12.11.2014 – Open day at the Redox Flow Battery demonstrator in Martigny

The “portes ouvertes” at the redox flow battery (RFB) demonstrator in Martigny was a great success! Many cooperators, politicians and interested people from the region and whole Switzerland took the chance to discuss with LEPA scientists and Prof. Hubert H. Girault and to see the 10 kW vanadium RFB demonstrator under operation. Such mega batteries are dedicated to store energy generated e.g. by wind and sunlight. But what happens once the battery is fully charged but energy is still produced? LEPA and collaborators have developed a strategy to generate hydrogen under such conditons in a dual circuit. This hydrogen can be used as a fuel for cars or to produce methane gas from CO2 generated at the adjacent water treatment plant. Methane can be used as well as fuel for combustion engines. In this way, LEPA and the EPFL contributes in several research areas of renewable energy conversion and storage in Switzerland.

2014 – New X-Serie inkjet printer at LEPA!

The Laboratory of Physical and Analytical Electrochemistry (LEPA) has acquired a new X-Series inkjet printer from Ceradrop, Limoges, France. Ceradrop is a subsidiary of the MGI Group and focuses on Printed Electronics and Smart 3D Printing. The X-Serie printer represents an advanced and powerful digital materials deposition system featured by high accuracy and controllability, multiple printheads and several embedded post-process technologies. This new machine will be applied to support several of LEPA’s research areas including energy storage and conversion (batteries and fuel cells), as well as analytical chemistry (environmental sensing, proteomics and medical diagnostics).

05.05.2014 – Installation of the new Redox Flow Battery Demonstrator in Martigny

The LEPA staff and invited guests visited the installation of the new Swiss Redox Flow Battery (RFB) demonstrator in Martigny, Switzerland. A commercial dual-circuit RFB (10 kW) has been installed which is funded by the Swiss Federal Office of Energy (SFOE), Sinergy and the Centre de recherches energetiques et municipals (CREM). LEPA’s objective is to extend the commercial RFB by a coupled system to generate hydrogen while storing electrochemically energy. The aim is to complement electrochemical energy storage and to circumvent the low energy densities of the RFBs. More details about the project can be found here.


29.04.2014 – Professor Hubert H. Girault selected for the 2015 Charles N. Reilley Award from the American Society of Electroanalytical Chemistry
“The Charles N. Reilley Award in Electroanalytical Chemistry is given in memory of one of the most distinguished analytical chemists of the 20th century. Reilley’s interests were both fundamental and broad; he made seminal contributions not only to electroanalysis, but also optical spectroscopy, NMR, chromatography, data analysis, instrumentation, and surface analysis. The signature of his research was to decline empiricism, seeking a basic understanding of measurements and detection schemes. Reilley recognized that measuring things is at the heart of modern chemistry.”
The award ceremony will take place at the Pittcon conference in March 2015 in New Orleans.
Prof. Girault’s research focuses on electrochemistry, biosensors, electrophoresis and ionization methods for mass spectrometry. He is one of the pioneers of charge transfer reactions at soft interfaces and in particular of photo‐induced electron transfer reactions mimicking photosynthesis towards water splitting. His research group has been active in biosensor research integrating microtechnologies to produce electrochemical immunosensors, recently dedicated to allergy research. His work in electrophoresis led to the development of “Off Gel Electrophoresis” now commercialized worldwide by Agilent Technologies and used by most proteomic laboratories. Over the last few years in collaboration with Fudan University (Shanghai) his group has developed novel ionization methods for mass spectrometry such as Electrostatic Spray Ionization (ESTASI) used for ambient mass spectrometry imaging of surfaces. He is currently Associate Editor of Chemical Science, Royal Society of Chemistry.
12.02.2014 – LEPA Fondue

Under the guidance of Dr. Fernando Cortes Salazar, LEPA organized a traditional Swiss Fondue, which is based on melted cheese, white wine and some garlic prepared in a pot and eaten by immersing long small forks with a piece of bread into the cheese, stirring, removing and putting pepper on it. Bon appétit!
