Direct Observation of Contact Electrification Effects at Nanoscale Using Scanning Probe Microscopy

Contact electrification on the polydimethylsiloxane is investigated, using peak force tapping atomic force microscopy with an operation mode resembling a vertical-type triboelectric nanogenerator. The subsequent surface potential and tip-sample current measurements reveal that the created tribocharge can be controlled by both peak amplitude, frequency...

Sub‐Micron Thickness Self‐Limiting Electrospray Deposition via Voltage Bias of Spray Target

Sub-micron coating thickness via electrospray deposition is achieved through implementing a voltage bias onto the target. By doing so, the charged droplets are deterred from depositing onto the target, thus decreasing the coating thickness. This technique also has the potential to reintroduce self-limiting behavior, thus being useful for applications...

High‐Performance Mesoporous Catalysts of Ultrasmall Hexagonal Thiospinel Nanocrystals for Visible‐Light Hydrogen Evolution

High-surface-area mesoporous frameworks comprising linked hexagonal CdIn2S4 nanocrystals are elaborately synthesized. These nanoporous architectures offer prominent advantages for light-induced catalysis owing to the enhanced interfacial charge-transfer kinetics, high crystallinity, small grain size and large accessible surface area. Ni2P functionalization...

Hybrid Foams based on Multi‐Walled Carbon Nanotubes and Cellulose Nanocrystals for Anisotropic Electromagnetic Shielding and Heat Transport

Hybrid foams with aligned macropore channels based on multi-walled carbon nanotubes (MWCNT) and cellulose nanocrystals (CNC) revealed a high and orientation-dependent electromagnetic (EM) shielding efficiency and displayed a highly anisotropic thermal conductivity. The anisotropic lightweight CNC-MWCNT foams can enable directional heat transport and...

Contactless Scanning Near‐Field Optical Dilatometry Imaging at the Nanoscale

A novel scanning near-field optical dilatometer is presented, which is contactless and capable of generating maps of both positive and negative thermal expansion coefficients of 2D materials and nanostructured thin-films at the nanoscale. This dilatometer is based on super-resolution scanning near-field optical microscopy (SNOM) and, therefore, has...
