    Biological rotary motors can alter their mechanical function by changing the direction of rotary motion. Now, researchers have designed a synthetic light-driven rotary motor in which the direction of rotation can be reversed on command by changing the chirality of the molecular motor through base-induced epimerization.

    Controlling the movements of molecular systems through external stimuli is crucial for the construction of nanoscale mechanical machines. A spring-like compound has now been prepared — a double helicate that retains its handedness under ion-triggered extension and contraction.

    Glass is widely used as an electrical insulator in electrodes, but in spite of its high resistance, 100-nm-thick layers of glass have now been shown to be sufficiently conductive for electrochemical measurements. Obtaining redox couples through glass-covered nanoelectrodes suggests that the pH response of the glass is due to the formation of a hydrogel layer in acidic solution.
