Novel green process to modify ABS surface before its metallization: optophysic treatment

Abstract: The preconditioning of an ABS surface prior to metallization was achieved by a new technique, here named “optophysic treatment.” The dry procedure consists of alternating corona discharges and UV. The substrates are metallized by either the electroless or dynamic chemical plating (DCP) method. The surface modification is attributed to capture-release of charges, chemical modification on the surface, and a preferential removing of polybutadiene domains. Corona and UV cause superficial and depth ozonolysis, respectively, which increase oxygen content and propitiate a final hydrophilic surface. Corona acts by stripping more efficiently UV reticulated polymeric chains. Deposits with adhesions that surpass those of conventional electroless are obtained with optophysic treatment and a precoating by DCP.

Electrocatalytic Activity of Three Carbon Materials for the In-situ Production of Hydrogen Peroxide and Its Application to the Electro-Fenton Heterogeneous Process

Abstract: Abstract The in-situ generation of hydrogen peroxide in the electro-Fenton process is paramount. For this reason, in this research the electrocatalytic activity of three carbon materials was evaluated in the reaction of oxygen reduction via two electrons. Furthermore, in order to eliminate the use of iron salts in solution (homogeneous process), the iron was electrodeposited on the surface of the carbon material and was applied in a heterogeneous electro-Fenton process for the degradation of methyl orange dye. The largest amount of generated H2O2 was achieved with the Carbon Felt (CF) electrode (460 mg L−1) without iron after 60 minutes. The electrodes with electrodeposited iron were characterized by SEM and EDS, which showed that the surface of the Carbon Sponge (CS) electrode had the largest amount of iron (23.84 %). However, the CF electrode showed a greater and faster degradation of the dye (98 %) after 30 minutes of treatment. The CF material was the best and most-viable choice of material compared to the CS and Carbon Cloth (CC) for industrial application in electro-Fenton processes, due to its greater catalytic activity in the production of H2O2, uniform distribution of iron, more efficient TOC removal and lower cost per cm2 of material.

Thermal Energy Storage by the Encapsulation of Phase Change Materials in Building Elements-A Review.

Abstract: The energy sector is one of the fields of interest for different nations around the world. Due to the current fossil fuel crisis, the scientific community develops new energy-saving experiences to address this concern. Buildings are one of the elements of higher energy consumption, so the generation of knowledge and technological development may offer solutions to this energy demand, which are more than welcome. Phase change materials (PCMs) included in building elements such as wall panels, blocks, panels or coatings, for heating and cooling applications have been shown, when heating, to increase the heat storage capacity by absorbing heat as latent heat. Therefore, the use of latent heat storage systems using phase change materials (PCMs) has been investigated within the last two decades. In the present review, the macro and micro encapsulation methods for construction materials are reviewed, the former being the most viable method of inclusion of PCMs in construction elements. In addition, based on the analysis of the existing papers on the encapsulation process of PCMs, the importance to pay more attention to the bio-based PCMs is shown, since more research is needed to process such PCMs. To determine its thermophysical and mechanical behavior at the micro and macro levels, in order to see the feasibility of substituting petroleum-based PCMs with a more environmentally friendly bio-based one, a section devoted to the excellent PCM with lightweight aggregate (PCM-LWA concrete) is presented due to the lack of description given in other reviews.
