The arrival of the European and National laws* concerning the official labelling of building materials (CE marking) and the respect of concentration values for some compounds regulations in public buildings as for instance schools, the emergence of the Environmental Assessments of buildings (Breeam, HQE,…) beside the energy performance, as well as the awareness increase of the impact of indoor air quality on the wellness and health (ie ENVIE and Healthvent projects [1]) lead inevitably to the development of new sensing technologies related to the IAQ evaluation. Among the numerous existing measurement devices, electrochemical cells, NDIR and PID ones are the most encountered sensors on the market. The major uses are real time monitoring (CO2) and “friendly” handheld devices. Other applications are also studied in several research labs. Few years ago, the ULg research team investigated the interest of MOS chemical sensors arrays for IAQ evaluation. This presentation aims to review some of the results of those projects. A first is the fast and simple diagnosis of moulds on building materials. The identification of contaminated materials among uncontaminated ones was successful [2-4]. However, the low concentration of the MVOC markers compounds (below 10 µg/m³) and the complexity of the background (material emissions, and VOC content of the indoor air) curbed the use of MOS sensors. Specific preconcentrations have to be developed to improve the diagnosis. Nowadays, with the emergence of new sensing materials and new measurement principles (eg IMS-ion mobility spectrometry [5]), perspectives are again opened. Another project (HEMICPD, Belgian project “Horizontal evaluation method for the implementation of the Construction Products Directive”-Emissions to indoor air [6]) concerned the marking of building materials and one of the tasks was to test the sensors array principle to monitor the compounds emanation from different building material, during 28 days, in emission test chambers. Another goal was to investigate a classification of the materials including their odour level. The results on the use of sensors to evaluate the efficiency of “masking” products pulverised in wallpapers and to manage their use are also explained. [less ▲]

In the context of environmental issues that become more and more prevalent in our society, there has been recently an increase of interest for thermoelectric (TE) materials, which have the property to convert heat into electricity, and vice-versa. Although they do not display exceptional thermopower (in comparison to best thermoelectric like bismuth telluride), oxide materials have attracted some attention for high-temperature TE applications, due to their high stability. Amongst them, CoO2-layered compounds were proposed as good p-type TE candidates. Still, these compounds have been only poorly characterized both theoretically and experimentally. In this work we report a first-principles study of misfit calcium cobaltite (Ca2CoO3)(CoO2)1.618 based on density functional theory and an hybrid functional. The computed structural, electronic and magnetic properties match well the avalaible experimental data. Then the thermoelectric properties can be deduced using the Boltzmann transport formalism within the constant relaxation time approximation and will be discussed. [less ▲]

Agricultural practices have a strong impact on soil bacteria and fungi. Furthermore, microbial community composition can change with the stage of plant development. We are interested in exploring these effects in relation to changes induced by agriculture and plant stage in soil conditions. Some bacteria are influenced only by the plant stage, which induces changes in soil humidity, pH, nitrates, and carbon. We would thus expect these bacteria to be highly sensitive to these parameters. Other bacteria are affected only by the tillage practice applied. Further study is needed to identify the soil parameters responsible for this effect. The plant stage also has a great impact on fungal community composition. [less ▲]

Bibliometrics is a growing research field with the main aim of collecting bibliometric information (citations, publications, awards...) to infer valuable rankings or to predict future academic performance. However, most bibliometric approaches are based either on pairwise comparisons of "objects" (authors, funding applications, academics...) with respect to selected "criteria" (publications, citation rate, h-index...), or on modeling observable academic outcomes using observed such criteria. The purpose of this talk is twofold. First, an improvement of the pairwise comparison approach will be outlined on the basis of so-called multicriteria decision aid (MCDA) routines, which will imply an increased flexibility and added freedom for the decision process. Second, we will start a deeper reflexion on possible connections between bibliometrics and psychometrics. Among others, the possibility of modeling latent "academic ability" as outcome of interest, given manifest criteria, will be put to an open discussion and exchange with the listeners [less ▲]
