A new study, led by Dr. Shayanti Mukherjee at the Australian Hudson Institute (a leading Australian translational medical research institute), has found that perovskites materials can have anti-microbial properties, without toxic side effects to human cells.

Dr Mukherjee and her team, who already have a significant program researching new bio-degradable nanomeshes to revolutionize treatments for pelvic organ prolapse (POP), have shown for the first time that perovskites can be used as additives to engineer human tissue implants.

Australia-based RRAM developer 4DS Memory announced that it has raised a total of $7.6 million AUD ($5.45 million USD) in two financing round. The 4DS memory cell is constructed using an advanced perovskite material, which has the same crystal structure as the inorganic compound calcium titanium oxide.

4DS Memory says that it will use the funds to further develop its Interface Switching ReRAM technology with imec and Western Digital's subsidiary, HGST.

In a recent report, Camilo X. Quintela and an international group in materials science, physics and engineering in the U.S., Norway, China and South Korea proposed a novel direction for materials design based on nitride antiperovskite and oxide perovskite crystals.

In this work, they successfully layered perovskites and antiperovskites together, to create an interface with unique electrical properties for applications in a new class of quantum materials.

Scientists at UC San Diego have developed a new method to fabricate perovskites as single-crystal thin films, which are more efficient for use in solar cells and optical devices than the current state-of-the-art polycrystalline forms of the material.

Their fabrication method - which uses standard semiconductor fabrication processes - results in flexible single-crystal perovskite films with controlled area, thickness, and composition. These single-crystal films showed fewer defects, greater efficiency, and enhanced stability than their polycrystalline counterparts, which could lead to the use of perovskites in solar cells, LEDs, and photodetectors.

Researchers at Cornell University have analyzed the overall environmental impact of two types of solar panels, comparing these against panels made with crystalline silicon wafers – the current industry standard.

The team found that a solar panel made from two layers of perovskite requires a smaller total energy input and results in fewer carbon emissions. The panel, a perovskite-perovskite tandem, contains two layers of the material on top of each other, each optimized to absorb a section of the electromagnetic spectrum.
