Batteries: Passivation layer mystery solved      (via sciencedaily.com) 

In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.

Surprise in the quantum world: Disorder leads to ferromagnetic topological insulator      (via sciencedaily.com) 

Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10 from the manganese bismuth telluride family. The amazing thing about this quantum material is that its ferromagnetic properties only occur when some atoms swap places, introducing antisite disorder.

Can synthetic polymers replace the body's natural proteins?      (via sciencedaily.com) 

Scientists developing new biomaterials often try to mimic the body's natural proteins, but a chemist shows that simpler polymers -- based on a handful of plastic building blocks -- also work well. Using AI, her team was able to design polymer mixtures that replicate simple protein functions within biological fluids. The random heteropolymers dissolve and stabilize proteins and can support cells' normal protein-making machinery. The technique could speed the design of materials for biomedical applications.

Mountain forests are being lost at an accelerating rate, putting biodiversity at risk      (via sciencedaily.com) 

More than 85% of the world's bird, mammal, and amphibian species live in mountains, particularly in forest habitats, but researchers report that these forests are disappearing at an accelerating rate. Globally, we have lost 78.1 million hectares (7.1%) of mountain forest since 2000 -- an area larger than the size of Texas. Much of the loss occurred in tropical biodiversity hotspots, putting increasing pressure on threatened species.

Another crystalline layer on crystal surface as a precursor of crystal-to-crystal transition      (via sciencedaily.com) 

Ice surfaces have a thin layer of water below its melting temperature of 0 degrees Celsius. Such premelting phenomenon is important for skating and snowflake growth. Similarly, liquid often crystallizes into a thin layer of crystal on a flat substrate before reaching its freezing temperature, i.e. prefreezing. The thickness of the surface layer usually increases and diverges as approaching the phase transition (such as melting and freezing) temperature. Besides premelting and prefreezing, whether similar surface phenomenon exists as a precursor of a phase transition has rarely been explored. Scientists now propose that a polymorphic crystalline layer may form on a crystal surface before the crystal-crystal phase transition and names it pre-solid-solid transition.
