The absence of piezoelectricity in silicon can lead to direct electromechanical applications of the mainstream semiconductor material. The integrated electrical control of silicon mechanics can open new perspectives for on-chip actuators. In a new report, Manuel Brinker and a research team in physics, materials, microscopy and hybrid nanostructures in Germany, combined wafer-scale nanoporosity in single-crystalline silicon to synthesize a composite demonstrating macroscopic electrostrain in aqueous electrolytes. The voltage-strain coupling was three-orders of magnitude larger

Study Finds Preserved Brain Material In Vesuvius Victim

Brain cells have been found in exceptionally preserved form in the remains of a young man killed in the eruption of Mount Vesuvius almost 2,000 years ago, an Italian study has revealed.

The preserved neuronal structures in vitrified or frozen form were discovered at the archaeological site of Herculaneum, an ancient Roman city engulfed under a hail of volcanic ash after nearby Mount Vesuvius erupted in the year 79.

“The study of vitrified tissue as the one we found at Herculaneum… may save lives in future,” study lead author Pier Paolo Petrone, forensic anthropologist at Naples’ University Federico II, told AFP in English.

“The experimentation continues on several research fields, and the data and information we are obtaining will allow us to clarify other and newer aspects of what happened 2000 years ago during

Scientists find evidence of exotic state of matter in candidate material for quantum computers

Scientists find evidence of exotic state of matter in candidate material for quantum computers

The twisted octahedra formed by chlorine around the electron spin of each ruthenium atom are mirror images of each other. This twist is key to the compound’s unusual behavior, which is evidence that it may contain an example of a quantum spin liquid.

Using a novel technique, scientists working at the Florida State University-headquartered National High Magnetic Field Laboratory have found evidence for a quantum spin liquid, a state of matter that is promising as a building block for the quantum computers of tomorrow.


Researchers discovered the exciting behavior while studying the so-called electron spins in the compound ruthenium trichloride. Their findings, published today in the journal Nature Physics , show that electron spins interact across the material, effectively lowering

Tesla unveils battery puzzle pieces of smart material science, design, and manufacturing innovation

At its Battery Day event, Tesla unveiled its new 4680 battery cell developed in-house and the manufacturing process behind it.

The highly anticipated presentation went deep into details about all the different pieces of material science, design, and manufacturing innovations that it took to deliver the masterpiece of a puzzle that the automaker needed to put together to reduce battery costs by more than 50% in just 3 years…

Over the last few years, Tesla has been making a lot of moves related to batteries.

We are talking about buying companies like Maxwell and Hibar, and applying for patents on new technology, like a tabless battery cell and a cell to pack design.

While all these moves were mostly evaluated on their own merits, it wasn’t clear how all those things would fit together.

That’s exactly what Tesla demonstrated at its Battery Day.

Tesla explained how they have made major
