Molecular engineers have triggered a domino-like structural transition in an organic semiconductor. The energy- and time-saving phenomenon may enhance the performance of smartwatches, solar cells, and other organic electronics.

A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC). The discovery promises to deepen scientists' understanding of the nature of neutrinos, which are among the most abundant particles in the universe and key to the solution of the question why there is more matter than antimatter.

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.

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.

A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials -- like a tailor altering a suit -- could be just the tool for designing the technology of a sustainable energy future. Researchers have developed a method for structurally splitting, editing and reconstituting layered materials, called MAX phases and MXenes, with the potential of producing new materials with very unusual compositions and exceptional properties.

New research has shown that a strong coupling of light and material increases the colour brilliance of OLED displays. This increase is independent of the viewing angle and does not affect energy efficiency.

Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth's core, where temperatures exceed 5,000-degrees C. New research from geophysicists suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities -- or anomalies, as scientists call them -- of the Earth's magnetic field.

In organic solar cells, carbon-based polymers convert light into charges that are passed to an acceptor. Scientists have now calculated how this happens by combining molecular dynamics simulations with quantum calculations and have provided theoretical insights to interpret experimental data.

Researchers have engineered a material with the potential to dramatically cut the amount of heat power plants release into the atmosphere.

In an unlikely pairing, a chemist and an astrophysicist applied the tools of statistical mechanics to find similarities in spatial patterns across length scales.

Scientists succeeded in directly observing how LECs -- which are attracting attention as one of the post-organic LEDs -- change their electronic state over time during field emission by measuring their optical absorption via lamp light irradiation for the first time. This research method can be applied to all light-emitting devices, including not only LECs but also organic LEDs. This method is expected to reveal detailed electroluminescence processes and lead to the early detection of factors that reduce the efficiency of electroluminescence.

Scientists have transformed single-cell algae into functional perovskite materials. The team has converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by conventional synthetic production. The method can be applied to the mass production of perovskites with tunable structural and electro-optical properties from single-celled organisms.
