Printing of Electrochemical Energy Storage Device Components
Materials printing is a versatile technology used in a wide range of industrial-scale manufacturing processes that require high-precision transfer of materials on different substrates. Despite the numerous studies available ... -
Cole-Cole Relation for Long-Chain Branching From General Rigid Bead-Rod Theory
(2020-08)Empirically, we find that parametric plots of the imaginary versus real parts of the complex viscosity may depend neither on temperature, nor on average molecular weight. Moreover, for fixed polydispersity, these Cole-Cole ... -
Gas diffusion electrode design for electrochemical carbon dioxide reduction
(Royal Society of Chemistry, 2020-10-05)Anthropogenic carbon dioxide (CO2) emissions contribute to the greenhouse effect and global warming, which can lead to undesirable climate change and extinction of species. Besides the ongoing efforts to develop environmentally ... -
Energy Recovery from High Salinity Biomass
Phytoremediation is a biological remediation technique where plants take contaminants from the soil into their biological structure. This technique removes pollutants from the ground leaving the grown biomass requiring ... -
Toll-like receptor mediated responses to adsorbed damage-associated molecular patterns on biomaterial surfaces
The foreign body reaction is a chronic inflammatory response to an implanted biomaterial that ultimately leads to fibrous encapsulation of the implant. It is widely accepted that the host response to implanted biomaterials ... -
Using Prior Parameter Knowledge in Model‐Based Design of Experiments for Pharmaceutical Production
(Wiley, 2020-08-11)Sequential model‐based design of experiments (MBDoE) uses information from previous experiments to select new experimental conditions. Computation of MBDoE objective functions can be impossible due to a non‐invertible ... -
Fundamentals of Electrochemical CO2 Reduction on Single-Metal-Atom Catalysts
(American Chemical Society, 2020-08-06)Electrochemical carbon dioxide (CO2) reduction powered by renewable electricity offers a path to produce valuable products from CO2 —this earth-scale human waste— and to store intermittent renewable energy in the form of ... -
Extended cross decomposition for mixed-integer linear programs with strong and weak linking constraints
(Elsevier BV, 2018-11-02)Large-scale mixed-integer linear programming (MILP) problems, such as those from two-stage stochastic programming, usually have a decomposable structure that can be exploited to design efficient optimization methods. ... -
A joint decomposition method for global optimization of multiscenario nonconvex mixed-integer nonlinear programs
(Springer Science and Business Media LLC, 2019-11-01)This paper proposes a joint decomposition method that combines Lagrangian decomposition and generalized Benders decomposition, to efficiently solve multiscenario nonconvex mixed-integer nonlinear programming (MINLP) problems ... -
A new cross decomposition method for stochastic mixed-integer linear programming
(Elsevier BV, 2017-01-16)Two-stage stochastic mixed-integer linear programming (MILP) problems can arise naturally from a variety of process design and operation problems. These problems, with a scenario based formulation, lead to large-scale MILPs ... -
A new optimization model and a customized solution method for natural gas production network design and operation
(Wiley, 2017-03-01)This article proposes to tackle integrated design and operation of natural gas production networks under uncertainty, using a new two-stage stochastic programming model, a novel reformulation strategy, and a customized ... -
A multi-commodity flow formulation for the optimal design of wastewater treatment networks
(Elsevier BV, 2020-03-04)The wastewater treatment network (WWTN) optimization problem can be viewed as an extension of the generalized pooling problem (GPP), where not only the different streams are mixed and split, but also some chemical components ... -
Optimal Utilization of Natural Gas Pipeline Storage Capacity Under Future Supply Uncertainty
(Elsevier, 2020-05-07)The ability of pipelines to store gas by increasing their operating pressure, or linepacking, is a common operational practice used to mitigate future operational uncertainty. The optimal operation of a gas pipeline network ... -
Synthesizing Systems Biology Knowledge from Omics Using Genome‐Scale Models
(Wiley, 2020-06-24)Omic technologies have enabled the complete readout of the molecular state of a cell at different biological scales. In principle, the combination of multiple omic data types can provide an integrated view of the entire ... -
