New electrolyte to enable cheaper, less toxic magnesium-sulfur-based batteries

By - November 30, 2014
There's another promising contender in the race to supplant the dominance of lithium-ion and metal-hydride based batteries in the world of energy storage. New research from the Karlsruhe Institute of Technology's (KIT's) Helmholtz Institute Ulm (HIU) details the development of an electrolyte that can be used in new magnesium-sulfur battery cells that would be more efficient and inexpensive than the dominant types of batteries in use today.

Stainless magnesium breakthrough bodes well for manufacturing industries

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.

Scientists make "Impossible Material" ... by accident

By - July 30, 2013 7 Pictures
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.

WaterBean purifies tap water to reduce plastic bottle waste

By - July 28, 2013 3 Pictures
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

'Simple, green, and cost-effective' method of graphene production announced

By - June 21, 2011
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.

Increasing magnesium intake can boost brainpower - at least in rats

By - January 29, 2010
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!

Gocycle: The fold-up electric bicycle fit for the 21st century

By - April 9, 2009 14 Pictures
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.
