Systematic ab initio structure prediction was applied for the first time to predict low energy surface reconstructions by employing the minima hopping method on the α-boron (111) surface. Novel reconstruction geometries were identified and carefully characterized in terms of structural and electronic properties. Our calculations predict the formation of a planar, monolayer sheet at the surface,...

Background and Objectives: Boron is widely found in raw materials and wastewater of the tile industry and its removal from aquatic environments is very complex. The aim of this study was to remove boron from wastewater of ceramic tile industry using coagulation and flocculation-adsorption process. Materials and Methods: This was an experimental study. Initially, for the coagulation process, pH...

Boron is an essential plant micronutrient that is involved in the cell wall and membrane structure and functioinig. Boron is often found in high concentrations in association with agriculture in arid  and semi-arid regions. In order to investigate the effect of zinc sulfate on some morphological, physiological and biochemical characteristics of two grapvine cultivars under toxicity of boron, a ...

In the presence of polyborates (detected by (11)B-NMR) the formation of a weak Eu(III) borate complex (lg β11 ~ 2, estimated) was observed by time-resolved laser-induced fluorescence spectroscopy (TRLFS). This complex is a precursor for the formation of a solid Eu(III) borate species. The formation of this solid in solution was investigated by TRLFS as a function of the total boron concentratio...

Evaluation of three subclasses of boron difluoride formazanate complexes bearing o-, m-, and p-anisole N-aryl substituents (Ar) as readily accessible alternatives to boron dipyrromethene (BODIPY) dyes for cell imaging applications is described. While the wavelengths of maximum absorption (λmax ) and emission (λem ) observed for each subclass of complexes, which differed by their carbon-bound su...

due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...

today, persian poetry is of great importance to many scholars around the world. the interest and attention of various cultures toward such a fine literature has given quite a good motivation for a comparative study. the major concern of the study is to investigate how nature is depicted through the works of the great english poet, william wordsworth (1770-1850) and the outstanding contemporary ...

We report in vitro and in vivo evaluation of a newly designed trifunctional theranostic agent for targeting solid tumors. This agent combines a dendritic wedge with high boron content for boron neutron capture therapy or boron MRI, a monomethine cyanine dye for visible-light fluorescent imaging, and an integrin ligand for efficient tumor targeting. We report photophysical properties of the new ...

In arid and semi arid regions with high boron content in irrigation water, boron toxicity is a considerable problem. Critical levels of boron in irrigation water variy between 1 and 10 mg/l for sensitive and resistant plants, respectively. In southern parts of Iran especially large citrus production region as Jahrom and Giroft cities, high boron content in irrigation water at toxic levels in mo...
