Membranes based on basic polymers and perfluorinated acids for hotter and drier fuel cell operating conditions
Autor: J. M. Larson, Steven J. Hamrock, William M. Lamanna, G. M. Haugen, A. Butenhoff Moss, Phuong Pham
Publikováno v: Journal of Power Sources. 172:108-114
Proton exchange membranes for fuel cells that operate under hotter and drier conditions are of interest for improved heat rejection and to reduce poisoning by carbon monoxide in reformed hydrocarbon fuels. Polybenzimidazole/phosphoric acid membranes

Response-specific sources of dual-task interference in human pre-motor cortex
Autor: M. M. Chun, J. M. Larson, René Marois, D. Shima
Publikováno v: Psychological Research. 70:436-447
It is difficult to perform two tasks at the same time. Such performance limitations are exemplified by the psychological refractory period (PRP): when participants make distinct motor responses to two stimuli presented in rapid succession, the respon

Thermal plasma synthesis of diamond
Autor: S. L. Grishick, J. M. Larson
Publikováno v: Pure and Applied Chemistry. 70:485-492
A numerical model was used to examine experimental data in which a gas chromatograph measured the composition of gas sampled through a 70-pn orifice in the growth substrate during atmospheric-pressure RF plasma diamond CVD. Substantial discrepancies

Wear and Wear Mechanism Simulation of Heavy-Duty Engine Intake Valve and Seat Inserts
Autor: S. Narasimhan, Yushu Wang, J. M. Larson, S. K. Schaefer
Publikováno v: Journal of Materials Engineering and Performance. 7:53-65
A silicon-chromium alloy frequently used for heavy-duty diesel engine intake valves was tested against eight different insert materials with a valve seat wear simulator. Wear resistance of these combinations was ranked. For each test, the valve seat

The effect of operating conditions on heavy duty engine valve seat wear
Autor: J. M. Larson, J. E. Larson, S. L. Narasimhan, Gary C. Barber, Yushu Wang
Publikováno v: Wear. 201:15-25
Engine valve seat wear affects engine performance. To improve valve quality and life is a common goal for both valve and engine manufacturers. By performing tests on a valve seat wear simulator, the effect of cycles, load and temperature on heavy dut
