Chemists have synthesized a highly selective and highly efficient zirconium catalyst that makes new carbon-nitrogen bonds by adding a nitrogen-hydrogen bond to a carbon-carbon double bond. Nitrogen-containing chemicals are important as agrichemicals, pharmace
A material that is magnetic, superconducting and behaves nearly like a semiconducting sounds fairly unusual, and it is. Just such a material, made from potassium, iron and selenium, was recently discovered. It has similar superconducting properties to iron-arsenide-based superconductors. However, it is also nearly semiconducting and, most curious, has a very high (antiferro-)magnetic ordering temperature with large (rather than small) magnetic moments.
A novel electrode architecture has led to a new way to make transparent electrical contacts. Typical ways of attaching a conductor to a non-metallic material allow you to see the electrode. However, for many applications, like light emitting diode (LED) displays, smart windows and solar cells, transparency to visible light is a requirement that conflicts with electrical conductance. Thinner films are more transparent, but less conductive. The new architecture consists of specially patterned nanoscale-thick metallic ribbons, standing on edge, supported by a polymer matrix.
Researchers have wrestled with the question of whether or not the newest superconducting materials fit within the traditional classifications. Superconductors can be divided into Type 1 and Type 2, depending on how they behave in a magnetic field. However, magnesium diboride was discovered to have characteristics of both categories and has been dubbed “Type 1.5”.
