Quasi-ballistic electron transport in double-wall carbon nanotubes
, 2004 Room-temperature quasi-ballistic electron transport in double-wall carbon nanotubes (DWNT) is demonstrated. Conductance dependence on the length was measured by submerging DWNTs into liquid mercury.

Stability margins and model-free control: A first look [PDF]
, 2014 We show that the open-loop transfer functions and the stability margins may be defined within the recent model-free control setting. Several convincing computer experiments are presented including one which studies the robustness with respect to delays ...

Journal of Synchrotron Radiation, Volume 32, Issue 4, Page 1068-1084, July 2025.A dispersive X‐ray absorption spectroscopy instrument has been developed and implemented at the Advanced Photon Source's Advanced Spectroscopy Beamline. The instrument uses a convexly bent Bragg‐crystal analyzer to disperse a polychromatic X‐ray beam and independent Kirkpatrick–Baez mirrors for focusing, thereby providing a simple and flexible method ...

Electronic mean free path in as-produced and purified single-wall carbon nanotubes
, 2005 The effect of purification on room temperature electronic transport properties of single-wall carbon nanotubes (SWNT) was studied by submerging samples into liquid mercury.

Nanophotonics, Volume 14, Issue 11, Page 1817-1826, June 2025.Abstract Europium‐doped nanocrystals constitute a promising material for a scalable future quantum computing platform. Long‐lived nuclear spin states could serve as qubits addressed via coherent optical transitions. In order to realize an efficient spin‐photon interface, we couple the emission from a single nanoparticle to a fiber‐based microcavity ...

Electron spin resonance of nitrogen-vacancy centers in optically trapped nanodiamonds
, 2012 Using an optical tweezers apparatus, we demonstrate three-dimensional control of nanodiamonds in solution with simultaneous readout of ground-state electron-spin resonance (ESR) transitions in an ensemble of diamond nitrogen-vacancy (NV) color centers ...

Small, Volume 21, Issue 5, February 5, 2025.The complex charge carrier dynamics of promising carbon nitride photocatalysts make optimization challenging. Here spatial heterogeneity is discovered using transient absorption microscopy on carbon nitride particles from the same synthetic batch. This indicates that there are at least two distinct defect types that control the charge carrier dynamics,
