• Mystery of two-dimensional quasicrystal formation from metal oxides solved
  

  The structure of two-dimensional titanium oxide brakes-up at high temperatures by adding barium; instead of regular hexagons, rings of four, seven and ten atoms are created that order aperiodically. A team at Martin Luther University Halle-Wittenberg (MLU) made this discovery in colaboration with re more

• Efficient, stable, and eco-friendly thermoelectric material discovered
  

  Waste heat is a very promising source of energy conservation and reuse, by means of converting this heat into electricity—a process called thermoelectric conversion. Commercially available thermoelectric conversion devices are synthesized using rare metals. While these are quite efficient, they are more

• Demonstrating Feshbach resonances between a single ion and ultracold atoms
  

  A team led by Prof. Dr. Tobias Schätz, Professor of Atomic and Quantum Physics at the Institute of Physics at the University of Freiburg, Dr. Pascal Weckesser, Fabian Thielemann and colleagues, demonstrate magnetic Feshbach resonances between a single barium ion and lithium atoms at near absolute ze more

The Chemistry of Sparklers

It’s Fireworks Night here in the UK tomorrow, which means fireworks (obviously), bonfires and sparklers. We’ve looked at fireworks in a previous post, so this time around it’s time to take a look at the chemicals that go into producing sparklers, and their various roles. In sparklers, there are thre more

Metal Ion Flame Test Colours Chart

This graphic looks at the colour of various metal and metalloid ions that occur during flame tests. Most people probably remember doing this experiment in school chemistry lessons, if not with the full range of ions shown here, but for the uninitiated a brief explanation of the origin of the colours more

The Dark Side of Fireworks

Many of us enjoyed watching spectacular fireworks displays to usher in the new year. However, the vibrant colours of fireworks belie the effects that they can have on the environment. With this graphic, we take a look at some of the issues that they can cause. more
