Abstract This paper reviews hydroxyl‐terminal polybutadiene (HTPB) used as liner and binder for composite propellants, applied in rocket motors studied throughout the last decades, emphasizing the recent advances. The contribution aims to show the importance of HTPB in the propellant composition and on the liner coating of the rocket motor, which is in contact with the propellant grain. This paper also shows that many researchers have thoroughly studied several properties of HTPB, which are relevant ...

Rubber blends are important materials in automotive industry, as well as in other sectors. However, there are implications when suitable use of a polymer in an artifact is not made. In the automotive area, for example, the use of an elastomer without the fuel resistance requirement would result in component degradation, potential fuel leakage, and danger of fire. The use of polymer blends may be the solution to this problem. Fourier transform infrared spectroscopy (FT-IR) can be used for the knowledge ...

Potential mechanisms involved in neural differentiation of adipocyte derived stem cells (ADSCs) are still unclear. In the present study, extracellular vesicles (EVs) were tested as a potential mechanism involved in the neuronal differentiation of stem cells. In order to address this, ADSCs and neurons (BRC) were established in primary culture and co-culture at three timepoints. Furthermore, we evaluated protein and transcript levels of differentiated ADSCs from the same timepoints, to confirm phenotype ...

When some materials need to be characterized, the hydroxyl number (IOH) determination is especially useful, mainly for those applied in the aerospace field. Usually, this characterization is performed by wet chemistry, using methodologies involving several steps, such as derivatization. This is a time-consuming and costly step. On the other hand, when the analysis is performed by Fourier transform infrared (FT-IR) spectroscopy, the most used region is the medium infrared (MIR) and transmission techniques ...

The performance of Ni-based catalysts synthesized by the combustion method, using different fuel-to-oxidizers ratios (φ), for ethanol conversion reactions was investigated. All catalysts were selective to hydrogen for steam reforming (SR) of ethanol. Regardless of the φ value, all catalysts deactivated during SR of ethanol at 773 K. Scanning electron microscopy and thermogravimetric analyses showed that the loss of activity was due to carbon deposition. However, decreasing φ reduced the amount of ...

Corynebacterium diphtheriae, the aetiologic agent of diphtheria, also represents a global medical challenge because of the existence of invasive strains as causative agents of systemic infections. Although tellurite (TeO32-) is toxic to most microorganisms, TeO32--resistant bacteria, including C. diphtheriae, exist in nature. The presence of TeO32--resistance (TeR) determinants in pathogenic bacteria might provide selective advantages in the natural environment. In the present study, we investigated ...

The partial oxidation of ethanol was investigated over Ru and Pd catalysts supported onto yttria over a wide range of temperatures (473–1073 K). The product distributions obtained over these catalytic systems were correlated with diffuse reflectance infrared spectroscopy analyses (DRIFTS). Results showed that reaction route depended strongly on the type of metal. The decomposition of ethoxy species to CH4 and CO or oxidation to CO2 was promoted by Pd, and the acetaldehyde desorption was predominant ...

This paper studies the effect of space time on the deactivation of a Co/CeO2 catalyst during oxidative steam reforming of ethanol. Increasing space time increased the ethanol conversion and hydrogen selectivity whereas acetaldehyde formation decreased. Both thermogravimetric and scanning electron microscopy analyses of post-reaction samples indicate that higher space times favor the deposition of filamentous carbon. However, the amount of carbon formed passes through a maximum and then decreases ...

A fuel processing system using ethanol as a renewable feedstock is proposed to produce highly pure hydrogen to feed a fuel cell for power generation. Hydrogen production was accomplished through partial oxidation of ethanol over Rh/CeO2 catalyst. The reformate was admitted into a water–gas shift reactor for primary CO clean-up. In this purification stage two different CeO2-supported catalysts were investigated. The results from partial oxidation reaction revealed that hydrogen production is strongly ...

Quantification of elastomer content for the ethylene-propylene diene monomer/polybutadiene blend are seldom subjects in the literature, mainly due to rubber compatibility problems. However, suitable blend contents can lead to desirable properties. Infrared spectroscopy can quantify this type of blend even if some bands overlap, which can be resolved with the proper choice of spectrum obtaining mode and non-overlapping analytical bands. This study evaluates the ethylene-propylene diene monomer/polybutadiene ...

The catalytic performance of Ni/CeGd SOFC anodes prepared by co-precipitation for steam reforming of ethanol at different reaction temperatures was evaluated. The Ni/CeGd SOFC anode calcined at 1073 K exhibited the highest activity and the lowest by-products formation rates during SR at 773 K. The TG and SEM analyses of the used catalysts showed that the deactivation observed for SR at 773 K was associated with the formation of carbon filaments. It was also observed that the increase of reaction ...

A detailed investigation of the effect of Zn on the performance of supported Ni-based catalysts for steam reforming of ethanol is presented in this paper. A Ni/Al2O3 and two ZnO/Al2O3 supported Ni catalysts with different Zn/Al ratio were prepared. For the Ni/Al2O3 and Ni/ZnAl2O4 (Zn/Al = 0.5) catalysts, only metallic Ni particles were identified after reduction. Under ethanol steam reforming conditions, carbon filaments were formed during the reaction, which led to deactivation of the catalyst. It ...
