Substituent‐Dependent Structural Trends in Thermal Condensation of Silanetriols and Disiloxanetetraols

open access: yesChemistry – A European Journal, EarlyView.
We report a catalyst‐ and solvent‐free thermal condensation route to oligosilsesquioxanes from arylsilanetriols and disiloxanetetraols. Phenyl and 1‐naphthyl systems form ladder‐like structures, while 2‐naphthyl systems yields layered architectures.

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

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
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). Thermodynamic modelling with PHREEQC and

Clathrate hydrate crystallization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

Tuning the Growth Pattern of Triangular Silver Nanoplates from Lateral to Vertical by Secondary Metal Addition

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
What happens, if in the synthesis of flat silver platelets, the slow deposition of silver along twinning faults is disturbed by the addition of a nobler metal? We have looked into it and found a way to fine‐tune the metal deposition in lateral and vertical direction.

Nodular Fasciitis of the Parotid Gland Mimicking Pleomorphic Adenoma: Cytological Features of a Diagnostic Pitfall

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Nodular fasciitis (NF) is a self‐limiting mesenchymal neoplasm that typically occurs in the subcutaneous tissue of the extremities, trunk, and head and neck region; involvement of the parotid gland is very rare. The cytological features of NF can closely mimic those seen in salivary gland neoplasms, particularly pleomorphic adenoma (PA ...
