Pd/ZnO nanocomposites were successfully synthesized by means of one and two pot synthesis and applied in the photodegradation of Rh6G. The nanocomposites were characterized by XRD, SEM, TEM, FTIR and micro-Raman spectroscopies. It was found the presence of PdZn2, PdO and agglomerated particles in the support surface for the Palladium-based nanocomposites fabricated by one-pot route; the two-step method allowed the formation of spherical Pd nanoparticles, with homogeneous distribution in the nanocomposite matrix, with an average size of 2.16 nm. The results show higher photocatalytic efficiency for the samples fabricated under the two-step approach compared to the one-pot synthesis. Based on experimental results, density functional theory (DFT) calculations were carried out to understand the enhancement photocatalytic of Pd/ZnO nanocomposites. To achieve it, the ZnO (001) and (101 …

The effect of pH on the structural, textural, morphological, and electronic properties of ZnGa2O4 nanoparticles obtained by coprecipitation using mild reaction conditions (25 °C; 30 min) was studied. The pH ranges in which coprecipitation reactions occurred and the chemical species associated with the reaction mechanism were identified. It was determined that the samples synthesized at pH values between 6 and 10 consisted of Zn-Ga oxide blends, with spinel ZnGa2O4 being the majority phase. Conversely, the material prepared at pH 12 was constituted by Zn-Ga layered double hydroxide phase along with wurtzite ZnO traces. The synthesis pH determined the reaction product yield, which decreased from 51 to 21% when the reaction medium turned from softly acidic (pH 6) to strongly alkaline conditions (pH 12). The bandgap energies of the synthesized materials were estimated to be in the range of 4.71–4.90 eV. A coprecipitation-dissolution-crystallization mechanism was proposed from the precipitation curve, with specific mononuclear and polynuclear species being involved in the formation of the different precipitates. Phenol was employed as a probe molecule to evaluate the photocatalytic performance of the synthesized samples. Among the samples, the one prepared at pH 6 showed the largest photodegradation efficiency (~98%), which was superior to commercial TiO2-Degussa P25 (~88%) under the same process conditions, which can be attributed to both its high specific surface area (140 m2 g−1) and the formation of a Zn2xGa2−2xO3+x/ZnGa2O4 heterojunction.

In this work, we synthesized and characterized carbon nitride (CN) nanoparticles obtained by the thermal treatment (550 °C) of urea, melamine, dicyandiamine, and dicyandiamine-barbituric acid in an open reactor and evaluated the effect of different precursors on the photocatalytic performance. CNs obtained from melamine, dicyandiamine, and dicyandiamine-barbituric acid were 3D melon-type structures. On the other hand, CN obtained from urea was a 2D microporous, amorphous structure whose melon or graphitic arrangement could not be determined. The presence of structural defective states (mainly C radicals) was corroborated by EPR studies of the solids. The photocatalytic activity of CN powders for methyl orange (MO) discoloration was investigated using 350 nm and simulated solar light (SSL) irradiation. MO removal efficiencies were correlated with the particle’s energy gap, specific surface area …

Deep-fat frying is a unit operation where foods are cooked by immersion in hot oil at temperatures above the boiling point of water, typically ranging from 150 to 220 C (Devi et al., 2020; Gouyo et al., 2021b). The food is not only partially dewatered, but it also absorbs oil while developing unique flavour, colour, and texture characteristics (Kumar et al., 2017). When fried, foods develop an outer dry crust, while the core remains moist and soft (Devi et al., 2020; Gouyo et al., 2021a). Most of the oil gained by food remains confined to the surface region immediately after frying (Khalilian et al., 2021; Al Faruq et al., 2022). This oil gradually infiltrates the crust during the post-frying cooling period (Bouchon and Pyle, 2005a; Touffet et al., 2020). As fried foods increase their oil content up to 40% in mass, this is a major concern for health-conscious consumers (He et al., 2012; Wanakamol and Poonlarp, 2018; Topete-Betancourt …

The effect of different modeling assumptions on the estimated water diffusivities and kinetic parameters for oil transfer during deep-fat frying of foods is investigated. Modeling assumptions include the use of several common calculation bases to express water loss and oil absorption, leading to implicit simplifications such as constant density, constant concentration of fat-free solids or constant concentration of non-defatted solids. The proposed model was used to analyze frying experiments conducted with potato strips (9.5 mm× 9.5 mm× 80 mm) at different temperatures (160, 175 and 190 C), where product shrinkage was followed via image analysis. The proposed model was solved under two-dimensional mass transfer and water diffusivities were estimated by the method of slopes, with and without considering the dimensional changes of product. Mean water diffusivities were calculated in the range of 0.89× 10-8 to …

First-principle calculations have been performed to explore the initial stages of the zinc blende-like germanium carbide epitaxial growth on the gallium nitride (001)-(2 × 2) surface. First, we studied the Ge/C monolayer adsorption and incorporation at high symmetry sites. Results show that the adsorptions at the top and hcp1 sites are the most stable structures of C and Ge, respectively. Different terminated surfaces were used on the GeC epitaxial growth. According to the surface formation energies, only the first two bilayers are stable; therefore, the GeC epitaxial growth is favorable only under N-rich conditions on a Ge-terminated surface and with Ge bilayers terminated. In addition, it is demonstrated that GeC bilayers on the C-terminated surfaces are unstable and preclude the epitaxial growth. Electronic properties have been investigated by calculating the density of states (DOS) and the projected density of states (PDOS) of the most favorable structures.

The evolutionary selection is proposed as the actual growth mechanism of supported layered double hydroxide (LDH) frameworks constituted by interconnected sheet-like structures with apparent preferential orientation. This growth mechanism was emulated through an algorithm that accounts for different synthesis conditions. The generated structures were compared with supported ZnAl-LDH frameworks synthesized by hydrothermal route using different precursor concentrations and reaction temperatures. The simulated structures were found to mimic the topology of the synthesized LDH frameworks. Moreover, the proposed model anticipates the effect of the synthesis parameters in the resulting morphological features. Finally, the distinctive characteristics of those structures generated by the evolutionary selection mechanism are proposed.

Quantum-mechanics calculations were carried out within the density functional theory (DFT) scheme, to analyze the sorbate-sorbent interaction between DNA nucleobases (purines: guanine and adenine; pyrimidines: cytosine and thymine) and hexagonal boron nitride nanosheets (pristine and non-stoichiometric) in two phases: i) gas and ii) aqueous. The resulting molecular simulations for the pristine nanosheet indicate that the four molecular sorbates prefer to be oriented perpendicular and/or parallel respect to sorbent. This geometrical effect generates adsorption energies associated to non-covalent interactions (physisorption), being the preferential adsorption sites those of N atoms of the nanosheet. According to the calculated quantum descriptors, they exhibit low chemical reactivity and work function, as well as high polarity and semiconductor-like behavior. However, the homonuclear boron bonds in the …

Abstract Ag2O was synthesized by the precipitation method and it was used as support to prepare Ag/Ag2O nanocomposites using different sodium citrate volumes to control the size and amount of Ag nanoparticles. Materials were characterized by X-ray powder diffraction, diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy, scanning and transmission electron microscopy and nitrogen adsorption–desorption at − 196 °C analyses, respectively. Ibuprofen was selected as a probe molecule and materials were assessed as photocatalysts under simulated visible light irradiation. The SEM and TEM analysis revealed the presence of Ag nanoparticles over Ag2O support showing a size increase as citrate volume increased. By means of DRS analysis a band gap shift was observed, suggesting the formation of metallic silver during Ag impregnation while XPS results proved the co …

BiOI nanostructures were synthetized through a hydrothermal process using either bismuth acetate or subsalicylate as Bi precursor. Regardless of the used Bi source, the same crystalline structure of BiOI was obtained; nevertheless, the nature of the Bi precursor had an evident impact in the color appearance of the obtained sample. Another notable difference was observed in the resulting morphology, where∼ 1.6 μm flower-and dandelion-like shapes were obtained for acetate and subsalicylate, respectively; both structures assembled by around 30 nm thick nanoflakes with rounded and straight edge, respectively. UV–vis diffuse reflectance shows an energy gap around 1.8 eV. Raman spectroscopy confirms also the tetragonal phase of BiOI. The photocatalytic activity was evaluated through degradation of methyl orange dye using visible and UV light sources, comparing results with P25 TiO 2. Both BiOI …

Se generalizó el método de reguladores lineales cuadráticos (LQR, por sus siglas en inglés) para permitir la sıntesis de controladores PID en procesos con múltiples entradas y múltiples salidas. El método propuesto se aplica secuencialmente para producir las acciones proporcional, integral y derivativa. Se conciben tres usos principales para la metodologıa propuesta:(i) el diseno≪ de novo≫ de controladores PID,(ii) la adición de la acción derivativa a controladores PI existentes y (iii) la diagonalización de las matrices de ganancias PID. Adicionalmente, los dos últimos procedimientos se pueden aplicar a controladores disenados con diferentes metodologıas. El método desarrollado se aplicó al diseno≪ de novo≫ de un controlador centralizado PID para columna de destilación de tres entradas-tres salidas ası como a la adición de la acción derivativa a controladores existentes PI centralizados y multilazo para un reactor continuo de tanque agitado (CSTR, por sus siglas en inglés) no lineal. El método LQR propuesto permitió la sıntesis de controladores PID centralizados y multilazo con mejores caracterısticas de seguimiento de referencia, rechazo a perturbaciones, uso limitado de la senal de control e insensibilidad a incertudumbre en el modelo de la planta que aquellos reportados por otros autores.
