• Stepstone for sustainable batteries – greener carbons
  

  Lithium-ion batteries require in addition to lithium metal a number of sophisticated functional materials for their performance. Some of them sound rather unspectacular: conductive additives. In fact, conductive additives like carbon black or carbon nanotubes are a decisive component for the perform more

• Optically Active Defects Improve Carbon Nanotubes
  

  The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural “imperfections” or defects. The challenge, however, is to control the number and type of these defects. In the case of carbon nanotubes – microscopically small tubular more

• Scientists grow carbon nanotube forest much longer than any other
  

  Today, a multitude of industries, including optics, electronics, water purification, and drug delivery, innovate at an unprecedented scale with nanometer-wide rolls of honeycomb-shaped graphite sheets called carbon nanotubes (CNTs). Features such as light weight, convenient structure, immense mechan 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
