Insights in Molecular Interactions in Bulk Heterojunction Organic Solar Cells by Synthesis of Novel Electron Donor Materials
No full textThe effects of global warming are rapidly becoming more apparent.1 Every decade in the last thirty years has seen an increase in the average temperature on the earth’s surface as compared to the preceding decade (Figure 1). They have each been warmer than any decade since systematic measurements started in 1850. Globally averaged combined land and ocean surface temperature data show an increase between 0.8 and 1.2 °C over the period from 1880 to 2018.

No full textCombinatory approach of methacrylated alginate and acid monomers for concrete applications
No full textPolysaccharides, and especially alginate, can be useful for self-healing of cracks in concrete. Instead of weak electrostatic bonds present within calcium alginate, covalent bonds, by methacrylation of the polysaccharides, will result in mechanically stronger superabsorbent polymers (SAPs). These methacrylated alginate chains as backbone are combined with two acrylic monomers in a varying molar fraction. These SAPs show a moisture uptake capacity up to 110% their own weight at a relative humidity of 95%, with a negligible hysteresis. The swelling capacity increased (up to 246 times its own weight) with a decreasing acrylic acid/2 acrylamido-2-methylpropane sulfonic acid ratio. The SAPs also showed a thermal stability up to 200°C. Interestingly, the SAP composed of alginate and acrylic acid exerted a very limited decrease in compressive strength (up to 7% with addition of 1wt% SAP) rendering this material interesting for the envisaged self-healing application.sponsorship: The authors would like to thank the FWO (Research Foundation Flanders) for project funding (3G019012, Effect of tunable hydro gels on concrete microstructure, moisture properties, sealing and self-healing of cracks). The authors would like to acknowledge the group of Peter Adriaensens and especially Gunter Reekmans for the calculation of the degree of methacrylation of algMOD (Organic and Bio-polymer Chemistry Department, UHasselt).

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
