20100048380 | Novel catalyst for oxygen reduction reaction in fuel cells - A method for making a carbon-metal-nitrogen oxygen reducing cathode catalyst, the method comprising mixing a carbon source with a transitional metal precursor to form a metal precursor loaded carbon substrate; adding a nitrogen precursor compound to the metal precursor loaded carbon substrate to form a carbon-metal-nitrogen precursor; and pyrolyzing the carbon-metal-nitrogen precursor in a closed vessel, thereby forming an oxygen reducing cathode catalyst. The carbon-metal-nitrogen catalyst requires no precious metal such as Pt, and also provides benefits such as controlled deposition of catalytically active nitrogenous compounds that can increase the catalytic activity of the catalyst when compared to gaseous deposition of nitrogen to the surface of the carbon support. | 02-25-2010 |

20140287399 | SYSTEMS AND METHODS FOR LEARNING AND LEARNING ORIENTED ASSESSMENT - The technique relates to a system and method for learning and learning oriented assessment of at least one learner based on a role to be performed by the at least one learner. This technique involves identifying knowledge areas related to a particular role to be performed by the learner. Under each knowledge area different learning workflows are identified and relevant topics are mapped to the learning workflows. The performance expectation from the learner at each learning workflow level is defined. The one more challenges related to the mapped topics are created and presented to the learner to solve and a score is generated for solving the challenges. This score is compared with the predefined performance expectation to determine the learning effectiveness of the learner and a capability index is computed for the learner. | 09-25-2014 |
