PURPOSE The purpose was to develop suitable in vitro methods to detect ocular epithelial cell damage when exposed to UV radiation, in an effort to evaluate UV-absorbing ophthalmic biomaterials. METHODS Human corneal epithelial cells (HCEC), lens epithelial cells (HLEC), and retinal pigment epithelial cells (ARPE-19) were cultured and Ultraviolet A/Ultraviolet B (UVA/UVB) blocking filters and ...

The photocatalytic degradation of dimethyl phthalate (DMP) in aqueous TiO2 suspension under UV illumination has been investigated using oxygen (O2) and ferrate (Fe(VI)) as electron acceptors. The experiments demonstrated that Fe(VI) was a more effective electron acceptor than O2 for scavenging the conduction band electrons from the surface of the catalyst. Some major intermediate products from ...

Nanoimprint lithography (NIL) is a promising nanomanufacturing technology that offers an alternative to traditional photolithography for manufacturing next-generation semiconductor devices. This technology involves coating an ultraviolet (UV)-curable monomer layer on the substrate and then imprinting it with a template containing topography corresponding to the desired substrate features. While...

The purpose of this study was to compare the presence or absence of UV irradiation on the separation performance and morphology of the TiO2-assembled thin film membranes (in different concentrations). Furthermore, an attempt was made to show and compare the effect of the presence of TiO2 nanoparticles in aqueous and organic phases during the interfacial polymerization proc...

Prior ultraviolet (UV) irradiation of the site of application of hapten on murine skin reduces contact sensitization, impairs the ability of dendritic cells in the draining lymph nodes (DLN) to present antigen, and leads to development of hapten-specific suppressor T lymphocytes. We tested the hypothesis that UV-induced DNA damage plays a role in the impaired antigen-presenting activity of DLN ...

UV radiation induces skin cancer primarily by its DNA-damaging properties, but also by its capacity to suppress the immune system. The photoisomer of urocanic acid (UCA), cis-UCA, is an important mediator of UV-induced immunosuppression and is involved in the inhibition of tumor immunity. The immunomodulatory cytokine IL-12 is known to counteract many of the immunosuppressive effects of UV radi...

Surface tension of material surfaces and interfaces is an important parameter that affects wetting and adhesion. Surface tension can be divided into three components: Lifshitz–van der Waals component, acid component, and base component. In this study, the three-liquid-probe method was used to investigate the surface tension and its three components of various surfaces of electronic packaging ma...
