New evaluation framework helps quantify supply and demand of carbon sequestration services
The Lancang Mekong River Basin (LMRB) connects six countries in Southeast Asia. To support the ecological, economic and social sustainable development of the LMRB, low carbon management services need to be implemented in each country within the basin.....»»
Some Chinese cities have outsourced on others" efforts to cut carbon emissions
Experts have identified 240 Chinese cities whose emission reductions are mainly benefiting from the carbon mitigation actions of other cities, while the initial cities are putting in less effort themselves......»»
Simple new process stores carbon dioxide in concrete without compromising strength
By using a carbonated—rather than a still—water-based solution during the concrete manufacturing process, a Northwestern University-led team of engineers has discovered a new way to store carbon dioxide (CO2) in the ubiquitous construction materi.....»»

Permeable and robust polymer-silica hybrid armor on cell catalyst for sustainable biomanufacturing
Whole-cell catalysis is one of the several central techniques in green biomanufacturing, which can be categorized into living cell catalysis, resting cell catalysis, and inactivated cell catalysis. Among these, inactivated cell catalysis features the.....»»
Underwater mountains and their impact on ocean circulation
Colossal undersea mountains, towering up to thousands of meters high, stir up deep sea currents: impacting how our ocean stores heat and carbon......»»
New insights into mechanical weakness of twisted carbon nanotube yarns
Aside from being an essential building block for life, carbon is being actively researched due to its versatility as an engineering material. Carbon nanotubes (CNTs), in particular, have demonstrated tremendous potential for aerospace, semiconductor,.....»»
Climate inaction undermines public support for lifestyle changes, study finds
New research into the public perception of climate change initiatives finds that while there is strong support for low-carbon lifestyles, inaction is limiting public beliefs that a low-carbon future is possible......»»
Shaping the future of polymer nanocarriers
Scientists have taken a significant step towards the development of tailor-made chiral nanocarriers with controllable release properties. These nanocarriers, inspired by nature's helical molecules like DNA and proteins, hold immense potential for tar.....»»
Researchers develop polymer fibers that can facilitate controlled, local drug delivery
Medical products such as ointments or syringes reach their limits when it comes to delivering medication locally—and above all in a controlled manner over a longer period of time. Empa researchers are therefore developing polymer fibers that can de.....»»
Sediments reveal the ancient ocean during a mass extinction event
About 183 million years ago, volcanic activity in modern South Africa unleashed an estimated 20,500 gigatons of carbon dioxide (CO2) into the ocean–atmosphere system over a period of 300 to 500 thousand years. Known as the Toarcian Oceanic Anoxic E.....»»
Study explores high-performance copper/graphene composite conductor for motors
A study, led by Tingting Zuo, was based on the idea of in-situ growth, and a series of Cu/Gr composites with improved interfaces were prepared by vacuum hot press sintering. Combined with cold-drawing and heat-treatment processes, composite wires wit.....»»
Scientists explore the vast reservoir of dissolved organic matter in oceans
