• Lead-based perovskites (PbTiO 3 , PbZrO ) are shown as anodes for secondary batteries. Charge storage in occurs by irreversible conversion (Pb II to Pb 0 followed reversible (de)alloying reaction. TEM confirms the reversibility of reaction with alkali (Li,Na). PbTiO delivers capacity ~300 mAh/g low voltage (~0.5 V) operation both Li-ion and Na-ion introduced novel anode materials non-aqueous ...

A novel reflection-based localized surface plasmon resonance (LSPR) fiber-optic probe has been developed to determine the heavy metal lead ion concentration. Monoclonal antibody as the detecting probe containing massive amino groups to capture Pb(II)-chelate complexes was immobilized onto gold nanoparticle-modified optical fiber (NMAuOF). The optimal immobilizing conditions of monoclonal antibo...

The aim of the present work was to study a simple colorimetric and potentiometric biosensor based on urease inhibition by Pb (II) ions for its estimation in milk samples. Urease immobilized on nylon membrane by hydrosol gel method was used as the biocomponent to demonstrate the metal effect on the enzyme activity using phenol red as the pH indicator. A lower limit detection of 38.6μm was achiev...

The use of the aquatic plant cattail to produce an adsorbent for heavy metals will add value to wetlands. Cattail adsorbents were treated with multi-valent carboxylic acids to facilitate adsorption of Pb(II) from a vanillin solution. Fourier transform infrared (FTIR) spectroscopic analysis confirmed the formation of acid modifications by esterification. While unmodified cattail had a Pb(II) ads...

Transition metal-transporting P1B-type CPx ATPases play crucial roles in mediating metal homeostasis and resistance in all cells. The degree to which N-terminal metal binding domains (MBDs) confer metal specificity to the transporter is unclear. We show that the two MBDs of the Zn/Cd/Pb effluxing pump Anabaena AztA are functionally nonequivalent, but only with respect to zinc resistance. Inacti...

sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. heavy metals can be decreased very effectively with the organic material. in this research, adsorption of pb (ii) onto modified beech sawdust in a batch system was investigated. sawdust was collected from timber mill of qom, iran, and modified with h2so4 and naoh. then, the effects of various paramet...

Poly-o-anisidine Sn(IV) arsenophosphate is a newly synthesized nanocomposite material and has been characterized on the basis of its chemical composition, ion exchange capacity, TGA-DTA, FTIR, X-RAY, SEM, and TEM studies. On the basis of distribution studies, the exchanger was found to be highly selective for lead that is an environmental pollutant. For the detection of lead in water a heteroge...

In the title coordination polymer, [Pb(C(7)H(3)NO(4))](n), the Pb(II) ion is eight-coordinated in a distorted square-anti-prismatic geometry formed by one pyridine N atom and seven carboxyl-ate O atoms from four pyridine-2,3-dicarboxyl-ate (pda) anions. In the pda anion, the dihedral angles between the pyridine ring and carboxyl-ate groups are 19.5 (6) and 73.3 (6)°. The carboxyl-ate groups of ...

Kombucha Scoby is a colony consisted from bacteria, yeast and cellulosic pellicle that present fantastic performances in various fields. Besides anti-toxicity and antimicrobial specifications of Kombucha scoby, this unique colony can be used for waste water treatment and removal of heavy metals. Herein, efficiency of graphene oxide/Fe3O4 nanoparticles (GO/Fe3O4) and Kombucha Scoby in the remova...

In the title compound, [Pb(C(8)H(7)O(2))(2)(C(10)H(8)N(2))], the Pb(II) ion is coordinated by two N atoms from one 2,2'-bipyridine ligand and four O atoms from two 4-methyl-benzoate anions in a distorted pseudo-square-pyramidal environment, considering one of the carboxyl-ate anions as an apical ligand. Pairs of complex mol-ecules related by inversion centers are organized into dimers via pairs...
