| Open AccessUnidirectional alignment and orientation pinning mechanism of h-BN nucleation on Ir(111) via reactive probe atomic force microscopy
The epitaxial growth of large-scale single-crystalline 2D materials requires precise control over crystallographic orientation and morphology during the initial stages of nucleation. Here, noncontact atomic force microscopy and density functional theory provide atomic-scale mechanistic insights into the nucleation of hexagonal boron nitride on Ir(111).

| Open AccessDisentangling surface atomic motions from surface field effects in ultrafast low-energy electron diffraction
Ultrafast low-energy electron diffraction allows the direct observation of atomic motions in structural transitions, but is accompanied by a strong photoinduced emission resulting in surface field effects. Here, these effects are quantified, enabling the isolation of the structural dynamics of interest.

| Open AccessCoexistence of carbonyl and ether groups on oxygen-terminated (110)-oriented diamond surfaces
Chemical vapor deposition of diamond typically results in the faster growth of the (110) facet, but achieving large-area and high-quality surfaces is challenging and requires post-growth processing. Here, the authors present a systematic characterization of the structure and stability of oxygen-terminated diamond (110) surfaces.

| Open AccessMultispectral electromagnetic shielding using ultra-thin metal-metal oxide decorated hybrid nanofiber membranes
Shielding materials are crucial in protecting devices against electromagnetic radiation but are often heavyweight and operate in narrow frequency ranges. Here, highly conductive, lightweight, ultrathin, and flexible membranes based on Ag-WO3-coated polymeric nanofibers provide multispectral shielding from microwaves to X-rays.

| Open AccessElectron dynamics of tip-tunable oxygen species on TiO2 surface
Oxygen species on a TiO2 surface exist in different redox states, which can be switched between by electron tunneling with an atomic force tip. Here, a fast experimental setup enables statistically significant tunneling rates to be determined, revealing changes in electronic structure.

| Open AccessResidual polymer stabiliser causes anisotropic electrical conductivity during inkjet printing of metal nanoparticles
Inkjet printed metal nanoparticles are known to have lower electrical conductivity than those produced by traditional approaches. Here, anisotropic electrical conductivity is attributed to organic residuals from the metal nanoparticle ink, reducing conductivity.
