Composting with chitosan and cat litter composite

Date: Dec 15, 2007

Author: David Bradley

The viability of a novel slow-release system for a nitrogen-phosphorus-potassium (NPK) agricultural fertiliser has been tested using atomic absorption spectrometry and shown to have excellent release properties.

Comparison of artificial neural networks with PLS regression for simultaneous determinations by ICP-AES

Date: Dec 1, 2007

Author:

The simultaneous determination of several elements (U, Ta, Mn, Zr and W) by ICP-AES in the presence of spectral interference was performed using chemometrics methods, using a true comparison between artificial neural networks and partial least squares regression.

Garlic protection

Date: Nov 15, 2007

Author: David Bradley

Atomic absorption spectroscopy has been used to analyse the distribution of lead and cadmium in different mouse organs including liver, kidney, spleen, heart, and blood, after treatment with different aqueous concentrations of garlic. The results suggest that garlic could help protect against organ damage caused by these toxic heavy metals.

CZE for the speciation of arsenic in aqueous soil extracts

Date: Nov 1, 2007

Author:

Two separation methods using CZE with UV detection were developed for the determination of the most common inorganic and methylated arsenic species and some phenylarsenic compounds, based on hydrodynamic injection and large-volume sample stacking with polarity switching.

Stop! Atoms

Date: Oct 15, 2007

Author: David Bradley

An "atomic coilgun" that can stop atoms in their tracks using a sequence of pulsed magnetic fields has been developed by US scientists. The device opens up the possibility of slowing and trapping atoms regardless of atomic number, which is not possible with laser trapping that works only for certain atoms.

Lead in raw cow's milk by electrothermal atomic absorption spectrometry

Date: Oct 1, 2007

Author:

Lead in raw cow's milk has been determined by validated electrothermal atomic absorption spectrometry (ETAAS) with Zeeman-effect background correction.

Copper blues and the toxic mouse trap

Date: Sep 15, 2007

Author: David Bradley

Atomic absorption spectroscopy of tissues from a mouse model of Wilson's disease has revealed that asymptomatic carriers are at increased susceptibility to copper overload when exposed to chronically high levels in their diet.

Biomonitoring of heavy metals using Mytilus galloprovincialis in Moroccan coastal waters

Date: Sep 3, 2007

Author:

Heavy metal concentrations of mercury, cadmium, lead, zinc, cooper, nickel, manganese and chromium in Mytilus galloprovincialis were investigated to provide information on pollution of Safi coastal area, since these metals have the highest toxic potential.

The pear necessities

Date: Aug 15, 2007

Author: David Bradley

The nopal cactus, commonly known as the prickly pear reveals itself as an important source of minerals in the diets of people in Mexico and the rest of Latin America, thanks to analyses with atomic spectroscopy and other techniques.

The complementarity of LIBS and Raman microscopy for wall painting pigments analysis

Date: Aug 6, 2007

Author:

Laser-induced breakdown spectroscopy (LIBS) and Raman microscopy were used for the identification of pigments in wall painting. The behavior of pigments was studied after a LIBS analysis, by trying to identify the compounds before and after the laser shot.
