New truck oil pan made of DuPont™ Zytel® polyamide resin, injection moulded by ElringKlinger for Mercedes-Benz, is up to 6 kgs (50 percent) lighter than aluminium, can resist stone and gravel chip impact during the typical 1.5 million kilometre lifetime of a truck or bus engine, and integrates functions not possible with metal.
These technologies will be featured on the DuPont Stand C43, Hall 06, at K 2013, Düsseldorf, Germany, October 16-23, 2013.
Lightweighting has been identified by the auto industry as a critical way to improve fuel efficiency and reduce CO2 emissions. DuPont is collaborating with industry to develop lighter weight components that meet performance requirements by designing first for inherently lightweight plastics.
“Designing for plastic rather than using plastic in a component designed for metals requires a different approach and material data, but helps ensure all the lightweighting, strength and functional benefits are captured,” said Patrick Cazuc, automotive director EMEA, DuPont Performance Polymers. To support this, DuPont is characterizing its materials in more dynamic situations.
“Testing we have done with the industry shows that we are able to better predict performance, helping to improve the material selection process and speed the development time.”It has been estimated that reducing an automobile’s total weight by just 50kg can reduce CO2 emissions by up to 5g/km, and increase fuel economy by up to 2 percent. In engines alone, replacing metal with plastic in known engine applications can eliminate at least 11 kgs per vehicle, and double the life of parts exposed to high heat in turbo charged engines. Apply that to the 83 million engines scheduled for 2013, and the need for over 1 billion litres of fuel, or almost 10 million barrels of crude oil, can be eliminated.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
