Cleaner coating metal food can

Cleaner coatings for food cans

Exploring cleaner coatings for metal cans to inhibit chemical migration into food.

Laser welding of dissimilar materials

Using a novel joint design, laser welding of dissimilar materials can be transformed, according to scientists at The Welding Institute (TWI), Cambridge, UK. This could improve the quality of lightweight magnesium and aluminium alloy components used in the automotive sector.

Plastic laser one step closer

Polymer lasers could be one step closer to reality thanks to research conducted at the University of California at Los Angeles, USA, using a luminescent semiconducting polymer. Such devices offer potential for brighter and cheaper polarised light sources.

Hydrogen storage at room temperature for fuel cells

Scientists at the University of Virginia, based in Charlottesville, USA, claim to have discovered a material, made from titanium atoms complexed with ethylene, that can store large quantities of hydrogen at room temperature. This could help in the search for a more efficient and affordable hydrogen-powered fuel cell.
