Is there a shift to “active nanostructures”? [PDF]
Journal of Nanoparticle Research, 2009 It has been suggested that an important transition in the long-run trajectory of nanotechnology development is a shift from passive to active nanostructures. Such a shift could present different or increased societal impacts and require new approaches for risk assessment.

Polymer, 2008 AbstractBlock copolymer modified epoxy resins have generated significant interest since it was demonstrated that the combination could lead to nanostructured thermosets through self-assembly. Over moderate to high polymer concentration the system behaves as expected for a block copolymer in a solvent selective for one block.

Probing defect dynamics in monolayer MoS2 via noise nanospectroscopy
Nature Communications, 2017 The intrinsic properties of atomically thin MoS2 are believed to be strongly affected by the presence of structural defects; however, the underlying physical mechanism of such link is not fully understood. Here, the authors combine noise-current analysis

First-principles based analysis of thermal transport in metallic nanostructures: size effect and Wiedemann-Franz law [PDF]
Phys. Rev. B 103, 104301 (2021), 2020 Metallic nanostructures (the nanofilms and nanowires) are widely used in electronic devices, and their thermal transport properties are crucial for heat dissipation. However, there are still gaps in understanding thermal transport in metallic nanostructures, especially regarding the size effect and validity of the Wiedemann-Franz law.

High-Velocity Shear and Soft Friction at the Nanometer Scale
Frontiers in Mechanical Engineering, 2021 We study high-speed friction on soft polymer materials by measuring the amplitude dependence of cyclic lateral forces on the atomic force microscope (AFM) tip as it slides on the surface with fixed contact force.
