    ABSTRACT: A new technique of in situ doping of alkali metal (Li+, Na+, K+, Rb+, and Cs+) in Nb2O5 was showcased by the modified anodization of Nb foils at high frequency, negative-to-positive pulsed voltage. At the optimized dopant concentration and synthesis condition, the doped-Nb2O5 shows 2-fold enhancement in photoelectrochemical water splitting efficiencies compared to the undoped Nb2O5 electrode, as a result of improved charge carrier density and enhanced surface charge transfer.

    ABSTRACT: One of the most versatile and rapid manufacturing processes for a variety of nanopowders is flame-spray-pyrolysis (FSP). The production costs of this scalable process are largely controlled by the raw materials, pushing for the utilization of low-cost metal precursors. These, however, typically yield inhomogeneous products containing large particles up to micrometer size along with fine nanoparticles. Here we investigate the release mechanism of nitrate and carboxylate precursors from spray droplets by single droplet combustion experiments and thermogravimetric analysis. The results show that neither precursor evaporation nor choice of solvents are prerequisites for homogeneous nanopowders but droplet microexplosions with continuing combustion. It is shown that even low-cost metal nitrates yield homogeneous nanopowders if precursors are formulated such that droplet microexplosions occur by internal superheating. The proposed precursor release mechanisms are verified with lab- and pilot-scale FSP, demonstrating that single droplet combustion experiments can be employed to predict the product quality.

    ABSTRACT: Demand response (DR) is an integral part of the Smart Grid paradigm, and has become the focus of growing research, development, and deployment in residential, commercial and industrial systems over the last few years. In process systems, energy demand management through production scheduling is an increasingly important tool that has the potential to provide significant economic and operational benefits by promoting the responsiveness of the process operation and its interactions with the utility providers. However, the dynamic behavior of the underlying process, especially during process transitions, is seldom taken into account as part of the DR problem formulation. Furthermore, the incorporation of energy constraints related to electricity pricing and energy resource availability presents an additional challenge. The goal of this study is to present a novel optimization formulation for energy demand management in process systems that accounts explicitly for transition behaviors and costs, subject to time-sensitive electricity prices and uncertainties in renewable energy resources. The proposed formulation brings together production scheduling and closed-loop control, and is realized through a real-time or receding-horizon optimization framework depending on the underlying operational scenarios. The dynamic formulation is cast as a mixed-integer nonlinear programming problem based on a proposed discretization approach, and its merits are demonstrated using a simulated continuous stirred tank reactor where the energy required is assumed to be roughly proportional to the material flow.

    ABSTRACT: Describing multi-component adsorption is fundamental to using sorption in any chemical separation. 50 years ago, Myers and Prausnitz made a seminal contribution to characterization and prediction of multi-component adsorption by introducing Ideal Adsorbed Solution Theory (IAST). Here, we give an overview of IAST, highlighting its continued role as a benchmark method in describing adsorption using illustrative examples from a variety of experimental and molecular modeling studies. © 2015 American Institute of Chemical Engineers AIChE J, 61: 2757–2762, 2015

    ABSTRACT: Locked nucleic acids (LNAs) can greatly enhance duplex DNA stability, and are therefore creating opportunities to improve therapeutics, as well as PCR-based disease and pathogen diagnostics. Realizing the full potential of LNAs will require better understanding of their contributions to duplex stability, and the ability to predict their hydridization thermodynamics. Melting thermodynamics data for a large set of diverse duplexes containing LNAs in one or both strands are presented. Those data reveal that LNAs, when present on both strands, can stabilize a duplex not only through direct interaction with their base-pair partner, but also through nonlocal hyperstablization effects created by LNA:LNA base pairs and/or specific patterns of oppositely oriented LNA:DNA base pairs. The data are, therefore, used to extend a thermodynamic model previously developed in our lab to permit accurate prediction of melting temperatures for duplexes bearing LNA substitutions within both strands using a classic group-contribution approach. © 2015 American Institute of Chemical Engineers AIChE J, 61: 2711–2731, 2015

    ABSTRACT: The VLLE flash is important in water and hydrocarbons mixtures, hydrocarbon and CO2 rich mixtures, and hydrocarbon methane rich mixtures that are encountered in reservoir performance and recovery studies. A robust VLLE flash algorithm is proposed. The equilibrium and mass balance equations are solved as a constrained minimization problem. An inverse barrier function is used to handle the inequality constrains to solve for the phase fractions. It warrants always arriving to the solution. The challenging cases analyzed showed that the initialization procedure proposed, together with successive substitution iteration in the outer loop, is a good method for a stable VLLE flash algorithm, even near critical points. Whenever the result is in the region outside the three-phase physical domain, the solution suggests that the system has fewer phases. In one of the cases analyzed, a region with three liquid phases was encountered and the algorithm found two different solutions with positive phase fractions. © 2015 American Institute of Chemical Engineers AIChE J, 61: 3081–3093, 2015

    ABSTRACT: The permeability of light gases in a series of different glassy polymers is analyzed through a thermodynamic-based approach for solubility and diffusivity. The nonequilibrium thermodynamic model for glassy polymers describes the solubility of the different penetrants; diffusivity is given as the product of a mobility factor and a thermodynamic factor. The latter is predicted by the nonequilibrium lattice fluid thermodynamic model, while the mobility coefficient is determined using the experimental permeability data. For rather soluble penetrants (e.g., CO2), a plasticization factor is also accounted for, considering the mobility to depend exponentially on penetrant concentration, as often observed experimentally. The model is able to describe accurately the experimental behavior in a simple and effective way, considering only two adjustable parameters. The mobility coefficient is found to depend on the penetrant size (critical volume) and on the fractional free volume of the polymer matrix, following rather general and reasonable correlations. © 2015 American Institute of Chemical Engineers AIChE J, 61: 2776–2788, 2015

    ABSTRACT: Modelling of crude oil fouling in heat exchangers has been traditionally limited to a description of the deposit as a thermal resistance. However, consideration of the local change in thickness and the evolution of the properties of the deposit due to ageing or changes in foulant composition is important to capture the thermal and hydraulic impact of fouling. A dynamic, distributed, first-principles model of the deposit is presented that considers it as a multi-component varying-thickness solid undergoing multiple reactions. For the first time, full cleaning, partial cleaning and fouling resumption after cleaning can be simulated in any order with a single deposit model. The new model, implemented within a single tube framework, is demonstrated in a case study where various cleaning actions are applied following a period of organic deposition. It is shown that complete mechanical cleaning and chemical cleaning of different extent, according to a condition-based efficacy, can be seamlessly simulated. This article is protected by copyright.

    ABSTRACT: The effect of certain porous particles on vapor-liquid equilibrium(VLE) of ethanol + water, ethanol + ethyl acetate, acetic acid + ethyl acetate and n-hexane + n-heptane systems was investigated by using the headspace gas chromatography (HSGC) at 60°C, 50°C, 50°C and 50°C, respectively. Four kinds of porous particles were studied: molecular sieves (3 Å, 4 Å, 5 Å, and 13 X), activated carbons (columnar activated carbon, powdered activated carbon), activated alumina balls and non-polar adsorption resins (D4006, D4020). Good agreement was noticed when the experimental results in the absence of porous particles were compared with the NRTL model's predictions. These results added to the validity of using the HSGC in studying the VLE of binary systems. The results obtained showed that the VLE of these four kinds of binary mixtures in the presence of molecular sieves and activated alumina balls was altered considerably. The presence of activated carbons had no effect on the VLE of these binary systems, but the VLE of n-hexane + n-heptane system was altered in the presence of D4006 or D4020 non-polar adsorption resin. Other factors, such as pore size, type, weight, properties of porous particles and solvents were also investigated. The results showed that the alteration in the VLE of a given binary solution was a function of the pore size, type, weight, properties of porous particles and the properties of solvents. In addition, the mechanism of the porous particles altering the VLE was also analyzed accordingly. This article is protected by copyright. All rights reserved.
