Scientists have developed 'supramolecular ink,' a new 3D-printable OLED (organic light-emitting diode) material made of inexpensive, Earth-abundant elements instead of costly scarce metals. The advance could enable more affordable and environmentally sustainable OLED flat-panel displays as well as 3D-printable wearable technologies and lighting.

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant move towards the ultimate goal of reaching the quantum ground state of sound in wave-guides. Unwanted noise generated by the acoustic waves at room temperature can be eliminated. This experimental approach both provides a deeper understanding of the transition from classical to quantum phenomena of sound and is relevant to quantum communication systems and future quantum technologies.

Researchers have developed a light-based means of printing nano-sized metal structures that is 480 times faster and 35 times cheaper than the current conventional method. It is a scalable solution that could transform a scientific field long reliant on technologies that are prohibitively expensive and slow. Their method is called superluminescent light projection (SLP).

Non-Heisenberg-type approximant crystals have many interesting properties and are intriguing for researchers of condensed matter physics. However, their magnetic phase diagrams, which are crucial for realizing their potential, remain completely unknown. Now, a team of researchers has constructed the magnetic phase diagram of a non-Heisenberg Tsai-type 1/1 gold-gallium-terbium approximant crystal. This development marks a significant step forward for quasicrystal research and for the realization of magnetic refrigerators and spintronic devices.

Researchers have developed a material to remove urea from water and potentially convert it into hydrogen gas. By building these materials of nickel and cobalt atoms with carefully tailored electronic structures, the group has unlocked the potential to enable these transition metal oxides and hydroxides to selectively oxidize urea in an electrochemical reaction. The team's findings could help use urea in waste streams to efficiently produce hydrogen fuel through the electrolysis process, and could be used to sequester urea from water, maintaining the long-term sustainability of ecological systems, and revolutionizing the water-energy nexus.

A team has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microkelvin in the thermal Hall effect. Previously, these temperature differences could not be measured quantitatively due to thermal noise. Using the well-known terbium titanate as an example, the team demonstrated that the method delivers highly reliable results. The thermal Hall effect provides information about coherent multi-particle states in quantum materials, based on their interaction with lattice vibrations (phonons).
