Physicists Startled To Discover a New Way To Shape a Material’s Atomic Structure With Light

Posted by in categories: materials, physics

X-ray laser experiments show that intense light distorts the structure of a thermoelectric material in a unique way, opening a new avenue for controlling the properties of materials.

Thermoelectric materials convert heat to electricity and vice versa, and their atomic structures are closely related to how well they perform.

Now researchers have discovered how to change the atomic structure of a highly efficient thermoelectric material, tin selenide, with intense pulses of laser light. This result opens a new way to improve thermoelectrics and a host of other materials by controlling their structure, creating materials with dramatic new properties that may not exist in nature.

Large-scale synthesis of graphene and other 2D materials towards industrialization

Posted by in categories: futurism, materials

The industrial application of two-dimensional (2D) materials strongly depends on the large-scale manufacturing of high-quality 2D films and powders. Here, the authors analyze three state-of-the art mass production techniques, discussing the recent progress and remaining challenges for future improvements.

Scientists create a fabric that can hear

Posted by in category: materials

Scientists have created a piece of fabric that can hear.


The new study reimagines the response of fabric to sound, however. Researchers made it out of a material that turns any movement of the fabric into an electrical signal – and it can do that with sounds.

In testing, the fabric was able to pick up a wide variety of sounds, vibrating in proportion with the noises that happened around it. “This shows that the performance of the fiber on the membrane is comparable to a handheld microphone,” said Grace Noel, a co-author on the paper.

How Graphene will Save Moore’s Law

Posted by in categories: computing, materials

While many say that Moore’s Law is dead, scientists are hard at work discovering new semiconductor materials which will help increase CPU and GPU performance well into the 2030’s right on track of Moore’s Laws exponential properties. Companies such as TSMC and Intel could use Graphene to make the smallest possible transistors and much improve their efficiency as electricity prices skyrocket. 2nm or 1nm processors might soon come out.

Future cities could be 3D Printed using Recycled Glass

Posted by in categories: futurism, materials

Future cities could be 3D printed – using concrete made with recycled glass.

3D printed concrete may lead to a shift in architecture and construction. Because it can be used to produce new shapes and forms that current technologies struggle with, it may change the centuries-old processes and procedures that are still used to construct buildings, resulting in lower costs and saved time.

Scientists Discover Promising New Electrolyte for Solid-State Lithium-Ion Batteries

Posted by in categories: energy, materials

New battery material offers promise for the development of all-solid batteries.

In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flammable.

As a result, solid-state lithium-ion batteries, which consist of entirely solid components, have become increasingly attractive to scientists because they offer an enticing combination of higher safety and increased energy density — which is how much energy the battery can store for a given volume.

NASA opens sample taken from the Moon 50 years on

Posted by in categories: materials, space

The Apollo missions to the Moon brought a total of 2,196 rock samples to Earth. But NASA has only just started opening one of the last ones, collected 50 years ago.

For all that time, some tubes were kept sealed so that they could be studied years later, with the help of the latest technical breakthroughs.

NASA knew “science and technology would evolve and allow scientists to study the material in new ways to address new questions in the future,” Lori Glaze, director of the Planetary Science Division at NASA Headquarters, said in a statement.
