Carbon nanotubes have long been touted as the wonder material of the future but their wonder properties can also be their downfall. The non reactive nature of carbon nanotubes means they can be difficult to incorporate into other materials for real world applications.
To this end, researchers have now extensively studied the wettability of carbon nanotubes in the form of powder, grown on a Si substrate and as CNT sheets or mats, or bucky paper.
The international research team of Uwe Vohrer, Justin Holmes, Zhonglai Li, AunShih Teh, Pagona Papakonstantinou, Manuel Ruether and Werner Blau, published their work in a special edition of the open access journal, AZoJono. This special edition of AZoJono* features a number of papers from DESYGN-IT, the project seeking to secure Europe as the international scientific leader in the design, synthesis, growth, characterisation and application of nanotubes, nanowires and nanotube arrays for industrial technology.
The researchers found that plasma polymerisation of a carbofluorine monomer onto a bucky paper leads to superhydrophobic surfaces. They also found that under gentle oxidation parameters the vertical alignment of multi wall nanotubes remains unchanged whereas more harsh conditions destroy the carbon nanotube shape without opening the end caps.
However, the most important finding was that when the carbon nanotube bucky papers were processed using a plasma treatment utilising oxygen containing process gases or post treatment reaction with oxygen after plasma activation they were able to convert the surface from hydrophobic to hydrophilic. Suitable treatments resulted in instant wetting and contact angles of less than 10° which could pave the way for carbon nanotube incorporation into many new applications as well as improved properties for those materials and application that already involve carbon nanotubes.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
