Abstract:

The location and diffusion properties of template molecules in the zeolite channel have been investigated based on molecular dynamics method. Simulation results show that template molecules can reside in the supercages and the sinusoidal channels of the zeolite with good stability. It has been found that template molecules can diffuse easier in the supercages than in the sinusoidal channels, which means that template molecules can desorpt from the supercages more easily. Since the template molecules are nearly still in the sinusoidal channels, we can conclude that the template molecules can bind strongly with the sinusoidal channels, with a high desorption temperature. Additionally, the decomposition of the template molecules has happened before desorption from the zeolite.

Abstract:

The Influences of external donors on MgCl₂-Supported Ziegler-Natta catalyst, which is containing diethyl phthalate, diisobutyl phthalate and di-n-octyl phthalate internal donors have been investigated. New and improved processes require full control of kinetics, polymer properties and particle morphology. Typically, the catalyst is combined with an aluminum alkyl for the activation of the active center and an external donor for selectivity control, also known as the selectivity control agent. The activity of catalyst decreased when the ED was added, while the isotactivity increased. When increase the ED concentration, the activity of the atactic fraction decreased clearly, however isotactic polymer fraction in comparison with increased. Increasing of isotactic polymer fraction is mainly because of the raised number of stereospecific sites and the reduced number of nonstereospecific sites in the presence of external donor. With consider to PTES and PTMS influence on the isotactic index of polypropylene, there was not evident variation among the catalysts. The catalyst systems using PTMS and DIBP as an ED and ID, considering the relation to the activity of the catalyst, respectively, were the best. In these systems, the isotactic index raised with less reduction in activity. Regarding PTMS and DPDMS effects on the I.I, we achieved that the last, when used as an ED, is better than the former regardless of any ID. With simple instrumentations, spherical MgCl2 supports were prepared at a lower stirring speed of dispersion (600 - 2000 rpm). When the EtOH/MgCl2 ratio ranged from 3.0 to 3.5, the ethanol content in the resultant supports was appropriate for preparing Ziegler–Natta catalysts without removing the unneeded ethanol. ED, coordinating on titanium atoms adjoining magnesium atoms, could poison atactic active sites or converted them into isotactic ones. Overall, the percentage of the active sites in the system got the dominance. The result of investigation indicates that the activity of catalyst decreased while the isotactivity increased.

Abstract:

Despite substantial advances in sensing technologies, the development, preparation, and use of self-testing devices is still confined to specialist laboratories and users. Decentralized analytical devices will enormously impact daily lives, enabling people to analyze diverse clinical, environmental, and food samples, evaluate them and make predictions to improve quality of life, particularly in remote, resource-scarce areas. In recent years, paper-based analytical tools have attracted a great deal of attention; the well-known properties of paper, such as abundance, affordability, lightness, and biodegradability, combined with features of printed electrochemical sensors, have enabled the development of sustainable devices that drive (bio)sensors beyond the state of the art. Their blindness toward colored/turbid matrices (i.e., blood, soil), their portability, and the capacity of paper to autonomously filter/purge/react with target species make such devices powerful in establishing point-of-need tools for use by non-specialists. Depending on analytical requisites, different types of paper (filter, office) and configurations (1D, 2D, 3D) can be adopted. A wide overview regarding application ranging from DNA to heavy metals, through pesticides detection will be provided, with the aim in showing the potentialities of paper-based electrochemical biosensors for improving society involvement in monitoring.

Abstract:

Catalysis plays an integral part of industrial chemical processes and about 90% are catalytic processes. Heterogeneous catalysts enjoy some privileges over homogeneous counterparts because of advantages like low loadings, easy separation, recyclability etc. Intrinsically, catalysis is a surface phenomenon and several insoluble organic and inorganic nanomaterials with high surface area exhibit better catalytic performances.

Graphene is an infinite two-dimensional carbon monolayer made entirely of sp² carbon atoms arrayed in a honeycomb fashion. Graphene and other chemically modified graphene (CMGs) have been used in catalysis over the last decade. While CMGs are often used in organic catalytic processes utilizing the advantages of different functional groups and high surface area, reduced graphene oxides (considered as equivalent to graphene), having rich p-electron networks and high surface area are often decorated with metal nanoparticles (NPs) and the resulting nanocomposites could serve as potential heterogeneous nanocatalysts in diverse metal-catalyzed organic reactions.

With a brief background on the process of making different carbon nanomaterials, judicious functionalization and fabrications with metal/metal oxide NPs along with some of our research findings in graphene-based catalytic applications will be discussed in this presentations.

Abstract:

A one-step solvothermal method was recently applied to produce heterojunctions made of CuBi₂O₄ nanocolumns with small platelike CuO nanoparticles homogeneously distributed over its surface. Simulated solar light and visible light irradiation was used to investigate and study the photocatalytic activity of the heterojunctions through the photodegradation of Methylene Blue (MB) dye and Metronidazole (MTZ), respectively. The heterojunction CuBi2O4/CuO with 16.8 w/w% of CuO showed an enhanced photocatalytic performance with 98% removal of MB (@2 sun simulated solar irradiation) and 36% removal of MTZ (@1 sun visible light) within 60 min of irradiation. Using the optimized photocatalyst an apparent quantum efficiencyof ∼2.1% was achieved for MB photocatalytic degradation under excitation at 540 nm. This presentation will discuss the band energy alignement in this photocatalytic system and also correlate it with other published results in the literature. Finally, the enhanced photocatalytic performance of this system is attributed to an effective charge separation through a type-II heterojunction, indicating that photoinduced electrons transfer from CuBi₂O₄ to CuO nanoparticles with the photoholes migrating in the opposite direction. The main reactive species responsible for the photocatalytic degradation of organic pollutant molecules will be debated as well as the photocatalyst stability over repeating cycles.

Abstract:

The palladium plays a crucial role in organic synthesis and procedures including oxidation and isomerization reactions. Here, the review introduces catalytic transformation of biomass to renewable chemical materials by catalytic reactions as various olefins and natural oils. Several strategies have evolved for non-redox metal ions promoted Pd(II) catalysis activity of olefins isomerization, methyl linoleate isomerization and fatty acids oxidation reactions. In this review: firstly, we illustrate that the nonredox metal ions accelerate Pd(II)-catalyzed olefin isomerization  with Highly efficiency, while Pd(II) alone is very sluggish. Density functional theory (DFT) calculations further confirmed the sharp decrease of the energy barrier in C−H activation by the heterobimetallic Pd(II)/Al(III) species. In addition, this work described the transesterformations of methyl linoleate as biomass to its conjugated derivatives. It was found that using non-redox metal ions like Sc(III) to Pd(OAc)₂ catalyst can sharply improve the efficiency Pd(II) catalyzed methyl linoleate to its conjugated deviates in mixture solvent at 110℃. Finally, the modification Wacker-type oxidation for vegetable oils to corresponding Keto Fatty Acids/Esters (FAMEs) with Pd(II)/Lewis Acid in acetonitrile mixture with water as a solvent. Strong Lewis acids like Sc(OTf)₃ as non-redox metal ions was using with sample of Pd(OAc)₂ under aerobic conditions and, it generated the Sc(III)…H-Pd(II) complex that consequently hold the key active species for Wacker-type oxidation.
