| Open AccessDiatomic iron nanozyme with lipoxidase-like activity for efficient inactivation of enveloped virus
Enveloped viruses encased within a lipid bilayer membrane are highly contagious and cause diseases like influenza and COVID-19, so strategies for their prevention and inactivation are needed. Here, the authors develop a diatomic iron nanozyme with lipoxidase-like activity for the inactivation of enveloped viruses, where the diatomic iron sites destroy the viral envelope via lipid peroxidation.

| Open AccessHydrodynamic tearing of bacteria on nanotips for sustainable water disinfection
Common methods for water disinfection involve oxidation or irradiation, and are often associated with a high carbon footprint and formation of toxic byproducts. Here, the authors describe a nano-structured material that is highly effective at killing bacteria in water through a hydrodynamic mechanism driven by mild water flow, in the absence of additional energy supply.

| Open AccessIntelligent non-colorimetric indicators for the perishable supply chain by non-wovens with photo-programmed thermal response
High-performance and low-cost indicators are important in food and cosmetics industry but market uptake is low due to several challenges such as toxicity, cost and unclear reading. Here, the authors report on optically-programmed, non-colorimetric indicators based on nanotextured organic non-wovens, encoded by controlling their cross-linking degree.

| Open AccessHeterogeneously integrated flexible microwave amplifiers on a cellulose nanofibril substrate
Though flexible microwave integrated circuits (MICs) are desirable for the construction of functional microwave amplifier circuits, realizing low cost III-V-based MMICs remains a challenge. Here, the authors report a heterogeneous integration strategy for the fabrication of flexible low-cost MICs.

| Open AccessDistinguishing the sources of silica nanoparticles by dual isotopic fingerprinting and machine learning
Determining the source of nanoparticles is critical for nanotechnology risk assessment. Here, the authors develop an approach that, by taking into account the isotopic signatures of both Si and O, may be able to distinguish between natural and engineered SiO2 nanoparticles, and even those synthesized by different manufacturers.

| Open AccessA Co3O4-CDots-C3N4 three component electrocatalyst design concept for efficient and tunable CO2 reduction to syngas
Simultaneous electrochemical reduction of CO2 and H+/H2O is an attractive renewable route to produce syngas mixtures. Here, the authors introduce a ternary Co3O4-CDots-C3N4 electrocatalyst that couples hydrogen evolution and CO2 reduction catalysts and achieves cheap, stable and tunable production of syngas.
