Magnesium

Magnesium alloys are very attractive for a range of weight-sensitive applications. They have the largest strength-to-weight ratio of the common structural metals, are lighter than aluminum and are particularly favored for being easy to machine and for their ability to be die cast to net shape. Unfortunately, magnesium alloys tend to corrode too easily. A team at Monash University in Australia has now discovered a novel and potentially game-changing approach to the problem: poisoning the chemical reactions leading to corrosion of magnesium alloys by adding a dash of arsenic to the recipe.  Read More

A sample of Upsalite

In an effort to create a more viable material for drug delivery, a team of researchers has accidentally created an entirely new material thought for more than 100 years to be impossible to make. Upsalite is a new form of non-toxic magnesium carbonate with an extremely porous surface area which allows it to absorb more moisture at low humidities than any other known material. "The total area of the pore walls of one gram of material would cover 800 square meters (8611 sq ft) if you would 'roll them out'", Maria Strømme, Professor of Nanotechnology at the Uppsala University, Sweden tells Gizmag. That's roughly equal to the sail area of a megayacht. Aside from using substantially less energy to create drier environments for producing electronics, batteries and pharmaceuticals, Upsalite could also be used to clean up oil spills, toxic waste and residues.  Read More

The WaterBean portable water filter

It's a given that recycling waste products is a good thing. It's certainly better than sending our trash to landfill where it will sit rotting (or not, in the case of non-biodegradable waste) for decades to come. However, even better than recycling is to not create the waste in the first place. Bottled water is now big business, and more popular than ever before, but bottled water guzzles energy and creates waste that really doesn't need to be created. WaterBean offers one possible solution to the problem.  Read More

The GH-LED10WBW is intended for use in emergencies, and for recreation

Every now and again, a rumor crops up that someone has invented a motor car that runs on water. Sadly, that still remains a rumor, but Green House Co Ltd of Japan will soon be marketing an LED lantern that runs on saltwater.  Read More

A new method for graphene production has been discovered, that involves burning pure magne...

Graphene, the one-atom-thick carbon sheet material that could revolution everything from energy storage to computer chips, can now be made much more easily – at least, that’s what scientists from Northern Illinois University (NIU) are telling us. While previous production methods have included things like repeatedly splitting graphite crystals with tape, heating silicon carbide to high temperatures, and various other approaches, the latest process simply involves burning pure magnesium in dry ice.  Read More

NIST postdoctoral researcher James Chin-wen Chou with the world's most precise clock that ...

Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom that would neither gain nor lose one second in about 3.7 billion years. That makes it the world’s most precise clock, more than twice as precise as the previous pacesetter based on a mercury atom.  Read More

Researchers have discovered that higher levels of magnesium in rats enhanced their learnin...

Your mother was right – eating your “greens” (which contain magnesium) is good for you. In fact, according to neuroscientists at MIT and Tsinghua University in Beijing, rats who were fed a new compound that increased their brain magnesium demonstrated enhanced learning abilities, working memory, and short- and long-term memory. The dietary supplement also boosted older rats’ ability to perform a variety of learning tests. Great, if it’s not hard enough getting rid of the rodents now, imagine trying to remove smarter rats!  Read More

The HP Envy 13 with aluminum and magnesium casing

If ya can’t beat 'em, look like ‘em. That seems to be the ethos at HP with the unveiling of its slim new Envy line of notebooks, which take a fair few visual cues from Apple’s MacBook Pro – not that there’s anything wrong with that.  Read More

The pedal/electric powered Gocycle

April 9, 2009 One of the most compelling examples of urban transportation we've seen in recent times, the Gocycle is a lightweight electric bike developed with professionals and families in mind which brings a number of style and performance firsts to city-specific two-wheelers. Gocycle’s design engineer and founder of Karbon Kinetics Limited (KKL), Richard Thorpe, cut his teeth working in lightweight vehicle design for companies such as McLaren and turned his attention to bicycles in an attempt to break the mould of conventional design - and with its lightweight magnesium alloy construction, push-button access to electric propulsion and an innovative enclosed multi-speed chain-drive, the Gocycle does just that.  Read More

Dell XFR rugged laptop on truck tailgate

Designed for workplace applications which place large demands on your laptop like manufacturing, military, mining and oil and gas exploration, Dell's new rugged laptop - the Latitude E6400 XFR - boasts "ballistic armor" said to provide twice the impact strength of Magnesium alloy, plus higher drop specifications and enhanced protection against dust and water.  Read More
