The Improvement of Performance through Minimizing Scallop Size in MEMS Based Micro Wind Turbine

open access: yesMicromachines, 2021
In this paper we report on the improvement of performance by minimizing scallop size through deep reactive-ion etching (DRIE) of rotors in micro-wind turbines based on micro-electro-mechanical systems (MEMS) technology.

Functional variation in butterfly egg pore traits: The potential role of climate

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Immobile eggs of terrestrial animals are exposed to variable environmental conditions. Insect egg pores, critical for gas exchange (aeropyles) and fertilisation (micropyles), are ecologically important yet understudied.

A Natural History of ‘Annoyances’: Knowing Weeds and Weeding Knowledge in the Early Royal Society and its ‘Georgicall Committee’

open access: yesRenaissance Studies, EarlyView.
ABSTRACT Seventeenth‐century virtuosi often figured themselves as epistemic weeders, grubbing up rank thickets of accumulated error. In this article, I argue that these metaphors were unnerved by the shifting status of weeds—ostensibly unwanted plants from the margins of cultivated space, unploughed land or the disturbed soils between growing crops—in ...

‘In Curaçao They Celebrate King's Day Abundantly!’ – Diachronic Representation of (Post)colonial Communities in Dutch Geography Textbook Discourse (1946–2018)

open access: yesTijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract Postcolonial textbook research leads us to reflect on the representation of (post)colonial communities in educational media for adolescents in geography education. This paper contributes to this scholarship through Critical Discourse Analysis tracing how nine Dutch geography textbooks (1946–2018) have represented such communities from ...

Is switching to T-DM1 still justified in HER2-negative residual breast cancer after neoadjuvant systemic therapy?

open access: yesBreast
The standard of care for HER2-positive and hormone receptor-positive breast cancer patients who receive neoadjuvant chemotherapy (NACT) combined with trastuzumab, with or without pertuzumab, is to continue with adjuvant T-DM1 in cases of an incomplete ...

High‐Throughput Mechanical Rupture of Nuclear Envelope and the Intracellular Dynamics of Massive Wound Repair

open access: yesAdvanced Science, Volume 13, Issue 55, 5 October 2026.
A microfluidic device with monolithically integrated nanostructures enables high‐throughput wounding of the cell membrane and nuclear envelope. The spatial distribution of charged multivesicular body protein 4B (CHMP4B) within the cell is mapped before and after wounding, showing involvement in repair of both the cell membrane and nuclear envelope ...
