    When a solid object is placed in a supersaturated environment, it can exhibit interesting dynamics. Spagnolie et al. conducted an experiment using raisins and 3D-printed bodies in carbonated water and found that the motion of the solid object is influenced by the accumulation and release of bubbles as they reach the surface.

    Selective nanofiltration membranes with accurate molecular sieving offer a solution to recover rare metals and other valuable elements from brines but this demands the development of membranes with precise sub-nanometer pores surpassing those available today. Here, the authors report a scalable approach for membrane fabrication in which functionalized macrocycles are seamlessly oriented via supramolecular interactions during the interfacial polycondensation on a polyacrylonitrile support layer.

    Catalyst activation commonly occurs during reactions. This study demonstrates that the surface’s active structure in nitride catalysts during the reverse water gas-shift reaction varies with the partial pressure of reaction products, resulting in enhanced catalytic activity through positive feedback between catalytic activity and the evolution of MoNx’s active structure.

    Understanding the complex relationships between enzyme sequence, folding stability and catalytic activity is essential for applications, but current technologies cannot simultaneously resolve both stability and activity phenotypes and couple these to gene sequences at large scale. Here, the authors report Enzyme Proximity Sequencing (EP-Seq), a deep mutational scanning method to assay both expression level and catalytic activity of thousands of oxidoreductase variants from a cellular pool in a single experiment.
