A study on synergies of combined pulp and fuel production

François Maréchal, Julia Granacher, Tuong-Van Nguyen

To limit climate change by reducing global greenhouse gas emissions, a transition away from fossil fuels is required. Biofuels represent a promising low carbon alternative for sectors that are hard to electrify, such as aviation. The integration of bio ref ...

Practical challenges in the development of photoelectrochemical solar fuels production

Sophia Haussener, Miguel Antonio Modestino

This article addresses the challenges presented by photoelectrochemical solar fuels technology in a discussion that begins with a functioning device and proceeds to the more fundamental science of its component parts. In this flow of discussion issues are ...

Long-term evolution of solid oxide fuel and electrolysis cell 3-D microstructure

Giorgio Rinaldi

Solid oxide fuel cells (SOFC) are highly efficient electrochemical conversion devices for the production of electricity that combine fuel flexibility with low emissions of pollutants. The reverse operation in electrolysis mode (SOEC) allows storing electri ...

Distributed Graph-based Convoy Control for Networked Intelligent Vehicles

Alcherio Martinoli, Ali Marjovi, Joseph Chadi Benoit Lemaitre, Milos Vasic

This paper presents an approach for formation control of multi-lane vehicular convoys in highways. We extend a Laplacian graph-based, distributed control law such that networked intelligent vehicles can join or leave the formation dynamically without jeopa ...

Growth of CH3NH3PbI3 cuboids with controlled size for high-efficiency perovskite solar cells

Michael Graetzel, Norman Pellet, Jeong-Hyeok Im

Perovskite solar cells with submicrometre-thick CH3NH3PbI3 or CH3NH3PbI3-xClx active layers show a power conversion efficiency as high as 15%. However, compared to the best-performing device, the average efficiency was as low as 12%, with a large standard ...

Development and application of an advanced fuel model for the safety analysis of the generation IV gas-cooled fast reactor

Until about the year 2030, current-day nuclear power plants (NPPs) will be replaced by so-called Gen-III or Gen-III+ units, which are mainly based on light water reactor technology. The principal new features are increased safety and improved economical ef ...
