TL;DR: In this article, the physical and optical properties of titanium dioxide particulate suspensions in water were investigated for six different commercially available powders, including size of elementary particles, size of particle aggregates in water suspensions, specific surface area, and spectral extin...

TL;DR: In this paper, a kinetic model to represent the time evolution of a photocatalytic reaction is presented, which can be applied for reacting systems having the following characteristics: (i) the catalyst is a suspension (in water) of fine particles of titanium dioxide, (ii) the substrate is a hydrocarbon compound amenable to hydroxyl radical attack for the initiation of an oxidative reaction, (iii) the activation is produced by radiation energy in the near ultraviolet range (300 nm ≤ λ ≤ 400 nm), and (iv) oxygen is always present in the reacting medium

TL;DR: In this paper, a new approach for modeling the drug release from planar polymeric systems containing slowly dissolving drugs is presented, which explicitly avoids solving multiple mass balances for the interwoven regions of solid and dissolved drugs, and makes easier the numerical solution.

TL;DR: The intrinsic reaction kinetics of trichloroethylene in water employing suspended titanium dioxide catalytic particles have been studied using near ultraviolet polychromatic radiation as mentioned in this paper, and the results were analyzed in terms of a reaction model previously developed in Part I.

TL;DR: A mathematical modeling of controlled release of drug from torus-shaped single-layer devices is presented and a good agreement between the model prediction and the experimental data is observed.
