Scientists found that certain chemical impurities, such as hydrogen and oxygen, help amorphous carbon form graphite-like, ultralow-friction interfaces under mechanical stress. The findings reveal how impurities can enable self-forming lubricating surfaces, offering a new strategy for designing durable, energy-efficient materials.
Researchers at The University of Osaka have developed novel kirigami structures with periodic parallel inclined cuts. Stretching these materials longitudinally causes them to twist and rotate. Thus, these structures provide a mechanism for coupling tension and rotation. The mechanical deformation of these structures can be characterized in terms of a geometrical property, the chirality. Some of the developed chiral structures were auxetic, longitudinal stretching resulting in lateral expansion, instead of contraction. The findings have applications in soft robotics and soft actuators.
A research team has uncovered a previously unknown RNA-based control system that helps tea plants regulate amino acid production, a process central to tea flavor, nutritional value, and quality.
