• How nitrogen is transferred by a catalyst
  

  Catalysts with a metal-nitrogen bond can transfer nitrogen to organic molecules. In this process short-lived molecular species are formed, whose properties critically determine the course of the reaction and product formation. The key compound in a catalytic nitrogen-atom transfer reaction has now b more

• Reducing Nitrogen with Boron and Beer
  

  The industrial conversion of nitrogen to ammonium provides fertiliser for agriculture. Würzburg chemists have now achieved this conversion at room temperature and low pressure using only light elements. Humankind is reliant on the ammonium in synthetic fertiliser for food. However, producing ammoni more

• Nitrogen – an exception in the periodic system?
  

  In the periodic table of elements there is one golden rule for carbon, oxygen, and other light elements. Under high pressures they have similar structures to heavier elements in the same group of elements. Only nitrogen always seemed unwilling to toe the line. However, high-pressure researchers of t more

The Chemistry of Diamond Rings

Diamonds might purportedly be ‘a girl’s best friend’, but they’re also quite interesting from a chemical perspective. You could be forgiven for thinking that there’s not a whole lot to them; after all, they’re simply one of the possible forms of carbon, formed at high pressure beneath the Earth’s su more

Group 5 Elements

The latest of the element infographics looks at the Group 5 elements. There is, once again, an interesting fact that I couldn’t quite fit in, or left out at the expense of others: Bismuth-209 was long thought to have heaviest stable nucleus of any element, until 2003 when it was determined by French more

The Atmospheres of the Solar System

We’re heading out of this world for today’s post, to examine the atmospheric compositions of the other planets in the solar system, as well as our own. Practically every other planet in our solar system can be considered to have an atmosphere, apart from perhaps the extremely thin, transient atmosph more

• Nitrogen enriched polytriazine as metal-free heterogeneous catalyst for the Knoevenagel reaction in mild condition

  Nitrogen enriched (52 wt %) nanoporous polytriazine with high specific surface area up to 850 m2 g-1 is synthesized by an ultrafast (30 min reaction time) microwave assisted route using inexpensive precursors cyanuric chloride and melamine at 400 W. The metal-free highly electron rich material is us more

• Nitrogen-enriched Carbon Spheres Coupled with Graphitic Carbon Nitride Nanosheets for High Performance Supercapacitors

  Three-dimensional (3D) nitrogen-doped carbon materials with hierarchically porous structure are prepared by the introduction of nitrogen-doped carbon spheres (NCS) into the inter-sheets space of graphitic carbon nitride nanosheets (g-CN). The as-prepared graphitic carbon nitride/nitrogen-doped carbo more

• Implementation of a logic gate by chemically induced nitrogen and oxygen rich C-dots for the selective detection of fluoride ions

  The widespread pollution of fluoride ions in the environment badly affects the ecological system due to their high toxicity, mobility and the difficulty of their degradation. So, there is a need to design an environmentally friendly, highly selective and sensitive probe for their detection. Here, we more
