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......»»
BESSY II: Surface analysis of catalyst particles in aqueous solutions
Green hydrogen can be produced directly in a photoelectrochemical cell, splitting water with solar energy. However, this requires the development of super-efficient photoelectrodes that need to combine many talents at the same time: They must be exce.....»»
Team develops highly active catalyst for alkaline water electrolysis using boron and sulfur
Development of hydrogen-related technologies is essential to realize and sustain a carbon-neutral society. Hydrogen is obtained from water electrolysis; however, the existing catalysts are made of rare and expensive metals. A research group led by th.....»»
Chemists recycle shrimp waste as catalyst for hydrogen generation
Flexible spheres of the biomolecule chitosan, made from shrimp waste, can be used for catalysts that generate hydrogen gas from borohydride salts. In a paper in Green Chemistry, a research team at the University of Amsterdam (UvA) shows how the spher.....»»
Machine learning enables accurate electronic structure calculations at large scales for material modeling
The arrangement of electrons in matter, known as the electronic structure, plays a crucial role in fundamental but also applied research, such as drug design and energy storage. However, the lack of a simulation technique that offers both high fideli.....»»

New study evaluates uncertainties in modeling El Niño-related changes in atmospheric circulation
A research team from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences has examined the performance of eight prominent reanalysis datasets in capturing regional Hadley Circulation (HC) responses to El Niño–Southern Osci.....»»
Bees Are Astonishingly Good at Making Decisions
Computer modeling explains a key facet of bees’ decision-making skills—something only seen previously in humans and other primates.....»»
56 million-year-old Eocene global warming may indicate a wetter future
Modeling of Earth's response to global warming has suggested dry regions will become more arid and wet regions will experience more precipitation, with an uneven distribution of moisture in the atmosphere. With enhanced seasonality, there will likely.....»»
Animation shows what the world would look like if you could see carbon dioxide emissions
It's a strange, eerie-looking place. Carbon dioxide gas appears… and disappears in cycles and bursts throughout the year. It's how our planet would look if we could detect carbon dioxide (CO2) with our eyes. Scientists at NASA's Global Modeling and.....»»
Remote lake emissions from the Tibetan Plateau challenge global climate modeling
Earth's complex systems interact between atmospheric, terrestrial, hydrological, cryological (ice and snow) and biological processes in feedback loops. Understanding their relationships is important for modeling their future impacts, particularly reg.....»»
How hardening Microsoft 365 tenants mitigates potential cloud attacks
Moving critical data and workloads to the cloud has significantly changed information security teams. But most don’t have the resources to be successful in their cloud attack modeling—not to mention the deployment of measurable controls to defend.....»»
New nationwide modeling points to widespread racial disparities in urban heat stress
From densely built urban cores to sprawling suburbia, cities are complex. This complexity can lead to temperature hot spots within cities, with some neighborhoods (and their residents) facing more heat than others......»»
Better climate modeling and data can help Baltimore weather a hotter, stormier future
If you were to stand at the intersection of Maryland Avenue and West 24th Street in Baltimore's Old Goucher neighborhood and travel back in time 10 years, you would probably be shocked at the transformation. Back then, pavement blanketed the neighbor.....»»
Computational advance can help researchers model climate with higher fidelity
Increased computational power has dramatically improved climate modeling over the past several years, allowing scientists to better forecast long term climate evolution. Despite the computers becoming faster and more efficient, cloud modeling was sti.....»»
Black Kite releases two modeling solutions for ransomware and business interruption scenarios
Black Kite released automated cyber risk quantification (CRQ) modeling for ransomware and business interruption scenarios. The new capabilities, which automates FAIR methodology, extends Black Kite’s data breach CRQ model to now provide visibility.....»»
Predicting and planning for forest fires requires modeling of many complex, interrelated factors, says researcher
Global warming is here. As anticipated for more than 50 years now, the temperature and levels of atmospheric CO2 have increased......»»
New report underscores importance of microbes in climate change modeling
The American Academy of Microbiology, an honorific leadership group and scientific think tank within the American Society for Microbiology (ASM), has released a new colloquium report, "Microbes in Models: Steps for Integrating Microbes into Earth Sys.....»»
Shared modeling can help schools predict, avert dropouts
A research team co-led by Cornell found that for schools without the resources to conduct learning analytics to help students succeed, modeling based on data from other institutions can work as well as local modeling, without sacrificing fairness......»»
Modeling study: Linking carbon markets with an allowance exchange rate yields environmental, economic dividends
Carbon markets have become a critical policy tool to combat climate change. They allow firms that emit greenhouse gases to buy and sell the right to pollute, which gives the firms flexibility while also reducing carbon emissions at the lowest cost. A.....»»
A breakthrough in the electrooxidation of propylene
