1. NEW APPROACHES TO INTERACTIONS DATA ANALYSIS AT SOLID/SOLUTION INTERFACE. / NOVAS ABORDAGENS PARA ANÁLISE DE DADOS DE INTERAÇÕES EM INTERFACES SÓLIDO/SOLUÇÃO.
Nesse trabalho, realizaram-se abordagens inovadoras sobre a análise de dados de sorção em interfaces sólido/solução. Avaliaram-se dados de equilíbrio da sorção do corante amarelo remazol em sílica-aminopropil. Os melhores ajustes foram obtidos utilizando-se os modelos de equilíbrio químico de Langmuir, Langmuir-Freundlich e Sips. Muitas abordagen

2. Microscopical study of nanometric particles adhesion / Estudo microscopico de adesão de particulas nanometricas
The adhesion of nanometric phases is a topic of increasing scientific interest due to its importance for the production and properties of new nanostructured materials. This study explores the following hypothesis: immiscible and wettable particles carrying charges with same signal can adhere provided that they are mixed in aqueous dispersion and dried out. T

3. Estudo da interação da peroxidase de raiz forte em interfaces nanoestruturadas / Study of horseradish peroxidase interaction in nanostructured interfaces
A study has been performed on the interaction of the enzyme horseradish peroxidase (HRP) in nanostructured interfaces and their possible application in biosensors for hydrogen peroxide. The nanostructured films were obtained with the Langmuir, Langmuir-Blodgett (LB) and layer-by-layer (LbL) methods. The interaction between HRP and species at interfaces was i

4. Estudos SERS (Surface-Enhanced Raman Scattering) em meio de Líquido Iônico BMIPF6 usando eletrodo de prata. / Estudos SERS (Surface-Enhanced Raman Scattering) em meio de Líquido Iônico BMIPF6 usando eletrodo de prata.
Room Temperature Ionic Liquids (RTIL) has had increasingly application in different areas of the Chemistry, due to its advantageous physical-chemical properties in relation to other conventional solvents. BMI cation derived RTILs got relevance due its singular physical-chemical properties, like a good electric conductivity and a wide electrochemical window.

5. ProduÃÃo de heterojunÃÃes de polianilina/silÃcio e nanofibras de polianilina para aplicaÃÃes em dispositivos hÃbridos
In this work we develop the methodology for the synthesis and fabrication of Polyaniline (PANI) â Silicon (Si) heterojunctions, with great potential for technological applications as sensors in different areas such as optics, ionizing radiation and gas detection. Besides, we were able to implement the electrospinnin technique with the goal of producing poly

6. Bases para uma metodologia de apoio à decisão para serviços de educação e saúde sob a ótica dos transportes / Bases for a decision support methodology for education and health services from a transportation perspective
One of the main problems faced by brazilian cities is the lack of adequate methodologies for the implementation and rational use of public service facilities (such as schools and health care centers). That was the starting point in the definition of the main objective of the present work, which is the development of a spatial analysis tool for seeking an opt

7. Bacteriophage Inactivation at the Air-Water-Solid Interface in Dynamic Batch Systems
Bacteriophages have been widely used as surrogates for human enteric viruses in many studies on virus transport and fate. In this investigation, the fates of three bacteriophages, MS2, R17, and φX174, were studied in a series of dynamic batch experiments. Both MS2 and R17 readily underwent inactivation in batch experiments where solutions of each phage were

8. Polymeric amphiphiles at solid-fluid interfaces: Forces between layers of adsorbed block copolymers
Block copolymers are macromolecular amphiphiles and as such have a wide variety of interesting interfacial behavior. We present here a case of block copolymer adsorption from solution studied by the direct measurement of forces between two adsorbed layers. The case is polystyrene (PS)-poly(2-vinylpyridine) (PVP) adsorbed on mica from toluene. Under these cir

9. Pb(II) distributions at biofilm–metal oxide interfaces
The distribution of aqueous Pb(II) sorbed at the interface between Burkholderia cepacia biofilms and hematite (α-Fe2O3) or corundum (α-Al2O3) surfaces has been probed by using an application of the long-period x-ray standing wave technique. Attached bacteria and adsorbed organic matter may interfere with sorption processes on metal oxide surfaces by changi

10. A novel approach in the assessment of polymeric film formation and film adhesion on different pharmaceutical solid substrates
The purpose of this study was to evaluate the nature of film formation on tablets with different compositions, using confocal laser scanning microscopy (CLSM), and to measure film adhesion via the application of a novel “magnet probe test”. Three excipients, microcrystalline cellulose (MCC), spray-dried lactose monohydrate, and dibasic calcium phosphate
