This study was aimed at investigating the photocatalytic degradation of ciprofloxacin (CIP) antibiotic in aqueous solution using immobilized ZnO nanoparticles on glass plate. X-ray diffraction, atomic force microscopy, and scanning electron microscopy were applied to characterize the nanoparticles. To do so, the ZnO nanoparticles were synthesized through the chemical precipitation method and we...

In this work, the effects of co-precipitation temperature and post calcination on the magnetic properties and photocatalytic activities of ZnFe2O4 nanoparticles were investigated. The structure, magnetic and optical properties of zinc ferrite nanoparticles were characterized by X-ray diffraction (XRD), vibrating sample magnetometry and UV–Vis spectrophotometry techniques.  The XRD re...

In order to investigate light and temperature effects on germination of different ecotypes of wild mustard  (Sinapis arvensis L.), seeds were collected from four regions: Fars, West Azarbayjan, Khouzestan and Mazandaran Provinces. Seed size and weight, difference of dormancy state among the ecotypes, seed germination in differential light and temperature conditions were studied. The results sho...

abstract this experiment, conducted to examine the effects of temperature and photoperiod on seed germination of watergrass (echinochlo aoryzoides) as a new-introduced and barnyardgrass (e. crus-galli) as a common weed species in rice fields of guilan province. this study was consisted of two separate experiments. at the first study, germination responses of two species to different temperature...

the use of low level laser to reduce pain, inflammation and edema, to promote wound, deeper tissues and nerves healing, and to prevent tissue damage has been known for almost forty years since the invention of lasers. this review will cover some of the proposed cellular mechanisms responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption pea...

Background and objectives: Crocus sativus L. (Iridaceae) commonly known as saffron, is a popular spice which is used for its pleasant aroma and favored color. Regarding the previous reports about the neuroprotective be...

In this research, Carbon-doped TiO2 nano-photocatalyst is synthesized via sol-gel technique and photo-catalytic degradation of phenol has been studied under ultraviolet and visible light irradiation in a fluidized bed reactor. Various techniques are used to characterize TiO2 nano-photocatalyst such as X-Ray Diffraction, Fourier transform infrared spectroscopy,  Energy Disp...

The species Gracilariopsis persica was first described by Bellorin et al. (2008). G. persica grows from late September to July and shows high growth rate from January to May in the Persian Gulf. Tissue growth and branch induction of red seaweed, Gracilariopsis persica from the Persian Gulf investigated under various culture levels of temperature, light intensity, photoperiod, salinity, initial ...
