A new platform for controlled design of printed electronics with 2D materials

Scientists have shown how electricity is transported in printed 2D materials, paving the way for design of flexible devices for healthcare and beyond. A study, published today in Nature Electronics, led by Imperial College London and Politecnico di Torino researchers reveals the physical mechanisms responsible for the transport of electricity in printed two-dimensional (2D) materials.…

Solar power: ‘Wonder material’ phosphorene nanoribbons live up to hype in first demonstration

Researchers have incorporated phosphorene nanoribbons into new types of solar cells, dramatically improving their efficiency. Phosphorene nanoribbons (PNRs) are ribbon-like strands of the 2D material phosphorus, which, similar to graphene, are made of single-atom-thick layers of atoms. PNRs were first produced in 2019, and hundreds of theoretical studies have predicted how their properties could enhance…

Nanodiamonds are key to efficient hydrogen purification: Nanodiamonds may be tiny, but they can help with one of the biggest problems facing humanity today: Climate change

Nanodiamonds may be tiny, but they can help with one of the biggest problems facing humanity today: Climate change. Hydrogen, a clean-burning fuel, leaves nothing but water when consumed. Many countries view hydrogen as a way to a zero-carbon future, but switching to a hydrogen economy requires its production to be much more affordable than…

Retraction of the Research Article: “A universal cooperative assembly-directed method

In the research article, “A universal cooperative assembly-directed method for coating of mesoporous TiO2 nano shells with enhanced lithium storage properties” (1), we reported a universal cooperative assembly method for growing mesostructured TiO2 shells on diverse functional particles. Recently, we found two duplicated images (Fig. 3A, Fig.S17A) in two figures that were published previously in…

New method to measure spin waves brings us one step closer to spin superfluidity

Spin waves, a change in electron spin that propagates through a material, could fundamentally change how devices store and carry information. These waves, also known as magnons, don’t scatter or couple with other particles. Under the right conditions, they can even act like a superfluid, moving through a material with zero energy loss. But the…

Long-Range Balanced Electron- and Hole-Transport Lengths in Organic-Inorganic CH3NH3PbI3

In the past 2 years, organolead halide perovskites have emerged as a promising class of light-harvesting media in experimental solar cells, but the physical basis for their efficiency has been unclear (see the Perspective by Hodes). Two studies now show, using a variety of time-resolved absorption and emission spectroscopic techniques, that these materials manifest relatively…

Novel Nano-Filter Removes Anionic and Cationic Dyes from Wastewater

Every day, globally, synthetic dyes are released into wastewater and as a result pollute the environment, calling for sophisticated methods of water purification. Researchers from Korea, Russia, and India have worked collaboratively to create a nano-filter method that can effectively remove synthetic dyes from wastewater.   Image Credit: Shutterstock / Peter Milto The nano-filter was…

First firm evidence for ferroelectric ice

Scientists have for the first time unambiguously observed ferroelectric water – a state in which the molecules’ dipoles become ordered and the material gains electric polarisation – in an atom-thin ice layer sandwiched between graphene sheets. In analogy to ferromagnetic materials, which exhibit a permanent magnetic moment, ferroelectric materials show spontaneous electric polarisation in the…
