in order to improve local therapeutic techniques for the massively burnt patients and to minimize the pain associated with dressing change, the concept of topical film was utilized to formulate a topical antimicrobial spray. the commonly used topical antimicrobial silver sulfadiazine spray was formulated as a new drug delivery system. the release of therapeutic agents in vitro from medicated sp...

There are many ways to reduce diesel engine exhaust emissions. However, NOx emission is difficult to reduce because the hydrocarbon (HC) concentration in a diesel engine is not sufficient for NOx conversion. Therefore, in order to create stoichiometric conditions in the De-NOx catalyst, a secondary injection system is designed to inject liquid HC into the exhaust pipe. The atomization and distr...

The aim of this work is to describe and characterize a new spray-drying procedure for the production of nasal powders as an alternative to the conventional freeze-drying method. Cyanocobalamin was chosen as the active ingredient and loaded into five different nonsoluble vehicles with high water absorption ability. Then these hydrated particles were suspended in methylene chloride and spray-drie...

We report on cost-effective ITO-free organic solar cells (OSCs) fabricated by a spray deposition method. All solution-processable layers of solar cells—a highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) layer and a photoactive layer based on poly(3-hexylthiophene) (P3HT) and 1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C61 (PCBM)—were spray-coated. PEDOT:PSS a...

Paper spray mass spectrometry is a method for the direct analysis of biofluid samples in which extraction of analytes from dried biofluid spots and electrospray ionization occur from the paper on which the dried sample is stored. We examined matrix effects in the analysis of small molecule drugs from urine, plasma, and whole blood. The general method was to spike stable isotope labeled analogs ...

the first aim of the present investigation was to prepare solid dispersions to improve the dissolution properties of oxcarbazepine and quetiapine using peg 6000 as a carrier with the help of two methods of preparations viz. spray drying and modified solvent method, and to compare the two methods. the second objective was to apply the modified solvent method for preparation of sustained release ...

OBJECTIVE To use a non-invasive measurement of oxygen saturation in chronic leg ulcers after the application of a topical haemoglobin spray to investigate if photoacoustic tomography is able to measure the oxygen saturation and if the stimulated oxygen increase can be demonstrated. METHOD We measured the oxygen saturation of the ulcer tissue in five patients with chronic leg ulcers before app...

OBJECTIVE To evaluate the efficacy of using a nicotine patch for 5 months with a nicotine nasal spray for 1 year. DESIGN Placebo controlled, double blind trial. SETTING Reykjavik health centre. SUBJECTS 237 smokers aged 22-66 years living in or around Reykjavik. INTERVENTIONS Nicotine patch for 5 months with nicotine nasal spray for 1 year (n=118) or nicotine patch with placebo spray (n...

A fully automatic spray-LBL machine with monitoring the real time growth of multilayer films using Quartz Crystal Microbalance (QCM) techniques was newly developed. We established fully automatic spray layer-by-layer method by precisely controlling air pressure, solution flow, and spray pattern. The movement pattern towards the substrate during solution spraying allowed fabrication of a nano-sc...
