The solvothermal reaction of elemental zinc with sulfur in ethylenediamine (en) as solvent yields [ZnS-0.5(NH2CH2CH2NH2)], 1, an unprecedented ethylenediamine pillared ZnS layered compound, containing two dimensional (2-D) boat-type 6-membered rings, which was characterized by ab initio structure solution from powder diffraction data (SDPD).

antioxidant activity of peucedanum pastinacifolium boiss. & hausskn aerial part hydroalcoholic extract (hae) and polyphenolic extract (ppe) as well as their total phenolic and flavonoid contents were studied. phenolic and flavonoid contents were respectively estimated as gallic acid and quercetin equivalents. the in vitro antioxidant activity of two extracts of p. pastinacifolium were evaluated...

A series of novel 1,4diazepines have been synthesized from β-diketones / β-ketoesters of 4acetylaminobenzene sulphonyl chloride. Desired compounds were prepared by the reaction of novel βdiketone / β-ketoester derivatives of [N4-(4acetylamino) benzene sulphonyl piperazinylN1-1bromopropane] with ethylenediamine to get 1, 4dizapines. All the newly synthesized compounds were characterized with IR ...

Molecular hybrids of TQEN (N,N,N',N'-tetrakis(2-quinolylmethyl)ethylenediamine) and EDTA (ethylenediamine-N,N,N',N'-tetraacetic acid) were examined as fluorescent Zn(2+) sensors. Upon the addition of Zn(2+), N,N-BQENDA (N,N-bis(2-quinolylmethyl)ethylenediamine-N',N'-diacetic acid, 1a) exhibits a 30-fold emission enhancement at 456 nm (λex = 315 nm, ϕZn = 0.018) in buffer (HEPES, pH = 7.5, 100 m...

A bioassay for the possible carcinogenicity of N-(1-naphthyl)ethylenediamine dihydrochloride was conducted using Fischer 344 rats and B6C3F1 mice. N-(1-Naphthyl)ethylenediamine dihydrochloride was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species. Twenty-five rats of each sex and 50 mice of each sex were placed on test as contr...

Two-dimensional Bi₂Se₃ nanosheets with hexagonal shape are synthesized by a solution synthetic route. The Bi₂Se₃ nanosheets are 120 nm in edge width and 7 nm in thickness. The size of the Bi₂Se₃ nanosheets can be controlled by choosing different kinds of reducing agents including hydroxylamine and ethylenediamine. Subsequently, we demonstrate a configuration of two-color all-optical switching b...
