Creation of heterogeneous microstructures in copper using high-pressure torsion to enhance mechanical properties
(Elsevier Science SA, 2019-05)
This paper studies the effects of high-pressure torsion (HPT) at ambient temperature on microstructural evolution and mechanical properties enhancement in pure copper. The aim is to introduce gradient microstructure, with ...
Grain boundary and grain interior conduction in γ′-Bi2MoO6
(Elsevier Science, 2005-07)
Impedance spectroscopy of fine grained (<10 μm) γ′- Bi2MoO6 samples, in the frequency range of 0.1 Hz-250 kHz, relevant to sensor applications, up to 800°C, has been used to characterize grain boundary and grain interior ...
Role of oxygen on the phase stability and microstructure evolution of CaCu3Ti4O12 ceramics
(2017-01-01)
Phase stability and microstructure evolution of polycrystalline CaCu3Ti4O12 (CCTO) ceramics were studied by controlling the partial pressure of oxygen (from a poor to an oxygen rich atmosphere) during the sintering process ...

Pressure effects on nanostructured manganites
(Elsevier Science, 2007-09)
We have measured the pressure sensitivity of magnetic properties on La5 / 8 - y Pry Ca3 / 8 MnO3 (y = 0.3) nanostructured powders. Samples were synthesized following a microwave assisted denitration process and a final ...
Effects of density and sowing pattern on weed suppression and grain yield in three varieties of maize under high weed pressure
We tested the hypothesis that improved weed suppression
by maize can be achieved through increased crop
density and spatial uniformity. Field experiments on
three varieties of maize sown at three densities (5, 7
and ...
Avaliação técnica do sistema operacional de uma unidade armazenadora composta por silos-secadores e a qualidade de grãos de arroz
(Universidade Federal de Santa MariaBrasilUFSMUFSM Cachoeira do Sul, 2020-07-10)
Rice is a crop of prominence for cultivation worldwide, in addition to being essential in the basic diet of human beings. The guarantee of standardization and quality of grains is due to good cultivation and post-harvest ...
