Design, analysis and control of a fast nanopositioning stage

2008 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2008
We present a fast flexure-based, piezoelectric stack-actuated XY nanopositioning stage which is suitable for high-speed, accurate nanoscale positioning applications. The performance of the design are analyzed using finite-element-analysis software. Experiments demonstrate that the design has a high first resonant mode at 2.7 kHz, a low cross-coupling ...

Diffractive wavefront correction for Fe L‐edge spectroscopy on the meV scale

Journal of Synchrotron Radiation, EarlyView.
We propose an aberration‐corrected, wavelength‐dispersive instrument for soft X‐ray spectroscopy at an energy‐resolving power of (5–6) × 104, designed for, for example, resonant inelastic X‐ray scattering at synchrotron beamlines or X‐ray free‐electron lasers.We propose a wavelength‐dispersive instrument for high‐resolution soft X‐ray spectroscopy at ...

Characterizing piezoscanner hysteresis and creep using optical levers and a reference nanopositioning stage.

, 2009
International audienceA method using atomic force microscope (AFM) optical levers and a reference nanopositioning stage has been developed to characterize piezoscanner hysteresis and creep. The piezoscanner is fixed on a closed-loop nanopositioning stage,

Characterization and Design Framework for Micro‐ and Nanoscale Printed Metal Interconnects in Hybrid Electronic Systems

Advanced Materials Technologies, Volume 11, Issue 11, 5 June 2026.
This work establishes a framework for high‐resolution printed interconnects by coupling e‐jet printing control, multilayer deposition, and sintering optimization. Ink properties and printing speed influence particle stacking, while different sintering atmospheres drive distinct microstructural evolution.

Optical Skyrmions Modulation Based on Polarization Helicity

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
The polarization helicity represents the global twisted property of the polarization state distribution, it can be used to modulate the spin skyrmion texture in the tight focusing of the radially polarized vortex light. By adjusting the polarization helicity of incident field, the Néel‐Bloch‐Néel transition of the spin skyrmion texture can be realized,

Deterministic hBN Bubbles as a Versatile Platform for Studies on Single‐Photon Emitters

Advanced Functional Materials, Volume 36, Issue 24, 23 March 2026.
Single‐photon emitters (SPEs) in hBN are promising for quantum technologies; however, in exfoliated samples their activation is required, limiting reproducibility of previous studies. This work introduces a large‐area MOVPE‐grown hBN platform that hosts SPEs without prior activation.

Plasmonic Bi‐Cavity Nanostructure for Efficient Light Collection and Localization

Analysis &Sensing, Volume 6, Issue 2, March 2026.
Co‐tuning the plateau and pyramid lengths of a pyramid‐on‐plateau nanostructure creates a hybrid antenna‐cavity that efficiently couples low‐NA excitation and funnels energy to the apex, increasing nano‐Raman signal and enabling TERS in geometries previously inaccessible to high‐NA objectives.Tip‐enhanced Raman spectroscopy (TERS) typically relies on ...

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

Advanced Materials, Volume 38, Issue 6, 27 January 2026.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

Narrow Linewidth Spontaneous and Lasing Emissions from Open‐Access Microcavity‐Embedded Perovskite Quantum Dots

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.
