The political, technological, and economic change over the last 20 years does not only result in a reallocation of political power balances. Former leading industrial nations will primarily be displaced by new aspiring countries. Now, China passed Japan in 2010 to become the world's second-largest economy after the U.S., and is expected to spend $153.7 billion on R&D in 2011 (1.4% of GDP). That isn't half of respective U.S. expenses ($405 billion = 2.7% of GDP), but nonetheless the trend is clear. China's R&D investments are growing at a rate that comes close to the annual economic growth.


Europe with $270 billion (2010) is still ahead of China but has to bundle up in the forthcoming 5 to 10 years. While the European countries are generally in the saving money mode and are mainly facing red colours in their balance sheets, China has positive balanced bank accounts. In Europe, Germany ranks first with estimated expenditures on R&D totalling $69.5 billion (2.3% of GDP) in 2011, followed by France with $42.2 billion (1.9% of GDP) and U.K. with $38.4 billion (1.7% of GDP)*.


Therefore, in our nanotimes we will stronger focus on Asian research results - mainly from China and India - besides the coverage of American and European technological advancements. According to the UNESCO Science Report 2010, Asia has the largest percentage of scientists (World Share Researchers) with almost 41%, followed by
Europe with 30% and USA with 20%. 


Hence it is not surprising that this edition contains a variety of Chinese research results such as tumour cells killed by gold nanorods [page 64], progresses in photo-detectors based on metal selenide nanomaterials [page 64], synthetic route for production of micro to nano scale metallic glassy fibres [page 67], nanostructures via a surfactant-assisted self-assembly (SAS) by using an oil/water system as medium [page 66].


The focus in 2011 will remain on the Company-News section and the News in Brief but also on important fundamental research and technological breakthroughs. In this edition, for example, you can find articles on high-efficiency PV-cells, new solar cells, an autonomous microchip not needing batteries, holographic structures, high quality CNT-based TFTs on a plastic substrate.


The nanotimes will remain free of charge for its readers. The readership has constantly increased over the last years, especially in Asia and the U.S. A Big Thanks goes to our company sponsors.


Of course, we are still looking for companies or foundations as sponsors and for advert placement. It represents a great opportunity for European companies that want to present their brand to Asian and American readers. In addition, Chinese, Indian or Russian companies that are not yet well known in Europe or in the USA wanting to enter these markets should consider a sponsorship or an advert placement option.

World's First Successful Operation of CNT-based Integrated Circuits Manufactured on Plastic Substrates [70]


CNT-based ICs
CNT-based ICs


As part of NEDO's Industrial Technology Research Grant Japan-Finland collaborative project, Professors Yutaka Ohno from Nagoya University in Japan and Esko I. Kauppinen from Aalto University in Finland along with their colleagues have developed a simple and fast process to manufacture high quality carbon nanotube-based thin film transistors (TFT) on a plastic substrate. They used this technology to manufacture the world's first sequential logic circuits using carbon nanotubes. 


Porphyrin Supramolecular Nanostructures [66]

Researchers from Institute of Chemistry, Chinese Academy of Sciences (ICCAS) have found that a Zinc porphyrin (ZnTPyP) could be controlled assembled to form diverse nanostructures via a surfactant-assisted self-assembly (SAS) by using an oil/water system as medium


Surrey NanoSystems [08]

Surrey NanoSystems, U.K
., announced the first  sales of its innovative new nanomaterial growth system, the NanoGrowth-Catalyst, to the École Polytechnique of Montreal, and the University of Surrey's Advanced Technology Institute. 


These leading research organisations have chosen the NanoGrowth-Catalyst as a platform for their work on materials including carbon nanotubes, silicon nanowires, graphene and nanoparticles for semiconductor, optical device and other applications. The growth system's multi-chamber design ensures the purest nanomaterial processing conditions by continuously maintaining the substrate under vacuum, from the deposition of catalysts to growth of materials.  

Vistec Semiconductor [40]

Vistec Electron Beam GmbH announced that the company is ready to provide its electron-beam lithography systems with a vacuum compatible air-bearing based positioning system overcoming the limitations of roller bearings for future performance requirements. The new platform is designed to support both Vistec's Variable Shaped Beam (VSB) writers as well as the Multi Shaped Beam (MSB) lithography system currently under development.

The combination of the new highly sophisticated platform with advanced variable shaped beam electron optics enables Vistec to address mask writing as well as electron-beam direct write application demands for future technology nodes according to the ITRS roadmap. In addition, a multitude of special application needs, e.g. in the micro- and nano-optics area will be met.


Furthermore, Vistec Lithography Inc. has received an order from Turkey for one of its electron-beam lithography systems. The global supplier of advanced electron-beam lithography systems will deliver anEBPG5000plusES to the newly formed Nanotechnology and Application Center (SUNAC) of the Sabanci University based in Istanbul.


NanoFocus [33]

The German manufacturer of high-precision optical 3D surface analysis tools NanoFocus AG (Frankfurt: N2F) starts the product development of a new sensor generation with a major contract from the medical technology industry. The optical sensors in the high end segment will become part of a new product family implementing most recent, state-of-the-art technology.


Microchip Harvests its Own Energy [45]

Researchers from the University of Twente's MESA+ Institute for Nanotechnology, together with colleagues from the University of Nankai in China and University of Utrecht, Netherlands, have for the first time succeeded in manufacturing a microchip with an efficient solar cell placed on top of the microelectronics. 


The researchers presented their findings at the International Electron Device Meeting in San Francisco. 

Production of Nanoscale Metallic Glassy Fibres (MGFs) [67]

Recently, WANG Wei Hua's group in Institute of Physics, Chinese Academy of Sciences, developed a synthetic route for production of micro to nano scale MGFs (the diameter ranges from 100nm to 70nm) by driving bulk metallic glass rods in their supercooled liquid region via superplastic deformation. 


Patents [78]

Nanowire Structure  


A method for the production of nanowires has been developed. The wires are arranged between two layers to avoid tangling of the wires. The arrangement of the nanowires between two layers is particularly suitable for use in a microreactor or catalyst. Hereby, the fluid is guided through the chamber between the two layers. With the new production method, specific surfaces of up to 5mm2 / (cm2 µm) can be realized.


Gunn Diode on GaN Substrate for the Generation of High Frequency Signals  With High Power 


The invention refers to GaN Gunn diodes which were produced on a GaN substrate and are suitable for generating millimetre waves with very high power. Due to one particular embodiment and arrangement of the contacts, it was possible to generate stable current voltage curves with a well marked negative differential resistance using these novel components. Thereby, significantly higher field strengths than the threshold field strength can be used.  


2D and 3D Imaging With Terahertz Radiation 


The new sensor serves for a three dimensional detection of an object by using electromagnetic high-frequency radiation in the THz frequency range. The sensors arrangement is based on a radiation source, a receiver and a signal source.


Cyclopentadienylphosphazene Complexes (CpPN Complexes) of Metals of the 3. and 4. Group and of the Lanthanoids

The invention at hand provides cyclopentadienylphosphazene complexes (CpPN complexes) of the metals of the third and the fourth group and of the lanthanoids with the exception of lutetium for the first time. These complexes may be produced in situ, in which it is not required to make use of the partially unstable alkyl compounds of these metals. Instead, the readily available and stable metal halides are utilised.
