  • High performance CNT catalyst relating to its electroconductivity
    on January 16, 2018 at 2:56 pm

    Biofuels were obtained from Jatropha Oil using carbon nanotube (CNT) catalyst, which showed efficient cracking activity. The performance was activated by the high stability, metal sites, acid sites, electroconductivity, and coking tolerance of CNT. Two cracking circulations were found in the hydroprocessing. Meanwhile, the sulphur-free process was eco-friendly. […]

  • One of planet's largest volcanic eruptions
    on October 11, 2017 at 1:11 pm

    Researchers have determined that the Pacific Northwest was home to one of the Earth's largest known volcanic eruptions, a millennia-long spewing of sulfuric gas that blocked out the sun and cooled the planet. Only two other eruptions -- the basalt floods of the Siberian Traps and the Deccan Traps -- were larger, and they led to two of the Earth's great extinctions. […]

  • Biochar shows benefits as manure lagoon cover
    on August 9, 2017 at 6:02 pm

    Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. New methods may reduce these negatives while potentially adding some positives: biochar covers. […]

  • Biochar could clear the air in more ways than one
    on July 27, 2017 at 2:29 pm
