  • Small is different

    In the production of margarine millions of tons of unsaturated fatty acids are converted from vegetable oils using hydrogen. While searching for improved catalysts for these so-called hydrogenation reactions, a German-American research team made a discovery that puts a 50-year old rule in question: more

  • Soil crusts emit nitrogen oxides and nitrous acid

    For a long time now, researchers have been racking their brains over the large quantities of reactive nitrogen compounds observed in arid regions after periods of rainfall without being able to identify the source. A study is now bringing light into the darkness. Bettina Weber and her colleagues fro more

  • Evonik plans to build additional world-scale methionine plant

    Evonik Industries has started the planning stage for the construction of an additional world-scale plant complex in Singapore. The facility, which will produce the amino acid DL-methionine for animal nutrition, will have an annual production capacity of 150,000 metric tons and is expected to start o more

  • Taking Bismuthinite to Bismuth Sulfide Nanorods in Two Easy Steps

    The transformation of mineral bismuthinite, to Bi2S3 nanoparticles, via a simple two-step process is described. The reaction of bismuthinite with two aryldithoic acids gave the complexes; [Bi(S2C(C6H4)-4-CH3)3] and [Bi(S2C(C6H4)-4-OCH3)3]. Mild solution decomposition (120 °C) of these bismuth aryldi more

  • Efficient one-pot synthesis of 1-arylcycloprop-2-ene-1-carboxamides

    An expeditious and cost-efficient method for synthesis of 1-aryl-cycloprop-2-ene-1-carboxamides was developed. This one-pot protocol involving coupling of amines with acyl chlorides, generated upon treatment of cyclopenylcarboxylic acids with oxalyl chloride, is applicable for the preparation of sen more

  • Tuning the flexibility in MOFs by SBU functionalization

    A new approach for the fine tuning of flexibility in MOFs, involving functionalization of the secondary building unit, is presented. The “gate pressure” MOF [Zn3(bpydc)2(HCOO)2] was used as a model material and SBU functionalization was performed by using monocarboxylic acids such as acetic, benzoic more
