1. APCI(+)FT-ICR MS Analysis of Hydrocarbons Using Isooctane as Ionizing Reagent - A Comparison with HTGC-FID, GC×GC-MS and NMR
Hydrocarbons present in saturated fractions of crude oils can be assessed by atmospheric pressure chemical ionization (APCI) using small hydrocarbons as ionizing reagents in a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS). In this work, five paraffin standards of different average molar mass distributions (Mw) were easily ionized by

2. AVALIAÇÃO DE CARACTERÍSTICAS DE BIODIESEIS DE FONTES ALTERNATIVAS SUBMETIDOS A CONDIÇÕES DE ARMAZENAGEM DIFERENCIADA
Biodiesel is an alternative fuel obtained from different biomass sources and processes. Nowadays, this biofuel has gained importance due to environmental concerns and rising energy demand. In the biodiesel production chain, stability is a critical issue, as it is linked to the maintenance of its original properties. This work performed a study evaluating the

3. Effect of treatment with adsorbent resin on the volatile profile and physicochemical characteristics of clarified cashew apple juice
Increased preference for healthy and functional foods could be an opportunity to increase the consumption of clarified cashew apple juice. Given its level of fructose, glucose, and vitamin C, it can be used as a base in blends. However, its characteristic odor can interfere with the acceptance of these formulations, especially by consumers who are not famili

4. Desenvolvimento e validação de metodo para determinação do perfil graxo do biodiesel de tungue e blendas com soja empregando GC-MS / Development and validation of method for the determination of fatty acids methyl esters contents in tung biodiesel and Blends with soybean using GC-MS
No Brasil o biodiesel é utilizado em misturas com óleo diesel em proporções de 5%, sem que haja modificações nos motores. Com o intuito de diversificar a utilização de oleaginosas não comestíveis no ramo dos biocombustíveis, e ainda vincular a produção com agricultura sustentável, uma alternativa para o RS é a utilização do óleo de tungue p

5. Síntese de insumos químicos a partir de biodiesel produzido pela transesterificação de gordura animal / Synthesis of intermediary chemicals produced from biodiesel by animal fat
Due to technical and economic reasons, the biodiesel production from animal fat, to be used as biofuel, is disadvantageous when compared to some processes that utilize raw materials from vegetables origin. However, biodiesel derived from animal fat has chemical characteristics that allow its use as an input for a wide range of products with high added value.

6. Poli(oxido de etileno-co-epicloridrina) : degradação foto-oxidativa e termica, e blenda com polipropileno
Polymers derived from ethylene oxide and epichlorohydrin, like poly(epichlorohydrin-co-ethylene oxide) elastomer, are studied as polymer electrolyte for application in photo-electrochemical devices. These materiaIs present the ability to form complexes with alkali salts, presenting high ionic conductivity. In these devices the conversion of the solar energy
