Hybrid colloidal suprastructures and superlattices are assembled by exploring depletion forces to selectively control the interactions between colloidal particles.

Deployment of proton-exchange membrane fuel cells is limited by the durability of Pt-nanoscale catalysts during cathodic oxygen reduction reactions. Dissolution processes on single crystalline and thin film surfaces are now correlated leading to the design of PtAu catalysts with suppressed dissolution.

Nanosized zeolites enable better catalytic performance; however, their synthesis is non-trivial. Here, a simple treatment is presented that enables the growth of nanosized fins on zeolites that act as pseudo-nanoparticles, reducing deactivation rates for methanol-to-hydrocarbon catalysis.

Developing cheap and sustainable aqueous electrolytes with a wide voltage window is key to achieving safe and high-energy Li-ion batteries. An electrolyte using the polymer poly(ethylene glycol) as a crowding agent to decrease water activity achieves a wide operation window at low salt concentration.

Optimized Ullmann coupling reaction of heterotriangulene precursors allows the synthesis of two-dimensional π-conjugated polymers, with ordered domains larger than 100 × 100 nm2 showing both Dirac cones and flat bands in their electronic structure.

Prompted by advances in the programmability of DNA nanostructures and their hybridization, the complexity of nanomaterial lattices guided by DNA continues to increase.

Bi2TeI is identified as a dual topological insulator. It is a weak topological insulator with metallic states at the (010) surfaces and a topological crystalline insulator at the (001) surfaces.

The dominant mechanism of nanoparticle entry into solid tumours has now been shown to be an active trans-endothelial pathway rather than the currently established passive transport via inter-endothelial gaps.

Nuclear instability in laminopathies Lamin mutations responsible for muscular dystrophy are shown to reduce nuclear envelope stability, resulting in mechanically induced nuclear envelope rupture, DNA damage and activation of DNA damage response pathways that lead to muscle cell death. Preventing nuclear envelope damage by reducing cytoskeletal forces on the nucleus improves muscle fibre health and function.

Protein channels are highly selective, but application in membranes is limited due to low protein content. Here, protein channels are embedded into block copolymers to form nanosheets using rapid solvent casting, with better water permeability and similar molecular exclusions relative to other membrane systems.

From optoelectronic to biomedical and energy storage applications, the interest in organic mixed ionic–electronic conductors is expanding. This Review describes current understanding of the processes occurring in these materials and their structure–property relations.
