Abstract
This study has been carried out to analyze the research field of nanoparticles in
terms of publication output as per science citation index (1992- 2010). During 1992-2010
a total of 459 papers were published by the scientists in the field of nanoparticles The
average Number of Publications produced per year was 25.5%. The highest number of
publications 93 was produced in 2008. The most productive author is Khanna PK with 18
papers dealing with nanoparticles and 3.05% of all papers published in this research
field.. There were 24 countries involved in the research in this field India is the top
producing country with 457 publications (86.88%), Japan with 11 publications (2.09%),
USA with 9 Publications (1.71%), Germany with 8 Publications (1.52%). Indian Institute
of Technology topped the list with 56 publications followed by National Chemistry
Laboratory with 21 publications, Bhabha Atomic Research Center with 13 publications.
The most productive Journal is materials letters with 23 papers dealing with nanoparticles
and 11.97% of all papers published in this nanoparticles research field. The high
frequency keywords were: synthesis 123 (7.98%), Nano 78(5.06%), characterization
71(4.61%), properties 61(3.96%), and nanoparticles 49 (3.18%). It was observed that
82.78 percent of the Article was published in Proceedings Paper followed by 15.68
percent in Review, 1.52 percent
Keywords: Scientometrics Analysis, Nano, Nanoparticles, Nano technology, Nanoscience,
Sicentometrics study.
Introduction
Nowadays the scientometrics, studying mainly the quantitative aspects of science
(in cognitive, as well as in social context), has strengthen its position as a significant
component of the general Science of science, and it appears to be a completed
disciplinary field with clearly outlined subjects of research, specific set of good
elaborated research methods and techniques, a significant concerning size and
geographical scope research community, numerous research institutions. Research
publications are clearly one of the quantitative measures for the basic research activity in
a country. It must be added, however, that what excites the common man, as well as the
scientific community, are the peaks of scientific and technological achievement, not just
the statistics on publications. Many scientometrics studies have appeared in the literature
to focus on the performance of science in the field of nanoparticles.
Objective
The main objective of the study is to present the growth of world literature in
nanoparticles deposition and make the quantitative assessment of the research in terms of
year-wise research output, geographical distribution of research output, nature of
collaboration, characteristics of highly productive institution and the channel of
communication used by the scientists.
Methodology
Data was collected from the Science Citation Index (SCI) which is available via
the Web of Science (WoS). The WoS is the search platform provided by Thomson
Reuters (the former Thomson Scientific emerged from the Institute for Scientific
Information (ISI) in Philadelphia). SCI database is one of the very comprehensive
databases covering all aspects of science. The study period (1992- 2010) is selected as the
database is available in machine from since 1982. The search string “nanoparticles” in the
“Basic search” field of SCI was used for the year s 1992-2010 to download the records
on the subjects ‘nanoparticles’. A total of 459 records were downloaded and analyzed by
using the Histcite software application as per the objectives of the study.

During 1992- May 2010 a total of 459 publication were published in nanoparticles
by India. The average Number of Publications produced per year was 25.5%. The highest
number of publications 93 was produced in 2008.Table 1(a) was given year wise growth
and collaboration rate in nanoparticles. It can be clearly visualized from the table 1(b)
that growth of the literature was very low during 2007-May2010 and it peaked during
1997-2001. It Indicate that research in nanoparticles received a major impetus this period.
An Exponential growth in number of publication was observed during 1992-May2010.
The highest growth rate (9.5%) was found during 1997-2001 with 19 publication
followed by (7.5%) with 143 publication, during 2002-2006, (1.73%) with 243
publications and during 2007-May2010.Table 1(b) gives growth rate of publications in
nanoparticles research in different five years.

Keywords are one of the best scientometric indicators to understand and grasp
instantaneously the thought content of the papers and to find out the growth of the subject
field. Analysis of the keywords appeared either on the title or assigned by the indexer or
the author himself will help in knowing in which direction the knowledge grows. The
high frequency keywords will enable us to understand the various aspects of
nanoparticles under study. . The high frequency keywords were: synthesis 123 (7.98%),
nano 78(5.06%), characterization 71(4.61%), properties 61(3.96%), and nanoparticles 49
(3.18%).

Summary
In this study the literature on nanoparticles, a promising new material, has been
analyzed by scientometric methods. The time evolution of the overall number of citations
reveals that the impact increase of the nanoparticles papers is possibly going to outrun the
impact increase of the related research fields on Nanoparticles.
The highest growth rate (9.5%) was found during 1997-2001 with 19 publication
followed by (7.5%) with 143 publication, during 2002-2006, (1.73%) with 243
publications and during 2007-May2010.Table 1(b) gives growth rate of publications in
nanoparticles research in different five years.

nanoparticles and 3.05% of all papers published in this research field. The top 20 most
productive research in country wise, . India is the top producing country with 457
publications (86.88%), Japan with 11 publications (2.09%), USA with 9 Publications
(1.71%), Germany with 8 Publications (1.52%).
A research landscape has been established illustrating the major research clusters
with regard to the clustering concept. The most productive Journal is materials letters
with 23 papers dealing with nanoparticles and 11.97% of all papers published in this
nanoparticles research field.
The high frequency keywords will enable us to understand the various aspects of
