At the water's edge: Self-assembling 2D materials at a liquid–liquid interface

The past few decades have witnessed a great amount of research in the field of two-dimensional (2D) materials. As the name implies, these thin film-like materials are composed of layers that are only a few atoms thick. Many ...

Study shows that skyrmions and antiskyrmions can coexist at different temperatures

Matching particles and antiparticles are small units of matter that have the same mass but opposite electric charges. Typically, these units of matter with opposite electric charge tend to annihilate one another.

Study reveals yunnanozoans as the oldest known stem vertebrates

Scientists have long puzzled over the gap in the fossil record that would explain the evolution from invertebrates to vertebrates. Vertebrates, including fishes, amphibians, reptiles, birds, mammals, and humans, share unique ...

Novel catalyst radically enhances rate of conversion of carbon dioxide into solar fuels

Carbon dioxide or CO2 can potentially be used as a feedstock to be converted into carbon-neutral "solar fuels" that store energy from the sun. But for them to be competitive with fossil fuels, the chemical reaction that performs ...

Giant bacteria found in Guadeloupe mangroves challenge traditional concepts

At first glance, the slightly murky waters in the tube look like a scoop of stormwater, complete with leaves, debris, and even lighter threads in the mix. But in the Petri dish, the thin vermicelli-like threads floating delicately ...

2D interfaces in future transistors may not be as flat as previously thought

Transistors are the building blocks of modern electronics, used in everything from televisions to laptops. As transistors have gotten smaller and more compact, so have electronics, which is why your cell phone is a super ...
