Researchers have developed a reactor that pulls carbon dioxide directly from the air and converts it into sustainable fuel, using sunlight as the power source.

The researchers, from the University of Cambridge, say their solar-powered reactor could be used to make fuel to power cars and planes, or the many chemical and pharmaceutical products we rely on. It could also be used to generate fuel in remote or off-grid locations.

Unlike most carbon capture technologies, the reactor developed by the Cambridge researchers does not require fossil-fuel-based power, or the transport and storage of car...

Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel’s potential energy while the rest is lost as heat through exhaust.

Now, a study published in ACS Applied Materials & Interfaces demonstrates how to convert exhaust heat into electricity...

Various clean energy technologies have been developed to meet the rapidly intensifying energy demand and dwindling fossil fuel reserves. However, many of these technologies are hindered by low efficiency and high costs.

Hydrovoltaic (HV) mechanisms, in which electricity is generated by the direct interaction of nanostructured materials and water molecules, have recently emerged as promising, cost-efficient alternatives. HV systems show particular promise for powering electrical sensors, including fire sensors.

Traditional fire sensors rely on batteries to operate during power outages, but these batteries can explode during fires...

Xenon gas inhalation reduced neurodegeneration and boosted protection in preclinical models of Alzheimer’s disease. Most treatments being pursued today to protect against Alzheimer’s disease focus on amyloid plaques and tau tangles that accumulate in the brain, but new research from Mass General Brigham and Washington University School of Medicine in St. Louis points to a novel — and noble — approach: using Xenon gas...
