The objective of this study was to evaluate the possibilities to control the release rate of dexmedetomidine (DMED) from different spray-dried silica gel microparticle formulations. Microparticles were prepared by spray drying a silica sol polymer solution containing the drug. Drug release was investigated both in vitro and in vivo.

A Gellan-Based Fluid Gel Carrier to Enhance Topical Spray Delivery
Acta Biomaterialia, 2019Autologous cell transplantation was introduced to clinical practice nearly four decades ago to enhance burn wound re-epithelialisation. Autologous cultured or uncultured cells are often delivered to the surface in saline-like suspensions. This delivery method is limited because droplets of the sprayed suspension form upon deposition and run across the ...

The objective of this study was to evaluate sol-gel-derived spray dried silica gel microspheres as carrier material for dexmedetomidine HCl and toremifene citrate. The drug was dissolved in sol-gel processed silica sol before spray drying with Büchi laboratory scale equipment. Microspheres with a low specific surface area were spherical by shape with a

A Graphical Spray Analysis Method for Gel Spray Characterization
46th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2010This paper presents the results of a set of impinging jet gel spray experiments and the tools used to analyze the results. The use of gelled propellants in combustion chambers has offered storage and safety benefits, but the spray characteristics of non-Newtonian fluids at high shear rates is poorly understood.

Gel-processed powders for plasma spraying
Thin Solid Films, 1982Abstract The scope of sol-gel methods for preparing plasma spray powders has been extended by developing a technique in which small amounts of aqueous sols are made to carry particulate material and then gelled and fired to yield free-flowing spherical particles.

Stimuli-Responsive in situ Spray Gel of Miconazole Nitrate for Vaginal Candidiasis
Journal of Pharmaceutical Sciences, 2023Vaginal candidiasis is a common form of infection in women caused by Candida species. Due to several drawbacks of conventional treatments, the current research is attempted to formulate and optimize a miconazole nitrate-loaded in situ spray gel for vaginal candidiasis.

Experimental Characterization of a Pulsatile Injection Gel Spray
41st AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2005The atomization of plain and gelled (non-Newtonian) water using pulsatile injection was investigated. Periodic disturbances were introduced to the atomized jet and their influence on the spray character was studied. A simple triplet air-blast atomizer was utilized.

Thermoresponsive Ozone-Enriched Spray Gel for Postsurgical Treatment of Hepatocellular Carcinoma
ACS Nano, 2023Surgical resection of hepatocellular carcinoma suffers from a high recurrence rate. Ozone directly kills tumor cells by generating reactive oxygen species in vitro, but its high reactivity and short half-life severely limit its tumor accumulation and penetration for the treatment of tumors in vivo. Herein, a thermoresponsive ozone-enriched spray gel is

Spray characteristics of aluminized-gel fuels sprayed using pressure-swirl atomizer
Journal of Non-Newtonian Fluid Mechanics, 2017Abstract A slurry fuel is a non-Newtonian shear-thinning fluid with high viscosity. The fuel has a high energy density and has advantages in feed control. When the slurry fuel is injected using a swirl atomizer, the spray characteristics change because the rheological characteristics are different from those of the conventional liquid fuel.

Organic Gel Spray Diffusion Flames-An Improved Model
46th AIAA Aerospace Sciences Meeting and Exhibit, 2008An improved model of a co-flow Burke-Schumann type of diffusion flame fueled by a spray of organic gel fuel droplets is presented. The model incorporates the phenomenological oscillatory evaporation and burning of such droplets and assigns a temperature dependence to the frequency of the oscillations.
