Luminescent nano-composites generated from a spray
(Elsevier B.V., 2008-11-01)
The spray-pyrolysis (SP) synthesis technique has been employed to obtain SiO2:Eu3+ and gamma-AlOOH:Eu3+, It was possible to obtain sub-micrometric spherical particles of SiO2 with luminescent Eu3+ ions bonded to the silica ...
Nano-modification of Si-wafer surfaces using low-cost ambient air diffuse plasma
(2015-01-01)
In this paper, we demonstrated the cleaning and nano-oxidation of Si-wafer surfaces by atmospheric pressure plasma, generated in ambient air using diffuse coplanar surface barrier discharge. Plasma treatment for one second ...
Use of silica fume and nano-silica in mortars attacked by acids present in pig manure
(2018-01-01)
Pig houses provide a highly aggressive environment to concrete structures. The chemical aggressiveness generated by pig manure may cause wear, loss in strength and premature damage to floors, leading to animal hoof diseases. ...
Effects of adding nano-clay (montmorillonite) on performance of polyvinyl acetate (PVAc) and urea-formaldehyde (UF) adhesives in Carapa guianensis, a tropical species
(Elsevier Ltd, 2015-06)
The aim of this study was to improve the bond strength resistance of polyvinyl acetate (PVAc) and urea-formaldehyde (UF) adhesives modified with nano-clay (montmorillonite) with a tropical species of wood known to exhibit ...

Giant Chemo-Resistance of SnO disk-like structures
(2013-07-03)
Single crystalline SnO micro-disks, synthesized by a carbothermal reduction process, exhibited a nearly 1000-fold increase in resistance upon exposure to 100 ppm of NO2 without addition of catalysts or dopants nor the ...
Estudio de la Toxicidad Sub-crónica de la Nano Plata en Ratas Wistar
(Escuela Superior Politécnica de Chimborazo, 2010-04-29)
The nano silver studies that are being carried out for the benefit of health do not have a scientific support that guarantees the safety in the use of this product in the long term, so the study of sub-chronic toxicity at ...
