A breakthrough in predicting chaotic results in the three body system

  • 3 תגובות
New research from the Larkach Institute of Physics reveals a significant advance in chaos theory, by confirming in detail the flux-based statistical theory that predicts chaotic outcomes in non-hierarchical Newtonian three-body systems. This breakthrough has practical implications for fields such as celestial mechanics, astrophysics and particle dynamics.

Caption: Above, azobenzene is a molecule that can change its shape with light. An azobenzene molecule switches between two forms under the influence of light. In the lower figure: a molecular cage containing the molecules of the photosensitizer azobenzene. The new mechanism is based on a supramolecular approach in which the molecules of azobenzene and the photosensitizer are locked together in a molecular cage. The limited space accessible to the caged molecules allows only the E-form, but not the Z-form of azobenzene, so this molecule is pushed out of the cage. Credit: Jonathan R. Church

Publication in Science magazine about a new discovery: using harmless light to change the shape of an azobenzene molecule within a supramolecular complex

  • 2 תגובות
Azobenzenes are versatile compounds with many potential uses, such as advancing technology through the production of tiny machines, as well as creating light-activated drugs. These molecules can be found in two different forms called "E" and "Z" which can be exchanged between them through irradiation. However, under irradiation conditions both forms are in equilibrium, which prevents optimal utilization for different applications
