Fabry-Pérot white light interferometry is at the heart of the surface force apparatus (SFA). One of the applications of SFA is the measurement of properties of sub-nanometer-confined fluids. For the determination of the properties of a confined fluid, the absolute accuracy of SFA is directly linked to the accuracy of the parameters describing the optical layers of the interferometer, particularly the micrometer thick mica spacer layers.

Light is a major environmental factor that regulates circadian rhythms and pineal melatonin synthesis. While the influence of nighttime light exposure on melatonin suppression has been extensively investigated, much less is known about the impact of photophase light wavelength on pineal function. The aim of the study was to determine the influence of monochromatic light during the photophase on diurnal changes in melatonin-related indoles in the rat pineal gland.

Background: Small intestinal endoscopic ultrasonography (SIEUS) enables the comprehensive analysis of the origin and sonographic characteristics of protruding submucosal lesions. Current evidence is limited to case reports. We aimed to investigate the application value of SIEUS for protruding lesions of the small intestine.

The controlled folding of synthetic polymers, mimicking the complex behaviors of biomacromolecules, offers the potential to create sophisticated nanostructures with diverse functionalities. Of great significance is the integration of functionalization directly with chain folding, especially through the incorporation of artificial elements not found in nature, which allows unprecedented flexibility in materials design. However, this approach faces significant synthetic challenges, owing to the intricate integration of multiple chemical processes within a single chain.
