Electric fields catalyse graphene’s energy and computing prospects

Posted by in categories: chemistry, computing, sustainability

Researchers at the National Graphene Institute have made a groundbreaking discovery that could revolutionise energy harnessing and information computing. Their study, published in Nature (“Control of proton transport and hydrogenation in double-gated graphene”), reveals how electric field effects can selectively accelerate coupled electrochemical processes in graphene.

Electrochemical processes are essential in renewable energy technologies like batteries, fuel cells, and electrolysers. However, their efficiency is often hindered by slow reactions and unwanted side effects. Traditional approaches have focused on new materials, yet significant challenges remain.

The Manchester team, led by Dr Marcelo Lozada-Hidalgo, has taken a novel approach. They have successfully decoupled the inseparable link between charge and electric field within graphene electrodes, enabling unprecedented control over electrochemical processes in this material. The breakthrough challenges previous assumptions and opens new avenues for energy technologies.

McDonald’s will end AI drive-through partnership with IBM

Posted by in categories: business, finance, robotics/AI

McDonald’s (MCD) will put an end to its AI drive-thru partnership with IBM (IBM) in late July as many customer complaints over botched orders began to mount. The fast-food chain does have plans to continue implementing AI into its business model down the line.

The Morning Brief Anchors Brad Smith and Seana Smith break down the latest developments for McDonald’s and what it means for the company moving forward.

Discovery of one-dimensional topological insulator

Posted by in categories: quantum physics, solar power, sustainability

A joint research team has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors. Unlike most known TIs, which are either three-or two-dimensional, this TI is one-dimensional. The breakthrough will lead to further developments of qubits and highly efficient solar cells.

Details of the research were published in the journal Nature (“Observation of edge states derived from topological helix chains”).

TIs boast an interior that behaves as an electrical insulator, meaning electrons cannot easily move; Whereas its surface acts as an electrical conductor, with the electrons able to move along the surface.

The dark side of transmission X-ray microscopy

Posted by in categories: energy, nanotechnology

X-ray microscopes are essential for examining components and materials because they can be used to detect changes and details in the material. Until now, however, it has been difficult to detect small cracks or tiny inclusions in the images. By developing a new method, researchers at the Helmholtz-Zentrum Hereon are now able to visualize such changes in the nanometer regime. In particular materials research and quality assurance will profit from this development.

The team reported on their new development in the scientific journal Optica (“Nanoscale dark-field imaging in full-field transmission X-ray microscopy”).

The quality must be right. This also applies to materials science. When metal parts are welded together, you need to know whether the weld seam is any good — or whether small cracks or pores have formed inside, which could lead to failure. High-performance materials, e.g. for electrodes in electric car batteries or fuel cells, should not contain defects to allow the current to flow undisturbed.
