Local charge trapping in conjugated polymers resolved by scanning Kelvin probe microscopy [PDF]

, 2009
The microstructure of conjugated polymers is heterogeneous on the length scale of individual polymer chains, but little is known about how this affects their electronic properties.

Thermal‐Ionic Coupling in Transpiration‐Inspired Janus Nanofiber Membranes: Synergistic Dry‐Wet Interface Engineering for Solar‐Driven Electricity Generation

Advanced Science, EarlyView.
A transpiration‐inspired Janus nanofiber membrane creates a persistent dry‐wet interface that couples localized solar heating with hydration‐induced ion regulation. The asymmetric architecture sustains directional water and ion transport, suppresses salt accumulation, and enables simultaneous seawater evaporation and stable electricity generation ...

Combined scanning probe electronic and thermal characterization of an indium arsenide nanowire

Beilstein Journal of Nanotechnology, 2018
As electronic devices are downsized, physical processes at the interface to electrodes may dominate and limit device performance. A crucial step towards device optimization is being able to separate such contact effects from intrinsic device properties ...

A Comparative Investigation on the Corrosion Behavior of cast and rolled ZG21 Mg Alloys

International Journal of Electrochemical Science, 2017
ZG21 Mg alloys exhibit excellent deformation ability at room temperature. However, their corrosion behavior lacks sufficient investigation. The relationship between the second phases and micro-galvanic corrosion of ZG21 Mg alloys has been investigated ...

Intergranular corrosion of TiNb-microalloyed martensitic stainless steels processed by quenching and partitioning

Journal of Materials Research and Technology
This study investigates the localised corrosion mechanisms in laboratory-processed Q&P-treated martensitic stainless steels. Two steel variants, one NbTi-free (alloy B) and the other micro-alloyed with Nb and Ti (alloy M) were investigated to elucidate ...

Scanning Kelvin probe microscopy on organic field-effect transistors during gate bias stress [PDF]

, 2007
The reliability of org. field-effect transistors is studied using both transport and scanning Kelvin probe microscopy measurements. A direct correlation between the current and potential of a p-type transistor is demonstrated.

The Effect of Ligand Reactivity and Carrier Mechanics on Thiol‐Mediated Cellular Uptake for miRNA Nano‐Drugs

Advanced Science, EarlyView.
The effect of ligand reactivity and carrier mechanics on thiol‐mediated uptake was investigated at the single‐molecule/particle level. The interaction kinetics of LA and AspA with membrane thiols were quantified; AspA is more efficient due to the higher binding affinity, greater binding stability, and more double‐disulfide binding, as well as greater ...
