• Double-walled nanotubes have electro-optical advantages
  

  One nanotube could be great for electronics applications, but there's new evidence that two could be tops. Rice University engineers already knew that size matters when using single-walled carbon nanotubes for their electrical properties. But until now, nobody had studied how electrons act when conf more

• Growing carbon nanotubes with the right twist
  

  In a recently published paper in Science Advances, Feng Ding of the Center for Multidimensional Carbon Materials, within the Institute of Basic Science (IBS, South Korea) and colleagues, have achieved the creation of a specific type of carbon nanotubes (CNTs) with a selectivity of 90%, and expanded more

• Solving the thermoelectric 'trade-off' conundrum with metallic carbon nanotubes
  

  Scientists from Tokyo Metropolitan University have used aligned "metallic" carbon nanotubes to create a device which converts heat to electrical energy (a thermoelectric device) with a higher power output than pure semiconducting carbon nanotubes (CNTs) in random networks. The new device bypasses th more

"Evolving electronics" could lead to new electrical devices

Scientists at Durham University, UK, have “taught” materials to form electrical pathways in order to solve a simple problem, which could eventually lead to new electronic devices.Taking their inspiration from nature, where living organisms evolve to perform complex tasks, the researchers trained ... more

Carbon nanotube transistors outperform silicon for first time ever

In a world first, a team of University of Wisconsin-Madison materials engineers have created carbon nanotube transistors that outperform state-of-the-art silicon transistors.A big milestone for nanotechnology, this breakthrough could enable longer battery life, faster wireless communication and ... more

Graphene

You may not have been aware, but this week is Graphene Week 2015, which marks a yearly week-long conference at the University of Manchester based around the emerging science and technological applications of graphene. This seemed as good a time as any to take a look at graphene: what it is, why some more

Nanotechnology Day & Everyday Uses of Nanotechnology

October 9 is National Nanotechnology Day in the US, as it’s 10/9 in the American date format (and one nanometre is 10–9 metres). This month’s edition of Periodic Graphics in C&EN takes a look at a selection of the nanotechnology that’s already made its way into our everyday lives. more

• Cobalt entrenched N-, O-, and S-tridoped carbons as efficient multifunctional sustainable catalysts for base-free selective oxidative esterification of alcohols

  We report the synthesis of sustainable and reusable non-noble transition-metal (cobalt) nanocatalysts containing N-, O-, and S-tridoped carbon nanotubes (Co@NOSC) composites. The inexpensive and benign carrageenan served as carbon, oxygen, and sulfur source, while urea supplied the nitrogen componen more

• Synthesis and organic solar cell performance of BODIPY and coumarin functionalized SWCNT or graphene oxide nanomaterials

  The synthesis and characterization of new hybrid materials based on reduced graphene oxide (rGO) or single walled carbon nanotubes (SWCNTs) covalently functionalized by 4,4-difluoro-8-(4-propynyloxy)-phenyl-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene (BODIPY) (2) or 7-(prop-2-yn-1-yloxy)-3-(3, more

• A highly sensitive glucose sensor based on a gold nanoparticles/polyaniline/multi-walled carbon nanotubes composite modified glassy carbon electrode

  An amperometric glucose sensor, PTFE/GOx/AuNPs/PANI/MWCNTs/GCE, was assembled layer-by-layer using multi-wall carbon nanotubes (MWCNTs), polyaniline (PANI), and gold nanoparticles (AuNPs) for electrode surface modification and a fixed glucose oxidase enzyme (GOx) carrier. Methods such as cyclic volt more
