1. Fine and Coarse Aerosol at Rio de Janeiro prior to the Olympic Games: Chemical Composition and Source Apportionment
During the period from June 2012 to June 2013, the concentrations and chemical composition of PM2.5 and PM2.5-10 (particulate matter with a diameter of 2.5 μm or less and between 2.5 and 10 μm, respectively) were monitored at four sampling points in the Rio de Janeiro metropolitan area, and two of the points were in close proximity to the 2016 Olympic Game

2. Introdução de misturas de GNV e hidrogênio (Hidrano) em veículos convencionais no Brasil e seus impactos econômicos, ambientais e energéticos / Introduction of CNG and hydrogen (HCNG) for conventional vehicles and its economic, environmental and energy impacts
Several strategies have been proposed to introduce hydrogen in the economy specifically in the transport sector in order to reduce environmental impacts of conventional fuels. One of the strategies implies in adding hydrogen to compressed natural gas (HCNG), making use of the existing refueling stations and natural gas fleet. Thus the costs and time for the

3. Detecção de adulteração de combustíveis com sensores poliméricos eletrodepositados e redes neurais artificiais. / Fuel adulteration detection using electrodepositated polymer sensors and artificial neural networks.
A adulteração de combustíveis é uma grande preocupação no Brasil. A agência reguladora nacional (ANP) detecta anualmente de 1 a 3% de adulterações nas amostras coletadas, o que é um índice alto considerando o tamanho do mercado brasileiro. As alternativas de adulteração são vastas e muito dinâmicas, por isso os arranjos de sensores baseados no

4. Estudo de compostos orgânicos voláteis na atmosfera da região metropolitana de Campinas / Study of volatile organic compounds in the atmosphere of metropolitan area of Campinas
This work presents a study of volatile organic compounds (VOC) found in the atmosphere of Metropolitan Area of Campinas (Campinas, SP). The first step was to perform a vehicular emissions inventory of the study area. Vehicular emissions were estimated using emission factors from new vehicles and bottom-up approach, considering different categories of vehicle

7. Verification of diesel fuel lubricity behavior with addition of ethanol. / Verificação do comportamento da lubricidade do óleo diesel veicular com adição de etanol.
A study in the lubricity behavior of blends of anhydrous ethanol in diesel fuel was carried on using the High Frequency Reciprocating Rig method, which is usually employed for predicting the wear that the fuel injection system of a diesel powered vehicle is subjected due to the degree of lubrication provided by the fuel. The addition of anhydrous ethanol to
