A new type of electrode that could lead to the development of more efficient and lighter supercapacitors has been unveiled by researchers in India. The electrode has a new hybrid structure that is made from iron and nickel nanowires, and could be used to boost the capacitance, current density and charging/discharging rates of big capacitors used to store large amounts of electrical energy. The electrodes are inexpensive and environmentally friendly to produce, say the researchers, and could someday be used to make supercapacitors to power a range of devices, from mobile phones to electric cars.....
It is possible to modulate the nanoscale morphology of “supramolecular” self-assemblies of small organic molecules by simply changing the nature of the light that triggers the self-assembly process itself, say researchers in France and Germany. Although this type of process is known to occur in metallic nanoparticles, this is the first time that it has been seen in organic materials....
“Non-filling” carbon-coated porous silicon microparticles might be used to make an ultrahigh performance lithium-ion battery anode material, according to new experiments by researchers at Stanford University and the SLAC National Accelerator Laboratory in California. An electrode fabricated from the microparticles has a high reversible specific capacity of around 1500 mAh/g over 1000 cycles thanks to the fact that the particles prevent silicon from expanding during lithiation/delithiation.....
When carbon nanotubes are made, a mixture of single-, double- and multi-walled nanotubes are produced. The nanomaterials are also produced as a mix of both metallic and semiconducting tubes. This is a real problem when trying to make electronic devices from these structures because, ideally, either semiconducting or metallic tubes are needed depending on the application and not both. What is more, the tubes should either be predominantly single-, double- or multi-walled. Now, researchers in Germany and Australia have developed a new gel permeation method that can not only separate out double-walled tubes from the nanotube mix, but which can also distinguish the nanotubes by their electronic type. The purified tubes might now be used in real-world devices such field-effect transistors, sensors and transparent electrodes......

In a recent Asian-Pacific Newsletter on Occupational Health and Safety (Vol 19, number 3, December 2012), Prof. Sirirurg Songsivilai, NANOTEC Executive Director emphasized that the number of products currently on the market containing nanomaterials as the critical component or uses nanotechnology in crucial manufacturing process will increase from 1% to 10% in the coming decade. This is a significant increase and one which needs public attention as this may have impact on everyday life. In his recent speech to the participants of the workshop on “The Implementation of Nanosafety and Ethics Strategic Plan: Action Plan to AEC”, Prof. Sirirurg informed that the Thai government approved in 2012 the National Nanosafety and Ethics Policy Framework as the critical check and balance to the National Nanotechnology Policy Initiative to ensure sustainable development of nanotechnology. “The workshop will help to strengthen the understanding of the safety aspects of nanotechnology for representatives from associated organizations; government, public, and private sector, and will allow for establishment of the action plan for the Nanosafety and Ethics Strategic Plan 2012-2016” said Prof. Sirirurg. “In order to implement the action plan of Nanosafety and Ethics Strategic Plan, effectively and comprehensively, we must focus not only on the planning process, but the monitoring and evaluation process”. The workshop which was held on April 2 at Thailand Science Park was funded by the United Nations Institute for Training and Research (UNITAR) and Swiss Confederation, and organized by NANOTEC and NSTDA. The workshop was held in conjunction with the NSTDA Annual Conference 2013 (NAC 2013). Speaking on behalf of Swiss Confederation, Mrs. Daniela Schneider extended her gratitude to the Thai government for their leadership in promoting public awareness to the emerging issue of nano technology and manufactured nano materials. “Thailand has set an important example in the Asian region by creating an agency to coordinate the management of nanotechnology at a national level” said Daniela. “We believe that Thailand has the potential to take a leading role in this exciting new area at the regional or sub-regional level and we are willing to support such sub-regional collaboration”. Also echoing Daniela’s comment is Mr. Georg Karlaganis, Training Advisor, Chemicals and Waste Management Program, United Nations Institute for Training and Research (UNITAR) who said that in the field of nano safety management Thailand is ahead compared to others. He went on to say that the public engagement activities in Thailand set a good introductory example for other countries to follow. This is not the first time that the 4 organization have join force to organize a public engagement activity. In 2012 a public seminar was held in Khon Kaen province during NanoThailand 2012 to address the topic of “Society, Nanosafety and Ethics on Nanotechnology Development”. The various nanosafety workshops that have been organized by the 4 organization in the past stemmed from the signed 2011 NANOTEC- UNITAR Memorandum of Agreement to implement a Training and Capacity Building for the Development of the Nano-Safety Pilot project in Thailand (phase 1). Based on the positive results of the phase 1 project and from the clear message of SAICM ICCM3 Nairobi meeting, UNITAR & Swiss Confederation have decided to continue support for a second phase of the nano pilot projects with NANOTEC.

|With the increase in nano related products in the market and the establishment of the Asean Economic Community (AEC) in 2015, the question of safety becomes an even bigger concern for the consumer. In a recent Asian-Pacific Newsletter on Occupational Health and Safety (Vol 19, number 3, December 2012), Prof. Sirirurg Songsivilai, NANOTEC Executive Director emphasized that the number of products currently on the market containing nanomaterials as the critical component or uses nanotechnology in crucial manufacturing process will increase from 1% to 10% in the coming decade. This is a significant increase and one which needs public attention as this may have impact on everyday life. To give priority to this topic, NANOTEC joined the NSTDA Annual Conference 2013 (NAC 2013) to organize a seminar at Thailand Science Park under the theme “Nano-Characterization and Testing Service for AEC”. The seminar looks at nanoscale analytical testing, regulations of nanoproducts, testing techniques, metrological at nanoscale, and the approach to using NanoQ in Thailand. Over 150 participants from public, academia, and private sector attended the seminar.|
|“The AEC landscape is quite complex given the fact that there are more people, more competition, more movement of capital and technology, and more movement of human resources” said Dr. Chainarong Cherdchu, Senior Advisor at NANOTEC. “The importance of having conformity of standards and quality especially in measurement will be an important topic once AEC comes of age. Therefore, it is necessary that we all become aware and understands exactly what is involved”. NanoQ label also took front stage with a presentation by Mr. Por Punyaratabandhu, Chairman of NanoQ Label, Nanotechnology Association of Thailand. The talk entitled “The Practical Approach: NanoQ” provides information on the benefits of NanoQ label to 4 private sector groups: ceramic, plastic, textile, and paints. The first NanoQ label was presented in September 2012 to Supreme Products Co.,Ltd. The NanoQ label certified that the paint formulation produced by Supreme Product for use in coating the inside of the ambulance contains silver nano particles that have characteristics of anti bacteria. The testing of the paint formulation samples was performed by researchers at Nano Characteristic Lab at NANOTEC. This certification is good for 2 years. Since then, the association has received interest from various companies inquiring about the application for NanoQ label for their product. [gallery link="file" columns="2"]|
The 3rd Thailand – Korea Nanobiotechnology Joint Research Meeting opened this morning with Prof. Sirirurg Songsivilai, NANOTEC Executive Director presenting the Opening Remarks. According to Prof. Sirirurg the meeting provides a venue for interaction and mixing between nanobiotechnology researchers that will create the research sparks that the local research community needs. Prof. Sirirurg gestured a symbolic comparison of the gathering to that of the late Steve Jobs push for human interaction and creativity at his Pixar Animation Studio in the USA. Prof. Sirirurg told the story of the 2 bathrooms at Steve Jobs’ Pixar Animation studio. According to Prof. Sirirurg, Steve Jobs insisted there be only two bathrooms in the entire Pixar studios, and that these would be in the central space. And of course this is very inconvenient. No one wants to have to walk 15 minutes to go to the bathroom. And yet he insisted that this is the one place everyone has to go every day. If you do happen to visit Pixar, ask them about their 'bathroom story.' They all talk about the great conversation they had while washing their hands. He went on to say that Steve Jobs wanted there to be mixing. He knew that the human friction makes the sparks, and that when you're talking about a creative endeavor that requires people from different cultures to come together, you have to force them to mix; that our natural tendency is to stay isolated, to talk to people who are just like us, who speak our private languages, who understand our problems. But that's a big mistake. And so his design was to force people to come together even if it was just going to be in the bathroom. Leading the Korean team was Dr. Bong Hyun Chung, Director of BioNanotechnology Research Center, Korea Research Institute of Bioscience and Biotechnology (KRIBB). “The field of convergence is one of the key engines for economic growth and creation of jobs under the new government” said Prof. Chung. “When there is successful commercialization of new technology, this helps to contribute to the economy of any nation”. Prof. Chung went on to inform that the new Korean government has assigned science and technology portfolio to be under the Ministry of Future, Creation and Science (MFCS). The new ministry will be involved in promoting investment in research and development. The 3 days meeting from March 29-31 in Bangkok is organized by NANOTEC and KRIBB to promote research collaboration opportunities between Thailand and Korea. A total of 25 experts took turn to present technical papers and exchange dialogue on selected research projects. In addition, the program also included the Networking and Discussion session on 4 themes: Nanomedicine, NanoSafety, and NanoBiosensor. The 4th meeting in 2014 will take place in Korea hosted by KRIBB. [gallery link="file" columns="2"]
