In the light of climate change and environmental challenges such as a nitrogen crisis, a decreasing biodiversity and waterlogging, the Dutch government is trying to build 900 000 homes by 2030 while aiming for a reduction of 55% of CO2 in the construction industry. Biobased topping-up of existing tenement flats is proposed as a solution to...

To combat global warming, it is crucial to eliminate CO2 emissions by 2050, especially since a third of global emissions are attributed to the building and construction industry. This sector's carbon footprint comprises operational emissions from daily activities and embodied carbon throughout a building's lifecycle. However, as buildings become...

Through molecular dynamics simulations, we demonstrate the possibility of internal resonances in single-walled carbon nanotubes. The resonant condition is engineered with a lack of symmetry in the boundary condition and activated by increasing the energy exchange with a coupled thermal bath. The critical temperature threshold for initiating...

A major global marine transgression occurred during the Callovian to Early Kimmeridgian, which was interrupted locally by a hiatus during the Late Callovian to Early Oxfordian. The transgression may have been a major driver for extensive coral buildup development in the Oxfordian. The depositional hiatus may be related to a combination of...

The configuration of the urban built environment is critical for promoting sustainability and achieving carbon neutrality. However, existing studies mostly use linear and spatial econometric models to investigate the relationship between urban built environments and traffic carbon dioxide (CO<sub>2</sub>) emissions, in-depth studies exploring...

The gas dynamics of single-phase nonreacting fluids whose thermodynamic states are close to vapor-liquid saturation, close to the vapor-liquid critical point, or in supercritical conditions differs quantitatively and qualitatively from the textbook gas dynamics of dilute, ideal gases. Due to nonideal fluid thermodynamic properties,...

Organic micropollutants (OMPs) enter the aquatic environment via municipal wastewater treatment plants (WWTPs). As conventional WWTPs have limited capacity for the removal of OMPs, additional processes are required, like ozone - granular activated carbon (GAC) filtration. A specific lay-out of this process is the O3-STEP® process, in which the...

(Bio)fouling is the most common problem in membrane processes used in water production. It is also a reported unavoidable problem, with mitigation strategies being frequently ineffective in addressing this problem. An ultrapure water plant (UPW) in Emmen (The Netherlands), fed with secondary effluent, comprises the following subsequent...

Carbon dioxide capture and reduction (CCR) process emerges as an efficient catalytic strategy for CO<sub>2</sub> capture and conversion to valuable chemicals. K-promoted Cu/Al<sub>2</sub>O<sub>3</sub> catalysts exhibited promising CO<sub>2</sub> capture efficiency and highly selective conversion to syngas (CO + H<sub>2</sub>). The dynamic...

Carbonated water flooding (CWI) increases oil production due to favorable dissolution effects and viscosity reduction. Accurate modeling of CWI performance requires a simulator with the ability to capture the true physics of such process. In this study, compositional modeling coupled with surface complexation modeling (SCM) are done, allowing...

The increasing greenhouse gas (CO2) emissions constitute one of the most significant global environmental issues. CO2 emissions from buildings and transportation are responsible for the largest proportion of total global carbon emissions from various sectors. Therefore it is necessary to utilize clean energy sources (e.g., renewable energy,...
