Role of near-surface environment in tuning electrochemical CO2 reduction reaction and H2 evolution reaction
This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

Minder vlees betekent meer land (en dat kunnen we gebruiken om het klimaat een handje te helpen)
Door de komst van alternatieven kunnen we de komende decenia radicaal minderen met vlees, zuivel en andere dierlijke producten. Dit zou enorme hoeveelheden land vrijmaken om schone energie te produceren en koolstof uit te atmosfeer te halen. Milieuwetenschappers Laura Scherer en Oscar Rueda schrijven…

The dynamic organization of prokaryotic genomes: DNA bridging and wrapping proteins across the tree of life
Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.
