Stainless steels are susceptible to the localized pitting corrosion that leads to a huge loss to our society. Studies in the past decades confirmed that the pitting events generally originate from the local dissolution in MnS inclusions which are more or less ubiquitous in stainless steels. Although a recent study indicated that endogenous MnCr2O4 nano-octahedra within the MnS medium give rise ...

Triazole-linked morpholino ((TL)MO) oligonucleic acids were synthesised using the Cu(I) catalysed (3 + 2) azide-alkyne cycloaddition (CuAAC) reaction. The modified DNA analogues were incorporated into 13-mer sequences via solid phase synthesis. UV melting experiments showed that the (TL)MO modification gives higher Tm values than the corresponding (TL)DNA modification.

The redox-active fac-[Mo(V)(mp)(3)](-) (mp: o-mercaptophenolato) bearing asymmetric O- and S-cation binding sites can bind with several kinds of metal ions such as Na(+), Mn(II), Fe(II), Co(II), Ni(II), and Cu(I). The fac-[Mo(V)(mp)(3)](-) metalloligand coordinates to Na(+) to form the contact ion pair {Na(+)(THF)(3)[fac-Mo(V)(mp)(3)]} (1), while a separated ion pair, n-Bu(4)N[fac-Mo(V)(mp)(3)]...

BACKGROUND Evidence on human semen quality as it relates to exposure to various metals, both essential (e.g., zinc, copper) and nonessential (e.g., cadmium, lead), is inconsistent. Most studies to date used small sample sizes and were unable to account for important covariates. OBJECTIVES Our goal in this study was to assess relationships between exposure to multiple metals at environmental l...

A unique 3D Cu(II) complex based on a molybdate oxide cluster and 5-triazole isophthalic acid was synthesized under hydrothermal condition: {Cu(2)(HL)(2)[Mo(4)O(13)]}·2H(2)O (H(2)L = 5-triazole isophthalic acid) (1). Compound 1 shows a spin canting magnetization behavior, and a definite hysteresis loop with a large coercive field of 6.85 kOe.

Testes from nine male Malin x Santa-Ines rams with an average body weight of 43.1+/-3.53 kg, were used to study the effects of palm kernel cake (PKC) based diet on spermatogenic cells and to assess copper (Cu) levels in liver, testis and plasma in sheep. Animals were divided into three groups and randomly assigned three dietary treatments using restricted randomization of body weight in complet...

20 soil samples collected from the vicinity of the Khash Cement plant, Iran, were analyzed for As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb and Zn using ICP-OES. The results revealed that the metal distribution were in a fluctuating manner considering various distances and direction from the cement facility. However, it was observed that the mean concentration of the soil samples has no special trend wit...
