Impact of forest fire ash on surface charge characteristics of andisols
(LIPPINCOTT WILLIAMS & WILKINS, 2007)
Forest fires are a common occurrence in central southern Chile where soils are mostly Andisols. The ash deposits may alter the chemical properties of the soils in the burned areas and nearby agricultural lands. In a column ...
Capacitance and resistance measurements of SnO2 thick-films
(Springer, 2008-02-05)
Impedance spectroscopy measurements on SnO2 thick films were carried out in an air atmosphere and for temperatures between 25 0C and 425 0C. Capacitance and resistance analyses reveal the mechanisms responsible for ...
Calibration of frequency domain reflectometry sensors to estimate soil moisture in a Geric Xanthic Ferralsol
(Univ Centroccidential Lisandro Alvarado, 2020-01-01)
The use of irrigation is essential to increase crop productivity; however, for efficient water management, it is necessary to more accurately estimate soil moisture. For this reason, the objective in this work was to ...
A polaronic stacking fault defect model for CaCu3Ti4O12 material: an approach for the origin of the huge dielectric constant and semiconducting coexistent features
(Iop Publishing Ltd, 2009-03-07)
This paper proposes a polaronic stacking fault defect model as the origin of the huge dielectric properties in CaCu3Ti4O12 (CCTO) materials. The model reconciles the opposing views of researchers on both sides of the ...
