Metamaterials are products of engineering wizardry. They are made from everyday polymers, ceramics, and metals. And when constructed precisely at the microscale, in intricate architectures, these ordinary materials can take on extraordinary properties.
With the help of computer simulations, engineers can play with any combination of microstructures to see how certain materials can transform, for instance, into sound-focusing acoustic lenses or lightweight, bulletproof films.
But simulations can only take a design so far. To know for sure whether a metamaterial will stand up to expectation, physically testing them is a must. But there’s been no reliable way to push and pull on metamaterials at the microscale, and to know how they will respond, without contacting and physically damaging the structures in the process.
Now, a new laser-based technique offers a safe and fast solution that could speed up the discovery of promising metamaterials for real-world applications.
The technique, developed by MIT engineers, probes metamaterials with a system of two lasers — one to quickly zap a structure and the other to measure the ways in which it vibrates in response, much like striking a bell with a mallet and recording its reverb. In contrast to a mallet, the lasers make no physical contact. Yet they can produce vibrations throughout a metamaterial’s tiny beams and struts, as if the structure were being physically struck, stretched, or sheared.
The engineers can then use the resulting vibrations to calculate various dynamic properties of the material, such as how it would respond to impacts and how it would absorb or scatter sound. With an ultrafast laser pulse, they can excite and measure hundreds of miniature structures within minutes. The new technique offers a safe, reliable, and high-throughput way to dynamically characterize microscale metamaterials, for the first time.
“We need to find quicker ways of testing, optimizing, and tweaking these materials,” says Carlos Portela, the Brit and Alex d’Arbeloff Career Development Professor in Mechanical Engineering at MIT. “With this approach, we can accelerate the discovery of optimal materials, depending on the properties you want.”
Portela and his colleagues detail their new system, which they’ve named LIRAS (for laser-induced resonant acoustic spectroscopy) in a paper appearing today in Nature. His MIT co-authors include first author Yun Kai, Somayajulu Dhulipala, Rachel Sun, Jet Lem, and Thomas Pezeril, along with Washington DeLima at the U.S. Department of Energy’s Kansas City National Security Campus.

This was based off of a #STEMARegional submission by @Ringu_u on Twitter that I selected to include in my region.
I also gave this Carbink an evolution based off of graphene, a single layer of double-bonded carbons.
As with any regional mons that deal with canon ones, these designs are separate from the region, and the Stema Region is not dependent on canon mons.
This is a Carbink that was originally about seismographs and detection of disturbances in the ground. Seismographs often use a pen (or through creative liberty, a pencil) to record any disturbances. Later, a more direct reference to graphite was made where graphite is crystallized carbon, turning into diamond under heat and pressure. Carbon links to itself in sheets and there is a weak Van der Waals force between the sheets. It is so weak that sheets of carbons can come out of the graphite, allowing it to leave a mark behind.
Carbink (Rock/Dark): These Carbinks leave a trail as they move, and if they feel a disturbance in the ground, they leave a zigzag shape. The minerals of these Carbinks come off easily, so they could spray a cloud of graphite powder to run away.
Graphink (Rock/Dark): Graphinks wear a super thin coat which allows them to make little to no sound as they zip around in the dark. Graphinks scout the wild to detect danger which is when they would zigzag back to whoever they are loyal to to warn them.

On the cover: Even the addition or subtraction of a single atom can influence the chemical, physical, and biological properties of nanoscale materials. Via the artwork You, Me, We Are All Parts of NanoWorld (1 to 100 nm), Todd Siler and Geoffrey Ozin reveal how a finite number of 118 known elements, at the nanoscale, can be used to create an infinite number of nanomaterials and practical applications to help us address many of today’s most urgent sustainability challenges. It manifests intuitions and insights into nature’s creative potential: we can build a sustainable future at the nanoscale.

F-Type ATP synthase, a catalytic complex of proteins, synthesizes adenosine triphosphate (ATP), the energy currency of living cells. A lot of ambiguity exists over the rotational mechanism of this spinning enzyme. Now, researchers from Japan have demonstrated how each chemical event of ATP metabolism is linked to the ‘stepwise’ rotational movement of the F1 component of ATPase. Especially, they clarified the angle of shaft rotation before ATP-cleavage, a long-standing enigma, to be 200°.

Congratulations to Moungi Bawendi, the Lester Wolfe Professor of Chemistry at MIT — newly minted Nobel laureate in chemistry! 🥇
MIT chemist Moungi Bawendi shares Nobel Prize in Chemistry
For his work on techniques to generate quantum dots of uniform size and color, Bawendi is honored along with Louis Brus and Alexei Ekimov.
Anne Trafton | MIT News
Moungi Bawendi, the Lester Wolfe Professor of Chemistry at MIT, has won the Nobel Prize in Chemistry for 2023. He will share the prize with Louis Brus of Columbia University and Alexei Ekimov of Nanocrystals Technology.
Bawendi is a pioneer in the development of quantum dots: tiny particles of matter that emit exceptionally pure light. These particles, a special type of semiconducting nanocrystals, have been incorporated into technologies such as biomedical imaging and computer and television displays.
In its announcement this morning, the Nobel Foundation, cited Bawendi for work that “revolutionized the chemical production of quantum dots, resulting in almost perfect particles.”
Quantum dots consist of tiny particles of semiconductor material that are so small that their properties differ from those of the bulk material; they are governed in part by the laws of quantum mechanics that describe how atoms and subatomic particles behave. When illuminated with ultraviolet light, the dots fluoresce brightly in a range of colors determined by the sizes of the particles.
In 1993, Bawendi and his students were the first to report a method for synthesizing quantum dots while maintaining precise control over their size. Since then, he has also devised ways to control the efficiency of the dots’ light emission and to eliminate their tendency to blink on and off, making them more practical for applications in many fields.
