CdSe nanostructures were synthesized by using green chemical route as starch was used as capping agent. XRD, HR-TEM, SEAD, UV and PL studies were made for structural and optical properties of the prepared sample. Film morphology and the thickness measurement of n-CdSe were carried out with AFM analysis. I-V characteristics curve of this junction confirmed the formation of Schottky contact betwe...
Background and purpose: Highly consumption of antibiotics and their entrance into the environment has increased concerns all over the world. These compounds enter to the environment through an incomplete metabolism and a considerable amount of them cannot be removed using usual waste filtration systems. Therefore, the present study aimed to investigate the feasibility of using ultraviolet radia...
It has been said that aside from skin, the organ most susceptible to sunlight-induced damage is the eye. In view of this, it can be argued that the optical industry and the eye care professional have an obligation, or at least, an opportunity, to educate the public more widely on the dangers of ocular exposure to UV and how best to achieve protection. This article summarises our understanding o...
the role of the antioxidant defense system was studied in brassica napus, and subjected todifferent supplementary bands of ultraviolet radiation (uv-a, uv-b and uv-c). this study showed thatuv-b and uv-c induced oxidative stress as evidenced by an increase in lipid peroxidation and totalascorbate content. under uv-b and uv-c treatments, flavonoids and anthocyanins were increasedsignificantly co...
Protein deposition is one of the most frequent contaminants occurring on hydrophilic contact lenses and may modify the lens optical properties. The silicone-hydrogel contact lenses usually adsorb a lower amount of proteins than the conventional hydrogel ones. However it is important to study the influence of protein deposits on some silicone-hydrogel contact lenses properties, such as UV-Visibl...
Tinosorb® M is a widely used ultraviolet (UV) filter complex provided as an emulsion that contains the UV filter methylene bis-benzotriazolyl tetramethylbutylphenol (MBBT) (45–55%, CAS no. 103597-45-1), decyl glucoside (6–10%), propylene glycol (0.2–0.6%), and xanthan gum (0.1–0.5%). Fewer than 15 cases of contact allergy to Tinosorb® M have been published (1–7), and, to our knowledge, in only ...
wastewater from molasses processing contains a large amount of coloured substances that give a recalcitrant dark brown colour and high organic load to the effluent. photocatalytic decolourization of molasses wastewater was performed using titanium dioxide catalyst coated on the surface of south african natural zeolite using the solid-solid dispersion method. addition of hydrogen peroxide as an ...
Background and purpose: Aniline is widely used as raw material in many chemical industries. The aim of this study was to survey the photocatalytic degradation of aniline using magnesium oxide nanoparticles from aqueous solutions. Materials and methods: An experimental study was carried out in a 2 L volume batch reactor. Various parameters such as pH (3-11), dose of nanoparticles (0.1-1), con...
The effects of suberythematous levels of UV-B radiation on the development of of cutaneous leishmaniasis were studied in B10.129(10M) mice. Doses of 15 mJ cm-2 UV-B applied locally to the injection site suppressed the development of skin lesions after the inoculation of Leishmania major promastigotes. The primary targets of UV-B radiation appeared to be host cells and not leishmanial parasites,...
UV light is an immune system regulator. In a mouse model of contact hypersensitivity, irradiation causes tolerance in antigen-specific manner by inducing regulatory T cells (Tregs). Expanded Tregs are observed UVB-irradiated skin and draining lymph nodes. The best conditions to induce UV-expanded (UV-Tregs) unknown. We focused on UVC UVB wavelengths investigate UV-Tregs induction identify chang...
