Luesutthiviboon, S. (author), Ragni, D. (author), Avallone, F. (author), Snellen, M. (author)This study focuses upon a new permeable topology design concept as an alternative to porous metal foams, for turbulent boundary layer trailing-edge (TBL-TE) noise attenuation.

Xu, Y. (author), Šavija, B. (author)Conventionally, the properties of cementitious materials are tailored by a simple but efficient method: mixture proportion design. For a given cementitious mixture, the chemical and physical properties of cementitious materials have already been determined. Consequently, the mechanical performance of the hardened cementitious material is...journal article 2021

Tissen, L.N.M. (author)This article uses the COVID –19 crisis to re –evaluate the importance of reproductions – 3D prints – for art’s authenticity, and their significance in keeping art museums meaningful in a rapidly changing world. The fixation on ‘auratic experiences’, inherent to artworks’ materiality is integral to contemporary art theory and museum practice,...journal article 2021

Ritzen, L. (author), Montano, V. (author), Garcia, Santiago J. (author)The use of self-healing (SH) polymers to make 3D-printed polymeric parts offers the po-tential to increase the quality of 3D-printed parts and to increase their durability and damage toler-ance due to their (on-demand) dynamic nature. Nevertheless, 3D-printing of such dynamic poly-mers is not a straightforward process due to their polymer...journal article 2021

(author)The currently available treatments for inner ear disorders often involve systemic drug administration, leading to suboptimal drug concentrations and side effects. Cochlear implants offer a potential solution by providing localized and sustained drug delivery to the cochlea. While the mechanical characterization of both the implants and their...journal article 2024
