Optical power evolution in fiber-optic networks: New framework for better modeling and control
With the emergence of internet services such as AI-generated content and virtual reality, the demand for global capacity has surged, significantly intensifying pressures on fiber-optic communication systems. To address this surge and reduce operation.....»»
Computer models suggest modern plate tectonics are due to blobs left behind by cosmic collision
A small team of geologists and seismologists at the California Institute of Technology has found evidence via computer modeling that suggest giant blobs of material near the Earth's core, believed to have been created by a cosmic collision 4.5 billio.....»»
Catalyst search shows how computing can take the guesswork out of chemistry
Imagine synthesizing and then testing over 50 different complex molecules to identify the most effective catalyst for a particular chemical reaction. The traditional approach to developing new catalysts for chemical reactions in this "try it and see".....»»
Smart labs for bespoke synthesis of nanomaterials are emerging
In the early 20th century, the development of a catalyst for ammonia synthesis by the Haber-Bosch method took more than 10,000 experiments before it was successful. The development of new materials is a time-consuming and costly process from design t.....»»
Computer models show heat waves in north Pacific may be due to China reducing aerosols
A team of oceanographers and planetary scientists at the Ocean University of China, working with a pair of colleagues from the U.S. and one in Germany, has found via computer modeling, that recent heat waves in the north Pacific may be due to a large.....»»
Team describes MXene-supported PtCo bimetallic catalyst for hydrogen evolution in acidic conditions
Hydrogen energy is considered a promising solution with high energy density and zero pollution emissions. Currently, hydrogen is mainly derived from fossil fuels, which increases energy consumption and greenhouse gas emissions, hindering efforts to a.....»»
A leap toward carbon neutrality: New catalyst converts carbon dioxide to methanol
Researchers at the University of Michigan have developed a catalyst material known as cobalt phthalocyanine that converts carbon dioxide—a significant driver of climate change—into renewable fuels such as methanol......»»
A global plastic treaty will only work if it caps production, modeling shows
An international agreement to end plastic pollution is due to be sealed this year in Busan, South Korea. At the penultimate round of negotiations, held in Ottawa, Canada, Rwanda and Peru proposed a target to cut the weight of primary plastics produce.....»»
New sugar-based catalyst could offer a potential solution for using captured carbon
A new catalyst made from an inexpensive, abundant metal and common table sugar has the power to destroy carbon dioxide (CO2) gas......»»
Precipitation may brighten Colorado River"s future, says modeling study
The Colorado River's future may be a little brighter than expected, according to a new modeling study from CIRES researchers. Warming temperatures, which deplete water in the river, have raised doubts the Colorado River could recover from a multi-dec.....»»
How the plant world shapes the climate cycle
In order to understand the Earth's resilience, researchers at ETH Zurich are modeling climate changes from times long past. And they show that plants are not simply victims of circumstances, but have helped to shape climate conditions on Earth......»»
