Full-field imaging of guided ultrasonic wave fields using lensless digital holography

open access: yesJournal of the European Optical Society-Rapid Publications
In this work, we present the full-field measurement of guided ultrasonic waves (GUWs) on technical surfaces using lensless digital holography. The setup works with a pulsed coherent laser illumination and a complementary metal-oxide semiconductor (CMOS ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Fast simulation of the influence of a refractive free-form microstructure on a wave field based on scalar diffraction theory

open access: yesJournal of the European Optical Society-Rapid Publications
We present a novel fast simulation approach to simulate the influence of refractive freeform microstructures on a wave field. The FRISP (Finite Refractive Index Selective Propagation) method combines the Rayleigh-Sommerfeld diffraction integral with a ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Overview of Skin Whitening Agents: Drugs and Cosmetic Products

open access: yesCosmetics, 2016
Depigmentation and skin lightening products, which have been in use for ages in Asian countries where skin whiteness is a major esthetic criterion, are now also highly valued by Western populations, who expose themselves excessively to the sun and ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Laser-tracker-based reference measurement for geometric calibration of phase-measuring deflectometry with active display registration [PDF]

open access: yesJournal of Sensors and Sensor Systems
Phase-measuring deflectometry (PMD) with active display registration (ADR) is a ray-optics-based technique for the shape measurement of specular surfaces.
