Solid Adsorbents for CO2 Capture and Utilization

Recently, Indian scientists have discovered a novel strategy to synthesize novel solid adsorbents for CO2 capture and utilization.


  • Carbon capture and utilization are growing fields of research focusing on reducing CO2 emissions. Despite several industrial advancements having been already demonstrated, none of the technologies can provide an economically viable and complete CO2 capture and utilization solution. Therefore, fundamental research on novel solid adsorbents might offer a critical material for CO2 capture and utilization.

  • The system is a next generation missile-based standoff torpedo delivery system.

Nobel Prize in Chemistry 2021

Benjamin List (Germany) and David W.C. MacMillan (USA) were announced joint winners of Nobel Prize in Chemistry 2021 “for the development of asymmetric organocatalysis”.


  • The type of catalysis developed independently by Benjamin List and David MacMillan, called organocatalysis, uses small organic molecules that are generally both environmentally friendly and inexpensive to produce. The use of organocatalysts has rapidly expanded since 2000. This is largely due to their ability to drive asymmetric synthesis.
