Analysis of the Utilization of Air-Cooled Blast Furnace Slag as Industrial Waste Aggregates in Self-Compacting Concrete
(MDPI, 2019-03)
In this work, the effects of replacing the aggregates of self-compacting concrete by air-cooled blast furnace slag have been analysed. Different mixes have been manufactured by substituting the fine and coarse natural ...

Experimental study on partial oxy-combustion technology in a benchscale CO2 capture unit
(Elsevier, 2019-04)
The reduction of CO2 emissions from anthropogenic sources in this century will require a higher reliance on carbon capture and storage (CCS) technologies. Post-combustion based on a regenerative chemical absorption is ...

A five-stage treatment train for water recovery from urine and shower water for long-term human Space missions
(Elsevier B.V., 2020)
Long-term human Space missions will rely on regenerative life support as resupply of water, oxygen and food comes with constraints. The International Space Station (ISS) relies on an evaporation/condensation system to ...

Landfill leachate treatment using combined fish scales based activated carbon and solar advanced oxidation processes
(Elsevier, 2019-03)
The depuration of landfill leachate (LL) was evaluated by solar advanced oxidation processes (AOPs) (photo-Fenton + O3 and photo-Fenton + O2) and adsorption processes, using activated carbon made from fish scales, as either ...
