    ABSTRACT: In this study, a superhydrophobic, fire-resistant, and mechanical robust sponge was fabricated through a two-step polyphenol chemistry strategy for efficiently absorbing oils/organic solvents (rapidness in absorption rate and large quantity in absorption capacity). Specifically, the Fe(III)-polyphenol complex is formed upon the metal-organic coordination between tannic acid (TA, a typical polyphenol) and Fe(III) ions, which is spontaneously coated on the surface of the pristine melamine sponge. Then, free catechol groups in the polyphenol are applied for grafting 1-dodecanethiol, thus generating the superhydrophobic sponge. Several characterizations have confirmed the chemical/topological structures, superhydrophobicity, fire-resistant merits, and mechanical robust property of the sponge. As a result, this sponge exhibits excellent absorption capacities of oils/organic solvents up to 69-176 times its own weight, indicating promising sorbents for removing oily pollutants from water. Meanwhile, owing to the facile fabrication process and inexpensive/easy available raw materials, the large-scale production of this sponge will be convenient and cost-effective.

    ABSTRACT: Previously developed kinetic and dynamic models of the hydroformylation of 1-dodecene in a thermomorphic multicomponent solvent system (TMS), consisting of DMF, n-decane, and hydroformylation products, were experimentally validated applying various operation modes, such as batch, semibatch, and perturbed batch operation. On the basis of experimentally obtained data, which cover a broad range of physical conditions, the parameters of the reaction kinetics were refined to give reliable model predictions as basis for rigorous process optimization. The improved model was used for dynamic optimization to obtain optimal trajectories (e.g., temperature and gas dosing fluxes versus reaction time), which maximize the selectivity to the desired linear aldehyde product. The predicted optimal trajectories were successfully validated in semibatch reactor experiments.

    ABSTRACT: Due to the special cavity structure, cyclodextrins become the perfect candidates for biomimic catalyst acting like enzymes. In this paper, hydroxypropyl-β-cyclodextrin (HP-β-CD) is used as a phase transfer catalyst for the preparation of glycidyl monostearate (GM) from SN2 substitution reaction by means of the formation of an inclusion complex. FT-IR, 1HNMR, and GC-MS characterization verified the formation of GM. The calculated inclusion constants of HP-β-CD/epichlorohydrin and HP-β-CD/GM inclusion complex were 6.377 and 6709.4 L/mol, respectively. Then, a series of characterizations further demonstrated the formation of a stable inclusion complex. Therefore, the catalytic mechanism of GM synthesis using HP-β-CD as catalyst was confirmed. The experimental results show the yield of GM can reach 92.6% under the optimum reaction conditions. The kinetics demonstrates the interactions between HP-β-CD and substrate. The feasibility of HP-β-CD as a biomimic catalyst will provide a new direction for the synthesis of monoglyceride.

    ABSTRACT: A recently designed packing sheet Winpak was assembled with catalysts in a modular catalytic structured packing (MCSP) column. A combined mesoscale-microscale methodology was used to analyze and determine the pressure drop mechanism in the MCSP. The proposed methodology differentiates the pressure drop into six different principles, which was determined and compared using computational fluid dynamics (CFD). The three major causes are gas flow confluence and diffluence through the packing windows, the sudden change in the effective gas channel area and the wall effect. Inspired by constructal theory, the height of packing sheets loaded with catalysts was reduced, which resulted in a less abrupt gas channel contraction and expansion at the packing layer junction and more favorable for the undisturbed gas flow. The optimized overall pressure drop was reconstructed in Fluent and was validated by both dry and irrigated packing experiments. Furthermore, irrigated packing experiments were also conducted. Result comparisons reveal that the proposed optimization method is reliable and accurate. This methodology is shown to be significant in the optimization of Winpak-based MCSP.

    ABSTRACT: The impedance spectroscopy was used for studies of the electrical conductivity and the electric charge relaxation in diluted solution of propylene carbonate + lithium perchlorate (the mole fraction xLiClO4 = 6•10-5), in the temperature range from 250 K to 350 K. It was found that the viscosity behavior of the conductivity as well as the charge relaxation time related to the Li+ and ClO4ˉ ions immersed in propylene carbonate quite good fulfil the Stokes-Einstein hydrodynamic model. An essentially limited ions-pairing process in studied solution of a low ions concentration and considerably limited dipolar aggregation of propylene carbonate molecules are considered as essential factors determining the dynamic behavior of the ions immersed in that strongly polar liquid.

    ABSTRACT: Agent-based models (ABM) provide a flexible multi-layer platform to incorporate various modeling techniques into a single hybrid model for designing optimal biomaterial scaffolds for angiogenesis in tissue engineering applications. Scaffold geometrical variables are considered as design variables. The growth factor concentration profile is the only process variable considered in the study. The product variables used to illustrate the combined effects of scaffold design variables and process variables on the outcome of angiogenesis include the density and depth of capillary invasion within the scaffold. The scaffold design process and the ABM developed to simulate angiogenesis are described in this paper. The performance of the ABM and vascularization of polymer scaffolds are evaluated by simulation studies. The effects of pore size, pore size distribution, and interconnectivity on total blood vessel length, invasion depth, and the total number of sprouts formed during the vascularization process are reported. The integration of the simulation of angiogenesis with ABMs and scaffold design techniques provide an iterative process for designing optimal scaffold structures. This facilitates faster design of optimized scaffolds with significantly less cost and enables better understanding of the mechanisms of angiogenesis of polymer scaffolds for tissue engineering applications.

    ABSTRACT: Herein, we have reported particle-assisted ion-imprinted cryogels, which were synthesized by embedding finely crushed functional particles into cryogel structure under semifrozen conditions. These cryogels showed high adsorption efficiency and affinity against CdII ions. CdII adsorption performances were evaluated by varying some effective factors. In order to analyze the data, we applied Langmuir and Freundlich adsorption isotherms while using three different kinetic models, pseudo-first-order, pseudo-second-order, and Weber-Morris as well. Also, the dimensionless equilibrium parameter (RL), initial adsorption rate, and half-adsorption time were calculated. The results revealed that ion-imprinted-polymer (IIP) cryogels have homogeneously distributed cavities, which were formed by a particle-assisted imprinting process, and the theoretical maximum adsorption capacity (Qmax, 35.97 μg/g) was very close to the experimental value (Qeq, 32.15 μg/g). In addition, RL values for both IIP and nonimprinted-polymer cryogels showed favorability of the adsorption process, while kinetic models indicated that there were no diffusion limitations during the adsorption process, which means that the rate-limiting step was chemosorption of heavy-metal ions on binding sites (imprinted cavities or functional groups) with a high initial adsorption rate and a low half-adsorption time. Desorption, reusability, and selectivity studies were also conducted to state the performance of the cryogels. In conclusion, this promising approach provides a novel methodology for selective CdII removal from water sources.

    ABSTRACT: High-end electric products require high frequency and high speed printed circuit broads (HFS-PCBs), while high performance resin is the key for fabricating HFS-PCBs. A new resin system (DPDP/CE) was developed by copolymerizing 10-(2,5-dihydroxyphenyl)-9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DPDP) and 2,2′-bis(4-cyanatophenyl) propane (CE). Compared with CE resin postcured at 250 °C for 4 h, the DPDP/CE system that was only postcured at 220 °C for 2 h has outstanding flame retardancy, greatly reduced water absorption, low dielectric loss, and high thermal resistance. For DPDP1.4/CE resin with 1.4 wt % phosphorus content, its dielectric constant and loss at 1 GHz are 2.71 and 0.005, respectively, and hardly change after staying in boiling water for 100 h. Different from UL-94 V-2 rating of CE resin, the flame retardancy of DPDP1.4/CE resin is desirable UL-94 V-0 rating, resulting from both gas-phase and condensed-phase mechanisms. These attractive features suggest that the DPDP/CE system is suitable to fabricate HFS-PCBs for high-performance electric products.

    ABSTRACT: New experimental data are reported for equilibrium adsorption isotherm and mass transfer of pure argon on a sample of pelletized LiLSX zeolite. Model analysis of the data indicate that the zeolite behaved like a nearly homogeneous adsorbent for Ar adsorption while it exhibited substantial heterogeneity for adsorption of N2 and milder heterogeneity for adsorption of O2. The over-all mass transfer coefficient for Ar adsorption was comparable in magnitude with those of N2 and O2. The coefficient increased with increasing pressure and decreased with increasing temperature like those for N2 and O2. A large skin resistance at the adsorbent particle surface was observed for Ar mass transfer like that for adsorption of O2 and N2.

    ABSTRACT: The cyclohexanone ammoximation reaction in a monolithic reactor over titanium silicalite-1 (TS-1) was simulated based on our previous experiments. The catalyst powders of TS-1 were wash-coated on the internal surface of each channel in a honeycomb cordierite support, and external circulation was utilized to vary the flow rate of liquids passing through the channels. A one-dimensional model was employed to investigate the influences of temperature from 318.15 K to 343.15 K and external circulation flow rate of 265-765 mL min-1 on the conversion of reactants. The simulation was from startup to steady-state operation after enough iterative circulations, where the outcomes of simulation agreed favorably with experimental data, and the concentration changes in different computing circulation times are helpful to reveal the reaction process, determine the initial concentrations of reactants in the reactor for shortening duration of startup, and illustrate that the microchannels in the monolithic catalyst effectively provide a good mass-transfer process for the reaction.

    ABSTRACT: The linear PLLA/PDLA blends were prepared by solution mixing method, and the melting behavior and structure evolution of neat PLLA and PLLA/PDLA specimens were investigated in this study. Results indicated that PLA stereocomplex crystallites (sc) preferentially formed in all blends, and the crystal structure of PLA sc and homochiral crystallites (hc) did not vary as molecular weights. The melting temperature of PLA neat specimens (Thm) increased monotonously with molecular weights. However, significantly different from the neat samples, the melting temperature of PLA sc (Tsc) increased at first, then decreased as molecular weight of polymers increased from 4 to 100 kg/mol. When the molecular weights of PLLA and PDLA ranged from 23 to 50 kg/mol, multi-melting behaviors observed at 230 °C in the blends. After annealing at a fix temperature (Tsc-10 °C), the highest Tsc was observed at 249.9 °C in L32/D31 specimen, which was the highest report value until now. The WAXD and SAXS results attested that not crystal structure, but the variation of the thickness of lamellar crystal was the exterior reason, and the higher optical purity of PLLA and PDLA would be the inherent cause which resulted in the superior thermal properties. This investigation provides more potential for the application of PLA sc materials at higher temperature environments.

    ABSTRACT: Most bauxite-produced alumina is obtained by the Bayer process, but the production efficiency is limited by the slow gibbsite crystal growth due to the high concentration of NaOH in sodium aluminate solution. Here electrodialysis (ED) and electro-electrodialysis (EED) are coupled to separate NaOH from the sodium aluminate solution so as to enhance the gibbsite crystal growth rate and achieve high alumina production efficiency. The ED or EED process is also investigated before the coupling process to find the optimal operating conditions. The ED process indicates that the optimized current density is in the range of 45-60 mA cm-2 and the optimal membranes are CMV/AMV. The current density of 60 mA cm-2 can achieve a high recovery ratio (ηOH- 92.6%), low energy consumption (2.38 kW h kg-1), but a relatively high Al(OH)4- leakage ratio (ηAl(OH)4- 15.1%). The EED process indicates that with the optimized current density of 30 mA cm-2 and membrane CMV, the ηAl(OH)4- can be “zero” and the energy consumption can be as low as 2.07 kW h kg-1, but the treatment capability is low since OH- ions cannot be recovered directly and a single cation exchange membrane is used. The coupling process can combine the advantages of ED and EED, so that the ηOH- can keep a high value of 90.9%, the ηAl(OH)4- decreases to a low value of ∼5%, and the energy consumption remains low at 2.25 kW h kg-1. Overall, the coupling process of ED and EED is an excellent method to separate NaOH from the sodium aluminate solution.
