A domestic electron ion collider would unlock scientific mysteries of atomic nuclei

The science questions that could be answered by an electron ion collider (EIC) -- a very large-scale particle accelerator -- are significant to advancing our understanding of the atomic nuclei that make up all visible matter in the universe, says a new report.

Quality of the concrete plays an important role in the construction field as the concrete is the excessive element in any construction. The strength...

New application of blue light sees through fire

Researchers have demonstrated that ordinary blue light can be used to significantly improve the ability to see objects engulfed by large, non-smoky natural gas fires -- like those used in laboratory fire studies and fire-resistance standards testing.

Determine Effect of Trench Excavation on Nearby Buildings by Rule of Thumb

Image
Clearly, trench excavation affects nearby buildings and causing them to settle. The major factors that cause building settlement are soil relaxation...

Detecting damage in non-magnetic steel with the help of magnetism

Magnetic test methods are used to detect damages to materials, which was previously impossible with non-magnetic steel. Researchers have now developed a process in which they apply a thin magnetic layer to steel. Changes in the microstructure can thus be detected by changes in magnetic effects. Materials such as aluminum can also be tested in this way.

Cold wave reveals potential benefits of urban heat islands

Researchers have found that the urban heat island effect -- cities are hotter in the summer than their surrounding areas -- also helps keep cities warmer during extreme cold. The findings have implications for urban planners in areas such as New York City or Chicago, which experience marked seasonal temperature swings.

Eagle-eyed machine learning algorithm outdoes human experts

Researchers have trained computers to quickly and consistently detect and analyze microscopic radiation damage to materials under consideration for nuclear reactors. And the computers bested humans in this arduous task.

A social tool for evaluating the environmental impact of residential buildings

for the first time, an open-source computing tool can, simply and intuitively, calculate the CO2 emissions in each phase of a building project, in order to obtain a global picture of its carbon footprint from its conception and to help decide every variable in the construction process.

Biological signalling processes in intelligent materials

AI technology could help protect water supplies

Progress on new artificial intelligence (AI) technology could make monitoring at water treatment plants cheaper and easier and help safeguard public health.

Close-ups of grain boundaries reveal how sulfur impurities make nickel brittle

Engineers have shed new light on a scientific mystery regarding the atomic-level mechanism of the sulfur embrittlement of nickel, a classic problem that has puzzled the scientific community for nearly a century. The discovery also enriches fundamental understanding of general grain boundaries that often control the mechanical and physical properties of polycrystalline materials.

Electronic stickers to streamline large-scale 'internet of things'

Researchers have developed a new fabrication method that makes tiny, thin-film electronic circuits peelable from a surface. The technique not only eliminates several manufacturing steps and the associated costs, but also allows any object to sense its environment or be controlled through the application of a high-tech sticker.

How gold nanoparticles could improve solar energy storage

Star-shaped gold nanoparticles, coated with a semiconductor, can produce hydrogen from water over four times more efficiently than other methods - opening the door to improved storage of solar energy and other advances that could boost renewable energy use and combat climate change, according to researchers.
