Temporarily apart: Research team succeeds in ultrafast switching of tiny light sources
An international team led by TU Dresden were able to induce an extremely fast switching process between electrically neutral and charged luminescent particles in an ultrathin, effectively 2D material.
High-resolution 2D imaging for graphene devices under high pressure
Researchers led by the University of Science and Technology of China combined nitrogen-vacancy centers in diamond with a diamond anvil cell to achieve noninvasive, high-resolution, 2D imaging of current density and pressure gradient for graphene devices under high pressure.

Spanish nuclear fusion reactor takes a new approach
At the University of Seville in Spain, a team of researchers is putting together a new fusion reactor called the small aspect ratio tokamak, or SMART. Most fusion reactors are based on a doughnut-shaped tokamak machine that confines plasma using magnetic fields. SMART is unique because it is the only tokamak with negative triangularity.
Using antimatter to detect nuclear radiation
Researchers from the University of Sheffield and the University of Hawaii developed a detector that senses and analyzes antineutrinos emitted by nuclear reactors. Capturing and analyzing antimatter particles has shown promise for monitoring what specific reactor operations are occurring, even from hundreds of miles away.
BIOMATERIALS
University of Michigan researchers discovered they can improve bone regeneration by improving cell–matrix interactions via peptide-containing copolymers. Their approach can regenerate about eight times more bone than a scaffold without the special peptides on nanofibers.
Gallium-doped bioactive glass kills 99% of bone cancer cells
Aston University researchers found that bioactive glasses doped with gallium have a 99% success rate of eliminating cancerous cells and can even regenerate diseased bones. Gallium is highly toxic, and the researchers found that the “greedy” cancer cells soak it up and self-kill, which prevents healthy cells from being affected.

Shrinking AR displays into eyeglasses to expand their use
Researchers combined a metasurface and refractive lens with a microLED screen to create a compact, single-lens hybrid augmented reality design. In an eyeglasses prototype, they enhanced image quality with a computer algorithm that removed distortions.
‘Smart choker’ uses AI to help people with speech impairment to communicate
University of Cambridge researchers developed a wearable “smart choker” that allows people with speech impairments to communicate by detecting tiny movements in the throat. The choker is made from a sustainable bamboo-based textile, with strain sensors based on graphene ink incorporated in the fabric.
