Imaging Cu2O nanocube hollowing in solution by quantitative in situ X-ray ptychography

open access: yesNature Communications, 2022
Observing morphological changes of nanoparticles in solution requires advanced in-situ imaging methods. Here, the authors use X-ray ptychography to image the growth and hollowing of Cu2O nanocubes in 3D.

Bulk Nanocrystalline Thermoelectrics Based on Bi-Sb-Te Solid Solution [PDF]

open access: yes, 2012
A nanopowder from p-Bi-Sb-Te with particles ~ 10 nm were fabricated by the ball milling using different technological modes. Cold and hot pressing at different conditions and also SPS process were used for consolidation of the powder into a bulk ...

Misorientation-angle-dependent electrical transport across molybdenum disulfide grain boundaries

open access: yesNature Communications, 2016
Grain boundaries can degrade the performance of electronic devices made from single atomic layers of transition metal dichalcogenides. Here, the authors combine transport measurements and transmission electron microscopy to find a correlation between ...

Spectral signatures of a unique charge density wave in Ta2NiSe7

open access: yesNature Communications, 2023
Charge Density Waves (CDW) are commonly associated with the presence of near-Fermi level states which are separated from others, or “nested", by a wavector of q.

Current Trends and Future Perspective for Cold Spray Metal‐Ceramic Composites

open access: yesAdvanced Engineering Materials, EarlyView.
The use of cold spray (CS) technology for creating cermet deposits, combining ceramic and metallic components, is advancing rapidly. Cermets offer excellent temperature handling and erosion resistance for diverse applications. This review outlines the current state of the art, focusing on the deposition dynamics and strategies to optimize the ...

Moving beyond bimetallic-alloy to single-atom dimer atomic-interface for all-pH hydrogen evolution

open access: yesNature Communications, 2021
While single, dispersed atoms enable efficient atomic utilization, controllably preparing single-atom dimers remains challenging. Here, authors prepare nickel-cobalt single-atom dimers as high-performance pH-universal H2 evolution electrocatalysts.

Quantum dot dephasing by edge states

open access: yes, 1999
We calculate the dephasing rate of an electron state in a pinched quantum dot, due to Coulomb interactions between the electron in the dot and electrons in a nearby voltage biased ballistic nanostructure.

Wedging Transfer of Nanostructures [PDF]

open access: yesNano Lett., 2010, 10 (5), pp 1912--1916, 2010
We report a versatile water-based method for transferring nanostructures onto surfaces of various shapes and compositions. The transfer occurs through the intercalation of a layer of water between a hydrophilic substrate and a hydrophobic nanostructure (for example, graphene flakes, carbon nanotubes, metallic nanostructures, quantum dots, etc) locked ...
