  • Forward-biased bipolar membranes (FB-BPMs), which recover potential from pH gradients through ion–ion recombination, show promise for application in sustainable devices. The authors use physics-based modeling to elucidate how ion-specific phenomena dictate performance, reveal how selective ion management can mitigate energy losses and provide insights into the rational design of next-generation FB-BPMs.

  • Electrochemical acid-base production has attractive applications in mineral recovery and CO2 removal, but current membrane-based designs are plagued by resistive losses. The authors report a membrane-less system generating useful acid and base solutions at high rates with less energy.

  • Bipolar membranes are increasingly being applied in a variety of electrochemical devices, yet understanding of how they operate in complex electrolyte environments is still limited. Here the authors outline a mechanistic model to explain the behaviour of bipolar membranes in forward bias polarization in mixed electrolytes.

  • Similarities in cancers can be studied to interrogate their etiology. Here, the authors use genome-wide association study summary statistics from six cancer types based on 296,215 cases and 301,319 controls of European ancestry, showing that solid tumours arising from different tissues share a degree of common germline genetic basis.

  • The mechanism by which bimetallic catalysts can outperform their monometallic counterparts is often unexplained. Now nitrate hydrogenation on bimetallic catalysts is shown to proceed via the electrochemical coupling of hydrogen oxidation and nitrate reduction half-reactions, each of which occurs on one metal component.

  • Charge transfer and chemical kinetics both contribute to the overall overpotential that is observed in a typical electrocatalytic experiment, but it remains difficult to resolve the individual contributions. Here a Pd membrane double cell is used to separate the charge transfer and chemical steps in the hydrogen evolution reaction to evaluate how experimental conditions affect the individual steps.

  • Although homogeneous hydride transfer reactivity is well understood, the heterogeneous counterpart at metal surfaces remains rather unexplored. This work introduces the electrocatalytic hydrogen reduction reaction, which in net reduces H2 to reactive hydrides via the intermediacy of surface M−H species. The study reveals that hydride transfer from surface M−H species can be driven by electrical polarization.
