A research team from Skoltech and ITMO university has obtained tunable polariton emission at room temperature on CsPbBr3 perovskite crystals as a promising platform for integration into lateral microchips—a new concept for the integrated all-optical logic that Skoltech researchers are working on.

The research results are presented in the Advanced Optical Materials journal.

Exciton-polaritons are hybridized states of light and matter, which are formed as a result of strong interaction of optical modes of microcavity—photons—with elementary excitations of a material—excitons.

Superionic materials are a class of materials that simultaneously present properties that are characteristic of solids and liquids. Essentially, a set of ions in these materials exhibits liquid-like mobility, even if the materials’ underlying atomic structure maintains a solid-like order.

Due to their unique ionic conductivity patterns, superionic materials could be promising for developing . These are batteries that contain electrolytes based on solid materials instead of liquid electrolytes.

While various past studies have explored the potential of superionic materials as solid-state electrolytes, the physics underpinning their rapid ionic diffusion is not yet fully understood. Specifically, it is unclear whether this property results from liquid-like motion in the material or from the conventional lattice phonons (i.e., atom vibrations) in the material.

Half-metals are unique magnetic compounds that have been attracting interest in the development of mass-storage technologies. Some of the materials in the family of Heusler alloys were predicted to have a half-metallic nature, but their half-metallic electronic structure varies with their composition ratio and atomic ordered structure.

One property, , is fundamental to the material’s half-metallic properties. Spin polarization ratio is a physical property that indicates how polarized the number of electrons with spin in the up and down directions is.

Because spin polarization is influenced by the elemental composition of the Heusler alloy, it’s important to characterize and optimize the atomic composition of Heusler alloys to achieve the highest spin polarization. But current methods for determining the spin polarization of half-metals are either time-consuming or only provide an indirect measure.

Researchers from Oakland University have made a significant breakthrough in the field of optical materials, unveiling the exceptional capabilities of Ba₃(ZnB₅O₁₀)PO₄ (BZBP). Although this transparent crystal closely resembles ordinary window glass, it exhibits extraordinary properties that set it apart from others.

Already renowned for its exceptional qualities, such as excellent heat dissipation, minimal uneven expansion when exposed to temperature changes, and the ability to transmit (a type of light that comes from the sun and other sources like special lamps, but it’s invisible to the human eye), BZBP has emerged as an ideal choice for laser systems operating in deep ultraviolet ranges. These systems are crucial in fields such as medical diagnostics, semiconductor production, and cutting-edge scientific research.

In a study recently published in Advanced Functional Materials, researchers explored how BZBP performs under .

A research team has discovered that by using a new method of “atomic spray painting,” they can tweak the atomic structure of lead-free potassium niobate in order to enhance its ferroelectric properties.

The study, created by a team led by Penn State researchers, explains how molecular beam epitaxy can be employed to deposit atomic layers onto a substrate to create thin films, as a report by SciTechDaily explained.

Using a technique called strain tuning, the researchers adjusted how successive layers are aligned to modify a material’s properties by stretching or compressing the atoms that make up its crystal structure.

Caltech researchers have developed PAMs, a novel material that blends the properties of solids and liquids, making them highly adaptable for diverse applications.

These materials are inspired by chain mail but take structural complexity to new levels, thanks to advanced 3D printing.

Researchers at the University of Maine have managed to 3D print an organic building material with the strength of steel.

The SM2ART Nfloor is printed as a single piece in about 30 hours, which is a third faster than building something comparable by hand according to TechXplore.

The nice thing about this set-up is that these panels can be printed in bulk off-site and get shipped to the construction area. Since there are already channels in the floor for electrical and plumbing, the only other thing that needs to be applied by hand is soundproofing and floor covering.

For the first time, researchers have measured the shape of an electron as it moves through a solid. This achievement could open a new way of looking at how electrons behave inside different materials.

Their discovery highlights many effects that could be relevant to everything from quantum information science to electronics manufacturing.

Those findings come from a team led by physicist Riccardo Comin, MIT’s Class of 1947 Career Development Associate Professor of Physics and leader of the work, in collaboration with other institutions.
