In situ composite manufacture is an approach to improve interfacial adhesion between matrix and reinforcements, in which reinforcements are synthesized along processing itself. powder metallurgy route, particular, offers alternatives some shortcomings found other techniques. This work aims not only review the state of art on metal composites (MMCs)—including cermets—obtained by metallurgy, but also dissect key aspects related development such materials order establish theoretical criteria...
Lycopene is an apolar, acyclic carotenoid mainly found in tomatoes, tomato products, and lycopene-carrots, Showing a very high quenching rate of reactive singlet oxygen being considered as the with strongest antioxidative effect. Carotenoid (lycopene astaxanthine) containing O/W emulsions two different disperse phase fractions were produced by pressure homogenization. Tween® 20 was used emulsifier xanthane stabilizer.
Upper limb amputations are frequently the result of traumatic events, often associated with car accidents or incidents involving industrial machinery. The development prosthetic technologies is essential to provide physical assistance amputees and offer psychological support. In such circumstances, cosmetic gloves can be utilized improve personal social comfort by enhancing visual characteristics similar those a biological hand. this work, we developed formulations based on natural rubber...
The crystallisation kinetics of magnetite from basalt glass was studied using samples prepared by melting basaltic rocks the Serra Geral Formation, without addition nucleating agent, differential scanning calorimetry under isothermal conditions. temperature maximum nucleation rate for determined as 650 [Formula: see text]C. Upon further heating to 860 text]C, a second phase crystallises, which identified X-ray diffraction pyroxene (augite, Ca(Mg,Fe)Si[Formula: text]O[Formula: text]). best...
This work explores the stabilization effect of a sulfonated tannin (black wattle extract) on water-suspended α-alumina particles. Results showed that first additions lead to particle agglomeration. A minimum 0.5 wt% (relative alumina content) is required cover whole surface. Suspensions regain stability at ca. 1.0 (ca.1 mg tannin/m2 surface area), due high negative ζ-potential (−60 mV, pH = 8.0). Both and hydrodynamic diameter are then close those in electrostatically dispersed Changes ionic...
Resumo Polímeros termoplásticos podem ser utilizados como veículo orgânico (VO) em processos de conformação peças cerâmicas por extrusão. Neste contexto, à base amido surgem uma alternativa sustentável ao emprego das poliolefinas convencionalmente utilizadas na formulação pastas cerâmicas. O passo inicial para o desenvolvimento um feedstock (carga extrudável) é a seleção adequada do sistema polimérico ligante, qual responsável conferir propriedades reológicas adequadas durante processamento....
Abstract Basalt glasses may form glass‐ceramic materials upon a thermal treatment (TT) if the Fe 2 O 3 /FeO ratio is greater than 0.5. In this work, Serra Geral Formation basalt was used to produce different by changing its chemical composition, removing via magnetic separation and adding 20 wt% . Glass‐ceramics were prepared melting at 1500°C, followed crystallization plateau 950°C. This petrurgic TT yields dendritic structures surface crystallization. With increase of iron content, more...
