Carbon nanotubes are one of the most intriguing new materials with extraordinary properties being discovered in the last decade. The unique structure of carbon nanotubes provides nanotubes with extraordinary mechanical and electrical properties. The outstanding properties that these materials possess have opened new interesting researches areas in nanoscience and nanotechnology. Although nanotubes are very promising in a wide variety of fields, application of individual nanotubes for large scale production has been limited....
This volume contains three chapters written by distinguished scientists from
Europe, South America, and Asia. When it comes to the chemistry and physics
of carbon, as reflected by the authorship in this series since its inception 40
years ago, globalization (a popular term among today’s politicians and economists)
has always been the rule rather than the exception or a recent trend. If anything,
The New York Times editorial of May 7, 2004 is indeed correct in its
conclusion that “the United States . . .
Carbon nanotubes are rolled up graphene sheets with a quasi-one-dimensional structure of
nanometer-scale diameters. More than twenty years have passed since the pioneering work on
carbon nanotubes by Prof. Iijima in 1991. During all these years, carbon nanotubes have at‐
tracted a lot of attention from physicists, chemists, material scientists, and electronic device
engineers because of their excellent structural, electronic, optical, chemical, and mechanical
Carbon dioxide is produced in several anthropogenic activities at a rate of ca.
35 Gt/y. The main sources are: (1) the combustion of fossil carbon (production of
electric energy, transport, heating, industry), (2) the utilization of biomass (combustion
to obtain energy, fermentation), and (3) the decomposition of natural
carbonates (mainly in the steel and cement industry).
Activated carbon (AC) from coconut shells is used as support for platinum catalysts. A series of catalysts based on platinum and Pt doped Sn were prepared by impregnation on different supports like AC and SiO2. It was shown that the nature of the support has a significant influence on the activity and selectivity to alkenes of the catalysts in the dehydrogenation of nhexane to alkenes. The higher activity and selectivity of the carbon supported platinum catalyst can be explained by higher dispersion of platinum particles of the catalysts.
Calcium carbonate scale inhibition in squeeze treatment by the phosphonate–type scale inhibitors, such as diethylenetriamine penta (methylene phosphonic acid) (DETPMP), ethylene diamine tetra(methyelne phosphonic acid) (EDTMP) or by the mixing of DETPMP, EDTMP and chelants (citric acid (CA), maleic acid (MA), ethylendiamintetraacetic acid (EDTA) has been studied in previous works [5,6].

This book provides excellent review on the techniques for fabrication aimed to specific
applications for current technology. A tremendous amount of work is presented on
different modeling and simulation based on the applied semiconductor physics of
carbon nanotubes. In the past decades, although carbon nanotubes have undergone massive research,
considering the success of silicon, it has, nonetheless, been difficult to appreciate the
potential influence of carbon nanotubes in current technology....
This book has been outlined as follows: fabrication techniques followed by an analysis
on the physical properties of carbon nanotubes, including density of states and
electronic structures. Ultimately, the book pursues a significant amount of work in the
industry applications of carbon nanotubes. A list of the chapters is given below.
In contrast to our previous study (Barth & Marx, 2008) dealing with a currently decreasing
research field (high-temperature superconductors) we analyzed here a topic which has
raised a strongly increasing interest among researchers: research activities around carbon
nanotubes (CNTs or NTs). Carbon nanotubes (often named only nanotubes) are graphite
sheets rolled up into cylinders with diameters of the order of a few nanometers and up to
some millimeters in length with at least one end capped with a hemisphere of the fullerene
Sustainable forest management (SFM) is not a new concept. However, its popularity
has increased in the last few decades because of public concern about the dramatic
decrease in forest resources. SFM is generally implemented using criteria and
indicators (C&I) that define forest management standards, and several countries have
established their own sets of C&I within the framework of different international or
regional processes. Nevertheless, none of the C&I systems have been universally
accepted and future research should consider the current and future indicators....
The utility of primer pairs in SCoTs was advocated by Gorji et al. (2011). SCoT
markers are generally reproducible, and it is suggested that primer length and annealing
temperature are not the sole factors determining reproducibility (Gorji et al., 2011). They are
dominant markers, however, while a number of co-dominant markers are also generated
during amplification, and thus they could be used for genetic diversity analysis (Collard &
Mackill, 2009b). This has been validated through study of genetic diversity among rice
varieties (Collard & Mackill, 2009b).
I was delighted to respond to an invitation from Ventus Publishing to write a book on
atmospheric pollution. It is a topic well enough served by books in the past, but has become
increasingly important during these early years of the 21st Century. I believe therefore that there
is a place for a review like this one and that notwithstanding the immense activity in the area the
book will have a reasonable shelf life. This is because it continually relates the discussion to the
principles of physics and chemistry, and these do not change....
Wide agreement as to a clear and useful nomenclature is of great benefit in
any field of science. The nomenclature here presented merits wide acceptance
among terpene and other interested chemists because of the thorough way in which
the careful work was done. Many versed in the chemistry of terpenes and many
others experienced in naming chemical compounds were consulted. Full opportunity
for criticism was offered.

projections of future drilling, natural gas production, and related economic impacts (Considine,

Marcellus production has on prices for natural gas and expenditures for natural gas and
electricity in Pennsylvania. This report also presents an analysis of labor market and sales tax
data that affirms the economic stimulus provided by the Marcellus industry.
This book is a collection of some of the invited talks presented at the international
meeting held at the Max Planck Institut fiir Physik komplexer Systeme, Dresden,
Germany during August 6-30, 2001, on the rapidly developing field of nanoscale
science and bio-electronics (http://www.mpipks-dresden.mpg.de/~nanobio/).
Semiconductor physics has experienced unprecedented developments over the second
half of the twentieth century. The exponential growth in microelectronic processing
power and the size of dynamic memories has been achieved by significant downscahng
of the minimum feature size.
Numerous authors proposed chapters on their work, and those presented here are the
fruit of those proposals. As editor of this book, it has been my pleasure to collaborate
with these many, fine contributing scientists. This text brings forth a great amount of
fresh information on the biogeography and ecology of poorly known taxa and
landscapes, and explores biogeographic processes not previously studied. The
assembled work is an anthology of issues in modern biogeography, with topics
ranging across regional to global spatial scales, and ecological to evolutionary
An IELTS candidate who achieves a score of 7.0 is described as being a ‘good user’ of English,
someone who ‘[h]as operational command of the language, though with occasional inaccuracies,
inappropriacies and misunderstandings in some situations’ (International English Language Testing
System, 2009, p 3). As previously noted, since this research was conducted, DIAC has changed the

English language proficiency, candidates now need an Overall score of 8.0, with 8.
This ancient Native American proverb and what it implies resonates
today as it has become increasingly obvious that people’s actions
and interactions with the environment affect not only living conditions
now, but also those of many generations to follow. Humans must
address the effect they have on the Earth’s climate and how their choices
today will have an impact on future generations.
