Microfluidic study in a meter-long reactive path reveals how the medium’s structural heterogeneity shapes MICP-induced biocementation
Lyesse Laloui, Dimitrios Terzis, Ariadni Elmaloglou
Microbially induced calcium carbonate (CaCO3) precipitation (MICP) is one of the major sustainable alternatives to the artificial cementation of granular media. MICP consists of injecting the soil with bacterial- and calcium-rich solutions sequentially to ...
2022Scale effects on efficiency and profitability in the Swiss banking sector
This paper analyzes efficiency and profitability in the Swiss banking sector over the period 1997–2019. We find strong evidence for scale economies: for most banks in the sample, efficiency and profitability increase with bank size. Using an instrumental v ...
2022Synthesis and direct assay of large macrocycle diversities by combinatorial late-stage modification at picomole scale
Christian Heinis, Gerardo Turcatti, Julien Bortoli Chapalay, Alessandro Angelini, Manuel Leonardo Merz, Sevan Mleh Habeshian, Jonathan Patrice Vesin, Mischa Schüttel, Ganesh Kumar Mothukuri, Gontran Sangouard, Cristina Diaz Perlas, Zsolt Bognár
Macrocycles have excellent potential as therapeutics due to their ability to bind challenging targets. However, generating macrocycles against new targets is hindered by a lack of large macrocycle libraries for high-throughput screening. To overcome this, ...

CNG power system (1) comprising a storage tank (6) connected fluidically to a fuel conversion system (2) via an energy transfer system (4), the fuel conversion system (2) comprising a power unit using CNG as fuel and generating gas emissions comprising C02 ...
2022Photo‐Electrochemical Conversion of CO 2 Under Concentrated Sunlight Enables Combination of High Reaction Rate and Efficiency
Sophia Haussener, Silvan Suter, Etienne Boutin, Mahendra Patel
Photo-electrochemical production of solar fuels from carbon dioxide, water, and sunlight is an appealing approach. Nevertheless, it remains challenging to scale despite encouraging demonstrations at low power input. Higher current densities require notable ...
Wiley2022Climate Action, Sufficiency, Deliberative Democracy
In an ideal world, sufficiency, efficiency, and clean energy would be balanced, with an emphasis on sufficiency in the critical decade ahead of us. Given this importance, how could we get closer to this ideal world, and improve the general acceptance of su ...
Business School Lausanne (BSL)2022The impacts of the gas diffusion layer contact angle on the water management of the proton exchange membrane fuel cells: Three-dimensional simulation and optimization
Jan Van Herle, Hossein Pourrahmani
Water management of the proton exchange membrane fuel cell (PEMFC) is an important parameter to improve efficiency, especially in cold weather conditions. The generated water of the electrochemical reactions inside PEMFC may stay inside the cell and fill t ...
