Images of ZnO Nanotubes are selected as one of the cover images of Applied Physics Letters (APL) highlighted in the APL 50th anniversary celebration website. The related article, “Formation of Single Crystalline ZnO Nanotubes without Catalysts and Templates,” was the most read article in March 2007. The images and article are from Professor Yoke Khin Yap’s research group.
Recent work on in-situ probing of individual boron nitride nanotubes by scanning tunneling microscopy (STM) inside a transmission electron microscopy (TEM) system is being featured in NanotechWeb. The research is conducted by Hessam M Ghassemi and Reza S Yassar in the mechanical engineering-engineering mechanics department and Chee Hui Lee and Yoke Khin Yap in the physics department. NanotechWeb notes that BNNTs are unique materials which enable the study of band structure modulation by mechanical straining. “This may lead to rational control of the electrical properties of novel nanostructures in the future,” commented Yoke Yap.
Researchers from the Multiscale Technologies Institute (MuSTI) gained noticeable attention in the 2011 Materials Research Society Fall Meeting, held Nov. 27 to Dec. 2 in Boston. Professor Yoke Khin Yap (Physics) was the lead organizer of “Symposium AA: Carbon Nanotubes, Graphene, and Related Nanostructures.” This symposium attracted about 450 contributed papers and 22 invited lectures and was the largest symposium of the 47 in the meeting.
A story on “Nanotech: Injections Or Sampling? New ‘Molecular Syringes’ Under Testing” based on Siegfried Höfinger’s research has been picked up by several news outlets, such as Science Newsline Technology, Nanotechnology Now, and ScienceDaily. Höfinger is a research fellow with the Dipartimento di Chimica “G. Ciamician,” Universita di Bologna, and an adjunct assistant professor with the Department of Physics at Michigan Tech. The research involves free energy calculations of membrane insertion of individual carbon nanotubes and carbon nanotube bundles, published as Siegfried Höfinger, Manuel Melle-Franco, Tommaso Gallo, Andrea Cantelli, Matteo Calvaresi, José A.N.F. Gomes, Francesco Zerbetto. A computational analysis of the insertion of carbon nanotubes into cellular membranes. Biomaterials, 2011; DOI: 10.1016/j.biomaterials.2011.06.011

Michigan Technological University scientists Yoke Khin Yap and Jaroslaw Drelich have created a filter that separates the two substances as quickly and cleanly as a ref breaking up a clinch. Their work was published in the Feb. 2 edition of the journal Carbon and is funded by the National Science Foundation. READ MORE
Vertically-aligned carbon nanorods co-developed by Professor Yoke Khin Yap are being featured on the cover of Carbon (issue 49/8, July 2011). These nanorods contained nitrogen donors and will have enhanced electrical and electrochemical properties as compared to pure carbon nanomaterials. They were self-assembled into vertical arrays as induced by the applied electric fields and the incorporation of polarized isonitrile bonds [–N≡C] during the plasma-enhanced chemical vapor deposition (PECVD) process. This work was conducted in the University of Malaya when Professor Yap was on his sabbatical visit during Jan-May 2009. The related article was published by Ritikos et al. in issue 49/6 (May 2011) of the journal. Carbon is a journal published by Elsevier with an impact factor of 4.5.
Michigan Tech Research Magazine 2011 has three features on physics research this year. Left is Ranjit Pati, whose research team built a molecular computer using lessons learned from the human brain. In the middle are David Nitz and Brian Fick, who are corecipients of Michigan Tech’s 2010 Research Award in the fields of experimental particle physics and ultrahigh energy cosmic rays. On the right are boron nitride nanotubes representing the precision experimental work of Yoke Khin Yap and his research team.

Who ever would have guessed that the business end of Dixon Ticonderoga No. 2 pencils would someday be the next big thing?
John Jaszczak, perhaps. He was not all that surprised that the 2010 Nobel Prize in Physics was presented to two Russian-born scientists who created atom-thin sheets of carbon, called graphene, made from graphite. Jaszczak, a professor of physics and adjunct curator of the Seaman Mineral Museum, is a longtime fan of the mineral and was familiar with their prize-winning work. In fact, he supplied the researchers, Andre Geim and Konstantin Novoselov of the University of Manchester, with graphite crystals to use in their experiments. And, he appears as a coauthor on one of their papers, “Giant Intrinsic Carrier Mobilities in Graphene and Its Bilayer,” published in Physical Review Letters.
