Arbitrary thickness profile metrology of low‐Z and monolithic material components with a single X‐ray projection

Journal of Synchrotron Radiation, Volume 32, Issue 5, Page 1310-1318, September 2025.
A thickness metrology method based on X‐ray phase contrast imaging is proposed. By precisely retrieving the phase shift of X‐rays passing through the sample, high‐precision arbitrary thickness profile measurement can be achieved with a single X‐ray projection. A measurement case of a microlens array is presented to demonstrate the effectiveness of this

Performance of hybrid diffuse reflectance spectroscopy (HDRS‐ISO 23698) methodology for assessment of sunscreen protection in the ALT‐SPF Consortium validation study

International Journal of Cosmetic Science, Volume 47, Issue S1, Page 53-77, September 2025.
Hybrid Diffuse Reflectance Spectroscopy (HDRS), now ISO 23698, demonstrated bioequivalence to gold‐standard SPF, UVA‐PF, and CW methods, achieving similar accuracy with improved variability after training. This new non‐erythemal approach enables safe non‐invasive sunscreen performance assessment on human skin, expanding possibilities for evaluating ...

Dispersive X‐ray absorption spectroscopy using independent grazing‐incidence focusing and convexly bent Bragg‐crystal dispersing optics

Journal of Synchrotron Radiation, Volume 32, Issue 4, Page 1068-1084, July 2025.
A dispersive X‐ray absorption spectroscopy instrument has been developed and implemented at the Advanced Photon Source's Advanced Spectroscopy Beamline. The instrument uses a convexly bent Bragg‐crystal analyzer to disperse a polychromatic X‐ray beam and independent Kirkpatrick–Baez mirrors for focusing, thereby providing a simple and flexible method ...

Engineered Hydrogels for Organoid Models of Human Nonalcoholic Fatty Liver Disease

Advanced Science, Volume 12, Issue 22, June 12, 2025.
Nonalcoholic fatty liver disease (NAFLD) is characterized by lipid accumulation and extracellular matrix stiffening. An in vitro NAFLD model is developed using engineered hydrogels (G′ ≈ 1–6 kPa) and iPSC‐derived hepatic organoids. It is demonstrated that higher stiffness can increase lipid droplet accumulation, fibrosis, and metabolic dysregulation ...

Synthetic fibres and steel fibres in concrete with regard to bond strength and toughness [PDF]

, 2009
The ability of fibre reinforced concrete composites to absorb energy has long been recognised as one of the most important benefits of the incorporation of fibres into plain concrete” (Golpalaratham and Gettu 1995).

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the assessment of the impact of fox population dynamics on public health

Food Risk Assess Europe, Volume 3, Issue 2, April 2025.
ABSTRACT The Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents.

Operando X‐Ray Tomoscopy of Laser Beam Welding

Advanced Science, Volume 12, Issue 9, March 6, 2025.
An advanced way of laser beam guidance in the welding of die‐cast aluminum by beam modulation is investigated in 3D over time using X‐ray tomoscopy. New insights into the interaction of the keyhole with the forming porosity are gained. These dynamic changes are quantified with a temporal resolution of 10 ms and a reduction in porosity and surface ...

Optical evaluation of internal damage to human hair based on second near‐infrared window polarization microscopy

International Journal of Cosmetic Science, Volume 46, Issue 6, Page 850-864, December 2024.
A second near‐infrared (NIR) window microscope with circularly polarized optics noninvasively visualizes the internal state of hair and quantitatively evaluates hair damage caused by bleaching, permanent waveing, LiBr treatment, and heating. This method has high potential as a standard evaluation tool in the hair care field.

Volumetric changes of the enteric nervous system under physiological and pathological conditions measured using x‐ray phase‐contrast tomography

JGH Open, Volume 8, Issue 9, September 2024.
The assessment of neural tissue in the enteric nervous system by X‐ray phase‐contrast micro‐computed tomography (PC‐µCT) showed that the ratio of neural tissue volume/total tissue volume was higher in controls than in patients with enteric neuropathy (P = 0.013). The patient with the longest disease duration had the lowest ratio.

Male genitalia, hierarchical homology, and the anatomy of the bullet ant (Paraponera clavata; Hymenoptera, Formicidae)

Journal of Morphology, Volume 285, Issue 9, September 2024.
We present a multimodal anatomy of the male genitalia of the bullet ant, Paraponera clavata. Using this as a model system, we expand and refine on the 5‐category system of homology classification proposed by Meneganzin et al. (2024) and we present evidence supporting the penis‐coxopod theory of male genitalic homology in male insects. Abstract The male
