Chemistry:Cleaning up catalystsCatalytic converters in car exhausts reduce harmful emissions but have a limited life. A palladium-containing material that responds to the changing atmosphere in a car's exhaust could be the basis of a more effective and long-lasting converter.Magdalena Helmer...

catalytic chemistry, photosynthetic energy transduction, and quantum information science. Xinping Wang and coworkers demonstrate that Lewis acid coupled electron transfer is an efficient way to prepare stable RIPs. Understanding the structure and photoelectric proces...
Although at times tempted to excessive speculation in view of the rapid developments in the sciences of his time (relativity theory, photochemistry, catalytic reaction mechanisms), Bachelard has perhaps the strongest claim to be first philosopher of chemistry. His views can be summed up in one cita...
This page describes the Chemistry Academic Word List (CAWL), giving information on what the CAWL is, details about how it was developed, information on text coverage of the CAWL, mentions some problems with the published list, as well as giving a complete list of words in the CAWL. To exp...
Rate of reaction topic is not only mathematical, but very contextual material, so that many applications of the concept of rate of reaction can be found in life such as corrosion of ship hulls, decomposition of ozone by chlorofluorocarbons, use of a catalytic converter to reduce pollutants ...
The equilibrated dynamic combinatorial library contains, amongst various macrocycles, two different types of [2]catenanes that are non-isomeric. The formation of these [2]catenanes is due to a spontaneous stereo and structurally divergent assembly of the building blocks....
Th is means that in countries 8 Cambridge IGCSE Chemistry shop: the neverland S exhaust gases: unburnt fuel, carbon monoxide and nitrogen oxides, with carbon dioxide, water and nitrogen exhaust gases: carbon dioxide, water and nitrogen catalytic converter Figure 1.10 A catalytic converter changes ...
a general synthetic approach for organic lateral heterostructures with tunable structural and optical properties. Utilizing the structural similarity of cocrystals, they successfully synthesized organic solid solution microwires and lateral heterostructure microwires. Furthermore, a multichannel signal converter ...
Precaution: catalytic converter Catalyst: Pt, Rh, Pd Principles - Oxidation of carbon monoxide:2CO+2NO→2CO2+N2 - Oxidation of unburnt hydrocarbons:CxHy+(x+y4)O2→xCO2+y2H2O - Reduction of nitrogen oxides:4CO+2NO2→4CO2+N2,2CO+2NO→2CO2+N2 ...
