A robust material for the production of microfluidic liquid-liquid extraction chips
Evaluation of a robust ALD coating to reduce irradiation-induced surface modifications on polymers and quartz for the usage of microfluidic liquid-liquid extraction chips
Microfluidic extraction is a promising alternative for existing extraction methods of radioisotopes due to the high surface-to-volume ratio. When assessing the compatibility of microfluidic material with the extraction system, there are three critical aspects—compatibility with o
...
Electrochemical reduction of CO2 using renewable energy sources is one of the promising avenues to pursue towards mitigating the emissions of the notorious CO2. However, the CO2 electrolysis in aqueous systems, due to the low solubility of CO2, are severely limited by mass transf
