Dr Barsan’s research focuses on the understanding and application of surface interactions of materials with gases. Since 1984, when he started his scientific carrier at the Institute of Materials Physics and Technology in Bucharest, he was interested in the basic understanding of phenomena taking place at the surface of metal oxides operated in realistic conditions for gas sensing applications. Besides that, he also explored different technologies for devising better gas sensing materials and innovative sensors based on them. In Bucharest he also gained experience in applying gas sensors to practical applications and the design and fabrication of monitoring instrumentation such as leak detectors and alcoholmeters. Currently, he is still holding a CS I (since December 2005) position at the institute, which was renamed National Institute of Materials Physics and he is a Supervisor for Doctoral Theses at the University of Bucharest (since November 2008).
Since 1995 he is a senior researcher at the Institute of Physical Chemistry of the University of Tübingen where, since 1999, is leading together with Prof. Udo Weimar the Gas Sensor research group. Since 2010 he is allowed to supervise PhD research.At the Institute of Physical Chemistry, he advanced his interest in the basic understanding of sensing with metal oxide pioneering the operando approach; the latter employs a host of spectroscopic and phenomenological characterization techniques, applied in sensor operation conditions, for a complete description of the gas sensing and transduction processes. Besides the obvious scientific value, the wealth of information gained by applying this approach has important practical applications. For example, it was proved that it is possible to monitor the influence of technology – thermal treatment, surface additives, synthesis processes - on sensors’ performance.
On the technology side, he invented the hybrid microsensor production technology based on the combination of sensing layers based on pre-processed powders and micromachined Si transducers. In 2001, with funding from private investors, he co-founded Advanced Sensing Devices (ASD) with the intention to bring his developments in the field of metal oxide gas sensors to the market. ASD merged with Applied Sensors in 2003 and established itself as a leading European company in the field of gassensor technology and application developments. During his working period at ASD and Applied Sensors, between May 2001 and December 2006, he was involved in the development and industrialization of micro gas sensors and in their application to the automotive field; to date, more than 30 million devices, of the type invented by Dr. Barsan, were commercialized by AppliedSensors.
In 2006 he co-founded AO Action, which is a Steinbeis Transfer Centre working in the exploitation of advanced sensing technologies. The Centre provides commercial services to private clients and works with consortia to exploit the results of publicly-funded research. Dr. Barsan is one of the two directors and currently runs 3 projects for industrial customers.
His research was funded by a host of German (BMBF and DFG) and European projects, e.g. Nanogas, CIA, Parfum, CMOSSens , GASMOH, ADA, GOSPEL, Clear-up, Netcarity, etc. He was the Project Coordinator of the European Project EASTGAS and part of the co-ordinating team for Gospel Network of Excellence; he is currently part of the co-ordinating team of Clear-up European Integrated Project. He is a reviewer for many prestigious scientific journals such as: Sensors and Actuators B, Thin Solid Films, Journal of Electroceramics and IEEE Sensors Journal and for the publications of IoP. He was also involved in the organisation of a series of International Conferences such as: the 7th International Meeting on Chemical sensors, Beijing, China (July 1998), the 6th International Symposium Olfaction and Electronic Nose, Tübingen, Germany (September 1999), the series of the International Seminars on Semiconductor Gas Sensors, SGS, taking place at Ustron, Poland, of the International School on Gas Sensors, S. Cesarea Terme (Lecce), Italy May 28 – June 2, 2001, the 203rd Meeting of Electrochemical Society, April 27-May 2, 2003 Paris, France. He is co-organizing the workshop on Gas Sensors based on Semiconducting Metal Oxides (starting 2007).
The actual research interests of Dr. Barsan are still directed towards basic science, technology and application developments. He is currently developing novel metal oxide materials by taking advantage of all existing knowledge and infrastructure for the operando studies and he tries to extend the expertise of the group in the direction of oxide electronics and catalysis. He is also exploring biomimetic approaches for gas sensing and novel synthesis and deposition technologies for improved selectivity and sensitivity.On the application side, he is targeting solutions for the fields of process control, health and environmental monitoring (both indoor and outdoor) and ambient assisted living.
