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.

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.
