13. Sorghum (Sorghum bicolor) Pellet Production and Characterization
ABSTRACT Pelletization is a technique used to compact biomass, generating a granulated material called pellets, with high energy density. The objectives of this work were to produce pellets made from Sorghum (Sorghum bicolor) residuals and to evaluate its quality. Firstly, the residuals were characterized, followed by the production of the pellets. An experi

14. Production and physicochemical characterization of craft beer with ginger (Zingiber officinale)
Abstract This work aims to produce and to characterize physical-chemically an added craft beer of ginger, as well as its sensorial attributes, due to the new demand for products with innovative flavors. The traditional method of production of beer craft type Pilsen was used, with addition of 2 g L-1 of ginger chips in the maturation stage. The final product

15. Oxidative Dehydration of Glycerol over Molybdenum- and Vanadium-Based Catalysts
Surplus of glycerol production from the biodiesel industry has led to the search for glycerol conversion routes, the most common of which are dehydration and oxidative dehydration. Vanadium and molybdenum oxides were supported on γ-Al2O3 and their properties were analyzed through several characterization techniques, showing that the acidity increases after

16. Characterization of the Ge/Bi2O3 Interfaces
In this article, the properties of the Ge/Bi2O3 interfaces as microwave cavities are reported and discussed. The interface is composed of monoclinic Bi2O3 films grown onto polycrystalline cubic Ge substrate. It is observed that consistent with the theoretical design of the energy band diagram, the experimental current-voltage characteristics of the Yb/Ge/Bi2

20. Production, characterization and toxicology assay of creatine pegylated nanoliposome with polysorbate 80 for brain delivery
ABSTRACT Creatine acts intracellularly as energy buffer and storage, demonstrating protective effects in animal models of neurodegenerative diseases. However, its permeability throught blood-brain barrier (BBB) is reduced. The aim of the present study was developing a carrier to facilitate the delivery of creatine to the central nervous system. Creatine nano

23. Processing and Characterization of PET Composites Reinforced With Geopolymer Concrete Waste
In the present study, poly (ethylene terephthalate)-based composites were produced and characterized. These composites were composed by poly (ethylene terephthalate) (PET) reinforced with geopolymer concrete waste (GCW). Both untreated (U-GCW) and treated with oleic acid (OA) geopolymer concrete waste (T-GCW) were used in the production of the composites. Th
