ...
Kinetics of Ag-rich precipitates formation in Cu-Al-Ag alloys
(Elsevier B.V., 2004-06-15)
The kinetics of Ag-rich precipitates formation in the Cu-2 wt.% Al alloy with additions of 2, 4, 6, 8, 10 and 12 wt.% Ag was studied using microhardness changes with temperature and time, differential scanning calorimetry ...
