    Colloidal self-assembly requires carefully balanced particle interactions that are often incompatible with the mechanical disturbances associated with macroscopic-scale manufacturing. Now, a practical bottom-up route has enabled the production of bulk solid materials with nanoscale components.

    Organoclay/DNA semipermeable microcapsules with catalase-powered oxygen gas bubble-dependent buoyancy are prepared and exploited as synthetic protocells capable of programmed motility and sustained oscillatory movement.

    Porous-alumina filter discs typically used to prepare graphene-oxide films are found to corrode during filtration and release aluminium ions that crosslink the negatively charged sheets and make the films insoluble in water. In contrast, aluminium-free graphene-oxide films are significantly weaker and readily disintegrate in water.

    A pH-responsive inorganic membrane has been devised that acts as a gatekeeper for the transport of charged solutes into and out of its interior volume. This behaviour was further used to regulate an enzymatic reaction.

    Colloidal hybrid nanoparticles represent an emerging class of multifunctional artificial molecules. However, unlike actual molecules, their complexity is limited by the lack of a mechanism-driven design framework. Here, nanoparticle analogues of chemoselectivity, regiospecificity, molecular substituent effects, and coupling reactions are used to predictably synthesize hybrid nanoparticle trimers, tetramers, and oligomers.

    It is shown that long-lived reactive oxygen intermediates are formed in heterogeneous reactions of ozone with aerosol particles, resolving apparent discrepancies between earlier quantum mechanical calculations and kinetic experiments. These intermediates play a key role in the chemical transformations and adverse health effects of toxic and allergenic air particulates.
