The determination of gases in situ is a challenge for analytical chemistry. This occurs because there is not always power available for running equipment, or because equipments are heavy or large and difficult to handle in the field. One possible solution is the development of miniaturized equipment, both for sampling and determination steps running on battery. Under the analytical aspect…
The transport, dispersion and deposition of chemical species present in the atmosphere are integral to biogeochemical cycling. Increased emissions to the atmosphere resulting from intensified anthropogenic activities can significantly increase the dispersion of material throughout the environment, and therefore affect these cycles, although impacts can be seen to be beneficial or detrimen…
The project has as objective the request of financial fund for the researcher visitor Andrew George Allen. The researcher should be at the Department of Analytical Chemistry, IQ UNESP Araraquara for the period of one year. His specialty is atmospheric chemistry and he will collaborate and to participate in projects in program of researches to be undertaken at the Institute of Chemistry un…

This proposal seeks to develop a method to provide rapid, in situ data on labile phosphate levels in the soil. Knowledge about the availability of macronutrients in the soil is crucial for farmers to manage the use of fertilizers efficiently. Lack of nutrients can result in low agricultural productivity, and excess can cause economic losses and environmental impacts. The project proposal …
Sugarcane plays a prominent role in Brazil's current economy and has growth projections for the coming years mainly due to the use of biofuel ethanol as an alternative energy source. However, a relevant problem regarding the production of ethanol refers to the possible massive increase in the emissions of reactive nitrogen compounds, such as NH3, NO and NO2 to the atmosphere, due to the u…
Within the gaseous pollutant compounds, hydrogen sulfide and its derivatives -such as reduced sulfur compounds (RSC) - play an important role in environmental issues mainly due to their high toxicity, reactivity and corrosive proprieties. Several agencies established limits to emission of H2S in air, ranging from ppm to low ppb. In order to enable the monitoring of hydrogen sulfide in air…

This is a request for a Research Abroad (BEPE) to be developed in collaboration with Prof. Dr. Francisco Javier Pena Pereira; University of Vigo Spain. The initial part of the IC project proposal, which was developing a method for determining phosphate using digital images of the reaction product between phosphate and the reagent, has already been well resolved. The second part, extractin…
Organic nitrates, including peroxy nitrates (RO2NO2) and alkyl nitrates (RONO2), are formed in the atmosphere by the reaction of NOx with oxidation products of volatile organic compounds (VOCs). They comprise up to 20% of all oxidized forms of nitrogen (NOz) and, once formed, can be transported by the winds, undergo chemistry, be incorporated into aerosol or be deposited to the Earth's su…
The aim of this project is the development of a portable and miniaturized platform to be applied in the in situ determination of a single or multi compounds in gaseous matrices. Gaseous samples will be collected using specific reagents and/or sorbents impregnated on solids into a reduced dimensions preconcentrator (i.e pipette-tip), eluted and then detected directly in a microfluidic pape…
The aim of this project is pursue studies using of a new generation of compact gas cells, i.e., so-called substrate-integrated hollow waveguides (iHWGs) that are uniquely available at the Institute of Analytical and Bioanalytical Chemistry, University of Ulm, Germany combined with a compact Fourier transform infrared (FTIR) spectrometer for advanced gas sensing of H2S and O3. The detectio…
