1. The Effects of pH Values on Functional Mechanisms of Nitrite Anions for Q235 Carbon Steels in 0.01 mol L-1 NaNO2-HCl Solutions
For Q235 carbon steels in 0.01 mol L-1 NaNO2-HCl solutions with different pH values, the effects of pH values on the functional mechanisms of nitrite anions (NO2-) were studied. In the pH 1 and pH 2 solutions, the Q235 steels showed the electrochemical behavior of activation, and uniform corrosion (UC) was the main corrosion type on the Q235 surface. The pre

2. Duas Casas: A Creative-Critical Commentary on Romeo And Juliet
Abstract Adaptations created in pedagogical contexts are creative-critical commentaries which produce concepts about adaptational relations unavailable through traditional academic works. The aim of this article is to describe and analyze the short film Duas casas, a creative-critical commentary on Romeo and Juliet produced in a pedagogical context. After pr

4. Optimal hydrated lime concentration in asphalt binder to improve photo degradation resistance
Abstract The effect of short-term oxidation, evaluated by using a Rolling Thin Film Oven Test, and the effect of weathering aging on the oxidation process of hydrated lime modified asphalts were studied. Hydrated lime (HL) has been known as an additive for asphalt mixtures and is now considered as a binder additive that increases asphalt mixture durability.

5. Hydrolyzed collagen interferes with in vitro photoprotective effectiveness of sunscreens
ABSTRACT The chronological skin aging is a progressive and natural process with genetic and physiological changes. However, ultraviolet (UV) radiation may accelerate the oxidative stress, generating carcinogenesis and photoaging. Natural compounds and their applications are considered a trend in the cosmetic market. The protein-based film-forming compounds p

7. Critical Forces at Fractional Matching Fields in Superconducting Thin Films with Triangular Pinning Lattice
We numerically study the commensurability effects in the critical forces in a type II superconducting thin film with vortices under the influence of a triangular pinning lattice at sub matching fields and zero temperature. The analysis is made applying a transport force in two mutually perpendicular directions and magnetic field perpendicular to the film sur

8. ASSOCIATION OF BRANCHED POLYETHYLENE IMINE WITH SURFACTANTS IN AQUEOUS SOLUTION
Three polymer-surfactant systems comprised of branched polyethylene imine (PEI) with an anionic surfactant (sodium dodecylsulfate; SDS), a cationic surfactant (tetradecyltrimethylammonium bromide; TTAB), and a zwitterionic surfactant (
N -tetradecyl-N ,N -dimethyl-3-ammonio-1-propanesulfonate; SB3-14) were stQuím. Nova. Publicado em: 2015-07

9. Photo-assisted electrochemical copper removal from cyanide solutions using porous TiO2 thin film photo-anodes
TiO2 porous films were prepared on ITO coated glass slides by the sol-gel dip-coating method assisted with Polyethylene glycol (PEG). The films were used as photo-anodes in the photo-assisted electrolytic removal of cuprous ions in cyanide media. These were characterized by SEM, UV-Visible spectroscopy and XRD. The PEG modified films were free of cracks and

10. Espectroscopia ultrarrápida do polímero semicondutor luminescente MEH-PPV com excitação no ultravioleta / Ultrafast spectroscopy of the luminescent semiconducting polymer MEH-PPV with ultraviolet excitation
The optoelectronics industry is currently undergoing a transition period in which inorganic materials are being replaced by organic materials, oligomers and polymers, in the fabrication of some types of devices. However, factors such as low efficiency and low lifetime prevent polymer based devices on entering the market definitely. The solution of these issu

11. Programa de controle da qualidade dosimétrico, validado com auxílio de filme radiocrômico, aplicado à radioterapia estereotáxica / Dosimetric quality assurance with the help of the radiochromic film, applied to stereotactic radiotherapy.
Radiation therapy of brain lesions near critical structures requires a highly accurate location and dose. The accuracy in dose delivery should be accompanied by an accurate quality control in devices involving the practice. The commissioning of the planning system is to ascertain and confirm the calculations performed by the system, but even with all quality

12. Caracterização da resistência à corrosão de ligas inoxidáveis Fe-Mn-Si-Cr-Ni-(Co) com efeito de memória de forma / Characterization of the corrosion resistance of Fe-Mn-Si-Cr-Ni-(Co) Shape memory stainless steels
In this work, the corrosion behavior of three Fe-Mn-Si-Cr-Ni(Co) shape memory stainless steels (SMSS) in aggressive environments was characterized. The electrochemical corrosion behavior in 0.5 M H2SO4 solution was obtained by potentiodynamic polarization, linear polarization, potential decay curves, electrochemical impedance spectroscopy (EIS), and Mott-Sch
