    Membranes allowing transfer of a gas between a liquid and gas layer have applications in areas such as blood oxygenation and carbon dioxide capture. Here, a super liquid repellent membrane is fabricated, allowing high gas transfer and also avoiding wetting and clogging of the membrane pores.

    Platinum is a widely studied catalyst for the reduction of protons to hydrogen in water splitting, but it also catalyses the competing hydrogen oxidation back-reaction, thus limiting efficiency. Here, the authors show that the back-reaction can be limited by tuning the platinum oxidation state.

    Methane is a major constituent of planetary interiors, yet phase relations in the C–H system are poorly understood. This work documents the chemical reactivity of the C–H system over a wide range of temperatures and pressures, and sheds light on the chemical composition of Earth and icy giants.

    The mechanical properties of brittle materials are largely determined by how cracks propagate through them. Contrary to expectations, Kermodeet al.show that a crack propagating below a critical speed through a silicon crystal can be scattered by a single isolated boron impurity.

    Colorimetric differentiation of solvents is difficult as many solvatochromic molecules exhibit broad overlaps in their absorption and emission bands. Here, the authors present a ‘turn-on’ type sensor in which the colorimetric sensor responds only when its protective layer is disrupted by a specific solvent.

    Efficient and economical water splitting is desirable for energy conversion, but it is limited by high overpotential and the need for noble metals. Zhao et al. report that nitrogen-doped graphite materials function as a promising electrocatalyst, with efficiency comparable to that of benchmark metal oxides.

    A physical description of supercritical fluids remains challenging because common approximations for solids and gases do not apply to liquids. Bolmatov et al. identify a liquid/gas dynamic crossover of specific heat above the critical point, and formulate a theory to shed light on its nature.

    Crystalline porous materials are commonly based around negatively charged frameworks, so ion-exchange is limited to cations. Here, the authors report a series of positive metal-organic frameworks, capable of ion exchange of large organic anions, with potential in separation and purification applications.

    Techniques for shape-controlling of hydrogels, that is, crosslinked networks of polymers, could make possible various biomimetic applications. Palleau et al.propose a strategy to pattern three-dimensional hydrogels using electric potential, which allows directed bending and fast controllable actuation.

    Ultrafast laser pulses are useful to study electron dynamics in chemical bonds, but their influence on bond breaking is not fully understood. Wu et al. study H2 bond breaking with coincidence techniques, and find a phase-dependent anisotropy of the H+fragmentation even for isotropic multicycle laser pulses.
