The absorption characteristics of Cd(2+) by 10- to 12-day-old soybean plants (Glycine max cv Williams) were investigated with respect to influence of Cd concentration on adsorption to root surfaces, root absorption, transport kinetics and interaction with the nutrient cations Cu(2+), Fe(2+), Mn(2+), and Zn(2+). The fraction of nonexchangeable Cd bound to roots remained relatively constant at 20...

Cadmium (Cd), a widespread cumulative pollutant, is a known human carcinogen, associated with inflammation and tumors. Matrix metalloproteinase-9 (MMP-9) plays a pivotal role in tumor metastasis; however, the mechanisms underlying the MMP-9 expression induced by Cd remain obscure in human endothelial cells. Here, Cd elevated MMP-9 expression in dose- and time-dependent manners in human endothel...

A pyrene-containing single-molecule excimer-emitting compound, 1,8-bis(pyren-2-yl)naphthalene (BPyN), was synthesized. With BPyN as a host emitter, C545T-based green OLEDs were fabricated, exhibiting high efficiencies of 22 lm W(-1), 22 cd A(-1) and 6.2% external quantum efficiency (EQE) at 100 cd m(-2), and 19 lm W(-1), 22 cd A(-1) and 6.2% EQE at 1000 cd m(-2).

The asymmetric unit of the title compound, (C(7)H(18)N(2)O)(2)[Cd(2)Cl(8)], comprises one 4-(2-hy-droxy-eth-yl)-2-methyl-piperazine-1,4-diium dication and a half [Cd(2)Cl(8)](4-) anion. The two Cd atoms are each coordinated by two bridging Cl atoms and three terminal Cl atoms and the [Cd(2)Cl(8)](4-) anion is located on an inversion centre. The crystal structure consists of N-H⋯Cl hydrogen-bond...

BACKGROUND The substitution of Ca(2+) in Ca-hydroxylapatite by toxic Cd(2+) can cause the forming of Cd-hydroxylapatite and is a significant issue in a great variety of research areas, which hence needs an understanding of the essential physicochemical characteristics. Unfortunately, the solubility product and thermodynamic data for Cd-hydroxylapatite in water under a variety of conditions now ...

In the title compound, [CdI(2){(C(6)H(5))(3)PO}(2)], the Cd(II) atom is ligated by two I atoms and two O atoms from two triphenyl-phosphine oxide ligands in a disorted tetra-hedral arrangement. While the O-Cd-I angles vary from 106.67 (7) to 111.23 (7)°, the O-Cd-O angle is 88.60 (10)° and the I-Cd-I angle angle is 125.47 (2)°. The crystal structure is stabilized by van der Waals forces only.

In the title compound, [CdCl(2)(C(5)H(7)N(3)O)(2)], the Cd(II) atom is six-coordinated by two heterocyclic N atoms [Cd-N = 2.261 (2) and 2.286 (2) Å] and two O atoms [Cd-O = 2.624 (2) and 2.692 (2) Å] from two bidentate chelate 2-amino-6-methyl-pyrimidin-4(1H)-one ligands and two chloride ions [Cd-Cl = 2.4674 (6) and 2.4893 (7) Å]. The crystal packing is characterized by an open-framework archi...

The title compound, [Cd(NO(3))(2)(C(11)H(13)N(3))(2)], was synthesized by hydro-thermal reaction of Cd(NO(3))(2) and S-2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole. The Cd atom lies on an inversion centre. The distorted octa-hedral Cd environment contains two planar trans-related N,N-chelating S-2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole ligands in one plane and two monodentate nitrate ligands. N-H⋯O...
