Nanostructured photoactive systems are promising for applications such as air and water purification, including self-cleaning coatings. In this study, mesoporous TiO2 sol-gel coatings with different pore structures were prepared modified silver by two methods: the “mixing” method adding AgNO3 to precursor sol, “impregnation” immersing samples in solution (0.03 1 M) followed heat treatment. Our ...

acute lymphoblastic leukemia (all) is the most prevalent hematological malignant tumor during childhood. unilateral infiltration into the gums is less prevalent and more often observed in the aml type. a 12-year-old girl with symptoms of pain and swelling in the buccal vestibule and also at the posterior part of the right palate of the maxilla was referred to a private dental office. the patien...

rise in temperature occurred after soil temperature was measured in different time series. in this article, ldf (logarithmic derivative filter) innovative method is applied to detect anomalies. this method tests soil temperature time series for 12 earthquakes in iran with magnitudes of either five or greater than five. results from this method were collected. based on the results of ldf method ...

in this paper, plate-like nio nanoparticles were prepared by one-pot solid-state thermal decomposition of nickel (ii) schiff base complex as new precursor. first, the nickel (ii) schiff base precursor was prepared by solid-state grinding using nickel (ii) nitrate hexahydrate, ni(no3)2∙6h2o, and the schiff base ligand n,n′-bis-(salicylidene) benzene-1,4-diamine) for 30 min without using any solv...

Nanoparticles have a size of 1nm-100nm in any one the three dimensions. Smaller nanoparticles different physical, chemical and biological properties than atoms molecules. Metals, non-oxide ceramic materials, metal oxides, silicates, polymers, organic biomolecular components can be used to create material nanoparticles. come various shapes, like spheres, platelets, cylinders, tubes. Green synthe...

We report the controlled synthesis of polymer-stabilized silver nanoparticles (AgNPs) by using microfluidic devices. The microfluidic-based method enabled preparation sub-50 nm AgNPs which are much more homogenous compared to those produced in batch reactors where control over flow and mixing conditions was not performed. concentration precursor (silver nitrate - AgNO3) can be tuned reach small...

Coriander leaves and seeds have been highly appreciated since ancient times, not only due to their pleasant flavors but also due to their inhibitory activity on food degradation and their beneficial properties for health, both ascribed to their strong antioxidant activity. Recently, it has been shown that coriander leaf extracts can mediate the synthesis of metallic nanoparticles through oxidat...
