Postma, J.I. (author), Ferrari, A. (author), Bottger, A.J. (author)Surface compositions play a predominant role in the efficiency and lifetime of membranes and catalysts. The surface composition can change during operation due to segregation, thus controlling and predicting the surface composition is essential. Computational modelling can aid in predicting alloy stability, along with designing surface alloys...journal article 2023

(author)Sodium borohydride (NaBH<sub>4</sub>) has a high hydrogen (H<sub>2</sub> ) gravimetric capacity of 10.7 wt %. NaBH<sub>4</sub> releases H<sub>2</sub> through a hydrolysis reaction in which aqueous NaB(OH)<sub>4</sub> is formed as a byproduct. NaB(OH)<sub>4</sub> strongly influences the thermophysical properties of aqueous solutions (i.e.,...journal article 2023

(author)Saccharomyces cerevisiae, whose evolutionary past includes a whole-genome duplication event, is characterized by a mosaic genome configuration with substantial apparent genetic redundancy. This apparent redundancy raises questions about the evolutionary driving force for genomic fixation of “minor” paralogs and complicates modular and...journal article 2022

Postma, Tom (author), Jansen, J.D. (author)Over the past decade, a steep increase in the number of seismic events has been observed in the Groningen gas field, the Netherlands. It is generally accepted that these are induced by compaction of the reservoir rock due to extensive depletion, causing a buildup of strain energy in faults that may be released seismically. We address the...journal article 2018
