Stacked up against the rest      (via sciencedaily.com)     Original source 

Scientists have hypothesized that moir excitons -- electron-hole pairs confined in moir interference fringes which overlap with slightly offset patterns -- may function as qubits in next-generation nano-semiconductors. However, due to diffraction limits, it has not been possible to focus light enough in measurements, causing optical interference from many moir excitons. To solve this, researchers have developed a new method of reducing these moir excitons to measure the quantum coherence time and realize quantum functionality.

Green hydrogen: 'Artificial leaf' becomes better under pressure      (via sciencedaily.com)     Original source 

Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.

What no one has seen before -- simulation of gravitational waves from failing warp drive      (via sciencedaily.com)     Original source 

Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the realm of science fiction, it is based on concrete descriptions in general relativity. A new study takes things a step further -- simulating the gravitational waves such a drive might emit if it broke down.

Organic nanozymes have broad applications from food and agriculture to biomedicine      (via sciencedaily.com)     Original source 

Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.
