Techno-economic Assessment of CO₂ Electrolysis: How Interdependencies between Model Variables Propagate Across Different Modeling Scales

The production of base chemicals by electrochemical conversion of captured CO₂ has the potential to close the carbon cycle, thereby contributing to a future energy transition. With the feasibility of low-temperature electrochemical CO₂ conversion demonstrated at lab scale, research is shifting toward optimizing...

Atmospheric pressure atomic layer deposition to increase organic solvent resistance of PDMS

We explore three variants of atomic layer deposition (ALD) to deposit titanium oxide on the soft polymer polydimethylsiloxane (PDMS). We show that the organic solvent resistance of PDMS is increased by two orders of magnitude compared to uncoated PDMS for ALD performed at atmospheric pressure, which results in a unique surface-subsurface...

Electrochemical Reduction of CO₂in Tubular Flow Cells under Gas-Liquid Taylor Flow

Electrochemical reduction of CO₂using renewable energy is a promising avenue for sustainable production of bulk chemicals. However, CO₂electrolysis in aqueous systems is severely limited by mass transfer, leading to low reactor performance insufficient for industrial application. This paper shows that structured reactors...

Revealing how maltodextrin-containing droplets dry using optical coherence tomography

Properties of powders produced from drying solute-containing droplets arise from the dynamic redistribution of solute during drying. While insights on the dynamic redistribution are instrumental for the rational design of powders and for the optimized operation of equipment such as spray dryers, experimental techniques that allow measuring...

Static and dynamic stickiness tests to measure particle stickiness

Sticking of particles has a tremendous impact on powder-processing industries, especially for hygroscopic amorphous powders. A wide variety of experimental methods has been developed to measure at what combinations of temperature and moisture content material becomes sticky. This review describes, for each method, how so-called stickiness...
