• Copper ion unlocks magnesium's potential in next-generation battery
  

  Researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have come a step closer to making a viable, high-output battery based on magnesium (Mg), an element the United States Geological Survey reports is far more abundant than lith more

• Lighting material of the future
  

  At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale - that means it is practically made for use in large-area room lighti more

• Honey, I shrunk Michelangelo's David
  

  There he is, standing upon his pedestal: David by Michelangelo. A world-​famous statue that nearly every child can recognise. But this David is just 1 millimeter tall, pedestal included, and is made not of marble like the 5.17-​meter original, but of pure copper. It was created using 3D printing by more

The Composition of the Rio Olympics Medals

If you’ve been watching the Olympics, you might have assumed that the medals given out are, as advertised, made of gold, silver, and bronze. Due to metal values, however, the reality is slightly more complicated. Giving out pure gold medals would be financially crippling for the International Olympi more

The Compositions of U.S. Coins

In this month’s Periodic Graphics in Chemical & Engineering News magazine, we’re looking at the compositions of U.S. coins, as well as some of their quirky history. more

The Metals in UK Coins

In the wake of the recent announcement of a new £1 coin to be introduced in 2017, today’s post looks at some of the metals present in the coins of the United Kingdom. All of these coins are produced using alloys, or mixtures of metals; the main metals used include copper, nickel, zinc and iron. The more

• Copper-Catalyzed Cyclization of 2-Cyanobenzaldehydes and 2-Isocyanoacetates: an Efficient Strategy for the Synthesis of Substituted 1-Aminoisoquinolines

  A Cu(acac)2-catalyzed cyclization reaction of 2-cyanobenzaldehydes with 2-isocyanoacetates has been successfully developed providing an efficient strategy for the synthesis of substituted 1-aminoisoquinoline. The reaction proceeds smoothly under mild conditions with high efficiency, and might provid more

• Precursor-mediated synthesis of Cu2−xSe nanoparticles and their composites with TiO2 for improved photocatalysis

  The direct synthesis of copper selenide nanoparticles from the reaction of ditertiarybutyl selenide tBu2Se with copper(ii) trifluoroacetate Cu(TFA)2 under mild conditions is reported. The isolation of a molecular species during the course of this reaction, established as [Cu2(TFA)2(tBu2Se)3], by spe more

• A bifunctional cationic metal–organic framework based on unprecedented nonanuclear copper(II) cluster for high dichromate and chromate trapping and highly efficient photocataly ...

  A bifunctional cationic metal–organic framework {[Cu9(OH)6Cl2(itp)6(1,4-bdc)3](NO3)2(OH)2·20H2O}n (1-NO3-OH·20H2O) was synthesized and characterized (itp = 1-imidazol-1-yl-3-(1,2,4-triazol-4-yl)propane, 1,4-bdc = 1,4-benzenedicarboxylate). In 1-NO3-OH·20H2O, three [Cu3(μ3-OH)(μ2-OH)] trimeric cluste more
