Use of a new enrichment nanosorbent for speciation of mercury by FI-CV-ICP-MS
(2015-07-20)Mercury is one of the most toxic environmental pollutants and its effects on human and ecosystem health are well known. All mercury species are toxic, with organic mercury compounds generally being more toxic than inorganic ... -
LIBS spectroscopy meets the ocean. Chemical analysis of archeological materials in Mediterranean waters
(2015-09-02)After decades of development in laboratories and land operations, chemical analysis of submerged objects is starting to become a reality. While the analysis of water at variable depth has been demonstrated in the past using ... -
Fs-Time Resolved Microscopy as a tool for monitoring laser-matter interaction
(2015-09-03)Femtosecond laser pulses provides the advantage in comparison with longer pulses that there is no interaction between laser and plasma. Moreover, the applied energy is deposited in much less time than nanosecond pulses, ... -
Chemical Fingerprints in an Underwater Archaeological Shipwreck using a Remote Laser-Induced Breakdown Spectroscopy System
(2015-09-04)Nowadays, one of the most important areas of interest in archeology is the characterization of the submersed cultural heritage. Mediterranean Sea is rich in archaeological findings due to storms, accidents and naval ... -

(2015-09-10)Nowadays, one of the most important areas of interest in archeology is the characterization of the submersed cultural heritage. Mediterranean Sea is rich in archaeological findings due to storms, accidents and naval battles ... -
How to teach chemistry? Is Chemistry a new universal language
(2015-09-24)Chemistry has been developed greatly throughout the 20th century. Chemistry is included in the curriculum of elementary and secondary education. In general, students are not interested in science, and because ... -
Temporal evolution of surfaces on materials after femtosecond laser irradiation: The earliest stages (Oral presentation)
(2015-10-26)Ablation using femtosecond lasers exhibits significant differences in comparison with the nanosecond timescales. Ultrashort laser-matter interaction provides the observation of different phenomena as there is neither ... -
Development of a new method for preconcentration, chemical vapour generation and determination of metal ions by ICP OES in environmental samples using magnetic nanoparticles
(2015-12-21)Silica-coated magnetic nanoparticles (MNP SCMNPs) modified with [1,5-bis (2-pyridyl)-3-sulphophenyl methylene] thiocarbonohydrazide were synthesized by a sol-gel method. These magnetic nanoparticles (PSTHmnp) were employed ... -
Optimization of the synthesis of functionalized magnetic nanoparticles and their characterization
(2015-12-21)Magnetic nanoparticles (MNPs), a new kind of nanometer-sized material, are widely used in the fields of biotechnology and biomedicine. These particles are superparamagnetic, which means that they are attracted to a magnetic ... -
