Current Trends on Solid Dispersions: Past, Present, and Future

open access: yesAdvances in pharmacological and pharmaceutical sciences, 2022
Solid dispersions have achieved significant interest as an effective means of enhancing the dissolution rate and thus the bioavailability of a range of weakly water-soluble drugs.

Dispersion measures and dispersive orderings [PDF]

open access: yesStatistics & Probability Letters, 2003
In this paper, the comparison of random variables according to the functionals of a general class of dispersion measures is characterized in terms of the dilation order. The Gini's mean difference is a particular member of this general class. In addition, a new and weaker order, called the second-order absolute Lorenz ordering, is introduced, and we ...

Dispersive stabilization [PDF]

open access: yesBulletin of the London Mathematical Society, 2010
Ill posed linear and nonlinear initial value problems may be stabilized, that it converted to to well posed initial value problems, by the addition of purely nonscalar linear dispersive terms. This is a stability analog of the Turing instability. This idea applies to systems of quasilinear Schrödinger equations from nonlinear optics.

Advances in Waterborne Polyurethane and Polyurethane-Urea Dispersions and Their Eco-friendly Derivatives: A Review

open access: yesPolymers, 2021
Polyurethanes and polyurethane-ureas, particularly their water-based dispersions, have gained relevance as an extremely versatile area based on environmentally friendly approaches. The evolution of their synthesis methods, and the nature of the reactants

Price Dispersion [PDF]

open access: yesSSRN Electronic Journal, 2003
We model firm pricing given consumers follow simple reservation price rules. Such reservation rules are rational when consumers are sufficiently impatient. The equilibrium exhibits price dispersion in pure strategies, with lower price firms earning higher profits.

The combination of hydroxypropylmethylcellulose acetate succinate and L-lysine into ternary amorphous solid dispersions of quercetin to enhance its dissolution

open access: yesCarbohydrate Polymer Technologies and Applications, 2021
The purpose of this study was to enhance quercetin (Que) dissolution by preparing its ternary amorphous solid dispersions. The ternary amorphous solid dispersions were prepared by solvent evaporation method using hydroxypropylmethylcellulose acetate ...

Get Beyond Limits: From Colloidal Tectonics Concept to the Engineering of Eco-Friendly Catalytic Systems

open access: yesFrontiers in Chemistry, 2018
The interactions between two or more molecules or colloidal particles can be used to obtain a variety of self-assembled systems called supramolecules or supracolloids. There is a clear, but neglected, convergence between these two fields.

The Dispersion Bias

open access: yesSSRN Electronic Journal, 2017
Estimation error has plagued quantitative finance since Harry Markowitz launched modern portfolio theory in 1952. Using random matrix theory, we characterize a source of bias in the sample eigenvectors of financial covariance matrices. Unchecked, the bias distorts weights of minimum variance portfolios and leads to risk forecasts that are severely ...

Preparation of aqueous dispersion of thermoplastic sizing agent for carbon fiber by emulsion/solvent evaporation [PDF]

open access: yes, 2013
In this work, different sizing agent aqueous dispersions based on polyetherimide (PEI) were elaborated in order to improve the interface between carbon fibers and a thermoplastic matrix (PEEK).
