The electrocatalytic ability of the iron-substituted crown-type polyoxometalate (POM) Li4K16[P8W48O184Fe16(OH)28(H2O)4]66H2O2KCl (P8W48Fe16) towards the reduction of both nitrite and hydrogen peroxide reduction has been studied in both the solution and immobilized states for the POM. P8W48Fe16 was surface immobilised onto carbon electrode surfaces through employment of the layer-bylayer techn...

In this study, the zonality method has been used to separate geochemical anomalies and calculate erosional levels in regional scale for porphyry-Cu deposit, Abrisham-Rud (Semnan province, East of Iran). maps multiplicative haloes, co-existence both supra-ore elements sub-ore local maxima implied blind mineralization northwest study area. Moreover, considering calculated indices two previously p...

A large amount of accurate river cross-section data is indispensable for predicting river stages. However, the measured river cross-section data are usually sparse in the transverse direction at each cross-section as well as in the longitudinal direction along the river channel. This study presents three algorithms to resample the river cross-section data points in both the transverse and longi...
