• From trash to treasure: Silicon waste finds new use in Li-ion batteries
  

  Li-ion batteries (LIBs) are widely used in various mobile electronics. Concerns of global warming and climate change have recently boosted the demand for LIBs in electric vehicles and solar photovoltaic output smoothing. Si has been studied as an active material with a high theoretical capacity of 3 more

• Researchers turn coal powder into graphite in microwave oven
  

  Using copper foil, glass containers and a conventional household microwave oven, University of Wyoming researchers have demonstrated that pulverized coal powder can be converted into higher-value nano-graphite. The discovery is another step forward in the effort to find alternative uses for Wyoming' more

• Old Mystery Solved: a "New Kind of Electrons"
  

  It is something quite common in physics: electrons leave a certain material, they fly away and then they are measured. Some materials emit electrons, when they are irradiated with light. These electrons are then called "photoelectrons". In materials research, so-called "Auger electrons" also play an 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

Why Lithium-Ion Batteries Catch Fire

In this month’s Periodic Graphics in C&EN, we’re looking at the chemistry behind the recent news stories of lithium-ion batteries in some devices catching fire. You can see the full graphic over on the C&EN site. Also, for more lithium battery chemistry, head over to the recent RealTimeChem Week gra more

Developing Advanced Lithium Ion Batteries

Today’s graphic takes a look at the research of Kent Griffith (@kentjgriffith), a PhD student from the University of Cambridge who’s currently looking into developing advanced lithium ion batteries to power our phones, laptops, and more. more
