U of Minnesota researcher finds materialism in children and adolescents linked to self-esteem
Peer pressure, targeted marketing campaigns and bad parenting have all been blamed for increasing materialism in children. Until now, there has been little evidence showing when this drive for material goods emerges in kids and what really causes it. view more (2007-11-26)
Rubbish reveal even secret things
The contents of rubbish bins are authentic proof of today's consumer habits and current trends. Rubbish does not lie or bend the truth; it reveals everyday secrets and gives insight on ways of life and society. "To an archaeologist rubbish and material remains are concrete sources of information about the past and yesterday's... view more... (2003-02-24)
Nanoparticle technique could lead to improved semiconductors
Devices made from plastic semiconductors, like solar cells and light-emitting diodes (LEDs), could be improved based on information gained using a new nanoparticle technique developed at The University of Texas at Austin. view more (2007-08-07)
New study: Why solar cells lose potency
Commercial products such as laptop computer monitors and solar-powered calculators are constructed from a light-sensitive material with a peculiar problem: When exposed to intense light, it forms defects, reducing the efficiency of the solar cells by 10 to 15 percent. view more (2005-06-20)
Mini-batteries for mobile phones
CIDETEC is working on a project the aim of which is to carry out a direct assessment of the technology of fuel cells for "mini" applications which have between 1 and 10 watt power requirements - such as for mobile phone or PDA chargers or for remote signalling, etc. to this end, a series of technologies are being developed in order to... view more...

Titania nanoparticles could lead to improved sensors and solar energy
Nanostructured titania (TiO2) has been extensively studied as a very promising material for applications in sensors, photocatalysis, solar energy conversion and optical coatings. view more (2005-12-06)
New NIST trace explosives standard slated for homeland security duty
Security personnel need to be able to find explosive materials and persons who have been in contact with them. To aid such searches, the National Institute of Standards and Technology (NIST), with support from the Department of Homeland Security, has developed a new certified reference material, Standard Reference Material (SRM) 2905, Trace... view more...

Material world: graphene's versatility promises new applications
Since its discovery just a few years ago, graphene has climbed to the top of the heap of new super-materials poised to transform the electronics and nanotechnology landscape. view more (2009-07-09)
From trees to high-performance ceramics
When a racing driver brakes, the discs and linings become red-hot. These parts are commonly made of carbon-fiber-reinforced carbon and are black at moderate temperatures. Car manufacturers and their suppliers would dearly like to extend the use of these special brake pads and other hard-wearing parts developed for racing vehicles to perfectly... view more...

NC State breakthrough results in super-hard nanocrystalline iron that can take the heat
Researchers at North Carolina State University have created a substance far stronger and harder than conventional iron, and which retains these properties under extremely high temperatures - opening the door to a wide variety of potential applications, such as engine components that are exposed to high stress and high temperatures. view more (2008-05-28)
Decoding mushroom's secrets could combat carbon, find better biofuels & safer soils
Researchers at the University of Warwick are co-ordinating a global effort to sequence the genome of one of the World's most important mushrooms - Agaricus bisporus. view more (2007-07-18)
Tickling Children's Funny Bones - UU Study
Children say the funniest things, but what makes them laugh? Do German and Israeli kids share the same sense of humour - or is the Simpsons the universal language of laughter? view more (2005-04-18)
Progressive starch products for industry from Finland
New raw materials are proving a technological leap in packaging. view more (2004-08-24)
Ceramic material revs up microwaving
Quicker microwave meals that use less energy may soon be possible with new ceramic microwave dishes and, according to the material scientists responsible, this same material could help with organic waste remediation. view more (2008-08-29)
No Core In Volcanoes
A hot debate in the Earth Sciences is finally resolved in this week's issue of Nature. Researchers from the Department of Earth Sciences at Bristol University show that large volcanoes do not contain material from the Earth's core. This overturns previous theories that conflicted with models of how the Earth's magnetic field is sustained. The... view more... (2004-01-12)
A step toward better brain implants using conducting polymer nanotubes
Brain implants that can more clearly record signals from surrounding neurons in rats have been created at the University of Michigan. The findings could eventually lead to more effective treatment of neurological disorders such as Parkinson's disease and paralysis. view more (2009-09-30)
Rolling wires
Rolls which shape metal strip and wire become worn over the course of time. Rolls made of silicon nitride are more durable than those made of steel. Research engineers conduct work on the measurement, simulation and optimization of sintering and rolling processes. Throughout the world, wire is not only produced by drawing, but in many cases it is... view more... (2002-03-05)
Robotic assembly of fuel cells could hasten hydrogen economy
"The U.S. Department of Energy has suggested that the cost of manufacturing fuel cells is the single biggest obstacle on the road to the hydrogen economy," says Raymond Puffer, co-director of the FMC. view more (2005-11-09)
Catalyst-free chemistry makes self-healing materials more practical
A new catalyst-free, self-healing material system developed by researchers at the University of Illinois offers a far less expensive and far more practical way to repair composite materials used in structural applications ranging from airplane fuselages to wind-farm propeller blades. view more (2007-11-28)
FSU researchers' material may lead to advances in quantum computing
Scientists at Florida State University's National High Magnetic Field Laboratory and the university's Department of Chemistry and Biochemistry have introduced a new material that could be to computers of the future what silicon is to the computers of today. view more (2007-10-09)
