Novel Synthesis of Encapsulated Super Paramagnetic Iron Nanoparticles (Fe3O4) and its Evaluation in Drug Delivery System
Abstract: Nanoparticles can be defined as solid, submicron, colloidal particles ranging in size from 10–100 nm in diameter, generally but not necessarily made of natural or synthetic polymers, in which drugs can be adsorbed, entrapped, that exhibit new or enhanced size-dependent properties as compared to microparticles. Iron oxide nanoparticles are often magnetic by nature, which means that they obey Coulomb’s law, and can be manipulated by an external magnetic field gradient. …

The MEA Evolution in Commercial Aircraft and the Consequences for Initial Aircraft Design
Abstract: An important objective in commercial aircraft design is to develop a ’greener’ aircraft. This objective poses many challenges in many fields of aircraft design. The push towards a more environment friendly, efficient and cost effective design has recognized the ‘MEA (more-electric aircraft)’ as a means to contribute towards realizing this goal. The more-electric aircraft can be thought of as an evolutionary concept where non-electrically powered systems and components are gradually …
