TiO2 films on CoFe2O4 nanoparticles for the photocatalytic oxidation of rhodamine B: Influence of the alcoholic solutions
In the present work, photocatalytic oxidation of Rhodamine B solutions were performed using a composite material prepared by titanium dioxide films deposited onto cobalt ferrite nanoparticles. Cobalt ferrite nanoparticles ...
Adsorption of antipyrine by activated carbons from FeCl3-activation of Tara gum
(Elsevier BV, 2018)
Activated carbons were synthesized by FeCl3-activation of Tara gum at different temperatures (400–1000 °C). The activating agent and the precursor were physically mixed at different ratios (r= FeCl3:precursor, 0.5–3.0 ...
Electrochemical synthesis of ferrate(Vi): Optimization of parameters and evaluation of their impact in production cost
(Desalination Publications, 2018)
Ferrates have attracted considerable research in the last few decades because their activity is not associated with toxic by products. This research investigated the effect of three factors on ferrate (VI) synthesis using ...
Study of the mechanical and energetic properties of pellets produce from agricultural biomass of quinoa, beans, oat, cattail and wheat
The lack of conventional fuels in rural areas in Peru drives people to burn agricultural wastes that are used as fuel. Burning these wastes produce a large amount of gaseous pollutants that harm the health of ...
Preliminary overview and evaluation of a stepped solar distiller with internal reflective walls and borosilicate vacuum tubes
(Elsevier BV, 2017)
The present study demonstrates that the current use of stepped solar distillers can be enhanced to increase seawater desalination. To this end, we designed a stepped solar still with internal reflective walls and attached ...
Factors affecting the success of women’s entrepreneurship: a review of literature
(Emerald Group Publishing Ltd., 2017)
Women entrepreneurship has grown significantly all over the world, and it is widely established that entrepreneurship is important for economic growth and wealth. Despite those facts, women’s participation in entrepreneurship ...
Comparison between solar distillers with and without solar concentrator
(Allerton Press, Inc., 2016)
In order to desalinate sea water by only solar energy using they were designed and built three distillers in which experimental measurements were taken to calculate production, performance and cost. Distillers by solar ...
In vitro antiproliferative activity of palladium(II) thiosemicarbazone complexes and the corresponding functionalized chitosan coated magnetite nanoparticles
