Elektrolitic nanostructures laboratory
Responsible contact person: Dr. László PÉTER (peter.laszlo (at) wigner.mta.hu)
The Electrodeposited Nanostructures Laboratory (ENL) is operated in the framework of Advanced Materials Laboratory of the Wigner Research Centre for Physics. The ENL is open for joint research with other laboratories as well as for measurement and research service based on work contracts. The description below summarizes the principles of all such activities called external research. Although a thorough overview was meant to offer, it is highly suggested that initiatives should be based on a satisfactory discussion of all conditions.
1. Joint research with partners within the institute and/or with other research institutions
Co-operative joint research should be based on mutual benefits. No cost will be charged for the usage of the instruments. Hence, it is expected that the partners(s) take part in either the maintenance of the instruments or the implementation of the facilities (if necessary). Consumables have to be provided. The dissemination of the results has to be done in joint publications where all members of ENL taking part in the joint work are eligible to be a co-author.
2. External contracts and work-for-hire
The ENL is open to perform research and experimental works falling in its profile in the framework of a service contract. In the case of measurement service, the daily charge of the instrument operation is between 0.9 and 1.5 % of the procurement price of the particular instrument (the longer the undivided research period, the smaller the daily cost). Besides the instrument operation, the above specified charge covers the overhead and the inexpensive consumables. The total cost may vary, depending of what kind of data evaluation and literature search have to accompany the primary measurements (but this cost is limited to 30% of the instrument operation fee). In case of all paid contracts, the results make a property of the contractor, the members of ENL are not necessarily a co-author of the publications (if any); nevertheless, the ENL has to be named as the service provider in any public appearance of the results.
The list below presents the short description of the instruments that are available in the ENL:
Electrochamical instruments
