Crystalline 'artificial muscle' makes paper doll do sit-ups

Scary movies about dolls that can move, like Anabelle and Chucky, are popular at theaters this summer. Meanwhile, a much less menacing animated doll has chemists talking. Researchers have given a foil "paper doll" the ability ...

Solubility mystery of widely-used plastic solved

Polyether molecules tend to dissolve better in water as they contain more oxygen and fewer carbon atoms. But there are very counter-intuitive exceptions to this trend, the most well-known being the widely used plastic POM. ...

Now you see heat, now you don't

Hiding an object from heat-sensing cameras could be useful for military and technology applications as well as for research. Efforts to develop such a method have been underway for decades with varying degrees of success. ...

'Frozen' copper behaves as noble metal in catalysis: study

As a non-noble metal, copper oxidizes more easily to a positive valence (Cu+ or Cu2+) than same-family elements Au or Ag. In general, this chemical property is mainly determined by electron structure. Can we change the chemical ...

Liquid crystals and the origin of life

The display screens of modern televisions, cell phones and computer monitors rely on liquid crystals—materials that flow like liquids but have molecules oriented in crystal-like structures. However, liquid crystals may ...
