On Refinement of Several Physical Notions and Solution of the Problem of Fluids for Supercritical States [PDF]

open access: yesarXiv, 2009
To solve the ancient problem of fluids, i.e., of states in which there is no difference between gas and liquid (the so-called supercritical states), it is necessary to abandon several "rules of the game", which are customary to physicists and to refine them by using rigorous mathematical theorems.

Pre‐treatment with extraction solvent yields higher recovery: Method optimization for efficient determination of polycyclic aromatic hydrocarbons in organic‐rich fine‐textured wastes

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Fluid fine tailings (FFT) contain numerous organic compounds, including polycyclic aromatic hydrocarbons (PAHs). Growing concerns of PAH toxicity warrants monitoring for environmental consequences and natural attenuation. Conventional Soxhlet extraction yields low (∼50%–60%) recovery of PAHs (naphthalene, phenanthrene, pyrene, dibenzofuran ...

Subcritical Fluid Chromatography at Sub-Ambient Temperatures for the Chiral Resolution of Ketamine Metabolites with Rapid-Onset Antidepressant Effects

open access: yesMolecules, 2019
Chiral metabolites of ketamine exerting rapid-onset yet sustained antidepressant effects may be marketed directly in the future, but require chemo- and enantio-selective chromatographic methods for quality assurance and control.

Comments on Van der Waals supercritical fluid: Exact formulas for special lines [J. Chem. Phys. 135, 084503 (2011)] [PDF]

open access: yesarXiv, 2018
The equations for Widom lines for the supercritical van der Waals fluid were considered in the paper J. Chem. Phys. 135, 084503 (2011). But the equations for the speed of sound and its special Widom line were incorrect. The correct equations are obtained.

Synthesis of Poly (2‐hydroxyethyl ethyleneimine) and Its Mucoadhesive Film Formulations When Blended with Chitosan for Buccal Delivery of Haloperidol

open access: yesMacromolecular Bioscience, EarlyView.
Mucoadhesive chitosan‐poly(2‐hydroxyethyl ethyleneimine) (P2HEEI) films were developed for buccal delivery of haloperidol. P2HEEI is synthesized by reacting linear polyethyleneimine with 2‐bromoethanol, achieving high solubility, low glass transition temperature, and biocompatibility.
