A simple and efficient method using reduced amounts of solvents for the determination polycyclic aromatic sulfur heterocycles (PASHs) in aqueous matrices from a lagoon leachate solid waste petrochemical industry is proposed. The target analytes were previously concentrated disposable pipette extraction (DPX) technique applying gas chromatography-mass spectrometry (GC-MS) analysis. In this innov...
The self-assembly of rigid inorganic cyclophanes comprising cis bridging metal centers connected by aromatic edges has emerged as a promising new area within the realm of hostguest chemistry.1-5 By utilizing the power and simplicity of molecular self-assembly which enables components to arrange themselves into square host cavities, chemists have synthesized a large number of new species with re...
The pH-induced conformational transition in the CuA domain of subunit II of cytochrome oxidase of Paracoccus denitrificans (PdII) has been investigated using various spectroscopic and stopped-flow kinetic methods. UV-visible absorption and circular dichroism studies showed that an increase in pH from 6 to 10 leads to a conformation change with pK(a) = 8.2 associated with the CuA site of the pro...
For the first time oxidative quenching of OsP2N4 chromophores by reactive PtII or PdII sites containing cis, trans, cis-1,2,3,4-tetrakis(diphenylphosphino)cyclobutane (dppcb) is directly observed despite the presence of a saturated cyclobutane backbone "bridge". This dramatic effect is measured as a sudden temperature-dependent onset of a reduction in phosphorescence lifetime in [Os(bpy)2(dppcb...
ژنوم میتوکندریایی شامل ?? ژن کد کنندهء پروتئین است. بسیاری از این ژن ها زنجیرهء انتقال را کد می کنند.ژن 5nd-mt یکی از 13 ژن کد کننده پروتئین است، که زنجیره انتقال الکترون را کد می کند. و جایگاه آن در(i complex)است. ژن 5nd-mt دستورالعمل برای ساختن یک پروتئین به نام nadh دهیدروژناز5 را فراهم می کند. این پروتئین بخشی از یک مجــتمع آنزیم های بزرگ شناخــــته شده با عنوان (i complex)است که در میتوک...
A kinetically inert, reversible coordination polymer (3) was obtained through complexation of dicyclohexylphosphine telechelic poly(tetrahydrofuran) with palladium(II) dichloride. This coordination polymer is unreactive towards palladium(II) dichloride bis(1-diphenylphosphino)dodecane (4), because ligand dissociation in the coordination polymer is slow. However, upon ultrasonication of solution...
