Danilo Manzani,João Flávio da Silveira Petruci,Karina Nigoghossian,Arnaldo Alves Cardoso,Sidney José Lima Ribeiro +4 more
TL;DR: The probe fabricated in the study exhibited suitable properties for its application as a temperature sensor and superior performance compared to other Er3+ -based optical thermometers in terms of thermal sensitivity.
Journal ArticleDOI
Use of levoglucosan, potassium, and water-soluble organic carbon to characterize the origins of biomass-burning aerosols

TL;DR: In this article, three chemical species related to biomass burning, levoglucosan, potassium and water-soluble organic carbon (WSOC), were measured in aerosol samples collected in a rural area on the outskirts of the municipality of Ourinhos (Sao Paulo State, Brazil).
Journal ArticleDOI
Influence of sugar cane burning on aerosol soluble ion composition in Southeastern Brazil
TL;DR: In this article, seasonal variability in the major soluble ion composition of atmospheric particulate matter in the principal sugar cane growing region of central Sao Paulo State indicates that pre-harvest burning of sugar cane plants is an important influence on the regional scale aerosol chemistry.
Journal ArticleDOI
Sources of atmospheric acidity in an agricultural-industrial region of São Paulo State, Brazil
TL;DR: In this paper, surface-based measurements of atmospheric formic acid (HCOOH), acetic acid (CH3COOH, sulfur dioxide (SO2), hydrogen chloride (HCl), and nitric acid (HNO3) were made in central Sao Paulo State, Brazil, between April 1999 and March 2000.
Journal ArticleDOI
Analytical chemistry in a liquid film/droplet
TL;DR: In this paper, the measurement of nitrogen dioxide at the parts-perbillion level is described, where two optical fibers placed on opposite sides of and in contact with a liquid film (14-57 μL in volume) supported on a U-shaped wire guide and two tubular conduits.
