Nanotechnology in Turkey
Nanotechnology is going to have a big impact on the future.So, it is necessary for all countries special developing countries, to involve the technology. It seems nanotechnology could be an opportunity for countries to promote their industries and economics. Therefore it is necessary to have a nanotechnology profile for each country. Such profiles helps scientist to know facilities, experts and research centers in their countries.Turkey is a Eurasian country that stretches across the Anatolian peninsula in Western Asia and Thrace (Rumelia) in the Balkan region of southeastern Europe. Over the centuries, it has provided a geographical and cultural bridge between Asia and Europe. This study represents information about Turkey's institutes, research areas, scientists, collaborations, trends and some science and technology indicators in nanotechnology.
Emerging of Nanotechnology
The first nanotechnology conference was organized by Bilkent University in Ankara in the year 2005. The interest to this conference was great and the amount of participants was more than expected with high quality of scientific studies. Both state and private universities started to dedicate budgets for nanotechnology research, as well as, government and private foundations to support nanotechnology research after the conference. Additionally, Turkey has participated in the 6th Frame Programme of European Union and proposals related to nanotechnology and nanoscience have already being supported by the Programme. Under this frame, a National Nanotechnology Research Center was established by the contribution of Bilkent University and Turkish State Planning organization.
Policy and Strategy:
Turkey’s future strategies for nanoscience and nanotechnology have been estimated and determined by the Scientific and Technological Research Council of Turkey (TUBITAK) which states the aims and objectives by the year 2023. According to the Nanoscienceand Nanotechnology Strategies report of the TUBITAK the prior subjects concerning the nanotechnology are the following :
- Nanophotonics-Nanoelectronics-Nanomagnetism with the aim of being aninternational production center for integrated circuit systems with nanostructures.
- Nanomaterials: aimed to produce advanced nanocomposite materials, bio-inspired materials and catalysts, production of nanoelectronics and nanomechanical devices by self-assembling method.
- Fuel cells and energy: plan to produce fuel cells with high efficiency
- Nanocharacterization: aimed to improve scanning probe microscopes and atomic force microscopes.
- Nanofabrication: aimed to produce nanostructures and integrated circuit systems with competency.
- Nanosized quantum information processing: aimed to be competent on designing, simulating and producing of nanoscale units
- Nanobiotecnology: plan to improve DNA diagnosis.
Nanoscienceand Nanotechnology Indicators
Scienceindicators can determine the influential individuals, institutions, papers, publications, and countries in their field of study as well as emerging research areas, like nanotechnology, that could impact their work.This unique and comprehensive compilation of science performance statistics and science trends data is based on journal article publications and citation data from ISI web of knowledge. It is an ideal analytical resource for policymakers, administrators, analysts and information specialists in government agencies, universities, corporations, private laboratories, publishing companies and foundations, as well as members of the scientific press and recruiters.
Nanopatents, nano-articles and their citations as well as h-Index are main nanoscience and nanotechnology indicators in current study. H-index is based on a list of publications ranked in descending order by the times cited counts. The h-index is the number of items which is in the h rank of the mentioned ranking and has at least "h" citations. This metric is useful because it discounts the disproportionate weight of highly cited papers or papers that have not yet been cited .
Figure 1 shows number of nano-articles published by Turkish scientists during 2000 to 2012. As can be seen, there is significant growth after 2006 when special budget dedicated to nanotechnology in Turkey. Publishing more than 1050 nano-articles in 2012, Turkey ranked 22nd in the world. Turkey is the second largest nanoscience producer in Middle East after Iran. Saudi Arabia, Egypt and Iraq are 3th, 4th and 5th in the ranking respectively. Figure 2 gives share of nano-articles from all scientific publications in Turkey. The share was nearly doubled in 2011 compared with 2006 indicating Turkey attention to production of nanosciences during last years.

Fig.2.Share of Turkey’s nano-articles from all its ISI indexed publications
Fig.3. World rank of Turkey in h-Index & average citations per article
Figure 3 represents world rank of Turkey in two indicators during 2003 to 2012: h-Index and average citations per article. There are steep growths in the rank of both indicators. It means Turkey had considered the quality as well as the quantity of the nano-articles during the time span. It is third country, after Iran and Saudi Arabia, in h-Index in Middle East, but Turkey has lower average citation counts comparing with the EU countries.
Table 1 shows the number of Turkey’s nanopatents during 2001 to 2012. Table 2 represents list of the Turkish assignees published the patents. As can be seen, in 2011 and 2012 the number of nanopatents published by Turkish assignees increased.Sabanci University published highest number of nanopatents among all Turkish universities and research centers. In 2012, Turkey position in published nanopatents was 34th in the world (3th in the Middle East, after Saudi Arabia and Iran)

The National Metrology Institute of Turkey
The National Metrology Institute of Turkey (UME) is not an active institute in nanotechnology at Turkey but due to crucial role of UME in developing of nanotechnology in Turkey, it is introduced in this section.
UME works on whose foundation began in 1982, was formally established as an institute tied to the Scientific and Technological Research Council of Turkey (TÜBİTAK) in 1986 for the purposes of facilitating the development of the high-technology production capacity of the country’s industrial sector through building and improving the national measurement and metrology infrastructure. TÜBİTAK UME was established to be a primary level measurement center to meet the needs of private and public sector entities in industry and other relevant areas. TÜBİTAK UME, which has strived to meet the demands of all types of industry through the supply of calibration, testing, repair/maintenance services, as well as training and consulting in the field of metrology, has also aimed at making a contribution to the development of new technologies through the adoption of the newest techniques in measurement and calibration.
In 2007,TÜBİTAK UME ranked among the founding members of the European Association of National Metrology Institutes (EURAMET). In 2008, TÜBİTAK UME joined the ERA NET+ projects under the EU 7th Framework Programme in partnership with other European national metrology institutes. A project proposal made under the Instrument for Pre-Accession Assistance (IPA), for initiating the production of chemical reference materials in Turkey has been accepted. Training of the personnel to be employed in the project began, and work started in 2009. TÜBİTAK UME signed a contract with the Bureau of Metrology of Macedonia (BoM) for the provision of technical support within the scope of a World Bank assistance project.
