(author), De Lange, Nick (author), Engel, Andreas (author), Aubin-Tam, M.E. (author)AAA+ proteases are degradation machines that use ATP hydrolysis to unfold protein substrates and translocate them through a central pore toward a degradation chamber. FtsH, a bacterial membrane-anchored AAA+ protease, plays a vital role in membrane protein quality control. How substrates reach the FtsH central pore is an open key question...journal article 2020

Sideris, Eva Ann (author), De Lange, Hendrik Cornelis (author), Hunt, A. (author)Microfluidic devices and micro-pumps are increasingly necessitated in many fields ranging from untethered soft robots, to pharmaceutical and biomedical technology. While realization of such devices is limited by miniaturization constraints of conventional actuators, these restrictions can be resolved by using smart material transducers...journal article 2020

Van Der Linden, Toon I. (author), De Lange, Dirk A. (author), Korff, M. (author)The effect of a soft layer on the cone resistance of a sand layer has been studied extensively, but the same cannot be said for the case of multi-layered deposits with many (thin) alternating soil layers. For geotechnical analyses based on cone penetration test data it is difficult to estimate a representative value of the cone resistance...journal article 2018

(author), Morozov, Dmitry (author), Trappe, Neil A. (author), Doherty, Stephen (author)The next generation of far infrared space observatories will require extremely sensitive detectors that can be realized only by combining extremely low intrinsic noise with high optical efficiency.

Wiegers, T. (author), De Lange, C.J.M. (author), Vergeest, J.S.M. (author)Q board interviews can be applied as an effective method to get insight in the opinions of participants. Q board interviews form the interviewing part of Q methodology. Q methodology can be used to identify typical sets of opinions. However, in many studies, the research goal is to order opinions and see which ones play the most important roles,...conference paper 2014
