Precipitation of niobic acid from potassium niobate in sulphuric acid solution: A route to niobium oxide

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4419-4434, August 2026.
Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5).

New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

Journal of Applied Toxicology, Volume 46, Issue 8, Page 2884-2894, August 2026.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, Volume 104, Issue 5, Page 498-509, August 2026.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Alteration of a Mantle‐Derived Dunite Boulder in Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract In 2023, the Mars 2020 Perseverance rover explored the youngest preserved deposits on the Western fan of Jezero crater, Mars: a field of meter‐scale boulders dispersed above the previously explored sandstone and siltstone units. Reflectance spectra of the boulders delineated two classes, one olivine‐bearing and one pyroxene‐bearing.

Contrast Agents for Enhanced Bioimaging: A Comprehensive Review

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Contrast agents, especially those that are nanoparticle‐based, are revolutionizing bioimaging by enabling highly sensitive, specific, and early‐stage diagnosis of diseases like cancer, using clinical imaging modalities such as CT, MRI, PET, and SPECT.
