• When boron butts in

  For Nature and chemists alike, making atmospheric nitrogen available for the formation of more complex nitrogen compounds is both essential and difficult. Paul Chirik and Scott Semproni at Princeton University, USA, report the first examples of the use of group 4 metallocene complexes for boron–nitr more

• Bonn physicists create a 'super-photon'

  Physicists from the University of Bonn have developed a completely new source of light, a so-called Bose-Einstein condensate consisting of photons. Until recently, expert had thought this impossible. This method may potentially be suitable for designing novel light sources resembling lasers that wor more

• New ultra-clean nanowires have great potential

  New ultra-clean nanowires produced at the Nano-Science Center, University of Copenhagen will have a central role in the development of new high-efficiency solar cells and electronics on a nanometer scale. PhD student Peter Krogstrup, Niels Bohr Institute, in collaboration with a number of well-known more

• Size and element specific determination of Ag nanoparticles in consumer spray products using asymmetric flow field flow fractionation (AF4) coupled to ICPMS
  

  The use of nanoparticles in consumer products shows a tremendous increase over the past years. A study of the Woodrow Wilson International Centre for Scholars reported that between 2005 and today the number of products based on nanoparticles increased almost twentyfold from 54 to 1015. As active compounds these products contain ZnO for surface protection, TiO2 for sun screen or Ag for anti-bacterial purposes, only to name a few applications. Furthermore, Si, C and Au are frequently used. So far, no data are available concerning the release and the behaviour of nanoparticles during the spray process. Therefore, in spite of their beneficial properties, possible risks for humans and the environment need to be thoroughly investigated. Especially the exposure pathway via the lung seems to be very critical, as could be shown in a study recently published in the Journal of Nanoparticle Research more

• The Danger of Air & Bubbles

  Air and bubbles, or fluid aeration and cavitation, can cause numerous problems in a hydraulic and lubrication oil system. Lubrication practitioners should be attentive to abnormal noise, poor component response due to spongy behavior of aerated fluids and high fluid temperature as signs of poor lubricant health more

• Measuring particle size using modern laser diffraction techniques
  

  Many different techniques have been devised for determining particle size distribution, but for a wide range of industries laser diffraction has become the preferred choice. Laser diffraction, alternatively referred to as Low Angle Laser Light Scattering (LALLS), can be used for the non-destructive analysis of wet or dry samples, with particles in the size range 0.02 to 2000 micron and has inherent advantages which make it preferable to other options for many different materials. more

• Enantioselective self-assembly of antiferromagnetic hexacopper(II) wheels with chiral amino acid oxamates

  The Cu2+-mediated self-assembly of oxamato-based ligands derived from either the (S)- or (R)-enantiomers of the amino acid valine leads to the formation of two antiferromagnetically coupled homochiral anionic hexacopper(II) wheels under the presence of templating tetramethylammonium countercations. more

• A simply and novel synthesis of 3-(thio)phosphoryl-[small beta]-lactams by radical cyclization

  Radical cyclization of phosphono-acetenamides promoted by manganese (III) acetate leads exclusively to the formation of 3-phosphoryl-β-lactams. The thiophosphoryl analogues were also prepared using this method. In particular, the presented protocol doesn’t require the use of nobel metals, while comp more

• Ln[N(SiMe3)2]3-catalyzed cycloaddition of terminal alkynes to azides leading to 1,5-disubstituted 1,2,3-triazoles: new mechanistic features

  The first example of rare earth metal-catalyzed cycloaddition of terminal alkynes to azides resulting in the formation of 1,5-disubstituted 1,2,3-triazoles is described. Preliminary studies revealed that the present cycloaddition shows unprecedented mechanistic features involving a tandem anionic ca more

• Polymer Market in India 2012

  Indian Petrochemical industry is one of the fastest growing sectors in the world. Low operating capacities in Indian petrochemical concerns bring with it the opportunity for future facility utilization. Polymer market is dependent on growth in related sectors. Low per capita consumption of polymer o more

• Colombia Agribusiness Report Q3 2012

  BMI View: In May, the long-stalled free trade agreement (FTA) between Colombia and the US finally was put into action. The FTA was first signed in 2006 but had not been ratified owing to continuing concerns in the US over Colombia's human rights record. The pact eliminates tariffs on 77% of agricult more

• Spain Petrochemicals Report Q1 2012

  Aggressive fiscal austerity, rising interest rates, stubbornly high unemployment and ongoing deleveraging within the private sector will keep petrochemicals output and consumption well below potential over the medium term, according to BMI’s latest Spain Petrochemicals Report. With the domestic ma more
