Increased risk of ill-health and diseases has been associated with employment in the ferro-alloy factory. Since measurement of transition metals in human blood and hair along with respective exposure rates, provides a means of assessing individual risk, it has been the most important part of the study. In the study majority of the elements in the transition series, such as, vanadium (V), chromi...

Numerous water-treatment marital have been developed during the past few years, including adsorbents., catalytic reduction behavior of carboxylated alginic acid derivatives has investigated against harmful organic dyes Methyl Orange (MO) and Congo Red (CR). Alginic was firstly oxidized through an easy addition KMnO 4 as oxidizing agent. A (CAA) interacted with selected metal ions (Sn, Fe, Ni, Z...

A unique method is described for inhibiting nitrogenase. When Clostridium pasteurianum nitrogenase is assayed in the presence of the Mo-Fe protein of Azotobacter vinelandii, all the characteristic activities of nitrogenase are inhibited. C. pasteurianum nitrogenase is unaffected by the Fe protein of A. vinelandii. The Fe protein, but not the Mo-Fe protein of C. pasteurianum, inhibits A. vinelan...

Combining first-principles calculations with recently developed statistical physics tools, we determine carbon diffusion mechanisms and the resulting coefficients in pure-Fe weakly alloyed ${M}_{3}\mathrm{C}$ cementites. The predicted ${\mathrm{Fe}}_{3}\mathrm{C}$ are good agreement experimental measurements of carburization rate ferritic steels. In our proposed mechanisms, C migrates by jumps ...

We report a self-recognition phenomenon based on an assembly process in a homogeneous dilute aqueous solution of two nano-scaled, spherical polyprotic metal oxide-based macroions (neutral species in crystals), also called Keplerates of the type [(linker)₃₀(pentagon)₁₂]≡[{M(H₂O)}₃₀{(Mo)Mo₅}₁₂] where M is Fe(III) or Cr(III). Upon deprotonation of the neutral species, the resulting macroions assem...
