Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3775-3795, July 2026.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

Struvite Production From Wastewater: Effect of Magnesium‐to‐Ammonia Ratio and Stirring Velocity on Precipitation Efficiency and Settling Behavior

open access: yesCLEAN – Soil, Air, Water, Volume 54, Issue 7, July 2026.
This study demonstrates that stoichiometric Mg2+:PO43− excess (1.1:1) and slow 10‐min dosing are critical for maintaining low supersaturation, yielding large crystals (>0.84 mm) and rapid settling (5.5–10.1 cm/min). This strategy optimizes nutrient recovery (≥80%) and solid–liquid separation without flocculants, proving viable for complex industrial ...

Registered Clinical Trials of Ayahuasca and DMT: A Scoping Review

open access: yesClinical Pharmacology &Therapeutics, Volume 120, Issue 1, Page 94-108, July 2026.
Interest in ayahuasca and its main component, N,N‐Dimethyltryptamine (DMT), has currently moved from historical and experimental use into modern clinical development. Yet, current evidence is fragmented, and systematic mapping of trial methods and design choices remains limited.

A Comparison of Realized Measures of Integrated Volatility: Price Duration‐ vs. Return‐Based Approaches

open access: yesJournal of Forecasting, Volume 45, Issue 4, Page 1579-1600, July 2026.
ABSTRACT We study the accuracy of a variety of parametric price duration‐based realized variance estimators constructed via various financial duration models and compare their forecasting performance with the performance of various nonparametric return‐based realized variance estimators.

Thermal, Structural, and Molecular Characterization of a Model Cereal–Milk Infant Formula: Impact of Ultrasound Pre‐Treatment Prior to Spray Drying

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
This study evaluated the efficacy of an ultrasound pre‐treatment applied to a complex cereal–milk infant formula prior to conventional spray drying to mitigate inherent stickiness and yield challenges. Acoustic cavitation (30–90 s) significantly reduced suspension viscosity and improved atomization efficiency, elevating powder recovery yield from 12 ...
