1. Effect of Push-Pull Ruthenium Complex Adsorption Conformation on the Performance of Dye Sensitized Solar Cells
A new series of tris-(bipyridyl)ruthenium-like complexes based on the 4-tripheylamine-2,2’:6’,2’’-terpyridine (TPA) push-pull ligand was prepared by incorporation of 4-carboxypyridine (cpy), 4,4’-dicarboxi-2,2’-bipyridine (dcbpy) and 4-carboxyterpyridine ligands (ctpy) ligands, in order to adsorb them on TiO2 in different anchoring conformations.

3. NOVOS HÍBRIDOS BASEADOS EM OXIHIDRÓXIDO DE FERRO(III) E NANOPARTÍCULAS DE OURO (AuNPs/FeOOH) COMO CATALISADORES PARA A REDUÇÃO DE POLUENTES ORGÂNICOS AMBIENTAIS
A new δ-FeOOH supported nano-Au catalyst was prepared by a facile method using HAuCl4 as the gold source and NaBH4 as the reducing agent. The samples (denoted as AuNPs/FeOOH) were characterized by means of X-ray diffraction (XRD), UV-vis and infrared spectroscopies and scanning electron microscope (SEM). The obtained characterization data confirmed the form

4. Deposition of Carbon Nanotube Films on Polyamide and Polypropylene Substrates: A Computer Simulation Approach
In this work we study hydroxylated carbon nanotube (CNT) assembly on polyamide (PA) and polypropylene (PP) polymers activated by UV radiation from a theoretical and experimental perspective. Molecular computer simulation was done to understand the stable conformations and bulk properties (molecular dynamics) of the polymers before and after exposure to UV ra

5. Haptic anchoring and human postural control
Several studies have emphasized the contribution of haptic input that results from the use of rigid and non-rigid tools to the postural control system. Experimental protocols such as the light touch and the anchor system are based on individuals' haptic exploration of the environment through direct tactile-kinesthetic contact, or indirectly through rigid or

6. Cartilage reconstruction using self-anchoring implant with functional gradient
This study presents an innovative and original biomaterial designed to substitute for articular cartilage and mimic its mechanical behavior, including elastic cushioning and the characteristics of fiber-reinforced gel. The material was composed of polyurethane and bioglass microfiber 45S5. It was designed to present a tribological surface to the cartilage of

7. Estudos da deposição de filmes de diamante CVD sobre carbeto de tungstênio, com interface controlada de boreto / Studies of the deposition of diamond CVD films on tungsten carbide, boride with interface control
The objective of this work was to obtain adherent diamond films on WC-Co substrate through the hot filament assisted CVD technique, using a boriding process to form an intermediate layer and avoid the diffusion of the cobalt to the substrate surface. The boriding process consists of a reactive thermo diffusion treatment, in which boron atoms are spread in th

8. Construção de sistema que permite a ancoragem de proteína recombinante à superfície celular de levedura. / Construction of a system that allows anchoring of recombinant protein to the cell surface of yeast.
Cell surface display systems have being developed for expression of heterologous proteins anchored to the cell surface of microorganisms. Several applications of these systems have been reported, including employment as whole-cell biocatalysts, development of vaccines and cellular biosorvents. In this work it was developed a system that allows the anchoring

9. Efeitos de superfície nas propriedades térmicas e dinâmicas de filmes de cristais líquidos esméticos. / Surface effects on the thermal and dynamical proprieties of smectic liquid crystal filmes.
The thermal and dynamical properties of free-standing films are strongly dependent on the boundary conditions and the presence of an external field. Using distinct theoretical models and the dynamic light scattering experimental setup, we study the surface and external field effects on the relaxation dynamics, fluctuation-induced interaction energy, and phas

10. Efeitos de superfície nas transições de fases por redução de camadas em filmes de cristal líquido livremente suspensos. / Surface effects in layer-thinning transitions in free-standing liquid crystal films.
Cristais líquidos exibem uma grande variedade de fases que diferem umas das outras por suas propriedades físicas e estruturais. Próximo a uma transição de fase, estes compostos são bastante sensíveis às interações superficiais apresentando fenômenos interfaciais que são extraodinariamente variados e interessantes. A interação entre as surperfí

11. Sistemas químicos integrados via complexos de rênio(I) e rutênio(II) na conversão de energia / Chemical integrated systems via rhenium and ruthenium complexes on energy conversion
The focus of this work is on two chemical integrated systems: dye-sensitized solar cells, Dye-Cells®, and photosensors based on rhenium(I) compounds. Novel ruthenium(II) compounds were synthesized, characterized and investigated as dye-sensitizers. The results of solar cells sensitized by cis-[(H3BCN)2Ru(dcbH2)2], H3BCN- = cyanoborohydride, dcbH2 = acid-4,4

12. Análise por modelagem e dinâmica molecular da interação entre a integrina α6β1 e a laminina 111 humana / Molecular modelling and dynamics analisys of human α6β1 integrin and laminin 111 interaction
The extracelullar matrix (ECM) is formed by an assembly of proteins and glycoproteins which surrounds the cells, in various tissues. The laminin is a glycoprotein localized in the ECM that consists of three polypeptidic chains cross- shaped. It functions by anchoring epithelial cells to basal lamin, through associations with integrins, collagen, elastin and
