Researchers produce conductive MXene ink to print micro-supercapacitors. Researchers from Drexel University and Trinity College in Ireland, have created ink for an inkjet printer from a highly conductive type of 2D material called MXene. Recent findings, published in Nature Communications, suggest that the ink can be used to print flexible energy storage components, such as supercapacitors, in any size or shape.

Conductive inks have been around for nearly a decade and they represent a multi-hundred million-dollar market that is expected to grow rapidly into the next decade...

Hydrogen is a clean and renewable energy carrier that can power vehicles, with water as the only emission. Unfortunately, hydrogen gas is highly flammable when mixed with air, so very efficient and effective sensors are needed...

Patterned on a microchip and working in ambient conditions, the atoms could lead to rapid advancements in new quantum-based technology. By drilling holes into a thin two-dimensional sheet of hexagonal boron nitride with a gallium-focused ion beam, University of Oregon scientists have created artificial atoms that generate single photons.

The artificial atoms – which work in air and at room temperature – may be a big step in efforts to develop all-optical quantum computing, said UO physicist Benjamín J. Alemán, principal investigator of a study published in the journal Nano Letters.

Tiny, individual, flexible ribbons of crystalline phosphorus have been made by UCL researchers in a world first, and they could revolutionise electronics and fast-charging battery technology.

Since the isolation of 2D phosphorene, which is the phosphorus equivalent of graphene, in 2014, more than 100 theoretical studies have predicted that new and exciting properties could emerge by producing narrow ‘ribbons’ of this material. These properties could be extremely valuable to a range of industries.

In a study published today in Nature, researchers from UCL, the University of Bristol, Virginia Commonwealth and University and École Polytechnique Fédérale de Lausanne, describe how they formed quantities of high-quality ribbons ...
