Notably, the Ag (NA) 2– embedded [2]-rotaxane exhibits the best NLO performance with the highest nonlinear absorption coefficient and the lowest limiting threshold, outperforming some reported organic ...

Researchers have created a nanoscale system that might be used to deliver drugs or release molecules that repair damaged materials (Nature 2024, DOI:10.1038/s41586 ...

Synthetic latex films are widely used across many fields, but they usually contain harmful additives to enhance their strength. In a recent study, researchers have developed a new class of latex films ...

In this review article, we discuss the synthesis and dynamic nature of macromolecular systems that have mechanically linked polymer chains capable of undergoing a topology transformation driven by a ...

Rotaxanes are molecules with a two-component structure: a dumbbell-shaped part (the ‘axle’) threaded through a ring-like part (the ‘wheel’). The two components are normally not chemically bound but ...

Rotaxanes derived from synthetic peptide macrocycles and nonpeptidic diammonium threads have been prepared by chemists at the University of Edinburgh, Scotland (J. Am ...

Artificial muscles can be made with cables on pulleys, driven by heat, or twisted together from carbon nanotubes. Subscribe to read this story ad-free Get unlimited access to ad-free articles and ...

Researchers have demonstrated the design and synthesis of a smart globular macromolecular machine vehicle for actively controlled cancer drug delivery, which would enhance the drug's efficacy. Hong ...
