Scientists have long strived to develop artificial molecular motors that can convert energy into directed motion. Researchers have now presented a solution to a challenging problem: how motion can be transferred in a controlled manner from one place to another through a 'molecular gear'. Molecular motors have the potential for use in, for example, energy storage applications and medicine.

Perchlorate compounds are known for their explosive nature. To understand what makes these compounds so explosive, a team of researchers developed a novel deep learning-based method that analyses their crystal structure and molecular interactions to elucidate their physical properties. This novel technique avoids dangerous laboratory-based experiments and uses data to study the nature of compounds. Overall, the study marks a significant step towards data-driven and artificial intelligence-based methods for chemical research.

Chemists have developed an autonomous chemical synthesis robot with an integrated AI-driven machine learning unit. Dubbed 'RoboChem', the benchtop device can outperform a human chemist in terms of speed and accuracy while also displaying a high level of ingenuity. As the first of its kind, it could significantly accelerate chemical discovery of molecules for pharmaceutical and many other applications.

Scientists have developed a universal method for producing a wide variety of designed metallic and semiconductor 3D nanostructures -- the potential base materials for next-generation semiconductor devices, neuromorphic computing, and advanced energy applications. The new method, which uses a 'hacked' form of DNA that instructs molecules to organize themselves into targeted 3D patterns, is the first of its kind to produce robust nanostructures from multiple material classes.

Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.

Researchers found that understanding the stability of the rings of atoms in glass materials can help them predict the performance of glass products. This capability is important because the most widely used glass is silicate glass, which consists of different sizes of atomic rings connected in three dimensions.

Researchers have performed the world's first life cycle assessment (LCA) of an existing, two-seater, all-electric aircraft, with a direct comparison to an equivalent fossil fuel-powered one. According to the study, after just one quarter of the expected lifespan of the electric aircraft, the climate impact is lower than that of the fossil fuel-based aircraft, provided that green electricity is used. The downside, however, is increased mineral resource scarcity.
