Improving Heterogeneous Catalyst Stability for Liquid-phase Biomass Conversion and Reforming

Jeremy Luterbacher, Florent Emmanuel Héroguel, Bartosz Rozmyslowicz

Biomass is a possible renewable alternative to fossil carbon sources. Today, many bio-resources can be converted to direct substitutes or suitable alternatives to fossil-based fuels and chemicals. However, catalyst deactivation under the harsh, often liqui ...

Optimizing Fueling Decisions for Locomotives in Railroad Networks

Michel Bierlaire, Prem Kumar

Even though rail transportation is one of the most fuel efficient forms of surface transportation, the cost of fuel constitutes one of the major categories of very high operating costs for railroad companies. In the United States, unlike in Europe, fueling ...

Configurable Modular Multilevel Converter (CMMC) for Flexible EV

Alfred Rufer, Rosa Martel Danoary Tsirinomeny

Today, there is a long-term trend towards bi-directional and flexible charger functions for not only drawing current from the grid but also feeding excess energy back into it. The Configurable Modular Multilevel Converter (CMMC) offers a large flexibility ...

Tunable Capacitors and Microwave Filters Based on Vanadium Dioxide Metal-Insulator Transition

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Antonio Paone

We report the fabrication, modeling and characterization of novel microwave tunable capacitors based on the metal-insulator transition (MIT) of Vanadium Dioxide (VO2). We present the advantages of VO2-based capacitors over alternative technologies for micr ...

Motion of an elastic capsule in a constricted microchannel

Lailai Zhu, Cecilia Rorai

We study the motion of an elastic capsule through a microchannel characterized by a localized constriction. We consider a capsule with a stress-free spherical shape and impose its steady-state configuration in an infinitely long straight channel as the ini ...

A lignocellulosic ethanol strategy via nonenzymatic sugar production: Process synthesis and analysis

Jeremy Luterbacher

The work develops a strategy for the production of ethanol from lignocellulosic biomass. In this strategy, the cellulose and hemicellulose fractions are simultaneously converted to sugars using a γ-valerolactone (GVL) solvent containing a dilute acid catal ...
