Sunlight Converts CO2 and Methane into Valuable Chemicals

Scientists use a blueprint of photosynthesis to produce greener, renewable productsMcGill University Drawing inspiration from natural photosynthesis, scientists have developed a technique that uses sunlight to convert two major greenhouse gases into valuable chemicals for fuel and industrial applications. Researchers from McGill University have created a novel process called photo-driven oxygen-atom-grafting. This method employs gold,...

Chemical Discovery on Mars Suggests Origins of Life on Earth

Credit: Pixabay Just over ten years ago, a robotic rover on Mars provided a long-awaited answer to a critical question: it confirmed the presence of organic material buried in the sediment of the planet's ancient lakebeds. Since then, we have continued to discover organic molecules on Mars, distributed in a manner indicating widespread carbon chemistry on...

New Method Cuts Costs by 30% in Converting CO2 to High-Value Chemicals

NUS researchers, led by Assistant Professor Lum Yanwei, have developed a groundbreaking technique to address rising CO2 emissions and their impact on climate change. Their method greatly improves the conversion of waste CO2 into valuable chemicals and fuels, directly from treated industrial flue gas. This innovation turns CO2 into key raw materials like ethylene...

Heat And Bacteria Recycle Blended Plastics Into Useful Chemicals

Mixed plastics are difficult to recycle, but a new process shows how it can be done.Credit: China Photos/Getty Mixtures of plastics, normally a headache to recycle, have been broken down into helpful, smaller chemical ingredients in one two-step process, reported in Science on 13th October. The plastics problem facing the globe is exacerbated by the difficulty...

Investigators from the United States Navy Discuss “Whether Cold Fusion or Low-Energy Nuclear Reactions”

After more than three decades of simmering debate in specialized physics groups and cutting-edge research communities, the debate over cold fusion (also known as low-energy nuclear reactions or LENRs) refuses to die. From another present, ardent supporters have lacked the consistent, reproducible findings and theoretical basis that general acceptance requires. On the other hand,...
