Micellar and vesicular nanoassemblies of triazole-based amphiphilic probes triggered by mercury(II) ions in a 100% aqueous medium

22-10-2014 | Inhye Kim; Na-Eun Lee; Yoo-Jeong Jeong; Young-Ho Chung; Byoung-Ki Cho; Eunji Lee, Chemical Communication, 2014

ABA-type amphiphiles bearing a triazole-based aromatic block were easily synthesized using click chemistry, which act as fluorescent turn-off Hg2+–chemoprobes in an aqueous solution. Interestingly, the metal-binding process of amphiphiles induced nanoassemblies even below the CMCs, and the ...

The Environmental Costs and Benefits of Fracking

17-10-2014 | Robert B. Jackson; Avner Vengosh; J. William Carey; Richard J. Davies; Thomas H. Darrah; Francis O'Sullivan; Gabriel ..., Annual Review of Environment and Resources, 2014

Unconventional oil and natural gas extraction enabled by horizontal drilling and hydraulic fracturing (fracking) is driving an economic boom, with consequences described from “revolutionary” to “disastrous.” Reality lies somewhere in between. Unconventional energy generates income and, done well, ...

Solid–ionic liquid interfaces: pore filling revisited

15-10-2014 | M. T. Heinze; J. C. Zill; J. Matysik; W. D. Einicke; R. Gläser; A. Stark, Physical Chemistry Chemical Physics, 2014

The properties of ionic liquids on ordered and non-ordered mesoporous silicas (silica gel, MCM-41, SBA-15) were studied by nitrogen sorption, mercury intrusion and thermogravimetric analyses, as well as 129Xe-NMR spectroscopy. The ionic liquids investigated are based on the ...

Simple, Direct and Simultaneous Stripping Voltammetric Determination of Lead and Copper in Gasoline Using an In Situ Mercury Film Electrode

09-10-2014 | C. Martiniano, Lorena; de M.S. Almeida, Joseany; H.R. Cavalcante, Glene; P. Marques, Edmar; C.O. Fonseca, Teresa; L. ..., Current Analytical Chemistry, 2014

Abstract: An improved procedure is presented to determine Pb(II) and Cu(II) in gasoline using a mercury film electrode generated in situ. The method is based on the reduction of the metal ions at adequate potentials on the glassy carbon electrode, in whose optimized microemulsion medium ...

Galvanically replaced Au–Pd nanostructures: study of their enhanced elemental mercury sorption capacity over gold

09-10-2014 | B. Lay; Y. M. Sabri; S. J. Ippolito; S. K. Bhargava, Physical Chemistry Chemical Physics, 2014

In this study, the efficiency of bimetallic (Au–Pd) nanostructures over Au and Pd substrates for elemental mercury (Hg0) vapor sensing and capturing was investigated. The quartz crystal microbalance (QCM) technique was utilized to determine the sorption kinetics and quantity of Hg0 captured by ...

Time-resolved probes and oxidase-based biosensors using terbium(III)–guanosine monophosphate–mercury(II) coordination polymer nanoparticles

08-10-2014 | Min Zhang; Zhi-bei Qu; Chun-Min Han; Ling-Fei Lu; Yan-Yun Li; Tianshu Zhou; Guoyue Shi, Chemical Communication, 2014

A novel lanthanide coordination polymer nanoparticle (LCPN)-based ternary complex was synthesized via the self-assembly of a terbium ion (Tb3+) with a nucleotide (GMP) and a mercury ion (Hg2+) in aqueous solution. The as-prepared LCPN-based ternary complex (Tb–GMP–Hg) can be applied to the ...

Reversible photoswitching specifically responds to mercury(II) ions: the gated photochromism of bis(dithiazole)ethene

07-10-2014 | Yue Wu; Weihong Zhu; Wei Wan; Yongshu Xie; He Tian; Alexander Li, Chemical Communication, 2014

While a dithiazole-containing molecular photoswitch undergoes photochemical interconversion, Hg(II) ions and EDTA “lock-and-unlock” the switch, respectively, and thus regulate its photoswitching processes on and off regardless of the light stimulation. During the photoswitching processes, ...
