Development of Meso-scale Simulator for Polymeric Materials

Meso-scale Flight and Miniature Rotorcraft Development

This paper summarizes the initial development of a very small-scale rotorcraft that flies on its own power and carries sensors for atmospheric research or planetary exploration. Initial devices are electrically powered, ranging in size from 2 to 15 cm, and have involved challenges in aerodynamics, control, and manufacturing. Many interesting scaling issues arise as one shrinks a flight vehicle ...

Development of Nanocomposite Reinforced Polymeric Materials to be Used for Racks for Retorting Polymeric Trays

Language Learning Materials Development for Teachers’ Professional Development

Coursebooks are normally written to contain information, instruction, exposure, and activities that learn- ers at a particular level need to enhance their communicative competence in the target language. Howev- er, many global course books make attempts to include content, topics, and texts that do not disadvantage any learner around the world. That is why global course books normally do ...

Polymeric triple-shape materials.

Shape-memory polymers represent a promising class of materials that can move from one shape to another in response to a stimulus such as heat. Thus far, these systems are dual-shape materials. Here, we report a triple-shape polymer able to change from a first shape (A) to a second shape (B) and from there to a third shape (C). Shapes B and C are recalled by subsequent temperature increases. Whe...
