Helical foldamers are a class of artificial molecules that fold into well-defined helical structures like helices found in proteins and nucleic acids. They have garnered considerable attention as stimuli-responsive switchable molecules, tuneable chiral materials, and cooperative supramolecular systems due to their chiral and conformational switching properties.

Double-helical foldamers exhibit not only even stronger chiral properties but also , such as the transcription of chiral information from one chiral strand to another without chiral properties, enabling potential applications in higher-order structural control related to replication, like nucleic acids.

However, the artificial control of the chiral switching properties of such artificial molecules remains challenging due to the difficulty in balancing the dynamic properties required for switching and stability. Although various helical molecules have been developed in the past, reversal of twist direction in double-helix molecules and supramolecules has rarely been reported.

A groundbreaking study using sub-daily GPS has improved our understanding of early afterslip following earthquakes, offering a more accurate assessment of seismic hazards and enhancing emergency response and preparedness strategies.

A groundbreaking study has revealed new insights into the Earth’s crust’s immediate behavior following earthquakes. Researchers have utilized sub-daily Global Positioning System (GPS) solutions to accurately measure the spatial and temporal evolution of early afterslip following the 2010 Mw 8.8 Maule earthquake. This innovative approach marks a significant advancement in seismic analysis, offering a more precise and rapid depiction of ground deformations, which is essential for assessing seismic hazards and understanding fault line activities.

The aftermath of an earthquake is marked by intricate postseismic adjustments, particularly the elusive early afterslip. Daily seismic monitoring has struggled to capture the rapid and complex ground movements occurring in the critical hours post-quake. The intricacies of these initial activities and their profound implications for seismic hazard assessment highlight an urgent need for more refined and immediate monitoring techniques.
