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 ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

Laser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Unlocking the Full Potential of Zinc Oxide/Cerium Oxide Composite Nanoparticles for Removal of Mixed Pharmaceutical and Dye Pollutants in Water

Advanced Materials Interfaces, Volume 13, Issue 8, 21 April 2026.
ZnO/CeO2 composite nanoparticles synthesized via a facile hydrothermal method simultaneously degrade ciprofloxacin, tetracycline, methylene blue, and methyl orange in a four‐component mixture under UV irradiation. The Ce3+/Ce4+ redox cycling and oxygen vacancies at the ZnO/CeO2 interface suppress charge recombination and enhance reactive species ...

Mueller Matrix Ellipsometric Approach on the Imaging of Sub-Wavelength Nanostructures

Frontiers in Physics, 2022
Conventional spectroscopic ellipsometry is a powerful tool in optical metrology. However, when it comes to the characterization of non-periodic nanostructures or structured fields that are much smaller than the illumination spot size, it is not well ...

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.

Effect of nanoparticle morphologies on signal strength in photoacoustic sensing [PDF]

, 2017
Spherical gold nanoparticles with a plasmonic extinction peak at 532 nm and two sizes of star shaped gold nanoparticles with plasmonic extinction peaks at 532 nm and 600 nm were synthesised and introduced into tissue phantoms as exogenous absorbers.

Fundamentals of Deep‐Subwavelength Near‐Field Imaging With Hyperbolic Polaritons

Nanophotonics, Volume 15, Issue 8, 24 April 2026.
Hyperbolic polaritons enable deep‐subwavelength near‐field imaging. This work reveals the intrinsic resolution limit of polaritonic imaging by linking it to the linewidth of hyperbolic polariton beams. A negative‐refraction‐based strategy is proposed to achieve scale fidelity under appropriate thickness configurations and to mitigate geometrical ...

Lanthanide‐Doped NaGdF4 Nanoparticles as Versatile Luminescent Labels for Cathodoluminescence Mapping

physica status solidi (b), Volume 263, Issue 4, April 2026.
This study presents a synthesis method for lanthanide‐doped NaGdF4 particles in an aqueous environment. Clearly distinct cathodoluminescence (CL) spectra were observed for europium‐ and thulium‐doped nanoparticles, stable for up to 100 s of excitation time.
