Making good taste measurable
02-09-2010
Does milk chocolate still contain milk? Or does cheaper vegetable fat already dominate here? Has the barrique wine really seen the inside of a barrique barrel or has it been spiked with flavoured woodchips? Both the products of global food manufacturers as well as small, traditional ...
Paving slabs that clean the air
05-08-2010
The concentrations of toxic nitrogen oxide that are present in German cities regularly exceed the maximum permitted levels. That’s now about to change, as innovative paving slabs that will help protect the environment are being introduced. Coated in titanium dioxide nanoparticles, they reduce ...
Hydrogen causes metal to break
05-08-2010
Hydrogen is considered the fuel of the future. Yet this lightest of the chemical elements can embrittle the metals used in vehicle engineering. The result: components suddenly malfunction and break. A new special laboratory is aiding researchers’ search for hydrogen-compatible metals. Most ...
Test laboratory for solar technology in New Mexico
09-07-2010
Every second, the earth's surface receives roughly as much energy from the sun as it would take to satisfy the energy needs of all of humankind for half a day. If researchers could succeed in harnessing this enormous potential effectively and at a reasonable cost, our energy problems would be ...
Brilliant counterfeit protection
08-06-2010
Counterfeit products create losses in the billions each year. Beside the economic damages, all too often additional risks arise from the poor materials and shoddy workmanship of »knock-off artists«. Yet with the aid of fluorescing dyes, materials can be individually tagged and identified with ...
Materials with potential: growing through holes
25-05-2010
Silicon carbide (4H-SiC) is the ideal semiconductor material for power electronics. For instance, efficient power converters for electric vehicles or photovoltaic systems can be produced - as well as electronics that work at high temperatures. Until now, however, very few electron devices ...
Sharkskin for airplanes, ships and wind energy plants
21-05-2010
To lower the fuel consumption of airplanes and ships, it is necessary to reduce their flow resistance, or drag. An innovative paint system makes this possible. This not only lowers costs, it also reduces CO2 emissions. The inspiration – and model – for the paint‘s structure comes from ...
High efficiency concentrator solar cells and moduls
20-05-2010
Solar energy will play a crucial role in the energy mix of tomorrow as solar energy is available in unlimited quantities. With the aid of concentrator solar cells, even more sunlight can be converted into electricity. Climate change and ever scarcer fossil resources will determine the energy ...
Energy-autonomous sensors in logistics: continuous control of perishable goods
14-05-2010
The safety and quality in the food supply of today’s globally organized and networked supply chain is everything else than warranted. More than 50% of all foodstuffs are spoiled in the transport routes; alone in Great Britain this makes up 17 million tons and approximately 20 billion Euros. ...
Reveal-all scanner for works of art
05-05-2010
Many church paintings are hidden from sight because they were painted over centuries ago. In the 16th century, for instance, Reformation iconoclasts sought to obscure the religious murals, while in later times the iconoclast images often were painted over once again. Several layers of ...
