- Three simple steps to make the longest graphene nanoribbon ever 17/08/2023 A Lego-like synthesis previously produced record-breaking nanoribbons of 30, then 53 fused rings. Now, a similar ‘accelerated’ modular methodology made a molecular nanoribbon that is triple the longest ever made – in just three simple steps. The gargantuan graphene nanoribbon is almost 36nm long, featuring 147 linearly linked rings and a conjugated core of 920 atoms. The first experiments, although preliminary, promise great applications in electronics and optoelectronics, thanks to fluorescence features that outperform state-of-the-art quantum dots.

- Photonic time crystals could open the door to a new branch of optics 08/08/2023 Refractive index—the ratio of the speed of electromagnetic radiation in a medium to its speed in a vacuum—can be modulated fast enough to generate photonic time crystals (PTCs) in the near-visible part of the spectrum, a new study published in the journal Nanophotonics demonstrates. The study's authors suggest that the ability to sustain PTCs in the optical domain could have profound implications for the science of light, enabling truly disruptive applications in the future.

- New study reveals spin in quantum dots' carrier multiplication 18/07/2023 A new approach to developing semiconductor materials at tiny scales could help boost applications that rely on converting light to energy. A Los Alamos-led research team incorporated magnetic dopants into specially engineered colloidal quantum dots—nanoscale-size semiconductor crystals—and was able to achieve effects that may power solar cell technology, photo detectors and applications that depend on light to drive chemical reactions.
- 3D pattern generation via chemical vapor deposition of ceramic eutectic system for novel solid-state phosphors 13/07/2023 The eutectic structure of metals and ceramics occurs when multiple solid phases solidify from a liquid phase, forming a three-dimensional (3D) pattern through a self-organizing phenomenon. Traditionally, it was believed that eutectic structures could only be obtained through a melt-solidification process.
- Researchers develop a new source of quantum light 11/07/2023 Using novel materials that have been widely studied as potential new solar photovoltaics, researchers at MIT have shown that nanoparticles of these materials can emit a stream of single, identical photons.
- Researchers demonstrate single-molecule electronic 'switch' using ladder-like molecules 06/07/2023 Researchers have demonstrated a new material for single-molecule electronic switches, which can effectively vary current at the nanoscale in response to external stimuli. The material for this molecular switch has a unique structure created by locking a linear molecular backbone into a ladder-type structure. A new study finds that the ladder-type molecular structure greatly enhances the stability of the material, making it highly promising for use in single-molecule electronics applications.
- Discovering features of band topology in amorphous thin films 04/07/2023 In recent years, scientists have been studying special materials called topological materials, with special attention paid to the shape, or topology, of their electronic structures (electronic bands). Although it is not visible in real space, their unusual shape in topological materials produces various unique properties that can be suitable for making next-generation devices.
