• Cheap, simple and efficient molybdenum carbide electrocatalysts for hydrogen production

  US scientists have made an efficient catalytic system to split water that uses molybdenum carbide nanoparticles on a carbon nanotube support. Molybdenum and carbon are both low cost and abundant elements. Water splitting using sustainable energy sources, such as solar and wind power, has been identi more

• Breakthrough in designing cheaper, more efficient catalysts for fuel cells
  

  University of California, Berkeley, chemists are reimagining catalysts in ways that could have a profound impact on the chemical industry as well as on the growing market for hydrogen fuel cell vehicles. Catalysts are materials typically metals that speed up chemical reactions and are widely used in more

• Berkeley scientists discover inexpensive metal catalyst for generating hydrogen from water

  Hydrogen would command a key role in future renewable energy technologies, experts agree, if a relatively cheap, efficient and carbon-neutral means of producing it can be developed. An important step towards this elusive goal has been taken by a team of researchers with the U.S. Department of Energy more

• Particle Analysis: Quality Control of Catalysts with Digital Image Processing
  

  Catalysts are widely used as an important auxiliary material in the chemical and petrochemical industry. They are able to accelerate chemical reactions by lowering the activation energy, i.e. they change reaction kinetics. Thus, using catalysts in industrial processes has the advantage of higher productivity combined with less energy consumption. more

• The Determination of Hazardous Substances According to RoHS and WEEE Directives
  

  1st July 2006 is an important deadline for the electro- and electronics industries. This date bans hazardous substances like lead, cadmium, mercury, hexavalent chromium and polybrominated biphenyls and diphenyl ethers from electro- and electronic equipment. This restriction, even though in discussion since 1991, has become more and more important from year to year because of tons of electronic waste releasing toxic substances which are accumulated in the environment, the food chain and all human beings. In order to enforce the substances ban and the limitation or substitution of hazardous components, elemental analysis is obviously the most important control measure for monitoring limiting values. This requires precise analytical systems such as X-ray fluorescence, ICP- and atomic absorption spectrometers. These instruments are able to detect trace concentrations of hazardous compounds - for example cadmium, using an atomic absorption spectrometer in the flame atomization mode up to 0.1 mg/L, or using the di more

• Dimeric [small mu ]-oxo bridged molybdenum(VI) dioxo complexes as catalysts in the epoxidation of internal and terminal alkenes

  The preparation of the tridentate phenol based amine ligands HL1–HL4 is achieved via a convenient one-pot synthesis by reductive amination in quantitative yield in an autoclave under 7 bar H2 gas. Reaction of [MoO2(acac)2] and the corresponding ligand HLX (X = 1, 2 and 4) in methanol–H2O results in more

• Characterization of a pre-export enzyme-chaperone complex on the twin-arginine transport pathway

  The Tat (twin-arginine translocation) system is a protein targeting pathway utilized by prokaryotes and chloroplasts. Tat substrates are produced with distinctive N-terminal signal peptides and are translocated as fully folded proteins. In Escherichia coli, Tat-dependent proteins often contain redo more

• A Clock Reaction Based on Molybdenum Blue

  Clock reactions are rare kinetic phenomena, so far limited mostly to systems with ionic oxoacids and oxoanions in water. We report a new clock reaction in cyclohexanol that forms molybdenum blue from a noncharged, yellow molybdenum complex as precursor, in the presence of hydrogen peroxide. Interest more
