Synthesis, Structure And Redox Catalytic Properties Of Pt And Pd Ion Substituted Ce1-xMxO2(M= Ti, Zr & Hf) Oxygen Storage Capacity Nano-materials
(2010-09-28)
Three-way catalysis (TWC) involves simultaneous removal of the three pollutants (i.e., CO, NOx, and HCs) which led to the branch of auto-exhaust catalysis. CeO2 has become the main component of TWC catalyst because of its ...
Spectral Simplification In Scalar And Dipolar Coupled Spins Using Multiple Quantum NMR : Developments Of Novel Methodologies
(2010-07-28)
Spin selective MQ-SQ correlation has been demonstrated by either selective pulses in homo-nuclear spin systems in isotropic and weakly orienting chiral media or by nonselective pulses in hetero-nuclear spin systems in ...
