Open AccessEfficient electrochemical reduction of nitrate to ammonia over metal-organic framework single-atom catalysts
The design and preparation of efficient catalysts for ammonia production under mild conditions is a desirable but highly challenging target. Here, we report a series of single-atom catalysts [M-SACs, M = Mn(II...

Revisiting metal fluorides as lithium-ion battery cathodes
Metal fluorides, promising lithium-ion battery cathode materials, have been classified as conversion materials due to the reconstructive phase transitions widely presumed to occur upon lithiation. We challenge...

Open AccessAnalysis of structural distortion in Eshelby twisted InP nanowires by scanning precession electron diffraction
Transmission electron microscopes (TEM) are widely used in nanotechnology research. However, it is still challenging to characterize nanoscale objects; their small size coupled with dynamical diffraction makes...

Open AccessUnsupervised machine learning applied to scanning precession electron diffraction data
Scanning precession electron diffraction involves the acquisition of a two-dimensional precession electron diffraction pattern at every probe position in a two-dimensional scan. The data typically comprise man...

Open AccessReducing dynamic disorder in small-molecule organic semiconductors by suppressing large-amplitude thermal motions
Thermal vibrations and the dynamic disorder they create can detrimentally affect the transport properties of van der Waals bonded molecular semiconductors. The low-energy nature of these vibrations makes it di...

Measurement of molecular motion in organic semiconductors by thermal diffuse electron scattering
Many of the remarkable electrical and optical properties of organic semiconductors are governed by the interaction of electronic excitations with intra- and intermolecular vibrational modes. However, in specif...
