MIT awarded UNESCO Medal for contributions to nanoscience and nanotechnologies

InterNano Industry News - March 22, 2017 - 3:45am
MIT has been honored with the UNESCO Medal for contributions to the development of nanoscience and nanotechnologies by the United Nations Educational, Scientific and Cultural Organization (UNESCO). Established in 2010, the UNESCO Medal has awarded over 30 prominent scientists and public figures for their individual contributions to advancing the fields of nanoscience and nanotechnologies. This year MIT shares the distinction, along with St. Petersburg State University of Information Technologies in Russia, of being the first organization to be recognized. In addition to the two universities, four eminent scientists from Korea, the United Arab Emirates, Ukraine, and the United Kingdom, were recipients of the medal. An awards ceremony was held on Oct. 11 at the UNESCO headquarters in Paris, France. Institute Professor Mildred (Millie) Dresselhaus, a nanoscience pioneer who herself has won many recognitions including the U.S. Presidential Medal of Freedom and the L'Oreal-UNESCO Award for Women in Science, made the trip at the invitation of President Rafael Reif to accept the medal on behalf of MIT. “Using science and technology as a way to bring people together is something MIT has learned to do really well,” says Dresselhaus. “Our faculty, staff, and students come together from countries all over the world with diverse technical backgrounds to work across the many academic departments and laboratories on campus. This culture of interdisciplinary collaboration enables us to work for common goals, so it made sense to me that MIT was recognized as an institution. This should serve as encouragement to move forward as rapidly as possible to complete MIT.nano and to achieve some exceptionally great outcomes through this initiative as it comes to fruition.” The award will eventually be displayed within the public spaces of MIT.nano — the 214,000-square-foot center for nanoscience and nanotechnology that is currently under construction in the heart of the MIT campus — after the building opening in June 2018, says Vladimir Bulović, faculty lead of the project. The UNESCO Medal is an initiative of the International Commission responsible for developing the Encyclopedia of Life Support Systems theme on nanoscience and nanotechnologies. Each year, the medal recognizes those making significant contributions in the field in an effort to showcase the tremendous benefits of progress being made. MIT joins a distinguished group of scientists who have received the medal thus far, including Nobel Prize-winners in physics Zhores Alferov and Isamu Akasaki.

An economical solution for the removal of selenium contaminants in wastewater

InterNano Industry News - March 22, 2017 - 3:45am
Selenium (Se) is a metalloid element found in trace amounts in the earth’s crust and which has found extensive application due to its semiconducting properties. The use in photocopiers, microelectronic circuits and other applications has created a demand which makes selenium a valuable element. Selenium also shows biological activity with a strong dependence on concentration: it is essential in low doses for mammalian organisms but becomes strongly toxic to humans over a certain intake threshold. Efficient removal of selenium from wastewater being discharged in the environment is imperative and the development of cost-effective procedures to achieve this needs to be addressed. Under typical environmental conditions Se can be found in a variety of oxidation states (-II, 0, IV, and VI). The former two are insoluble and give rise to little toxicity on account of their low mobility in aqueous phases. The latter two however are found as highly mobile oxyanions which are the principal targets for Se removal. Finding the right reagent Ling et al have used an established strategy involving the reduction of Se(IV) to the insoluble Se(0) form, but their choice of nanoscale zero-valent iron (nZVI) as the reagent has led to a superior method of wastewater decontamination being developed. As little as 0.2 g L-1 nZVI can achieve over 99% removal of high levels of Se(IV) within 5 hours. Additionally, on account of the magnetic properties of the nZVI its recovery could be achieved simply with the use of a magnet, leaving pure elemental selenium as the product. The potential for elemental selenium recovery and recycling provides grounding for the method becoming cost-neutral or even profitable. Furthermore, in depth studies were conducted to elucidate the pathway taken by the decontamination process, with attention focused on the nano- and microstructure of the resulting Se particles and of the nZVI before and after reaction. The nZVI particles consist of a metallic iron core surrounded by an oxide layer which under aqueous conditions is capable of performing adsorption of Se oxyanions, thus paving the way for their reduction by the metallic core. Two types of Se structures result following the reductive process: almost perfectly spherical nanoparticles and nano-needles, both being attributed to known forms of elemental Se: amorphous and trigonal, respectively. A complete account of the Se(IV) reduction and Se(0) structure formation mechanisms operating in this process is available in the full article, free to view for a limited time:* Genesis of pure Se(0) nano- and micro-structures in wastewater with nanoscale zero-valent iron (nZVI) Environ.

Connecting two electrodes by liquid crystal-guided carbon nanotube wires

InterNano Industry News - March 22, 2017 - 3:45am
Carbon nanotubes (CNTs) being highly electrically conductive along the tube axis, have gained great research interests in recent years for connecting two conducting electrodes at the nanoscale - where the CNTs can be integrated into a micro- or nanoelectronic system. Therefore, the orientational control of CNTs has drawn a great deal of research interest in nanotechnology. Researchers now have developed a technique to bridge two electrical conductors by assembling CNTs guided by liquid crystals.
