- The UV-cured lenses maintained their shape in a water-swollen state and exhibited less tearability compared to conventional lenses, despite having slightly reduced water content and lower water contact angles.*
Article Abstract
In this study, we synthesized three novel acrylic monomers with a cinnamate group. We then mixed each monomer with 2-hydroxyethyl methacrylate (HEMA) to prepare soft contact lenses through bulk polymerization. Fourier transform infrared (FT-IR) and UV spectral analyses confirmed that the cinnamate group in the polymer undergoes a photodimerization reaction via UV irradiation. After UV curing, the present lenses stably maintained their shapes even in a water-swollen state and showed significantly improved mechanical properties compared to conventional lenses manufactured using a cross-linking agent. These lenses showed slightly lower water contact angles than the conventional lenses, although the water content was slightly reduced. The present photodimerization cross-linking method was found to be useful in reducing the tearability of soft lenses.

Understanding the values and origin of fundamental physical constants, one of the grandest challenges in modern science, has been discussed in particle physics, astronomy and cosmology. More recently, it was realized that fundamental constants have a biofriendly window set by life processes involving motion and flow. This window is related to intrinsic fluid properties such as energy and length scales in condensed matter set by fundamental constants.

Nature-inspired superhydrophobic materials have attracted considerable interest in blood-contacting biomedical applications due to their remarkable water-repellent and self-cleaning properties. However, the interaction mechanism between blood components and superhydrophobic surfaces remains unclear. To explore the effect of trapped air on platelet adhesion, we designed four distinct hydrophobic titanium dioxide (TiO) nanostructures with different fractions of trapped air.

Background: The microvasculature of the central nervous system (CNS), which delivers oxygen and nutrients and forms a critical barrier protecting the CNS, is deleteriously affected by both Alzheimer's Disease (AD) and Type 2 Diabetes (T2D). Previous studies have shown pericyte dropout and vessel constriction in brain capillaries in AD, while other studies have shown pericyte bridging and dropout in retinal capillaries in T2D. T2D patients have increased risk of AD, suggesting potentially related microvascular pathological mechanisms.

Organic multilayer systems, which are stacked layers of different organic materials, are used in various organic electronic devices such as organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). In particular, OFETs are promising as key components in flexible electronic devices. In this study, we investigated how the inclusion of an insulating tetratetracontane (TTC) interlayer in ambipolar indigo-based OFETs can be used to alter the crystallinity and electrical properties of the indigo charge transport layer.
