3D Position Nanometrology of a Coronavirus-like Nanoparticle with Topologically Structured Light

Conference on Lasers and Electro-Optics, 2022
Scattering of topologically structured light is highly sensitive to the position of a scattering object. We show that the position of a coronavirus-like 100 nm polystyrene sphere can be measured optically with deeply subwavelength accuracy.

Investigations on Diamond-NV-Centers as Alternative Labels in STED Microscopy [PDF]

EPJ Web of Conferences
We investigate diamond nitrogen-vacancy (NV) centers as alternative labels in stimulated emission depletion (STED) microscopy. To this end, artificial diamond is used as a substrate and Raman spectroscopy in photoluminescence (PL) mode is performed for ...

Analytical method for parameterizing the random profile components of nanosurfaces imaged by atomic force microscopy

, 2010
The functional properties of many technological surfaces in biotechnology, electronics, and mechanical engineering depend to a large degree on the individual features of their nanoscale surface texture, which in turn are a function of the surface ...

Analytical and Electrochemical Characterization of Mechanochemically Recovered Graphite from Spent Lithium‐Ion Batteries for Anode Additive Applications

Advanced Sustainable Systems, Volume 10, Issue 2, February 2026.
We introduce a new, energy efficient chemical treatment to recover graphite from Li‐ion battery waste. The graphite recovered this way can be re‐introduced in shares up to 50% in new anodes without neither capacity loss nor increased aging effects compared to “fresh” graphite.

Flicker Noise in Bilayer Graphene Transistors

, 2008
We present the results of the experimental investigation of the low - frequency noise in bilayer graphene transistors. The back - gated devices were fabricated using the electron beam lithography and evaporation.

True 3D Nanometrology: 3D-Probing with a Cantilever-Based Sensor

Italian National Conference on Sensors, 2021
State of the art three-dimensional atomic force microscopes (3D-AFM) cannot measure three spatial dimensions separately from each other. A 3D-AFM-head with true 3D-probing capabilities is presented in this paper. It detects the so-called 3D-Nanoprobes CD-

Origin of the Magnetization Anisotropy of Superparamagnetic Beads

Small, Volume 22, Issue 9, 12 February 2026.
Superparamagnetic beads are widely employed to study the mechanics of biomolecules with magnetic tweezers. It is shown that the residual anisotropy of the beads is due to averaging over a finite number of randomly oriented nanoparticles contained in the beads. Pinning of the anisotropic beads in the field causes low and high‐frequency noise in magnetic

Fabrication and Characterization of Topological Insulator Bi$_2$Se$_3$ Nanocrystals

, 2011
In the recently discovered class of materials known as topological insulators, the presence of strong spin-orbit coupling causes certain topological invariants in the bulk to differ from their values in vacuum.

Impact of substrate curvature on grazing‐incidence small‐angle X‐ray scattering signal: theory and example of Ag thin‐film growth

Journal of Applied Crystallography, Volume 59, Issue 1, Page 93-107, February 2026.
The paper formally addresses the influence of the substrate curvature and size on the grazing‐incidence small‐angle X‐ray scattering (GISAXS) signal. Using the established theory, GISAXS can be combined with substrate‐curvature‐based stress measurements, which is demonstrated on the example of Ag thin‐film growth.Grazing‐incidence small‐angle X‐ray ...
