Production of transparent soda-lime glass from rice husk containing iron and manganese impurities
(2020-12-01)
Glass is a familiar material that requires abundant mineral sources, with devastating consequences for the environment. Rice husk ash (RHA) presents a very high silica content (>95%) and it can be a very promising alternative ...
Effect of organic impurities on the morphology and crystallographic texture of zinc electrodeposits
(Elsevier Science, 2017-05)
This work describes the effect of some organic impurities on the quality of zinc deposits and on the efficiency of the electrowinning process. The presence of some organics (i.e., flotation collectors, flocculant and ...
The GIPAW approach for the study of local structures and the electric field gradients at Cd and Ta impurity sites. Application to doped yttria ceramics
(Elsevier, 2020-01)
We report a first-principles study on the structural properties, the electronic structure and the hyperfine properties of the pure, Cd-, and Ta-doped yttria (Y2O3) using the Gauge-Including Projector Augmented Waves (GIPAW) ...
