A team of scientists led by crystallographers from St Petersburg University has succeeded in synthesizing an analog of the Earth’s most structurally complex mineral, ewingite, in a laboratory. The findings of the research are published in Materials.

Ewingite is a mineral that was discovered in the mid-2010s in the abandoned Plavno uranium mine located in the Czech Republic. It is the most complex mineral known to exist on Earth. Moreover, because of the specific thermodynamic conditions required for its formation, the mineral is considered to be very rare.

The researchers managed to synthesize an analog with a composition and crystal structure similar to that of natural ewingite through a combination of low-temperature hydrothermal synthesis and room-temperature evaporation.

Tiny magnetic whirlpools could transform memory storage in high performance computers.

Magnets generate invisible fields that attract certain materials. A common example is refrigerator magnets. Far more important to our everyday lives, magnets also can store data in computers. Exploiting the direction of the magnetic field (say, up or down), microscopic bar magnets each can store one bit of memory as a zero or a one—the language of computers.

Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory want to replace the bar magnets with tiny magnetic vortices. As tiny as billionths of a meter, these vortices are called skyrmions, which form in certain magnetic materials. They could one day usher in a new generation of microelectronics for memory storage in high performance computers.

What is graphene? Why has it taken researchers so long to discover it? Is it truly the material of the future?

This is the first time scientists have observed vessels form with such a close resemblance to the complicated structure of naturally occurring blood vessels.

An international research collaboration headed by the University of Sydney has created technology that allows for the production of materials that mirror the structure of living blood vessels, with major implications for the future of surgery.

Preclinical research showed that once the manufactured blood vessel was transplanted into mice, the body accepted it and new cells and tissue began to develop in the appropriate locations, thereby converting it into a “living blood vessel.”

What’s more, it can simultaneously capture information about the orientation, or “polarization,” of the waves in real-time, which existing devices cannot.

This information can be used to characterize materials that have asymmetrical molecules or to determine the surface topography of materials.

Researchers at Purdue University have discovered new waves with picometer-scale spatial variations of electromagnetic fields that can propagate in semiconductors like silicon. The research team, led by Dr. Zubin Jacob, Elmore Associate Professor of Electrical and Computer Engineering and Department of Physics and Astronomy, published their findings in Physical Review Applied in a paper titled “Picophotonics: Anomalous Atomistic Waves in Silicon.”

“The word microscopic has its origins in the length scale of a micron, which is a million times smaller than a meter. Our work is for light matter interaction within the picoscopic regime which is far smaller, where the discrete arrangement of atomic lattices changes light’s properties in surprising ways,” says Jacob.

These intriguing findings demonstrate that natural media host a variety of rich light-matter interaction phenomena at the atomistic level. The use of picophotonic waves in semiconducting materials may lead researchers to design new, functional optical devices, allowing for applications in quantum technologies.
