Headline: Carbon capture method plucks CO2 straight from the air
■ Release Date: 2023.10.3
■ Published by: Northwestern University
■ Keywords: carbon dioxide, carbon capture, carbon sequestration
■ Abstract:
Even as the world slowly begins to decarbonize industrial processes, achieving lower concentrations of atmospheric carbon requires technologies that remove existing carbon dioxide from the atmosphere — rather than just prevent the creation of it.
Headline: Two-dimensional compounds can capture carbon from the air
■ Release Date: 2023.10.4
■ Published by: University of California - Riverside
■ Keywords: carbon dioxide, carbon capture, metal
■ Abstract:
Some of the thinnest materials known to humankind -- MXene and MBene compounds -- may provide solutions to scientists in their quest to curb the effects of global warming. These substances are only a few atoms thick, making them two-dimensional. Because of their large surface area, the materials have the potential to absorb carbon dioxide molecules from the atmosphere, which could help reduce the harmful effects of climate change by safely sequestering carbon dioxide, according to a review study.
Headline: Graphene oxide reduces the toxicity of Alzheimer's proteins
■ Release Date: 2023.10.4
■ Published by: Chalmers University of Technology
■ Keywords: carbon dioxide, carbon capture, carbon sequestration
■ Abstract:
A probable early driver of Alzheimer's disease is the accumulation of molecules called amyloid peptides. These cause cell death, and are commonly found in the brains of Alzheimer’s patients. Researchers have now shown that yeast cells that accumulate these misfolded amyloid peptides can recover after being treated with graphene oxide nanoflakes.
Headline: Volcanic ash effects on Earth systems
■ Release Date: 2023.10.4
■ Published by: Cornell University
■ Keywords: silicate, volcanic ash, minerals
■ Abstract:
To bridge the knowledge gap between volcanologists and atmospheric scientists working on climate change and observing global systems, researchers have characterized volcanic ash samples from many explosive eruptions of a broad compositional range.
Headline: Groundbreaking study shows defects spreading through diamond faster than the speed of sound
■ Release Date: 2023.10.5
■ Published by: DOE/SLAC National Accelerator Laboratory
■ Keywords: diamond, linear defects, metal
■ Abstract:
Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what give metals their strength and workability, but they can also make materials fail catastrophically – which is what happens every time you pop the pull tab on a can of soda. The fact that they can travel so fast gives scientists a new appreciation of the unusual types of damage they might do to a broad range of materials in extreme conditions.
Headline: Twisted science: New quantum ruler to explore exotic matter
■ Release Date: 2023.10.5
■ Published by: National Institute of Standards and Technology (NIST)
■ Keywords: graphene, electrical resistance, magnetic
■ Abstract:
Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard for electrical resistance that could calibrate electronic devices directly on the factory floor, eliminating the need to send them to an off-site standards laboratory.
Headline: Successful morphing of inorganic perovskites without damaging their functional properties
■ Release Date: 2023.10.5
■ Published by: City University of Hong Kong
■ Keywords: perovskites, semiconductors, energy
■ Abstract:
A research team has successfully morphed all-inorganic perovskites at room temperature without compromising their functional properties. Their findings demonstrate the potential of this class of semiconductors for manufacturing next-generation deformable electronics and energy systems in the future.
