Nonconventional Techniques in Plant Alkaloid Extraction: A Decade of Progress (2014–2023)
Chemistry &Biodiversity, EarlyView.This figure seeks to represent the evolution of the different unconventional approaches that were adopted for the extraction of plant‐derived alkaloids during the decade from 2014 to 2023. ABSTRACT Plant metabolism encompasses primary and secondary pathways, with secondary metabolism yielding diverse natural products crucial for plant adaptation and ...

ChemCatChem, EarlyView.Exfoliation by ultrasound of graphitic carbon nitride improved activity for the photoreduction of CO2. Abstract Exfoliation of graphitic carbon nitride g‐C3N4 by means of ultrasound (US) treatment at varying input power is investigated. Exfoliation of g‐C3N4 displays a strong dependence of US input power, with a slightly enhanced bandgap (2.8 eV), but ...

Practicum Students’ Anticipatory Thoughts About Challenging Client Situations
Counselor Education and Supervision, EarlyView.ABSTRACT Practicum students’ anxiety as they envision seeing “real” clients can impede their self‐efficacy and in‐session functioning. To explore how anticipatory stress and coping theory might help better support them, we used CQR‐M to code students’ (n = 42) immediate thoughts and reactions to three challenging client situations before and after ...

Canadian Journal of Administrative Sciences / Revue Canadienne des Sciences de l'Administration, EarlyView.ABSTRACT Research suggests employees are more productive when they feel their supervisor trusts them. However, the underlying processes that explain this relation are not well understood. We investigated whether self‐determination (a motivational construct) mediates the relation between felt trust and task performance.

Local sensitivity analysis of a supercritical extraction model
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study investigates the process of chamomile oil extraction from chamomile flowers. A parameter‐distributed model, consisting of a set of partial differential equations, was used to describe the governing mass transfer phenomena between solid and fluid phases under supercritical conditions using carbon dioxide as the solvent.

ChemPhysChem, EarlyView.Recent advancements in surface plasmon resonance protocols and simulations have enhanced the measurement and prediction of diffusion coefficients (D) for chemical species in microfluidic channels. These developments enable precise determination of D values for molecules ranging from a few angstroms to nanometric aggregates, facilitating detailed ...
