We report on a colorimetric carbon monoxide (CO) sensor based on a rhodium complex. The sensor relies on changes in the light absorption properties of the chemochromic reagent when exposed to the gas. Its optical properties in solution and in a polymeric m ...

Swarms of robots can quickly search large environments through parallelisation, are robust due to redundancy, and can simplify complex tasks like navigation compared to a single robot. Flying swarms can rapidly cover rough terrain and have elevated sensing ...
Flip buckets are terminal spillway elements, generating free jets for energy dissipation. Deflectors are an alternative to flip buckets with constructional ease yet of similar hydraulic features. A first experimental study published at the 33rd IAHR Congre ...
Based on almost 18 months of continuous direct measurements coupled with an electronic questionnaire, we have analysed the influence of indoor temperature and illuminance, outdoor climate parameters, thermal and visual sensation, clothing and season on the ...
One of the most critical challenges facing society today is climate change and thus the need to realize massive energy savings. Since buildings account for about 40% of global final energy use, energy efficient building climate control can have an importan ...

Using extensive field survey data acquired over the past 8 years at the Solar Energy and Building Physics Laboratory at EPFL in Switzerland, comprehensive models of occupants’ presence, opening and closing of windows and the raising and lowering of blinds ...
Growing population, consuming a large amount of energy such as combustion of fossil fuel, increasing pollutant emissions in the atmosphere are the threats to the sustainable development of our planet in general, and of the air quality in particular. Accord ...
Cr contamination, generated by system components located upstream a solid oxide fuel cell (SOFC) and responsible for Cr-poisoning induced air electrode performance degradation, must be suppressed by hindering the access of Cr pollutants to the cathode comp ...
More than 8.5 million people live in the urban area of Bogotá and more than 1.4 million vehicles are taking the road every day. Air pollution is becoming more and more of a problem. Today, air pollution related respiratory diseases are the main cause of de ...
The building sector alone accounts for around half of the energy consumed in Switzerland and most other developed countries, with associated adverse environmental consequences, and there is a great potential for savings in this sector. For this reason, the ...
