Article Synopsis
  • Zeolite molecular sieves are crucial for applications in gas separation and catalysis, needing precise pore sizes as small as 0.1 Å for effective performance.
  • By covalently adding a variety of organic functional groups to the zeolite's pore walls, researchers can adjust the effective pore diameters, which enhances their selective adsorption capabilities.
  • Experiments show that functionalized zeolites, like 4-Methoxybenzene-functionalized MOR, can significantly improve the separation of gases, achieving high selectivity ratios for separating light olefins from paraffins.

In this paper, the densification mechanism of ultrasonic compaction was analyzed using a force balance model. Ultrasonic compaction is quite a promising way to solve the lower mechanical property problem of green compact in the compaction process, although it has some obstacles to overcome for its various applications. Our model proposes that the resultant density is achieved as the applied and resistance forces reach the equilibrium state.
