HC Plastics News: ExxonMobil and ITQ scientists have discovered a new material that is formed from a unique structure of silicalite that can be used in gas separation technology. As microporous materials, zeolites are commonly used for catalysis and adsorption in chemical processes. The use of ITQ-55 zeolite enables separation at ambient temperature with high selectivity. The results of the analysis can also be used to develop new materials that can be used as membranes or adsorbents in different gas separation applications in the manufacture of chemical products.
The new ITQ-55 material has the potential to selectively separate ethylene from ethane due to its unique flexibility and porous structure. The new material consists of a flexible large channel-connected heart-shaped unit that allows only flat ethylene molecules to pass through and circular ethane molecules to be blocked. Therefore, innovative materials function like a flexible molecular sieve.
It is reported that this material is a new potential and innovative material that can greatly reduce energy consumption and emissions in ethylene synthesis. The combination of this innovative material with other separation processes can reduce the energy required to separate ethylene by nearly 25% at current levels and reduce associated CO2 emissions.

Diamond hand polishing and grinding pads manufactured using diamond flexible material for use on edges, corners and flat surfaces of a wide range of materials such as granite, marble, engineered stones, glass, ceramics, composites and hard metals. are used for polishing, grinding, restoring/cleaning areas hard to reach by polishing tools like wet grinder polisher, angle grinder etc. A useful and handy diamond tool to polish corners, contoured surface like sink, join of two bullnose surface for Granite polishing, Concrete polishing, Marble polishing, Terrazzo polishing, Travertine polishing, glass polishing and their restoration etc. These diamond tools may be used for floor polishing, counter top polishing, stone sculpture polishing etc. It could be useful and cost saver for small polishing project. Hand polishing could be time consuming over polishing using tools like grinders etc.
