An alternative description is provided for the previously reported novel tetranuclear cadmium carbonyl compound, [Cd(CO)3(C6H3Cl)]4. Specifically, consideration of single crystal X-ray diffraction data indicates that the compound is better formulated as the rhenium compound, [Re(CO)3(C4N2H3S)]4.

Cadmium fluoride (CdF 2) is a mostly water-insoluble source of cadmium used in oxygen-sensitive applications, such as the production of metallic alloys. In extremely low concentrations (ppm), this and other fluoride compounds are used in limited medical treatment protocols. Fluoride compounds also have significant uses in synthetic organic chemistry. ...

Cadmium (Cd) is present in many soils and, when entering the food chain, represents a major health threat to humans. Reducing Cd accumulation in plants is complicated by the fact that most known Cd transporters also operate in the transport of essential nutrients such as Zn, Fe, Mn, or Cu. This work summarizes the current knowledge of mechanisms mediating Cd uptake, radial transport, and ...

CdO is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cd2+ is bonded to six equivalent O2- atoms to form a mixture of corner and edge-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Cd–O bond lengths are 2.39 Å. O2- is bonded to six equivalent Cd2+ atoms to form a mixture of corner and edge ...

Cadmium is the second-row transition metal belonging to group 12 of the periodic table, along with Zn and Hg. The element has an atomic number of 48, an atomic mass of 112, one main oxidation state (+2) and eight naturally occurring isotopes (106 Cd, 108 Cd and 110 Cd to 116 Cd), of which 114 Cd, 112 Cd, 111 Cd, 110 Cd and 113 Cd have ...

The effect of cadmium exposition on the structure and mechanical properties of rat incisors

Cadmium (Cd) is a non-essential trace element that is widely distributed in the environment. Both geogenic and anthropogenic sources can elevate Cd concentrations in soils and groundwater, which are important for maintaining healthy supplies of food and safe drinking water. Elevated Cd doses are carcinogenic to humans.

Following cadmium intoxication, endothelial dysfunction at starting of cardiovascular disease (CVD), loss of endothelial cell structure causing cell death, and thrombogenic events may occur. These results support the hypothesis cadmium involvement in cardiovascular disease and myocardial infarction ( 34 ).

Cadmium and cadmium compounds were considered by previous IARC Working Groups in 1972, 1975, 1987, and 1993 (IARC, 1973, 1976, 1987, 1993a). Since that time, new data have become available, these have been incorporated in the Monograph, and taken into consideration in the present evaluation.

Since cadmium is a transition metal with a chemical structure similar to silicon and germanium, it possesses some of the same semi-conducting qualities. By evaporating a compound of cadmium known as cadmium telluride onto glass or plastic, engineers can create a …

Protein turnover is a critical cellular process regulating biochemical pathways and destroying terminally misfolded or damaged proteins. Pca1p, a cadmium exporter in the yeast Saccharomyces cerevisiae, is rapidly degraded by the endoplasmic reticulum-associated degradation (ERAD) system via a cis-acting degron that exists at the 250–350 amino acid region of Pca1p and is …

Cadmium selenide (CdSe) is a binary, primarily ionic compound with a touch of covalent character. It can take three crystalline forms, but the hexagonal wurtzite structure shown is by far the most common. The unit cell is shown in the image; the gray …
