Shape Analysis and Recognition Method of Artworks Based on Computational Geometry

open access: yesEngineering Reports, Volume 8, Issue 8, August 2026.
Traditional methods for shape analysis and recognition of artworks have many shortcomings in terms of precision, efficiency, and complex shape processing. Especially when faced with complex or abstract artworks, it is often difficult to provide accurate classification and recognition results.

Salinity, turbidity, and chlorophyll drive zooplankton succession in a temperate estuary under anthropogenic pressure

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Estuarine zooplankton are vital primary consumers and essential for estuarine ecosystem functioning and productivity, but they face strong physico‐biochemical gradients and often anthropogenically altered habitats that impact their succession.

Laser‐Based In Situ Diagnostics of Temperature and Material‐Growth Dynamics in Photothermal Laser Nanoprinting of ZnO

open access: yesLaser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
This work elucidates the previously unknown thermal dynamics during sub‐micrometer photothermal laser printing of zinc oxide using a non‐invasive transmission‐based in situ measurement. The elevated temperatures are shown to be highly localized around the laser focal spot, reaching average temperature increases of about 113 K per mW of laser power ...

Accurate Sizing and Resolution of Nominal 200 nm Diameter Polystyrene Nanospheres With Charge Detection Mass Spectrometry

open access: yesSmall, Volume 22, Issue 43, 3 August 2026.
This study highlights the utility of charge detection mass spectrometry (CDMS) as a high‐throughput nanoparticle characterization tool. CDMS measurements of 200 nm polystyrene size standards are within 1% of those derived from transmission electron microscopy (TEM). Notably, a mixture of three ∼200 nm samples is readily resolved by CDMS but not by TEM,

Dislocation Bands and Subboundaries in Experimentally Deformed Olivine

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Transmission electron microscopy imaging of dislocations in olivine indicates heterogeneous structures and diversity of dislocation types. However, the volumes imaged at high resolution are smaller than individual grains even of fine‐grained samples.
