TLDR
In this article, the authors discuss progress in the design, synthesis, and functioning of photochemical and electrochemical switches and chemical and light-driven molecular motors and discuss the anchoring of molecular motors on surfaces and molecular motors at work.Abstract:
Molecular switches and motors are essential components of artificial molecular machines. In this perspective, we discuss progress in our design, synthesis, and functioning of photochemical and electrochemical switches and chemical and light-driven molecular motors. Special emphasis is given to the control of a range of functions and properties, including luminescence, self-assembly, motion, color, conductance, transport, and chirality. We will also discuss our efforts to control mechanical movement at the molecular level, a feature that is at the heart of molecular motors and machines. The anchoring of molecular motors on surfaces and molecular motors at work are discussed.read more

Chirality and Chiroptical Effects in Plasmonic Nanostructures: Fundamentals, Recent Progress, and Outlook
TL;DR: This Progress Report highlights four different strategies which have been used to achieve giant chiroptical effects in chiral nanostructures, and presents two examples of chiral switches, where switching the chirality of incoming light causes a reversal of the handedness in the nanostructure.

TL;DR: By solving the convection-diffusion equation in the frame of the moving rod, it was found that the interfacial tension force scales approximately as SR(2)gamma/muDL, where S is the area-normalized oxygen evolution rate, gamma is the liquid-vapor interfacial pressure, R is the rod radius, mu is the viscosity, D is the diffusion coefficient of oxygen, and L is the length of the rod.
