Metals merged into amalgam nanocrystals in new manufacturing method

A new, surprisingly simple method merges two metals into one nanocrystal structure. This could allow almost any two metals to be combined, creating brand new types of intermetallic nanocrystals that could be useful for a whole range of applications.

Waste-derived synthetic gypsum could replace the real thing

Composed of calcium sulfate dihydrate, gypsum is a naturally occurring mineral used in building materials. Scientists have now devised a method of creating synthetic gypsum, which should be more energy efficient than processing the genuine article.

World’s lightest sound insulator could radically reduce jet engine noise

This graphene-based aerogel is the lightest sound insulation material ever manufactured, say researchers at the University of Bath, who have demonstrated its ability to damp down noise by up to 16 dB despite weighing just 2.1 kg per cubic meter.

Recyclable “bioactive” paper bag could replace plastic food wrap

In most grocery stores, all of the fresh produce is either pre-wrapped in plastic film or it gets placed in plastic bags – both of which are often discarded by consumers. A new bioactive paper bag, however, could serve the same purpose while being easily recyclable.

Magnesium alloys claimed to lighten heat removal systems by one third

Both cars and electronic appliances require heat removal systems, typically made of steel or aluminum. That may soon change, though, as scientists have created two magnesium alloys which they claim can reduce the weight of such systems by a third.

Cartilage-inspired material may find use in self-lubricating bearings

As anyone with arthritis will know, cartilage plays a vital role in allowing our joints to move freely. Scientists have now replicated its qualities in a synthetic self-lubricating material, that only needs occasional infusions of water.
