Nanographenes are organic semiconductor materials used in smartphones, OLED displays, and solar cells. At the molecular level, they are composed of polycyclic aromatic hydrocarbons (PAHs) which are a network of connected benzene rings (hexagon-shaped carbon molecules). Chemists can modify the electronic properties of PAHs by adding more benzene rings to them, changing their size and shape. As such, there is high demand for methods that can selectively extend specific sites of PAH molecules to allow greater versatility in technological applications. New research from Nagoya University introduces a new methodology for developing PAH molecules that has elucidated chemists for years.

Hole structures in advanced components are common sites of fatigue crack initiation. A new hole-strengthening method, Hertz contact rotation expansion processing (HCR-EP), improves surface integrity in Inconel 718 superalloy while avoiding the trade-offs of conventional techniques. Interrupted fatigue tests reveal that compressive residual stress relaxation is the dominant factor governing fatigue life improvement under high-temperature service conditions.

Researchers developed a new artificial intelligence (AI) technique that could help overcome a major bottleneck in the development of large-scale quantum computers. The method enables automated analysis of key measurement data used in semiconductor spin qubits.

Researchers from The University of Osaka have discovered a new class of antibodies, called iTabs, that naturally suppress specific immune responses by blocking immune cell activation. These antibodies can reduce autoimmune disease severity in mice, suggesting a new way to treat conditions like multiple sclerosis without weakening the immune system overall.Researchers from The University of Osaka have discovered a new class of antibodies, called iTabs, that naturally suppress specific immune responses by blocking immune cell activation.

Magnesium hydride stores lots of hydrogen but the problem comes with the high temperatures needed to release it. Now, researchers have found a new catalyst that helps solve this common bottleneck, focusing on a phenomenon called the burst effect.

A once-theoretical structure is now shaping the future of computing. Researchers have uncovered key properties of magnetic skyrmions, ultra-stable, 2 nm vortex-like structures that could enable next-gen memory with extremely low power consumption. Even more surprising? They can form in materials once thought impossible.

Researchers are investigating how 3D printers could achieve unprecedented levels of precision when creating batteries, opening the door for new innovations.
