Herein we report preparation of polymeric monofunctional nanoparticles (PMNs) through intramolecularly cross-linking the polymer chains sparsely grafted on the surface of sacrificial silica spheres, and a one-to-one coupling reaction between PMNs and linear polymer chains and that between two PMNs.
In this article various pipes used for transporting of gas are introduced and pros and cons of each one are elucidated. The pipes are categorized in three different subgroups including metallic, polymeric and metallic-wire reinforced polymeric pipes. Metallic-wire reinforced polymeric pipes are nominated as the best option for usage in high pressure pipelines transporting natural gas. As a resu...
Urethan, a potent teratogenic and carcinogenic agent in experimental animals, has been used in Japan for the past 25 years as a cosolvent of water-insoluble analgesic and sedative drugs. Urethan is used also as a solubilizer and cosolvent for pesticides, fumigants, and cosmetics, because it is a good solvent for various organic materials (6). In the past, urethan was used clinically as an antin...
A thermally stable, piezoelectric and pyroelectric polymeric substrate was prepared. This thermally stable, piezoelectric and pyroelectric polymeric substrate may be used to prepare electromechanical transducers, thermomechanical transducers, accelerometers, acoustic sensors, infrared sensors, pressure sensors, vibration sensors, impact sensors, in-situ temperature sensors, in-situ stresshtrain...
poor skin penetration. To improve the cutaneous absorption of drugs, various methods have been developed such as chemical penetration enhancers, novel vehicle systems and physical enhancement techniques including iontophoresis, sonophoresis, and electroporation. Supersaturated formulations are one of the vehicle systems, and its potential benefit has been examined by many investigators. Supersa...
