• Secret messages hidden in light-sensitive polymers
  

  DNA is a long chemical sequence that carries genetic information. Inspired by this biological system, in recent years many research teams have been exploring how to store and then decode information within synthetic macromolecules, also called polymers. In a leap forward in this field, researchers a more

• Researchers have discovered how a nanocatalyst works at the atomic level
  

  The researchers of the Nanoscience Center (NSC) at the University of Jyväskylä, Finland, and in the Xiamen University, China, have discovered how copper particles at the nanometre scale operate in modifying a carbon-oxygen bond when ketone molecules turn into alcohol molecules. Modification of the c more

• Decoupled graphene thanks to potassium bromide
  

  The use of potassium bromide in the production of graphene on a copper surface can lead to better results. When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. This alters the electrical properties of the graphene produced, bringing th 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
