1. Aluminum-based syntactic foams are finding applications in the automotive sector. 2. The compressive properties of syntactic foams , in most cases, strongly depend on the properties of microballoons. 3. Gupta worked on the use of fly ash hollow particles ( cenospheres ) in creating syntactic foams . 4. Such composite materials are called syntactic foam . 5. The Fevernova's innovation is its inner layer of syntactic foam commonly used in insulation and flotation devices. 6. Gupta developed a new functionally graded syntactic foam material and a method to create multifunctional syntactic foams. 7. Gupta developed a new functionally graded syntactic foam material and a method to create multifunctional syntactic foams . 8. Buoyancy is provided by syntactic foam . 9. A special class of closed-cell foams, known as syntactic foam , contains hollow particles embedded in a matrix material. 10. His team has also created an ultralight magnesium alloy syntactic foam that is able to float on water.
