Modeling a better catalyst for PIBSAs
Polyisobutenyl succinic anhydrides (PIBSAs) are important for the auto industry because of their wide use in lubricant and fuel formulations. Their synthesis, however, requires high temperatures and, therefore, higher cost......»»
Multi-heterointerfaces for selective and efficient urea production
A major impediment to industrial urea synthesis is the lack of catalysts with high selectivity and activity. Prof. Yuliang Li (Institute of Chemistry, Chinese Academy of Sciences) and coworkers reported a new catalyst system suitable for the highly s.....»»
Early forests did not significantly change the atmospheric CO2, finds paleoclimate modeling study
Scientists have discovered that the atmosphere contained far less CO2 than previously thought when forests emerged on our planet, the new study has important implications for understanding how land plants affect the climate......»»
New method helps reduce uncertainty in numerical models
The uncertainty related to physical parameters is a major challenge in numerical modeling. However, due to the large number of such parameters in numerical models, reducing the uncertainty for all of them would be extremely expensive in terms of manp.....»»
Model shows extinction cascades caused by land use and climate change will wipe out more than 25% of world biodiversity
A new tool developed by European and Australian scientists enabling unparalleled modeling of interconnected species loss shows cascading extinctions are unavoidable, and that the Earth will lose some 10% of its animals and plants by 2050, rising to 2.....»»

Music always makes life a whole lot more bearable, and it can prove to be the catalyst during moments when our lives are challenging and difficult. However, with so many different ways and avenues for us to enjoy our music, going wireless happens to.....»»
Coupled computer modeling can help more accurately predict coastal flooding, study demonstrates
When Hurricane Florence hit the coast of North Carolina as a Category 1 storm in 2018, it set new records for rainfall, creating damaging 500-year flooding events along the Cape Fear River Basin......»»
Why synonymous mutations are not always silent
New modeling shows how synonymous mutations—those that change the DNA sequence of a gene but not the sequence of the encoded protein—can still impact protein production and function. A team of researchers led by Penn State chemists modeled how ge.....»»
High-resolution modeling of aviation emissions reveals which airline routes in Norway pollute the most
Norwegian greenhouse gas emissions from air traffic are more than twice as high as the worldwide average......»»
Atmospheric transport modeling study: When the Aral Sea dried up, Central Asia became dustier
Winds kick up large amounts of dust from the desert that has formed as the world's fourth largest lake has disappeared, spreading it around the region and raising concerns about public health......»»
