The effect of ageing on the electrical charge harvesting capacity of polydimethylsiloxane (PDMS)-based triboelectric nanogenerators is interrogated through dielectric and mechanical characterization at micro- and nanoscale resolutions. Nanospectroscopic study reveals the physicochemical mechanism underpinning the evolution of interfacial properties...

The so-called buoy-effect, that is, the targeted surface enrichment of a Pt catalyst dissolved in ionic liquids (ILs), is achieved by attaching perfluorinated alkyl chains to the ligand system, which drags the metal complex toward the interface. Using angle-resolved X-ray photoelectron spectroscopy, the study demonstrates how this surface enrichment...

The influence of carbon toward epitaxial h-BN growth is examined using high-resolution microscopy. For most of the film, carbon induced a polytype transition from h-BN to local r-BN to turbostatic-BN ending epitaxial growth. In some localized BN structures, carbon is absent, here the epitaxial film growth is sustained to higher thickness with a uniform...

BaTiO3/La1- x Sr x MnO3 superlattice is fabricated to investigate the intimately coupled interfacial effects. Unconventional spin and orbital moments of Ti are induced by the charge transfer from Mn to the empty conduction band of Ti. The Mn orbital reconstruction modifies the magnetic exchange coupling between Mn–Ti and Mn–Mn at the interfaces,...

Insights into interaction between H2O and LiNi0.5Mn1.5O4 (LNMO) are studied using a thin-film model system. The reactivity of this active material with H2O is evaluated at different lithiation states, showing that protonation of the active material in aqueous environments is purely electrochemically driven, and only affects partially delithiated LNMO....
