30/7/2012· High activity and predominant shape selectivity was observed on ZSM-5 , , , , and the reaction is effective above 450 C. The high p-selectivity of modified ZSM5 has been attributed to the restricted diffusion inside the channels, i.e., the p-xylene, which rapidly
Review on High Gain Conical Horn Antenna for Short-Range Communiions Abstract: Horn antennas are very popular at UHF (300 MHz-3 GHz) and higher frequencies ( as high as 140 GHz). Horn antennas often have a directional radiation pattern with a high antenna gain, which can range up to 25 dB in some cases, with 10-20 dB being typical.

The hybrid silicon carbide power modules are available from 50A to 600A in 1200V in sixpack, half-bridge and chopper topologies. SiC Schottky freewheeling diodes have virtually no switching losses and reduce the turn-on losses of the IGBT drastically. In coination with standard or high-speed IGBTs, higher switching frequencies can be achieved
