2. Semicondutores heteroestruturados: uma abordagem sobre os principais desafios para a obtenção e aplicação em processos fotoquímicos ambientais e energéticos
Heterostructured semiconductors are materials with unique features formed by combination of two or more semiconductors with suitable interface between them. The study of the heterostructures aim the development of physico-chemical and photocatalytic properties higher than their isolated phases, which makes it possible to obtain higher efficiency and lower co

3. Post-treatment of landfill leachate using rice husk ash as adsorbent medium
Resumo O aterro sanitário é o método mais geral de disposição de resíduos sólidos urbanos. Porém, no processo de degradação da matéria orgânica é produzido um líquido de coloração escura de alto potencial poluente sendo necessário tratamento adequado antes de seu lançamento nos corpos de água. Diversas tecnologias podem ser utilizadas no t

4. Síntese de óxidos mistos AMn2O4 (A=Co, Cu e Ni) preparados por autocombustão para controle de emissões de compostos orgânicos voláteis
RESUMO Os compostos orgânicos voláteis (COVs) são substâncias que possuem elevada pressão de vapor e baixa solubilidade em água e são reconhecidos por serem um dos maiores responsáveis pela poluição atmosférica, tanto por sua natureza tóxica quanto por serem os precursores do ozônio e do smog fotoquímico. O objetivo deste trabalho foi sintetiza

5. Physico-chemical characterization of centrifuged sludge from the Tamanduá water treatment plant (Foz do Iguaçu, PR)
ABSTRACT The water treatment process generates a residue called water treatment plant (WTP) sludge, which needs to be correctly characterized to ensure appropriate disposal or reuse. This study aimed to characterize the centrifuged sludge produced at the Tamanduá WTP, Iguaçu Falls City, Brazil, and considered opportunities for its reuse in the production o

6. Does the landscape surrounding streams affect the occurrence of freshwater crabs? A case study of the genus Aegla (Crustacea: Decapoda: Anomura) in subtropical basins
ABSTRACT Changes in the landscape where watersheds are located may affect the stream biota in different ways. In order to explore this idea, we collected freshwater crabs of the genus Aegla Leach, 1820 in subtropical region of southern Brazil. We also measured a number of landscape features and physico-chemical variables in the collection streams and surroun

7. Strategy for Treating a Landfill Leachate by Integration of Physico-Chemical and Photo-Fenton Processes
This study reports a protocol for the treatment of a sanitary landfill leachate through integration between a stage of coagulation-flocculation, a step of filtration of the resulting suspension, and application of the photo-Fenton process using a ferrioxalate complex and solar irradiation. The best results for turbidity removal by coagulation-flocculation we

9. Filamentous fungi isolated from Brazilian semiarid tolerant to metallurgical industry wastes: an ex situ evaluation
The purpose of this study was to assess the impact of metallurgical industry wastes on the semiarid soil microbiota using physico-chemical and microbiological parameters, highlighting the filamentous fungi assembly. Soil samples were collected in an area of industrial waste deposit contaminated with lead and mixed with natural soil (control soil) in seven di

10. CHARACTERIZATION AND EVALUATION OF INTERACTION BETWEEN SPECIES AND METAL HUMIC SUBSTANCES OF PEAT: an alternative for remediation of soil and surface water in the arid region of Sergipe. / CARACTERIZAÇÃO E AVALIAÇÃO DA INTERAÇÃO ENTRE ESPÉCIES METÁLICAS E SUBSTÂNCIAS HÚMICAS DE TURFA: uma alternativa para remediação de solos e águas superficiais na região do agreste sergipano.
This study aimed to understand the interactions between humic substances extracted from peat and metallic species, of the National Park of Itabaiana - SE, seeking a further application in the remediation of soil, surface water contaminated by agricultural activities. We collected samples of soil, fertilizer and peat and characterized by the organic matter co

11. Estudo morfológico e hidroquímico de pequenas depressões na Nhecolândia, Pantanal, MS / Morphological and hydrochemical study of small depressions in Nhecolândia, Pantanal, MS
The southern part of the Taquari alluvial fan, called Nhecolândia, is a sub-region of the Pantanal of Mato-Grosso exhibiting a complex of round shape lakes, draining fields, forested sandy areas, small watercourses and small depressions. Former studies have shown that the sub-superficial water fluxes depend on the intensity of the flood and on the presence

12. Análise de simulantes para produtos ácidos acondicionados em embalagens metálicas / Analysis of simulants to acidic products conditioned in meal package
Tin-plate cans represent most of the cans for canned food. Since they are not inert, during the storage period, interaction occurs with the product and metal dissolution can occur, especially when it is acid food. To minimize this interaction it is used organic coatings, and epoxy-phenolic resin is the the most used. As the foods are complex biochemical syst
