“…The LIBS technique has been evaluated as an alternative method for the quantification of contaminants, macro/micronutrients, and carbon (C) in soils [7][8][9]. It has been used in investigations of texture, pH, and macro-and micronutrients in fertilizers and soil organominerals [10][11][12]. However, although LIBS has been used for soil analysis, it has not previously been employed to investigate the chemical fractions present in the soil.…”

Soil organic matter (SOM) plays an important role in environmental sustainability, since it is involved in carbon and nutrient cycling. Consequently, it is a key factor to consider in studies concerning global climate change and agronomy.Among the main components of SOM are humic substances (HS), which are divided, according to their solubility, into humic acid (HA), fulvic acid (FA), and humin (HU) fractions. Study of the chemical properties of this organic matter is important for understanding the biogeochemical processes occurring in the soil. The aim of this work was to determine the metals iron (Fe) and aluminum (Al), using flame atomic absorption spectrometry (FAAS) and laser-induced breakdown spectroscopy (LIBS), in order to elucidate the role of organic matter in the transport of these metals in Amazonian soils. The results showed that FA was important for Al, while the HA fraction was more selective towards Fe. The translocations of these metals to deeper profiles in two different soils involved either young and less humified organic matter, or older organic matter with a low degree of humification. Therefore, these two humic fractions were involved in the process of soil podzolization, with FA having a predominant role in the transport of Al, while HA was mainly responsible for the transport of Fe.

We report on the growth and transport properties of single crystalline Sb doped SnO 2 wires grown from chemical vapour deposition. While undoped samples presented semiconducting behaviour, doped ones clearly undergo a transition from an insulating state (dR=dT < 0) to a metallic one (dR=dT > 0) around 130À150 K depending on the doping level. Data analysis in the framework of the metal-to-insulator transition theories allowed us to investigate the underlying physics: electron-electron and electron-phonon interactions were identified as the scattering mechanisms present in the metallic phase, while the conduction mechanism of the semiconducting phase (undoped sample) was characterized by thermal activation and variable range hopping mechanisms.

“…Over the past decades the use of laser-induced breakdown spectroscopy (LIBS) technique has become an attractive tool for the elemental analysis of agricultural samples of various nature and origin. For example, LIBS has been applied successfully as an alternative method to quantify toxic elements, macro and micronutrients and C in soils [1][2][3], and macronutrients such as N, K and P and other relevant elements, including Al, Ca, Mg and Si, in fertilizers [4][5][6][7][8][9]. Further, LIBS was shown to be a fast, suitable and reliable technique for the simultaneous qualitative and quantitative analysis of macro and micronutrients in different plant leaves, and even in disease diagnoses [10][11][12][13][14].…”

A soil, a plant and a fertilizer sample were investigated by double-pulse (DP) laser-induced breakdown spectroscopy (LIBS) in orthogonal beam geometry using a reheating configuration. The DP-LIBS signal enhancement was evaluated with respect to the corresponding single-pulse (SP) LIBS as a function of the interpulse delay at various ablation energies. The maximum signal enhancement measured was 155-fold when low ablation energy (4 mJ) and an interpulse delay of 10 μs were used. At high laser energies (≥16 mJ) and interpulse delay of 0.6 μs, the maximum signal enhancement was up to 3-fold. The effect of excitation energies and interpulse delays on emission line intensities was discussed in the various conditions used. The emission line enhancement measured for ionic lines was always higher than that of atomic lines. Plasma excitation temperature and electron density measured as a function of interpulse delays at various ablation energies were shown to be related to the emission line intensities.
