Past winners include Gardens for Health, an organization that improves the nutrition, health and treatment of people living with HIV/AIDS through sustainable agriculture, and SolarCycle, which produces sustainable, durable and affordable solar cookers and water pasteurizers using a material made of used plastic bags and the aluminized insides of potato chip bags.
I.B.M. is developing another chip that achieves the same goal more elegantly, using a material that changes phase from amorphous to crystalline with a certain degree of randomness.
It treats urine and faeces separately, using a material freely available in many of the world's poorest regions: sand.
Conversely, using a material with properties that go well beyond the reliability requirements adds unnecessary cost.
This work also examines the fracture toughness trends using a material failure criterion for crack growth.
He also claimed qualified immunity, on the grounds that there was no established constitutional violation for using a material arrest warrant at the time of the arrest.
"This project allowed my class to design something of their choice, using a material of their choice and raise environmental awareness at the same time".
The isolation performance could therefore have been improved by using a material with a lower Young's modulus.
For many, if not most, consumers, it is the symbolism of a new handbag or new car, its expensive logo proudly displayed, that delivers happiness, rather than twenty years of using a material object.
The change in weight from method (1) agreed well with results from (2) using a material balance.
The numerical simulation was carried out using a material point method followed by a bookkeeping operation to regrid the film.
