New method can pinpoint cracks in metal long before they cause catastrophes — ScienceDaily

When metallic components in airplanes, bridges and other structures crack, the results are often catastrophic. But Johns Hopkins University researchers have found a way to reliably predict the vulnerabilities earlier than current tests.

In a paper published today in Science, Johns Hopkins University researchers detail a new method for testing metals at a microscopic scale that allows them to rapidly inflict repetitive loads on materials while recording how ensuing damage evolves into cracks.

“We’re able now to have a more fundamental understanding about what leads up to cracks,” El-Awady said. “The practical implication is that it will allow us to understand and predict when or how the material is going to fail.”

Whether it is the pounding of vehicles on bridges or shifts in air pressure on airplanes, such continuous change called “cyclic loading” gradually induces slips in the internal molecular structure of the most durable metals until cracks

Finding vaporized metal in the air of an exoplanet

WASP-121b is an exoplanet located 850 light years from Earth, orbiting its star in less than two days—a process that takes Earth a year to complete. WASP-121b is very close to its star—about 40 times closer than Earth to the Sun. This close proximity is also the main reason for its immensely high temperature of around 2,500 to 3,000 degrees Celsius. This makes it an ideal object of study to learn more about ultra-hot worlds.


Researchers led by Jens Hoeijmakers, first author of the study and postdoctoral research fellow at the National Centre of Competence in Research PlanetS at the Universities of Bern and Geneva, examined data that had been collected by the high-resolution HARPS spectrograph. They were able to show that a

PlayStation 5 uses liquid metal — here’s why that’s cool

PlayStation 5 is going to ship to consumers with liquid metal between its AMD system-on-a-chip and its heatsink. This is something that was unthinkable in previous consoles for a number of reasons. But Sony engineers have tackled the challenges, and this could enable the PS5 to expel heat much faster than its predecessors.

Heat management is a huge part of engineering any electronics system. And Sony obviously emphasized the importance of cooling during the PS5’s design phase. This might result in the PS5 running cooler and quieter. But more important, it should enable the system to run demanding games without crashing.

Let’s break down what this all means first.

PlayStation 5’s liquid metal is necessary due to extreme temperatures

Processors generate heat. That is an inevitable byproduct of the way they work. And modern CPUs and GPUs can produce a lot of heat without sacrificing stability and performance. But if

Nano-scientists develop a molecular tool to change the structure of a metal surface — ScienceDaily

The surface of metals plays a key role in many technologically relevant areas, such as catalysis, sensor technology and battery research. For example, the large-scale production of many chemical compounds takes place on metal surfaces, whose atomic structure determines if and how molecules react with one another. At the same time, the surface structure of a metal influences its electronic properties. This is particularly important for the efficiency of electronic components in batteries. Researchers worldwide are therefore working intensively on developing new kinds of methods to tailor the structure of metal surfaces at the atomic level.

A team of researchers at the University of Münster, consisting of physicists and chemists and led by Dr. Saeed Amirjalayer, has now developed a molecular tool which makes it possible, at the atomic level, to change the structure of a metal surface. Using computer simulations, it was possible to predict that the restructuring of

Astronomers turn up the heavy metal to shed light on star formation

Astronomers from The University of Western Australia’s node of the International Center for Radio Astronomy Research (ICRAR) have developed a new way to study star formation in galaxies from the dawn of time to today.


“Stars can be thought of as enormous nuclear-powered processing plants,” said lead researcher Dr. Sabine Bellstedt, from ICRAR.

“They take lighter elements like hydrogen and helium, and, over billions of years, produce the heavier elements of the periodic table that we find scattered throughout the universe today. The carbon, calcium and iron in your body, the oxygen in the air you breathe, and the silicon in your computer all exist because a star created these heavier elements and left them behind,” Bellstedt said. “Stars are the ultimate element factories in the universe.”

Understanding how galaxies formed stars billions of years ago requires the

The key to lowering CO2 emissions is made of metal — ScienceDaily

Carbon dioxide (CO2) levels are rising and our planet is heating up. What do we do? What if we used this excess CO2 as a raw material to produce things we need — similar to how plants use it to produce oxygen.

This is one thing artificial photosynthesis has set out to do.

Artificial photosynthesis is a chemical process that mimics the natural process of photosynthesis to convert sunlight, water, and carbon dioxide into useful things like carbohydrates and oxygen. The problem is that current technologies can only produce molecules with 1 carbon atom. These molecules are too weak to be used for the production of more complex materials. Standard experimental conditions have not been stable enough to allow for molecules with bonds of more than one carbon atom to form.

New research at Osaka City University has found that simply adding metal ions like aluminum and
