Due to their inertness, platinum(IV) complexes are well known potential candidates to improve the pharmacological properties and selective cellular uptake of commonly used platinum(II) anticancer agents. In these 6-coordinate prodrugs, the equatorial nonleaving groups are the only ligands which ...

N/P co-doped carbon nanosheets (NPC) have been prepared by a simply direct pyrolysis method using amino tris(methylene phosphonic acid) (ATMP) as carbon, nitrogen and phosphorus co-sources, and utilized as Pt-free counter electrodes (CEs) for dye-sensitized solar cells (DSSCs). The prepared N/P ...

The co-sensitization of mesoscopic TiO2 anode is a promising solution to wide-spectra dye-sensitized solar cells (DSSCs) with improved power conversion efficiency. Quantum dots are featured with tunable bandgaps, small sizes and high absorption coefficients, therefore they are always combined wi...

Pillar-like mesoporous carbon doped with oxygen and sulfur heteroatoms was obtained through thermal pyrolysis of a zinc-based metal-organic framework, Zn-BTC (BTC = 1,3,5-benzenetricarboxylic acid), followed by acid treatment and sulfurization. The pillar morphology remained after acid etching a...

Phosphorus-doped porous graphene nanosheet with a large specific surface area (1627.8 m2 g−1) was prepared via chemical vapour deposition (CVD) with porous Mg3(PO4)2 as phosphorus (P) source and template, then it was applied as the counter electrode (CE) for dye-sensitized solar cell (DSSC). Due...

The reactions of diphosphorus tetraiodide with phenol and certain aliphatic alcohols, Grignard reagents, and amines have been investigated. Although small quantities of the expected substituted diphosphorus compounds have been detected spectrophotometrically among the products from some of the r...

Anion exchange chromatography has been used to determine the hydrolysis products of diphosphorus tetrachloride and diphosphorus tetraiodide in both acidic and basic solutions.

A number of studies have shown that Layered double hydroxides, LDH, are attractive materials for fabrication of biosensors. However, few studies have addressed the application of LDH modified electrodes for sensing of electroactive anions. In this study, we used synthetic Zn–Al LDH to construct...

The safe management of iodine coming from spent nuclear fuels by storage in deep geological repositories requires durable materials. For this purpose, we have recently developed an iodate-substituted hydroxyapatite (HA-CaI). In the present article, the chemical durability of this material is ass...

A possible strategy for the management of radioactive iodine-129 is to incorporate it under the form of iodate in hydroxyapatite matrices (HA-CaI) intended to be stored in deep geological repositories. To meet disposal requirements, powder materials that were here obtained by a wet-precipitation...

Selective killing of RPE cells in vivo by sodium iodate develops cardinal phenotypes of atrophic age-related macular degeneration. However, the molecular mechanisms are elusive. We tried to search for small cyto-protective molecules against sodium iodate and explore their mechanisms of action. S...

Clinoptilolite nanoparticles (NClin) were Fe(II)-exchanged and used for the modification of carbon paste electrode (Fe(II)-NClin-CPE) in indirect determination of iodate. The voltammetric peak current of Fe(II)/Fe(III) redox system was decreased in the presence of iodate in solution. Sufficient ...

Metal iodates are strong iodine rich oxidizers which can be used in the formulation of biocidal energetic materials. Generally, metal iodates particles were synthesized by chemical precipitation methods with a large size distribution. In this work, we developed a one-step and solvent-free, high ...

Nitrate and radioiodine (129I) contamination is widespread in groundwater underneath the Central Plateau of the Hanford Site. 129I, a byproduct of nuclear fission, is of concern due to a 15.7 million year half-life, and toxicity. The Hanford 200 West Area contains plumes covering 4.3 km2 with av...

Adsorption of iodate (IO3−) from concentrated solutions by LDH materials has been investigated in laboratory scale batch experiments. Very high iodate (IO3−) uptake (close to 100%) was observed in almost all experiments. Adsorption data was compared to the Langmuir and Freundlich adsorption isot...

Nitrate reduction by the fluoride form of green rust modified with copper (GR-F(Cu)) was investigated using a batch reactor system. The extent of nitrate reduction was measured by measuring the increase in concentration of ammonia, which is the final product of nitrate reduction by GR. This appr...

A new series of complexes of cobalt(II) fluoride, nickel(II) fluoride, copper(II) fluoride and zinc(II) fluoride with imidazole were synthesized and characterized by elemental analysis, molar conductance, magnetic moments, IR and electronic absorption measurements. Based on elemental and spectra...

It is necessary to study the mechanism of resistance to heavy metals in microbiological processes. In this study, Ochrobactrum MT180101 was used as the microbial source of an membrane bioreactor to investigate its degradation efficiency for electroplating wastewater and the copper-resistant mech...

We have synthesized and characterized two new cobalt(II) complexes: difluoridotetrakis(3-hydroxypyridine-κN)cobalt(II), [CoF2(C5H5NO)4] (1) and hexa(2-pyridone-κO)cobalt(II) tetrachloridocobaltate(II), [Co(C5H5NO)6][CoCl4] (2). The complexes were prepared by solvothermal synthesis. A methanol ...

Substitution of inorganic ions into β-tricalcium phosphate (β-TCP) is a well-known approach for facilitating biological functions of bioceramics. However, the dissolution mechanism of those β-TCPs is still under intensive debates. In the present study, the effect of copper substitution into β...
