Antioxidant activity of protocatechuates evaluated by DPPH, ORAC, and CAT methods.

Food Chem. 194 , 749-57, (2015)

Hibiscus sabdariffa L. is a worldwide consumed plant, principally after infusion of its dried sepals and calyces, which are usually discarded. Nevertheless, they represent a potential source of natural bioactive compounds, e.g. polyphenols, which could add va...

A simple method for the determination of organochlorine pollutants and the enantiomers in oil seeds based on matrix solid-phase dispersion.

Food Chem. 194 , 319-24, (2015)

A simple, rapid and effective method was developed based on matrix solid-phase dispersion (MSPD) for the determination of organochlorine pollutants including sixteen organochlorine pesticides (OCPs) and seven polychlorinated biphenyls (PCBs) in oil seeds (pea...

Preliminary study on brominated dioxins/furans and hydroxylated/methoxylated PBDEs in Baltic cod (Gadus morhua) liver. Comparison to the levels of analogue chlorinated co-occurring pollutants.

Mar. Pollut. Bull. 96 , 165-75, (2015)

Low pg levels of PBDD/Fs in 0.8-38.9 pg g(-1) (fat) range (mean 14.2 pg g(-1)) observed in the tested cod liver samples were significantly lower than levels of their chlorinated analogues (25.1-95.9 range, 37.7 mean pg g(-1) fat). Brominated furans dominated ...

Fluoride adsorption properties of three modified forms of activated alumina in drinking water.

J. Water Health 12(4) , 715-21, (2014)

The study describes the removal of fluoride from drinking water using activated alumina (AA). AA was modified with H2SO4, FeCl3 and a combination of the two to enhance fluoride adsorption. The AA adsorbents were characterized using Brunauer-Emmett-Teller surf...

Carbon Nanotube-Based Supercapacitors with Excellent ac Line Filtering and Rate Capability via Improved Interfacial Impedance.

ACS Nano 9 , 7248-55, (2015)

We report the fabrication of high-performance, self-standing composite sp(2)-carbon supercapacitor electrodes using single-walled carbon nanotubes (CNTs) as conductive binder. The 3-D mesoporous mesh architecture of CNT-based composite electrodes grants unimp...

Tungsten carbide nanotubes supported platinum nanoparticles as a potential sensing platform for oxalic acid.

Anal. Chem. 86(15) , 7849-57, (2014)

Supported tungsten carbide is an efficient and vital nanomaterial for the development of high-performance, sensitive, and selective electrochemical sensors. In this work, tungsten carbide with tube-like nanostructures (WC NTs) supported platinum nanoparticles...

Nanocomposites with functionalised polysaccharide nanocrystals through aqueous free radical polymerisation promoted by ozonolysis.

Carbohydr. Polym. 135 , 256-66, (2015)

Cellulose nanocrystals (CNC) and starch nanocrystals (SNC) were grafted by ozone-initiated free-radical polymerisation of styrene in a heterogeneous medium. Surface functionalisation was confirmed by infrared spectroscopy, contact angle measurements, and ther...

Occurrence, profiles, and ecological risks of polybrominated diphenyl ethers (PBDEs) in river sediments of Shanghai, China.

Chemosphere 133 , 22-30, (2015)

Fifty-two PBDE congeners in river sediments from Shanghai were analyzed in the present study. The concentrations of Σ51PBDEs (defined as the sum of 51 BDE congeners except BDE209) and BDE209 ranged from 0.231 to 119 ng g(-1) and from nd to 189 ng g(-1), respe...

A dendrimer-like hyper branched chitosan beads toward fluoride adsorption from water.

Int. J. Biol. Macromol. 78 , 280-6, (2015)

The present study reports a novel approach for the preparation of polyamidoamine grafted chitosan beads (PAAGCB) via Michael addition followed by protonation of PAAGCB to get protonated PAAGCB (H(+)-PAAGCB). Various metal ions viz., Al(3+), Ce(3+), La(3+) and...

Assessment of two extraction methods to determine pesticides in soils, sediments and sludges. Application to the Túria River Basin.

J. Chromatogr. A. 1378 , 19-31, (2015)

Pressurized liquid extraction (PLE) and Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction methods were optimized for the simultaneous determination of 50 pesticides in sediment, soils and sewage sludge. For QuEChERS development, several buf...
