Aqueous solubility and permeability through biomembranes are important parameters for drug bioavailability. Nanoparticles can be considered as a useful tool for improving properties of poorly soluble and/or permeable active ingredients. Hydrochlorothiazide (Class IV of BCS) was chosen as a model compound. Antisolvent precipitation – solvent evaporation and emulsion solvent evaporation methods w...
The solubility of acid soluble soy protein (ASSP) is poor in the pH range of 4-7. ASSP-dextran conjugates were prepared through the Maillard reaction to increase the solubility and/or dispersibility of ASSP. By using the conjugates and ultrasonication emulsification, stable oil-in-water emulsions with submicrometer-sized droplets were obtained. The factors, such as ASSP conjugation degree, that...
Organic–inorganic perovskites have an impressive potential for the design of next generation solar cells and are currently considered upscaling commercialization. Currently, perovskite rely on spin-coating which is neither practical large areas nor environmentally friendly. Indeed, one conventional most effective lab-scale methods to induce crystallization, antisolvent method, requires amount t...
Kobayashi, N; Procop, GW; Fujishiro, T; Tuohy, MJ; +Bauer, TW +The Cleveland Clinic Foundation, Cleveland OH [email protected] Introduction The importance of bacterial biofilm associated with joint implants has been recognized widely and investigated. These bacteria are best detected after the biofilm has been disrupted by, for example, ultrasonication. Although ultrasonication enhances detect...
A new preparative route for vanadium phosphate catalysts is described using supercritical CO2 as an antisolvent. The amorphous microspheroidal VPO produced is shown to be more active than comparable crystalline VPO catalysts for the selective oxidation of n-butane to maleic anhydride and, furthermore, does not require an extensive pre-treatment or activation period to establish full catalytic a...
