Informing Neural Networks with Simplified Physics for Better Flow Prediction
Surrogate deep neural networks (DNNs) can significantly speed up the engineering design process by providing a quick prediction that emulates simulated data. Many previous works have considered improving the accuracy of such models by introducing additiona ...
2023How to Decarbonize Our Energy Systems: Process-Informed Design of New Materials for Carbon Capture
Berend Smit, Susana Garcia Lopez
Decarbonisation from a variety of industrial and power emission sectors highlights a marked need for capture technologies that can be optimized for different CO2 sources and integrated into an equally diverse range of applications of captured CO2 as a feed ...
WILEY-V C H VERLAG GMBH2023Process-informed adsorbent design guidelines for direct air capture
Berend Smit, Susana Garcia Lopez, Fergus Robert Lloyd Mcilwaine
Direct air capture using solid adsorbents is a proven technology critical to reducing our net greenhouse gas emissions to zero and beyond. Currently, academic research into the technology mainly focuses on the devel-opment of new adsorbents. However, there ...
ELSEVIER SCIENCE SA2022Increasing Superstructure Optimization Capacity Through Self-Learning Surrogate Models
François Maréchal, Ivan Daniel Kantor, Julia Granacher
Simulation-based optimization models are widely applied to find optimal operating conditions of processes. Often, computational challenges arise from model complexity, making the generation of reliable design solutions difficult. We propose an algorithm fo ...
2021Exergy and exergoeconomic analyses of sustainable furfural production via reactive distillation
Lignocellulosic biomass is a potential renewable resource for production of high-value, sustainable products. Furfural is among the important bio-based chemicals in biorefineries. However, the conventional process of furfural production using a reaction-se ...
2021Fabrication of zipping electrostatic actuators incorporating inkjet-printed layers
Herbert Shea, Samuel Rosset, Giulio Grasso
Zipping electrostatic actuators operate by bending flexible electrodes using electrostatic forces. This principle allows the use of a wide range of dielectric and conductive materials. Additive Manufacturing (AM) techniques can be used to fabricate these a ...
SPIE-INT SOC OPTICAL ENGINEERING2021The Industrialization of Astronomical Instrumentation: An Industrial Systems and Process Engineering Perspective
Jean-Paul Richard Kneib, Mohamed Bouri, Ricardo Jorge Araùjo Pereira, Luzius Gregor Kronig, Loïc Grossen
The Sloan Digital Sky Survey V (SDSS-V) is an all-sky spectroscopic survey of > 6 million objects, designed to decode the history of the Milky Way, reveal the inner workings of stars, investigate the origin of solar systems, and track the growth of superma ...
SPIE-INT SOC OPTICAL ENGINEERING2020Natural iron ligands promote a metal-based oxidation mechanism for the Fenton reaction in water environments
César Pulgarin, Stefanos Giannakis, Giulio Farinelli
The Fenton reaction is an effective advanced oxidation process occurring in nature and applied in engineering processes toward the degradation of harmful substances, including contaminants of emerging concern. The traditional Fenton application can be rema ...
ELSEVIER2020On the assessment of aspheric refractive microlenses
Refractive microlenses and microlens arrays are key components for many applications such as optical data communication, laser and medical devices, or cameras. In particular, refractive micro-optics enables the miniaturization of high-tech systems but also ...
EPFL2020Fabrication of clamped-clamped beam resonators with embedded fluidic nanochannel
Philippe Renaud, Luis Guillermo Villanueva Torrijo, Annalisa De Pastina, Damien Maillard, Stefano Silvio Giovanni Varricchio, Carlo Ricciardi, Davide Scaiola, Stefano Stassi
Suspended nanochannel resonators (SNRs) are promising devices able to characterize mass down to the attogram scale, thus being able to detect nanoparticles or biomolecules. In this paper, we present a flexible fabrication process for SNRs based on a sacrif ...
