1. Reduced Graphene Oxide/Ruthenium Oxide Hexacyanoferrate Nanocomposite for Electrochemical Determination of Ethanol in Commercial Samples
Reduced graphene oxide/ruthenium oxide hexacyanoferrate (rGO/RuOHCF) modified electrode showed synergic activity between the materials attested by the increase of electrochemical current and stability. The preparation of the nanocomposite was made by a simple two-step electrochemical approach. The material structure was characterized by spectroscopic techniq

4. SPATIAL AUTOCORRELATION OF PHYSICAL ATTRIBUTES OF AN OXISOL
ABSTRACT Studies that seek to identify a smaller number of soil attributes that represent others can generate less expenditure of time and financial resources for monitoring cultivated areas. Thus, this study aimed to analyze the spatial distribution and spatial autocorrelation of physical attributes of an Oxisol (Latossolo Vermelho Amarelo, Brazilian Soil C

5. Omni-Directional Wideband Antenna Array with Solar Cells
Abstract Distributed sensor networks are becoming more and more widespread due to their substantial benefits to our daily lives. These sensors, in most cases, are distributed in nature and even may require mobility. This, in turn, implies omnidirectional collector units to collect the data from various sensors at arbitrary directions. This work summarizes th

6. Properties of Cu-Co Composite Catalysts for Synthesis of Aliphatic Alcohols
Cu-Co-containing cellulose-based carbon composite materials (Cu-Co/Cel) were formed by a matrix isolation method. Using X-ray diffraction (XRD), transmission electron microscopy (TEM), infrared-Fourier spectroscopy (IR-Fourier spectroscopy), and non-isothermal research methods, the physicochemical properties of the composites were established. The catalysts

7. Tumor carcinoide na vesícula biliar em cão
ABSTRACT Carcinoid is a neoplasia that arises from dispersed cells of the neuroendocrine system. This tumor is uncommon in animals, and its occurrence in the gallbladder is rare. A male Basset Hound dog’s corpse was taken to the Univerdade Federal de Minas Gerais to be analyzed by the Veterinary Pathology sector, without a description of its previous histo
