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.
Heirloom uses cheap and widely available limestone to suck carbon from the air. The latest funds will help build its first pilot-scale facility.
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.

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.

Coating implantable electronics in the polymer PEDOT can extend their life, which could make more common in the future.
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.
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.
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.
Scientists are getting better at making neurone-like junctions for computers that mimic the human brain’s random information processing, storage and recall. Fei Zhuge of the Chinese Academy of Sciences and colleagues reviewed the latest developments in the design of these “memristors” for the journal Science and Technology of Advanced Materials.
Computers apply artificial intelligence programs to recall previously learned information and make predictions. These programs are extremely energy-and time-intensive: typically, vast volumes of data must be transferred between separate memory and processing units. To solve this, researchers have been developing computer hardware that allows for more random and simultaneous information transfer and storage, much like the human brain.
Electronic circuits in these “neuromorphic” computers include memristors that resemble the synaptic junctions between neurones. Energy flows through a material from one electrode to another, much like a neurone firing a signal across the synapse to the next neurone. Scientists are now finding ways to better tune this intermediate material so the information flow is more stable and reliable.
