周明顺团队研究发现，球团还原膨胀率随SiO2含量增加而降低，随碱度变化呈开口向下的抛物线关系。针对鞍钢铁精矿特性，该团队成功避开了碱度为0.5～0.6的不利区间。基于此理论指导，鞍钢开发的碱性球团矿实现了品质跃升：全铁含量稳定在64%以上，FeO含量 ...

While we’ve made major strides in generating renewable energy, storing that green power to use when the Sun isn’t shining or the wind isn’t blowing remains a major engineering challenge. Now, as IEEE ...

Natural biological systems cannot efficiently convert waste CO₂ or its derivatives into useful building-block chemicals at a scale that can keep pace with rising atmospheric carbon. Engineer a fully ...

Researchers found that eroded lava rubble beneath the South Atlantic can trap enormous amounts of CO2 for tens of millions of years. These porous breccia deposits store far more carbon than previously ...

China has launched the world’s first carbon dioxide–based power generator, using supercritical CO2 instead of steam to produce electricity with over 50% efficiency. The system harnesses industrial ...

The 2025 Global Carbon Budget projects 38.1 billion tons of fossil carbon dioxide (CO2) emissions this year. This is a 1.1% rise for 2025, reaching an all-time record high. Decarbonization of energy ...

A new copper-magnesium-iron catalyst transforms CO2 into CO at low temperatures with record-breaking efficiency and stability. The discovery paves the way for affordable, scalable production of carbon ...

GENEVA (AP) — Heat-trapping carbon dioxide levels in the atmosphere jumped by the highest amount on record last year, soaring to a level not seen in human civilization and "turbo-charging" the Earth's ...

Atmospheric carbon dioxide levels jumped by a record amount in 2024 to push concentrations to their highest point since measurements began, the UN’s World Meteorological Organization (WMO) has ...

On September 2, 2023, a specially equipped aircraft flew to Colstrip, Montana. On this fine late summer morning, the plane flew over the Colstrip coal-fired power plant, one of the largest and ...

The award-winning science writer Peter Brannen makes the case for an often vilified compound in “The Story of CO2 Is the Story of Everything.” By Jaime Green Jaime Green is the author of “The ...
