Joint Production and Energy Modeling for Sustainable Manufacturing Systems

This dissertation proposes a framework for addressing challenges of joint production and energy modeling for manufacturing systems. The knowledge generated is used to improve the technological readiness of manufacturing enterprises for the transition towards sustainable manufacturing in the context of smart electric grids. Detailed research tasks of the framework on the modeling of production, energy efficiency, electricity demand, cost, and demand response decision making have been implemented. Specifically, the dynamics and performance measures of general manufacturing systems with multiple machines and buffers have been modeled. Expressions of electricity energy efficiency and cost have been established based on the electricity pricing profile. Production scheduling problem formulations and the solution technique are discussed. New insights are acquired based on the applications of the established model in system parameter monotonicity analysis, rate plan switching decision making, and demand response scheduling. The findings based on case studies show that with appropriate adjustment of production routines, significant improvement in energy efficiency and substantial savings in energy cost can be achieved without sacrificing production. Appropriate implementation of this research outcome may lead to energy-efficient, electricity-demand-responsive, and cost-effective operations and thus improve the sustainability of modern manufacturing systems. The new knowledge generated can be implemented to discrete manufacturing in various industries such as automotive, electronics, appliances, aerospace, etc

Highly Permeable and Robust Responsive Nanoporous Membranes by Selective Swelling of Triblock Terpolymers with a Rubbery Block

The selective swelling of amphiphilic block copolymers has been demonstrated to be extremely facile and efficient in producing nanoporous membranes. However, all previous works are limited to diblock copolymers composed of two glassy blocks, suffering from inherent mechanical weakness. Here we elucidate the selective swelling-induced pore generation of triblock terpolymers with a rubbery polyisoprene (PIP) block, polyisoprene-<i>block</i>-polystyrene-<i>block</i>-poly­(2-vinylpyridine) (PIP-<i>b</i>-PS-<i>b</i>-P2VP). A short exposure to ethanol turns the initially dense films to nanoporous membranes with well-defined interconnected porosity. We fabricate composite membranes with the nanoporous terpolymer thin films as the selective layers deposited on macroporous substrates. Using PS-<i>b</i>-P2VP diblock copolymer without a rubbery third block for comparison, we identify the role of the rubbery PIP blocks in determining the mechanical properties as well as the swelling behaviors of the terpolymer. The rubbery PIP blocks enhance the mechanical robustness of the nanoporous membranes as revealed by nanoindentation tests on one hand and evidently accelerate the swelling process because of their softening effect to the PS matrix on the other hand, thus leading to 2–3-fold improved permeability. Moreover, the membranes exhibit a fast stimuli-responsive function as well as enhanced hydrophilicity because of the preferential aggregation of P2VP chains on the pore walls

Sn@CNT Nanostructures Rooted in Graphene with High and Fast Li-Storage Capacities

Development of materials with carefully crafted nanostructures has been an important strategy for the next-generation lithium-ion batteries to achieve higher capacity, longer cycle life, and better rate capability. Graphene-based and Sn-based anode materials are promising anodes with higher capacities than graphite; however, most of them exhibit fast capacity fading at prolonged cycling and poor rate capability. This paper reports a hierarchical Sn@CNT nanostructure rooted in graphene, which exhibits larger than theoretical reversible capacities of 1160–982 mAh/g in 100 cycles at 100 mA/g and excellent rate capability (828 mAh/g at 1000 mA/g and 594 mAh/g at 5000 mA/g). The excellent electrochemical performances compared to graphene/Sn-based anodes have been attributed to the efficient prevention of graphene agglomeration by Sn@CNT decoration and the increased electrochemical activities of Sn by CNT shell protection and GNS support

Monolithic Membranes with Designable Pore Geometries and Sizes via Retarded Evaporation of Block Copolymer Supramolecules

We develop a retarded evaporation approach for the alignment of cylinder-forming block copolymer supramolecular monoliths, 3-<i>n</i>-pentadecyl­phenol (PDP) hydrogen-bonded polystyrene-<i>b</i>-poly­(4-vinylpyridine) (PS-<i>b</i>-P4VP). A variety of highly ordered, aligned morphologies are produced by varying the dosages of PDP in the supramolecules. Treatment of the aligned supramolecular monoliths in hot ethanol leads to the dissolution of PDP and the selective swelling of P4VP, yielding enlargeable ordered mesopores along the original P4VP/PDP domains. Particularly, from supramolecular monoliths aligned in the morphology of perpendicular cylinders and gyroids, we obtain highly ordered monolithic membranes containing enlarged straight pores and bicontinuous pores, respectively. The straight and gyroidal pores were filled with phenol–formaldehyde resol and further carbonized to produce well-defined carbon nanostructures including nanofibers and reversed gyroids, demonstrating the pore accessibility and the promising templating functionality of the resulted monolithic membranes

Molybdenum Disulfide Quantum Dots as a Photoluminescence Sensing Platform for 2,4,6-Trinitrophenol Detection

Transition metal chalcogenides, especially molybdenum disulfide (MoS₂), have recently attracted wide attention from researchers as graphene-analogous materials. However, until now, little literature has reported the synthesis of photoluminescent MoS₂ materials and their applications in analytical chemistry. We herein presented a facile bottom-up hydrothermal route for the synthesis of photoluminescent MoS₂ quantum dots (QDs) by using sodium molybdate and cysteine as precursors. The prepared MoS₂ QDs were characterized by transmission electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, photoluminescence spectroscopy, and UV–vis spectroscopy. The MoS₂ QDs were then used as photoluminescent probes to construct a photoluminescence (PL) quenching sensor for detection of 2,4,6-trinitrophenol (TNP). The TNP sensor presented a wide linear range from 0.099 to 36.5 μM with a high detection limit of 95 nM. Furthermore, the sensor displayed a high sensitivity toward TNP over other structurally similar compounds like 2,4,6-trinitrotoluene, p-chlorophenol, phenol, and 2,6-di-<i>tert</i>-butyl-4-methylphenol. To understand the origin of the high sensitivity, we assessed the emission wavelength-dependent PL quenching behavior of MoS₂ QDs by the above five compounds using Stem–Volmer equation in detail. The results showed that the novel approach we put forward can satisfactorily explain the interaction mechanisms between MoS₂ QDs and the five compounds, and the high sensitivity for TNP very likely originated from a combination of the PL resonance energy transfer, electronic energy transfer, and electrostatic interactions between MoS₂ QDs and TNP. Finally, the sensor was successfully applied for detection of TNP in water samples and test papers
