Sun, Y. (author), Chen, B. (author), Zhang, Shizhe (author), Blom, C.B.M. (author), Lukovic, M. (author), Ye, G. (author)With the development of waste recovery techniques, previous research has revealed that coarse fractions of municipal solid waste incineration (MSWI) bottom ash (BA) after proper treatment could be applied in the construction sector, while the fines are seldom recovered in practice and normally landfilled. This study explores the potential...journal article 2024

Rusi, Sergio (author), Di Curzio, Diego (author), Di Giovanni, Alessia (author)The Gran Sasso carbonate aquifer is the largest and most productive in the Apennines. Its hydrogeological structure has been studied since the middle of the last century for the springs’ characterization for drinking purposes and for a motorway tunnel. Meanwhile, its hydrodynamic parametrization is less developed and has been limited to...journal article 2024

Angst, Ueli M. (author), Rossi, Emanuele (author), Boschmann Käthler, Carolina (author), Mannes, David (author), Trtik, Pavel (author), Elsener, Bernhard (author), Zhou, Z. (author), Strobl, Markus (author)The steel–concrete interface (SCI) is known to play a major role in corrosion of steel in concrete, but a fundamental understanding is still lacking. One reason is that concrete’s opacity complicates the study of internal processes. Here, we report on the application of bimodal X-ray and neutron microtomography as in-situ imaging techniques...journal article 2024

Diaz, Vitali (author), Corzo Perez, Gerald A. (author), Van Lanen, Henny A.J. (author), Solomatine, D.P. (author)In its three-dimensional (3-D) characterization, drought is an event whose spatial extent changes over time. Each drought event has an onset and end time, a location, a magnitude, and a spatial trajectory. These characteristics help to analyze and describe how drought develops in space and time (i.e., drought dynamics). Methodologies for 3-D...book chapter 2024
