N2O Decomposition over Fe-ZSM-5: A Systematic Study in the Generation of Active Sites
Molecules, 2020 We have carried out a systematic investigation of the critical activation parameters (i.e., final temperature (673–1273 K), atmosphere (He vs. O2/He), and final isothermal hold (1 min–15 h) on the generation of “α-sites”, responsible for the direct N2O ...

Stacked Buck Converter: Current Ripple Elimination Effect and Transient Response
Energies, 2020 To balance the cost and volume when applying a low output current ripple, the power supply design should be able to eliminate the current ripple under any duty cycle in medium and high switching frequencies, and considerably reduce filter volume to ...

A Comparison of Double Convex and Double Concave Improved Nyquist Filters
Advances in Electrical and Computer Engineering, 2010 This paper presents a comparative analysis of two families of improved Nyquist filters with a piece-wise parabolic frequency characteristic. Their construction is based on a novel approach and produces ISI-free pulses that shows comparable or better ISI ...
