Car parts and ketchup share their behaviour
A new process for die-casting copper car components is just like pouring ketchup, says Dr. Helen Atkinson of the University of Sheffield, UK, speaking at the British Association Festival of Science.

Spray Forming Aerospace Alloys For Bigger Aircraft
Spray forming technology is rapidly becoming one of the most cost-effective and reliable ways of producing aircraft engine parts from nickel and aluminium superalloys. The technology uses tiny atomised droplets of metallic alloys to produce components that in many cases are stronger and tougher than traditionally produced parts. The process allows the construction of large components which could ultimately result in larger engines and larger aircraft. (1999-06-02)

Superplasticity May Work Better In Smaller Packages
A physical quality called superplasticity lets manufacturers fashion metal into strong, intricate shapes, such as turbine blades and aircraft components. But achieving superplasticity typically requires impractically long cooking times or high heats. Now researchers at the University of California, Davis, report findings that could simplify that process. (1999-04-21)

For First Time In 40 Years National Jewish Researchers Report Chronic Beryllium Disease Caused By Extremely Low Levels Of Exposure
Exposure to extremely low levels of a lightweight metal commonly used to make everything from nuclear weapons to golf clubs has been shown to cause chronic beryllium disease (CBD) in workers who manufacture these products, according to National Jewish Medical and Research Center physicians. (1999-04-19)

True Grit: "Sandpaper" Alloy May Suggest Rugged, Powerful New Devices, UD Researcher Reports
Sandpaper's cousin, silicon-carbide, may set the stage for a rugged, powerful new breed of semiconducting devices, a University of Delaware researcher will report April 6 during the Materials Research Society meeting. A new alloy of silicon-carbide and germanium might handle hot, high-power, high-frequency microelectronic and microelectromechanical (MEMS) devices better than silicon, James Kolodzey says. (1999-04-07)

The Universal Multi-Zone Crystallizator is a precision furnace from Hungary which may finally get a chance to fly due to collaboration between scientists at NASA and Hungarian Universities. (1999-03-22)

The Side Effects Of Dental Amalgam May Be All In The Mind
Health campaigners have for years blamed amalgam fillings, containing mercury, for a host of neurological disorders including Alzheimer's disease. Now a new German study suggests that many people who complain about the side effects of amalgam fillings are unwittingly using it as a scapegoat for disorders that have other causes. (1999-02-03)

Modeling Material Defects From Atoms Up
A $1.5 million, three-year NSF grant to the Cornell Theory Center will support a project in Multiscale Modeling of Defects in Solids, to enable computer simulations at scales ranging from the atomic level to the macroscopic to communicate with one another and show how defects at the atomic level can lead to the visible cracks we can see and measure in the everyday world. The work has applications in materials ranging from aircraft skins to computer chips. (1998-10-18)
