For the first time: "smart liquids" will be used as sensitive biological sensors

The team of researchers explained that the uniqueness of the smart liquids is that, as a result of their chemical properties, the liquids maintain separation from each other, thus creating distinct droplets
A photograph of the fracture surface in a silicone model, across both fracture planes, shows that the crack profile has a certain curvature

Secrets, cracks and fractures

It turns out that the shorter a crack in brittle materials - the more resistant they are to it, which can help in the design and use of applications that are based on brittle materials

Computer simulations showed that changing the coverage of the monolayer changed the smoothness of the surface. Both low coverage and high coverage produced very slippery surfaces, but for different reasons. [Source: Sakari Lepikko et al 2023]

The smoothest surface ever created

  • No comments
The smoothness of a surface can be adjusted by changing its roughness at the molecular level - this is how researchers from Finland demonstrate

Researchers synthesized a stable C16 carbon ring, although theoretically it should have broken down immediately

  • One response
Before the successful synthesis, it was not clear if it was even possible to create such a molecule and keep it stable long enough to study its structure and its electronic properties.
- Spin laser on an atomic scale: the image describes the laser resonator structure consisting of two types of nanoantenna structures. The radiation is trapped in the internal structure only (yellow). The active layer of the laser - a single atomic layer - is on the resonator. The laser beam is split into two beams by the opposite spins of the photons (light particles), which can be controlled with the help of the laser pump (credit: Scholardesigner co, LTD).

In the center you can see the true atomic arrangement in the material in an electron microscope image. At the bottom of the picture you can see how the various efforts change the structure of the energy levels in the material and therefore also the way the electrons arrange themselves in it. By controlling these properties, the researchers intend to engineer these materials into future transistors. Photo: Nitzan Zohar, Technion Spokesperson

"Sliding and climbing between electrical polarizations": The periodic crystal structure contains a pair of atoms at regular intervals in each horizontal layer. Each additional layer can be slid to the right or left in the horizontal plane to place a blue atom exactly above a red atom or vice versa, thereby bouncing electrons with an electrical charge up or down between the layers. Unlike in polarized crystals known so far, the electric potential in the new system changes in a constant and well-defined value between each step. It is possible to climb in a controlled manner between all the different options, that is, it is possible to switch between the information units in the same crystal in contrast to a pair of modes in previous technologies.
