  • Two-dimensional perovskites enable high efficiency in perovskite photovoltaics but compromise operational stability. Yaghoobi Nia et al. form two-dimensional perovskite co-crystals with neutral templating molecules, improving the stability of perovskite solar modules.

  • Surface charge patchiness has a great impact on the aggregation and solution stability of colloidal particles and globular proteins. Here, the authors report the solution behaviours of computationally designed peptide coiled-coil ‘bundlemer’ nanoparticles with controlled surface charge patchiness where only a single type of surface charge is allowed.

  • Cathodic corrosion of platinum is investigated using operando high-resolution X-ray absorption spectroscopy matched with density functional calculations. Platinum hydrides are found to be reaction intermediates in conditions at which these species are expected to be unstable.

  • Efficient and pathogen-specific antifungal agents are required to mitigate drug resistance problems. Here the authors present a series of cationic small molecules, which are easy to isolate and characterize, and which can self-assemble to give polymer-like antifungal activity and specificity.

  • Mechanisms that drive highly explosive eruptions of low-viscosity magmas, such as at Sunset Crater volcano, remain uncertain. Here, the authors present evidence for an exsolved CO2 phase ~15 km beneath Sunset Crater that was the critical driver of rapid magma ascent leading to the explosive eruption.

  • The mammalian oocyte cell cycle is regulated by massive zinc fluxes which culminate in coordinated ejections of ~1010 zinc ions at fertilization. Four single-cell physiochemical approaches (live-cell fluorescence imaging, scanning transmission electron microscopy with energy dispersive spectroscopy, X-ray fluorescence microscopy and tomography) reveal that these ‘zinc sparks’ originate from thousands of cortical vesicles which each release ~106 zinc ions.

  • The role of clonal evolution on the actionable proteome and response to therapy in childhood acute lymphoblastic leukemia (ALL) remains unknown. Here, targeted sequencing and proteomic analysis of paired ALL diagnosis and relapsed samples revealed PARP1 as a potential therapeutic target.

  • Female carriers of BRCA1 mutations possess high breast cancer risk, which may reflect deficient growth control of mammary progenitor cells. Here, the authors study progenitor-enriched fractions from these carriers and describe a loss of PLK1-mediated mitotic spindle positioning and an inability of the progeny to acquire features of mature luminal cells.

  • The effect of hyaluronan-mediated motility receptor (HMMR) expression in BRCA1-associated breast cancer risk remains unknown. Here, HMMR overexpression induces the activation of cGAS-STING and non-canonical NF-κB signalling, instigating an immune permissive environment for breast cancer development.

  • Although the Grotthuss mechanism of proton transfer is generally considered to be the most efficient means of proton transport, the search for experimental evidence of the mechanism has remained elusive and in certain cases confusing. Here, dielectric spectroscopy, quasieleastic neutron and light scattering, along with ab initio molecular dynamics simulations have been utilized to elucidate the mechanism of proton transfer in pure and 85% aqueous phosphoric acid.

  • Photo-stimulated luminescence spectra (PSLS) emission from alumina-filled epoxy nanocomposites consisting of varying volume fractions of alumina nanoparticles was collected and analyzed to characterize dispersion within the sample through intensity maps. The measurements are based on integrated intensity data from the R1 curve of α-alumina throughout each specimen. This novel method has potential as a quality control method to determine the location of voids, inclusions and/or agglomerations, while in addition predicting the volume percentage of particles within a specimen.
