Sub‐100 Nanometer Focusing of Hard X‐rays Using SU‐8 Compound Kinoform Focusing Lenses

open access: yesAdvanced Photonics Research, Volume 7, Issue 4, April 2026.
A novel aberration‐free X‐ray compound refractive lens design based on Cartesian oval curve is presented. Achieving a vertical focal spot size of 70.8 nm using knife‐edge scanning with a 200 μm incident aperture. Wavefront reconstruction via knife‐edge imaging further resolves a refined focal spot of 56 nm.

Physical activity and meal timing alignment with chronotype and their associations with glucose metabolism: The Maastricht Study

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 4, Page 3295-3304, April 2026.
Abstract Aims Little is known about how the alignment between daily behaviours, such as physical activity and eating, and chronotype relates to glucose metabolism. We investigated whether alignment of physical activity and meal timing with chronotype was associated with glycaemic parameters and with prediabetes or type 2 diabetes (T2DM).

Margins or mainstream: a cross-sectional study on consensual and non-consensual non-monogamy in the general Belgian adult population

open access: yesHumanities & Social Sciences Communications
Non-monogamy refers to a type of relationship wherein sexual and/or romantic exclusivity is not upheld. While scientific research has been increasingly focusing on the prevalence of non-monogamy in Western societies, studies typically suffer from ...

Electrically Tunable On‐Chip Topological Photonics with Integrated Carbon Nanotubes

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This work demonstrates electrically tunable on‐chip topological THz devices by integrating 2D carbon nanotube (CNT) sheets with valley‐Hall photonic crystals, enabling broadband transmission modulation (71% modulation depth) and tunable narrowband filtering (0.54 GHz shift) through electrically induced thermal tuning. This advancement paves the way for
