    MoS2 quantum dots synthesized with the new approach can potentially generate cancer-killing properties. NUS Engineers have developed a cost-effective and scalable strategy for designing tiny semiconductor particles known as transition metal dichalcogenide quantum dots (TMD QDs) which can potentially generate cancer-killing properties. The team is also looking to optimise TMD QDs for applications such as the next generation TV and electronic device screens, advanced electronics components and even solar cells.

    Structures can contract, reshape and grab objects while floating on water. Researchers at North Carolina State University have created 3D-printed flexible mesh structures that can be controlled with applied magnetic fields while floating on water. The structures can grab small objects and carry water droplets, giving them the potential to be useful as soft robots that mimic creatures living on water surfaces or that can serve as tissue scaffolds for cell cultures.

    “This research shows capabilities in the emerging field of combining 3D printing and soft robotics,” said Orlin Velev, S...

    Engineers at the University of Maryland (UMD) have created the first 3D-printed fluid circuit element so tiny that 10 could rest on the width of a human hair. The diode ensures fluids move in only a single direction — a critical feature for products like implantable devices that release therapies directly into the body.

    An international team led by the University of Liverpool and McMaster University has made a significant breakthrough in the search for new states of matter. In a study published in the journal Nature Physics, researchers show that the perovskite-related metal oxide, TbInO3, exhibits a quantum spin liquid state, a long-sought-after and unusual state of matter.

    Using cutting-edge experimental technologies, including inelastic neutron scattering and muon spectroscopy, researchers discovered that the exotic quantum state in TbInO3 emerges from the complexity of the local environment around the magnetic ions in the material, ...
