Thermal Degradation Mechanism of a Thermostable Polyester Stabilized with an Open-Cage Oligomeric Silsesquioxane
(MDPI, 2018)
A polyester composite was prepared through the polymerization of an unsaturated ester
resin with styrene and an open-cage oligomeric silsesquioxane with methacrylate groups. The effect
of the open-cage oligomeric ...
Iron zircon pigment synthesis: Proposal of a mixing index for the raw materials mixtures
(ElsevierSociedad Española de Cerámica y Vidrio, 2017)
Iron zircon coral pigments are very interesting from an industrial point of view because of their high colouring power and their stability at high temperatures. However, the pigment's synthesis is particularly troublesome ...
Effect of secondary thermal treatment on crystallinity of spinel-type Co(Cr, Al)2O4 pigments synthesized by solution combustion route
(Elsevier, 2018-03)
The effect of a post-synthesis thermal treatment on CoCr2−2ΨAl2ΨO4 (0.0 ≤ Ψ ≤ 1.0) ceramic pigments synthesized by Solution Combustion Synthesis (SCS) has been studied. As-synthesized SCS pigments were treated at two ...
Solution combustion synthesis of (Ni,Fe)Cr2O4 pigments: Effect of post-synthesis thermal treatments
(Elsevier, 2017-10-15)
Mixed spinel pigments Ni1− ΨFeΨCr2O4 (0 ≤ Ψ ≤ 1) were synthesized by means of a method known as Solution Combustion Synthesis, using urea as fuel. Effects on mineralogy, microstructure and colouring power of composition ...
Solution combustion synthesis of (Co,Ni)Cr2O4 pigments: Influence of initial solution concentration
(Elsevier, 2017-09)
Initial solution concentration effect was studied on the synthesis of mixed spinels Co1-ΨNiΨCr2O4 (0≤Ψ≤1) obtained by Solution Combustion Synthesis. Fd-3m spinel structure was developed in all range of compositions analysed, ...
Effect of the CuO addition on a Sb-doped SnO2 ceramic electrode applied to the removal of Norfloxacin in chloride media by electro-oxidation
(Elsevier, 2020-06)
Norfloxacin is employed as in veterinary and human medicine against gram-positive and gram-negative bacteria. Due to the ineffective treatment at the wastewater treatment plants it becomes an emergent pollutant. Electro-oxidation ...
Influence of Salts on the Photocatalytic Degradation of Formic Acid in Wastewater
(MDPI, 2022-11)
Conventional wastewater treatment technologies have difficulties in feasibly removing persistent organics. The photocatalytic oxidation of these contaminants offers an economical and environmentally friendly solution. In ...
Electrochemical degradation of norfloxacin using BDD and new Sb-doped SnO2 ceramic anodes in an electrochemical reactor in the presence and absence of a cation-exchange membrane
(Elsevier, 2019)
Electrochemical oxidation of Norfloxacin (NOR) in sodium sulphate media has been
comparatively studied in an undivided and in a divided electrolytic cell both containing
either a boron doped diamond (BDD) or a novel ...
Preparation of chamott es as raw material for low - cost ceramic membranes
(Wiley, 2016)
Low cost ceramic membranes are usually prepared fro
m a mixture of natural raw
materials and some organic porogen agent, as starch
. The fact that the porogen must be
completely eliminated during firing, leaving an ...
Magnetic Photocatalyst for Wastewater Tertiary Treatment at Pilot Plant Scale: Disinfection and Enrofloxacin Abatement
(MDPI, 2021-01)
In this work, we have tested a photocatalytic material consisting of a core of SiO2/Fe3O4
coated with TiO2 (Magnox) for plausible tertiary wastewater treatment. For this, a pilot plant of
45 L equipped with an Ultraviolet ...
