    Aqueous batteries have a short lifespan due to Al current collector corrosion and Li loss from side reactions on the anode. Here, the authors propose a prototype of self-prolonging aqueous Li-ion batteries by introducing hydrolyzation-type anodic additives to regulate Al corrosion-passivation.

    In lithium-metal batteries, it is vital to quantify electrolyte side reactions occurring at the metal anode surface. Here, the authors introduce an electrochemical technique, using a series of small-step lithium deposition followed by open circuit voltage analysis, to accurately measure these reactions.

    A low-cost and efficient high-temperature oxygen evolution reaction electrode is a big challenge. Here, the authors report an iron-base electrode with an in situ formed lithium ferrite for enhanced stability and catalytic activity in molten carbonate and chloride salts and achieve kiloampere-scale electrolysis.

    The corrosion properties of engineering alloys are strongly influenced by local variations seen at the micro level. Here, the authors demonstrate how the metal grain orientation can influence the protectiveness of the oxide, which provides a possible route for improving corrosion performance.

    Understanding how pores evolve in metals submerged in molten salts is important for nanofabrication technology and molten salt corrosion in nuclear and solar power plants. Here, the authors present an in situ X-ray 3D imaging to directly visualize and quantify the process.

    Understanding metal oxide growth mechanisms is essential for the precise design and fabrication of nanostructured oxides. Here, the authors use correlated in situ ETEM, data analysis, and DFT to show an unusual layer-by-layer adatom growth mechanism of 3D epitaxial Cu2O nano-islands, regardless of substrate orientation.

    Dissolution of Ir catalysts varies widely between PEM water electrolysers and aqueous electrolytes. Here, we systematically investigate this finding and propose that stabilization of the catalysts over time and overestimated ionomer acidity are the main contributors to the dissolution discrepancy.

    Better understanding the synergy between radiation and corrosion is necessary to deploy advanced nuclear reactors. Here, the authors contradict the misconception that radiation always results in deleterious effects and show that proton irradiation slows the corrosion of Ni-Cr alloys in 650 °C molten salt.

    While the conversion of greenhouse CO2 to chemical fuels offers a promising renewable energy technology, there is a dire need for new materials. Here, authors report the largest CO2 photocathode search using a first-principles approach to identify both known and unreported candidate photocatalysts.

    Magnesium alloys usually have poor corrosion resistance, which inhibits their use in the automotive and biomedical industries. Here, the authors use an environmental TEM to carbonate the natural corrosion products at the surface of magnesium alloys and form a compact and protective surface layer.

    Exactly how hydrogen renders metals brittle is still unclear, and it remains a challenge to predict component failure due to hydrogen embrittlement. Here, the authors identify a class of grain boundaries in a nickel superalloy that deflects propagating cracks and improves alloy resistance to hydrogen.

    Collecting experimental evidence of chloride ion attack on protective passive metallic films due to corrosion remains challenging. Here, the authors show that the boundaries between nanocrystals and amorphous regions in the passive film ease chloride transport even as they do not coincide with areas of high chloride concentration.

    Understanding how catalysts corrode during use is crucial in developing new, durable devices. Here, the authors studied the real-time corrosion of core-shell palladium-platinum nanocubes by electron microscopy and found two competitive etching mechanisms to dominate catalyst degradation behavior.

    Conventional dealloying methods to produce bicontinuous open nanoporous structures for catalysis are limited to very few alloys and produce chemical waste. Here, the authors develop a green process, vapor-phase dealloying, to selectively remove high partial vapor pressure components and create nanoporosity in a wide range of alloys.

    Hydrogen gas can drive detachment of protective surface oxides from metal substrates and this process is accelerated at moderately elevated temperatures relevant to applications. Here the authors use environmental transmission electron microscopy to monitor associated void coalescence processes and clarify roles that diffusion and hydrogen-vacancy complexes play.

    Surface modification techniques can allow metals to be used in aggressive environments for emerging applications. Here authors demonstrate an ultrafast process for aluminizing austenitic stainless steels and propose an electromigration-assisted mechanism suggesting generalizability of the method.

    Given the scarcity and cost of platinum, it is important to develop sustainable processes for its recycling. Here, the authors report the dissolution of metallic platinum using reductive and oxidative gases to repetitively change its surface oxidation state, in the absence of an external electric current.

    Liquid metal dealloying produces topologically complex nanoporous structures, however little is known about how they form. Here, the authors use mesoscale phase-field modeling and experiments to show that structure formation is governed by both interfacial spinodal decomposition and diffusion-coupled growth.

    The long term durability of silicate glasses is of significant importance, not least due to applications in nuclear waste repositories. Here, the authors study glass corrosion and show that its rate drops as a passivating layer forms via a self-healing mechanism.
