Decisions about recreational beach closures would be enhanced if better estimates of surfzone contaminant transport and dilution were available. In situ methods for measuring fluorescent Rhodamine WT dye tracer in the surfzone are presented, increasing the temporal and spatial resolution over previous surfzone techniques. Bubbles and sand suspended by breaking waves in the surfzone interfere wi...
During the light-harvesting process of dye-sensitized solar cells (DSSCs), the hole localized on the dye after the charge separation yields an oxidized dye, D(+). The fast regeneration of D(+) using the redox pair (typically the I(-)/I3(-) couple) is critical for the efficient DSSCs. However, the kinetic processes of dye regeneration remain uncertain, still promoting vigorous debates. Here, we ...
The photochemotherapeutic properties of a novel benzophenothiazine, 5-ethylamino-9-diethylaminobenzo[a]phenothiazinium chloride, were assessed in vitro and in vivo against two murine mammary sarcoma models (EMT-6 and RIF). Photodynamic therapy (PDT) of EMT-6 and RIF cells following a 30-min incubation with dye (0.4 microgram/ml) and a light dose of 3.3 J/cm2 killed 87.0 and 99.6% of the cells, ...
Background and Objective: Existence of dye in water resources and wastewater can cause the environmental problems that must be removed from water. There has been some increase in the use of low-cost adsorbent substances as sewage treatment over recent years. Therefore, the purpose of this study was to optimize dye (RO16) removal from aqueous solutions by quarternary ammonium chloride (C6H15Cl2N...
Hair dye is one of the most popular cosmetic products which are used more widely and frequently to improve an individual’s appearance. Although the genotoxic effects of dye ingredients are widely reported, hair dye in its usable form is not reported extensively. In this contribution, we report the possible mode of interaction of hair dye with DNA which leads to genotoxicity. The effect of dye D...
Introduction and purpose: Treatment of dye wastewater produced by textile industries is a major challenge for the environment. About 15% of the total produced dyes in the world are released in sewages during dyeing activities. Alizarin red S (ARS), a synthetic dye produced from Alizarin sulfonate is the most widely used dye in the textile industry. The aim of this study was ...
introduction: the purpose of this in vitro study was to compare the coronal seal of four temporary filling materials, coltosol, zonalin, zamherir, and intermediate restorative material (irm) by the india ink dye penetration test. materials and methods: endodontic access preparations were prepared in 120 extracted intact human premolars. the teeth were randomly divided into six groups including ...
introduction: granuloma faciale is an uncommon inflammatory dermatosis which usually affects the face and is often resistant to treatment. case report: a 39-year-old english lady with fitzpatrick skin phototype ii presented with typical lesions of granuloma faciale, confirmed on biopsy, on her cheeks and nose. treatment with scleroplus pulsed dye laser (candela corporation, wayland, mass) produ...
