Main factors affecting the long-term stability of microwave oscillator frequency are discussed in this paper. External factors affect the signal frequency at the output of any actual source, causing it to continuously change over time. Long-term frequency instability could be attributed to aging of the material. So, it is necessary to take special environmental factors into account, when designing microwave oscillators for space electronic equipment.

One Pot Synthesis

Direct “one-pot” synthesis is highly efficient to obtain performing mesoporous Ni–Al2O3catalysts able to resist deactivation by sintering and coke deposition during CH4reforming by CO2and H2O to produce “metgas”.
