  • Barely porous organic cages for hydrogen isotope separation

     · One method for improving the efficiency of separation of hydrogen from deuterium (D) is to exploit kinetic quantum sieving with nanoporous solids. This method requires ultrafine pore apertures (around 3 angstroms), which usually leads to low pore volumes and low D2 adsorption capacities. Liu et al. used organic synthesis to tune the pore size of the internal cavities of organic cage molecules.

  • Air/Oil Separator Why Direct Injection Makes Them A Must

     · Your factory system does a pretty good job at what it was designed to do, but it still may have a few problems. As air is being drawn through the system, oil that has been vaporized or atomized by high heat or rapidly moving parts, makes its way into the air. This air is then drawn through the system and into the intake manifold.
