A small set of unsymmetrically substituted acene derivatives containing either aniline or dithiocarbamate moieties was synthesized. A stepwise, one-pot procedure was used to transform appropriate acenequinones to aniline-linked acenes in one step with moderate yields. A heretofore-unreported carbon disulfide activation process involving the formation of a trialkylammonium dithiocarbamate interm...

Aluminum alloy sliding components are widely used in internal combustion engines. However, aluminum easily adheres to the countersurface, resulting high friction. Hence, laser irradiation was oxidize surface and promote tribofilm formation using molybdenum dithiocarbamate zinc dialkyldithiophosphate (ZnDTP). This study investigated reduce friction between steel balls disks fully formulated engi...

background: technetium-99m radioisotope is the backbone of any nuclear medicine institute. this radioisotope is acquired by the elution of molybdenum-99/technetium-99m generator which emits 141 kev gamma ray and having 6.04 hour half-life. occasionally the contents of molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. this...

Diabetes is often associated with psychological complications such as anxiety. The aim of this study was to evaluate the effects of pyrrolidine dithiocarbamate on anxiety of streptozotocin-induced diabetic mouse using the open field and the elevated plus maze tests. Confirmed diabetic mice (>16.7 mM/l of blood glucose) were treated with pyrrolidine dithiocarbamate or 0.9% saline for 10 w. After...

Solid phase extraction (SPE) techniques have been widely used for the pre-concentration and separation of trace metal ions in aqueous systems prior to their determination. Among the techniques available, the dithiocarbamate solid-phase extraction method is very selective because dithiocarbamate reagents do not react with many metals (alkali, earth alkali and some other metals such as Al and Cr)...

An extremely sensitive pulse polarographic method for the determination of zinc dimethyldithiocarbamate (an agricultural fungicide) and zinc di-n-pentyldithiocarbamate (a petroleum additive), has been developed based on the reaction of their dithiocarbamate moiety with copper(II) perchlorate in acetonitrile medium. Well defined diffusion-controlled peaks are observed at –140 mV and –130 mV (vs ...

1. Male WAG/Cpb inbred rats fed on rations with approximately 1.5 mg copper/kg (deficient), 6.0 mg Cu/kg (adequate) and 25.0 mg Cu/kg (excess) were supplemented with varying amounts of molybdenum (0, 50, 150 and 500 mg/kg diet) and the effect on the Cu concentration of blood, plasma, liver and kidney, the caeruloplasmin activity of plasma and the Mo concentration of liver and kidney were studie...

the molybdenum dicilicide is an intermetallic compound with two allotropies tetragonal ?-mosi2 and hexagonal ?-mosi2.the ?-mosi2 phase is established to 1900 ?c and ?-mosi2 phase from 1900 to 2050 ?c. this material has considerable properties that provide different applications in different industries such as air-space industry and gas turbines. the molybdenum synthesis can be down in various w...

The most recent data on mechanisms of spin trapping of nitric oxide (NO) by iron dithiocarbamate complexes in animal and plant cells and tissues are considered. The rationale is as follows: 1 In the absence of NO in cells and tissues, iron binds primarily to compounds others than dithiocarbamate ligands, e.g., tricarbonic acids. 2. Predominant binding of iron to dithiocarbamate ligands takes pl...
