Biodiesel produced through catalytic transesterification of triglycerides from edible and non-edible oils alcohol is considered an alternative to traditional petro-diesel. The interest in the use alkaline earth metal oxides as heterogeneous basic catalysts has increased due their availability, non-toxicity, capacity be reused, low cost, high concentration surface sites that provide activity. This work a compilation strategies understand effect source, synthesis, thermal treatment MgO, CaO,...
Ni/Al2O3 and NiFe/Al2O3 catalysts were synthesized by incipient wetness impregnation tested for oxidative dehydrogenation (ODH) of ethane to ethylene. The effect Ni loading Fe as a promoter bimetallic characterized X-ray diffraction (XRD), Raman spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS), scanning electron microscopy (SEM), temperature-programmed reduction (H2-TPR). catalyst with 10 wt% 6.6 (NiFe32) displayed the highest ODH activity. XRD results showed...
Abstract This study compared the effects of contralateral eccentric‐only (ECC) and concentric‐/eccentric‐coupled resistance training (CON‐ECC) elbow flexors on immobilized arm. Thirty healthy participants (18‐34 y) were randomly allocated to immobilization only (CTRL; n = 10), ECC (n or CON‐ECC group 10). The non‐dominant arms all (8 h·day −1 ) for 4 weeks, during which performed by dominant (non‐immobilized) arm 3 times a week (3‐6 sets 10 repetitions per session) with an 80%‐120% 60%‐90%...
This paper reports the effects of changes in supported active phase concentration over titania containing mixed oxides catalysts for hydrodeoxygenation (HDO). Mo and CoMo on sol–gel Al2O3–TiO2 (Al/Ti = 2) were synthetized tested HDO phenol a batch reactor at 5.5 MPa, 593 K, 100 ppm S. Characterization results showed that increase loading led to an amount oxide species with octahedral coordination (MoOh), which produced more sites augmented catalytic activity. The study change Co allowed...
Catalytic hydrodeoxygenation (HDO) has been considered as a promising route for biomass revalorization. The development of active and stable materials undertaken over the past decade, precious metals have displayed high activities. Ru exhibited an outstanding performance due to its hydrogenation capacity, among other properties. Rational these catalysts requires understanding contribution properties like acidity, oxophilicity, reducibility, capacity generate oxygen vacancies. However,...
Abstract The temperature effect on VO 2 thin films synthesized by RF sputtering their morphological, optical, electrical properties and activity in the photocatalytic degradation of methylene blue naproxen was studied. Characterization results presented microcrystallinity for treated at 50 100 °C. Nevertheless, untreated 200 °C revealed characteristic peaks monoclinic tetragonal phases. SEM micrographs with elemental mapping showed granular morphology a good oxygen dispersion along film...
Starch is an abundant renewable resource and the raw material for production of a wide range products, many which are obtained by hydrolysis. While hydrolysis starch enzymes acids has been extensively investigated, there scant studies with respect to use solid acid catalysts this purpose. In work, features corn alumina (Al) mixed silica‐alumina (SiAl) oxides have explored, as they widely used due their low cost ease synthesis. To end, native (CS) aqueous dispersion (0.02 g −1 ) such or added...
Abstract The dissolution of chalcopyrite under near ambient conditions represents one the main challenges in copper industry. Thus, various routes have been proposed for treatment, such as use polar organic solvents, and this has shown promising results. In paper, we present a study leaching from concentrate aqueous acidic medium with methanol H 2 O concentrations at 15, 30, 40 °C. results show that nearly complete extraction was attained within 5 h percentages were plotted functions time...
Valdes, O, Inzulza, S, Collao, N, Garcia-Vicencio, Tufano, JJ, Earp, J, Venegas, M, and Peñailillo, L. Eccentric cycling is an alternative to Nordic hamstring exercise increase the neuromuscular function of knee flexors in untrained men. J Strength Cond Res 37(11): 2158-2166, 2023-Nordic (NHE) has been proposed reduce flexor (KF) injuries. However, submaximal alternatives NHE are necessary for clinical or weaker population. The aim this study was compare effects training (NHT) eccentric...
