SnO 2 ceramics with low electrical resistivity obtained by microwave sintering
(2011-08-01)
The main aim of this study was to develop dense and conducting SnO 2 ceramics without precipitated phases on the grain boundaries, which was verified using field emission scanning microscopy (FE-SEM) coupled with an ...
Textured PbZr0.3Ti0.7O3 thin films produced by polymeric precursor method using microwave oven
(Taylor & Francis Ltd, 2006-01-01)
PbZr0.3Ti0.7O3 (PZT) films were produced by polymeric precursor route and deposited by spin-coater technique on Pt(111)/Ti/SiO2/Si(100) substrates. The films were heat-treated using different furnaces: (a) a conventional ...
Preparation and characterization of a homemade Josephson junction prepared from a thin film sintered in a domestic microwave oven
(2016-03-01)
A homemade Josephson junction was successfully obtained using a superconductor thin film of the BSCCO system. The film was deposited on a lanthanum aluminate, produced from a commercial powder with a nominal composition ...
Adaptações em forno de microondas doméstico para utilização em laboratório
(Sociedade Brasileira de Química, 1997-02-01)
Domestic microwave oven was modified for laboratory applications. Electronic system was made for controlling magnetron irradiation time. Exhaustion and air circulation systems were installed to clean the internal oven ...
Spectrophotometric determination of formaldehyde with chromotropic acid in phosphoric acid medium assisted by microwave oven
(Elsevier B.V., 2004-05-01)
In the present study. a spectrophotometric method for the determination of formaldehyde by using chromotropic acid was devised. in which the use of potentially hazardous and corrosive concentrated sulfuric acid was eliminated ...
Synthesis and characterization of CaBi4Ti4O15 thin films annealed by microwave and conventional furnaces
(Elsevier B.V., 2007-08-01)
CaBi4Ti4O15 thin films were deposited by the polymeric precursor method and crystallized in a domestic microwave oven and conventional furnace. The films obtained for microwave energy are well-adhered, homogeneous and with ...
