Influence of the Material Composition on the Environmental Impact of Ceramic Glasses

An exhaustive study of the influence of ceramic glass material composition on the environmental impact has been performed. In order to perform a more accurate calculation of the environmental impact a life cycle assessment (LCA) was implemented using real material composition of ceramic glasses. Employing a sequential X-rays Fluorescence spectrometer, the composition of several ceramic glasses were analyzed, as this information is not published by the manufacturers. The environmental impact results of each ceramic glass were surveyed using EcoInvent v3.4 data, and SimaPro 8.4 software, following ReCiPe Endpoint and Carbon Footprint methodologies. The importance of considering the composition on the LCA is shown, establishing significant differences among the analyzed glasses. Few variations in the quantity of material composition generate high differences on the environmental impact values, demonstrating the high influence of the material composition on the environmental impact. Elements such as tin, lithium, and titanium are the ones that generate the highest contribution on the environmental impact. In contrast, silica sand shows the lowest impact in both methodologies despite it supposes between 58% and 63% of their compositions. Others such as barite and magnesium, together with neodymium emerged in the composition of the studied ceramic glasses as they are considered Critical Raw Materials by the European Union, due to their supply risk and economic importance.

The evolution of the internet led to a shift in the business operations environment, giving rise to a plethora of challenges and opportunities for companies. Social networks have become attractive to companies due to their interactive nature, not only facilitating conversations with consumers, but also increasing the possibility of enhancing the online consumer brand engagement. Additionally, social networks and online brand communities increased consumers’ possibility of developing an active role in companies’ decision-making process, through the creation of user generated content, together with the opinion sharing and directly information exchange with brands and other internet users. The main objective of this research is to ascertain whether the active listening practice can contribute, in some way, to the improvement of the relationship maintained between consumers and brands. The current study suggests the adaptation of the active listening practice on the online field, as an attempt to enhance the communication strategies held by brands. Hence, this research seeks to demonstrate that this practice can improve the consumer-brand relationship through the development of two qualitative studies, as main approach, where the findings extracted in the first study will be used as inputs to the second one.

After a halt of four years, the n_TOF spallation neutron facility at CERN has resumed operation in November 2008 with a new spallation target characterized by an improved safety and engineering design, resulting in a more robust overall performance and efficient cooling. The first measurement during the 2009 run has aimed at the full characterization of the neutron beam. Several detectors, such as calibrated fission chambers, the n\textunderscore TOF Silicon Monitor, a MicroMegas detector with ^(10)B and ^(235)U samples, as well as liquid and solid scintillators have been used in order to characterize the properties of the neutron fluence. The spatial profile of the beam has been studied with a specially designed "X-Y" MicroMegas which provided a 2D image of the beam as a function of neutron energy. Both properties have been compared with simulations performed with the FLUKA code. The characterization of the resolution function is based on results from simulations which have been verified by the study of narrow capture resonances of ^(56)Fe, which were measured as part of a new campaign of (n, γ) measurements on Fe and Ni isotopes.
