A solid-contact ion selective electrode for copper(II) using a succinimide derivative as ionophore.

Sensors (Basel, Switzerland)

Tutulea-Anastasiu MD, Wilson D, del Valle M, Schreiner CM, Cretescu I.
PMID: 23549362
Sensors (Basel). 2013 Apr 02;13(4):4367-77. doi: 10.3390/s130404367.

All-solid-state sensors with polyvinyl chloride (PVC)-based membranes using off-the-shelf N-hydroxysuccinimide (NHS) and succinimide (Succ) ionophores were prepared using DOP (dioctyl phthalate) and NPOE (ortho-nitrophenyloctyl ether) as plasticizers. Good responses were obtained when NHS was used. The potentiometric response of...

Gámez F, Hortal AR, Hurtado P, Avilés-Moreno JR, Hamad S, Martínez-Haya B.
PMID: 26346407
Chemphyschem. 2015 Dec 01;16(17):3672-80. doi: 10.1002/cphc.201500477. Epub 2015 Sep 30.

The understanding of supramolecular recognition in room-temperature ionic liquids (RTILs) is key to develop the full potential of these materials. In this work, we provide insights into the selectivity of the binding of alkali metal cations by standard cyclodextrin...

PMID: 25049741
Asian-Australas J Anim Sci. 2013 Nov;26(11):1553-61. doi: 10.5713/ajas.2013.13216.

Forty-eight crossbred heifers (378.1±18 kg) were used in a 56-d feeding trial (four pens per treatment in a randomised complete block design) to evaluate the influence of ionophore supplementation on growth performance, dietary energetics and carcass characteristics in finishing...

Complexometric titrations: new reagents and concepts to overcome old limitations.

The Analyst

Zhai J, Bakker E.
PMID: 27272695
Analyst. 2016 Jul 21;141(14):4252-61. doi: 10.1039/c6an00538a. Epub 2016 Jun 08.

Chelators and end point indicators are the most important parts of complexometric titrations. The most widely used universal chelator ethylenediamine tetraacetic acid (EDTA) and its derivatives can strongly coordinate with different metal ions. Their limited selectivity often requires the...

Squaramide-based tripodal ionophores for potentiometric sulfate-selective sensors with high selectivity.

The Analyst

Liu Y, Qin Y, Jiang D.
PMID: 26076485
Analyst. 2015 Aug 07;140(15):5317-23. doi: 10.1039/c5an00259a.

A class of squaramide-based tripodal molecules was employed as new ionophores for highly sensitive and selective sulfate-selective sensors. Compared with the reported tripodal ionophore with urea, squaramide groups as superior hydrogen bonding donor were introduced into the tripodal structure...

Alum and Rainfall Effects on Ionophores in Runoff from Surface-Applied Broiler Litter.

Journal of environmental quality

Doydora SA, Franklin D, Sun P, Cabrera M, Thompson A, Love-Myers K, Rema J, Calvert V, Pavlostathis SG, Huang CH.
PMID: 26436282
J Environ Qual. 2015 Sep;44(5):1657-66. doi: 10.2134/jeq2015.02.0099.

Polyether ionophores, monensin, and salinomycin are commonly used as antiparasitic drugs in broiler production and may be present in broiler litter (bird excreta plus bedding material). Long-term application of broiler litter to pastures may lead to ionophore contamination of...

Carriers for abscisic acid and indole-3-acetic acid in primary roots: their regional localisation and thermodynamic driving forces.

Planta

Astle MC, Rubery PH.
PMID: 24263945
Planta. 1983 Feb;157(1):53-63. doi: 10.1007/BF00394540.

A carrier for the uptake of abscisic acid (ABA) is present in the tips and elongating zones of primary roots of both leguminous (runner bean, French bean, pea) and non-leguminous (sunflower, maize) seedlings. No ABA carrier was present in...

Tetracyclines, verapamil and nifedipine induce callose deposition at specific cell sites in Riella helicophylla.

Planta

Grotha R.
PMID: 24232763
Planta. 1986 Dec;169(4):546-54. doi: 10.1007/BF00392105.

The Ca(2+) indicator 7-chlorotetracycline has been shown to bind to a pore complex on both outer surfaces of all non-meristematic cells in the unistratose thallus of Riella ('chlorotetracycline-binding surface region'=CSR; Grotha, 1983, Planta 158, 473-481). Prolonged treatment of the...

Synthesis and characterization of new chiral calix[4]arenes.

Enantiomer

Okada Y, Mizutani M, Ishii F, Nishimura J.
PMID: 12108639
Enantiomer. 2002 Mar-Jun;7(2):93-106. doi: 10.1080/10242430212191.

The unique chiral calixarenes were successfully synthesized by the following two methods: the Williamson ether synthesis and a stepwise ether cleavage with a mild Lewis acid. The high regioselectivity is recognized by the latter stepwise method. The ionophores having...
