Optical effects of the divalent functionalization of carbon nanotubes
Scientists have learned how to place crystalline defects in new materials with atomic-scale precision. This enables materials that can control excitons—energy carriers that are similar to subatomic particles. New research shows that, by precisely a.....»»
Ytterbium thin-disk lasers pave the way for sensitive detection of atmospheric pollutants
Alongside carbon dioxide, methane is a key driver of global warming. To detect and monitor the climate pollutants in the atmosphere precisely, scientists at the Max Planck Institute for the Science of Light (MPL) have developed an advanced laser tech.....»»
Metalenses harness AI for high-resolution, full-color imaging for compact optical systems
Modern imaging systems, such as those used in smartphones, virtual reality (VR), and augmented reality (AR) devices, are constantly evolving to become more compact, efficient, and high-performing. Traditional optical systems rely on bulky glass lense.....»»
Mechanical metamaterial enables long-distance component interaction for unique stretching properties
Metamaterials are artificial materials that do not occur in nature. Their components function like atoms in conventional materials but have special optical, electrical and magnetic properties. Interaction between the components is crucial to a metama.....»»
Telescope for NASA"s Roman mission complete, delivered to Goddard
NASA's Nancy Grace Roman Space Telescope is one giant step closer to unlocking the mysteries of the universe. The mission has now received its final major delivery: the Optical Telescope Assembly, which includes a 7.9-foot (2.4-meter) primary mirror,.....»»
Study finds four global policies could eliminate >90% of plastic waste and 30% of linked carbon emissions by 2050
A study released in Science determines that just four policies can reduce mismanaged plastic waste—plastic that isn't recycled or properly disposed of and ends up as pollution—by 91% and plastic-related greenhouse gases by one-third......»»
Researchers say impact of Trump"s climate policies "recoverable"
US president-elect Donald Trump's expected climate rollbacks will likely have a "small" impact on global warming, as long as other countries resist the temptation to slacken their own carbon-cutting efforts, new research found Thursday......»»
Agrivoltaics for sustainable food, energy and water management in East Africa
Combining solar power production with agriculture can significantly boost crop yields, conserve water and generate low-carbon electricity for areas particularly vulnerable to climate change, a new study has shown......»»
Scientists develop a phase-transformable membrane for efficient gas separation
Industrial gas separation, essential for clean energy and environmental protection, demands efficiency and adaptability. Current materials, however, lack the flexibility to selectively separate gases like carbon dioxide (CO2) and hydrogen (H2) while.....»»
Stark warning on emissions as leaders split on climate goals at COP29
Global leaders offered competing views on how to tackle climate change at UN-led talks Wednesday as a new report warned the world must reach carbon neutrality much sooner than planned......»»
Nations to submit boosted climate plans: what"s at stake?
Nations have begun setting carbon-cutting targets for the decade ahead, and how ambitious these pledges are could make or break global efforts to avoid dangerous levels of climate change......»»
Microplastics Could Be Making the Weather Worse
Microplastics cause clouds to form in places where they wouldn't otherwise, which is likely to have knock-on effects on the weather and climate......»»
Nations approve new UN rules on carbon markets at COP29
Governments at the COP29 talks approved Monday new UN standards for international carbon markets in a key step toward allowing countries to trade credits to meet their climate targets......»»
Study reveals why carbon boosts metal nanoparticle catalysts
Precious metals play an important role in the chemical industry as catalysts: With the help of silver, platinum, palladium or other elements, chemical reactions can take place that would otherwise not progress or would only progress at a much lower r.....»»
Private jet carbon emissions soar 46%: Study
The carbon footprint from private jet travel grew 46 percent between 2019 and 2023 and will keep rising unless the ultra-luxury industry is regulated, according to new research published Thursday......»»
Transforming polyethylene: From functionalization to antibacterial properties for sustainable applications
Polyethylene (PE) is one of the most widely used and versatile plastic materials globally, prized for its cost-effectiveness, lightweight properties and ease of formability. These characteristics make PE indispensable across a broad spectrum of appli.....»»
China passes energy law to "promote carbon neutrality"
China on Friday passed a new energy law to promote carbon neutrality, state media reported, as Beijing moves ahead with its pledge to decarbonize its economy by 2060......»»
Plastics pollution worsens the impacts of all planetary boundaries, new study says
Plastics are not as safe and inert as previously thought. A new research study written by an international team of researchers uses the planetary boundaries framework to structure the rapidly mounting evidence of the effects of plastics on the enviro.....»»
Advances in plate tectonics research provide a new view of deep Earth"s carbon emissions
From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from.....»»
Battling air pollution may contribute to climate change by impacting soil carbon storage
Decades-old policies aimed at improving air quality may also be accelerating global climate change, warns a recent study published in the journal Ecology......»»
Calcite: The versatile mineral shaping the future of carbon removal
Found all over the world, calcite is the most stable form of calcium carbonate and is the main mineral found in limestone......»»
