Pollution associated with petrogenic hydrocarbons is increasing in Antarctica due to a combination of human activity and the continent’s unforgiving environmental conditions. The current study focuses on ability cold-adapted crude microbial consortium (BS24), isolated from soil north-west Antarctic Peninsula, metabolise diesel fuel as sole carbon source shake-flask setting. Factors expected inf...

Electroplated rhodium foil was employed as the target for cyclotron production of palladium-103. An electrodissolution apparatus was found better than other dissolution methods in terms of personnel shielding and palladium-103 yield. The ion-exchange column chromatography method was simple and effective for the purification of palladium-103 and the final stripping agent of NH4Cl + NH3(1:1) was ...

Thallium (Tl) is a highly toxic heavy metal that poses threat to various organisms, including human beings. In plants, Tl mostly present as the uncomplexed Tl+ species, and its uptake by plants follows similar trend of other monovalent ions such NH4+, Cs+, K+, Rb+, others. this study, we investigated relationships between concentrations in barley sunflower extractable-Tl acidic, neutral, alkali...

Poly (urea-formaldehyde) (PUF) shelled dicyclopentadiene (DCPD) microcapsules were prepared by in-situ polymerization technology for self-healing concrete applications. It’s found, during the process, sodium dodecyl benzene sulfonate (SDBS) behaves better in emulsification of DCPD than other surfactant of sodium lauryl sulfate (SLS) and styrene maleic anhydride copolymer (SMA), and the addition...

Monodisperse single-crystal hollow cerium dioxide nanocubes with exposed (001) facets have been synthesized with the assistance of ammonium chloride (NH4Cl) and polyvinylpyrrolidone (PVP) in a water and ethanol system. A series of experiments indicate that ammonium ion plays an important role in the formation of the hollow structure and PVP plays a key role in the formation of a cubic shape. Th...

A catalytic polarographic method for the determination of microgram quantities of Ce(IV) is developed based on the catalytic currents of cerium(IV) in the presence of NH4Cl – NH4OH at pH 6.2 with piperazine. Piperazine produces catalytic current with Ce(IV) at peak potential -0.1 to -0.6 V vs. SCE. The procedure was applied for the estimation of Ce(IV) in water samples. The method is simple, se...
