Taftan Pozzolan-Based Geopolymer Cement
Abstract: In recent years, many research works have been done to investigate the possibility of utilizing a broad range of materials as raw materials in the production of geopolymer cements. The use of artificial pozzolans or aluminosilicate-type industrial waste materials such as granulated blast-furnace slag and fly ash has been reported in many research works. Natural pozzolans are also al...
متن کاملDry Powder Inhalers: A Review
In the recent years pulmonary drug delivery system is found to be preferred route of administration for various drugs. It has been divided into 3 classes: Nebulizers, pMDI, DPI.DPI are used as an alternative to pMDI because pMDI contains propellant (CFC) which has ozone depletion characteristics. DPI delivers medication in the form of dry powder to lungs. DPI is formulated either as a carrier b...
متن کاملRheology of Geopolymer: Comparative Study between Portland Cement and Metakaolin Based Geopolymer
Metakaolin based geopolymers are presented in many studies as an alternative to normal Portland cement. Previous studies have focused on their chemical and mechanical properties, their microstructures and their potential uses, but very few on their rheological behaviour. Our work highlights the main differences that exist between geopolymer and Portland cement. These materials behave as Newtoni...
متن کاملAssessing dry powder inhalers
To enable what would otherwise be impractical, invasive and potentially dangerous testing, and to remove the huge variation and costs associated with human subjects, it is common practice to test inhalation devices and formulations using in vitro test apparatus. Industry standard test conditions and relevant parameters have been devised and published by the regulatory authorities and within the...
متن کاملDry powder inhaler formulation.
A drug product combines pharmacologic activity with pharmaceutical properties. Desirable performance characteristics are physical and chemical stability, ease of processing, accurate and reproducible delivery to the target organ, and availability at the site of action. For the dry powder inhaler (DPI), these goals can be met with a suitable powder formulation, an efficient metering system, and ...
