Best Transport Connections with Quick Algorithms

Relying on public transport as a newcomer or occasional user can be rather stressful. For some years now, apps have been helping users to find the right bus or train. What many users do not know: The digital helpers do not always tell us the best route when considering e.g. the number of changes of Read more about Best Transport Connections with Quick Algorithms[…]

Global Impacts of Agriculture on Climate Change

Together with carbon dioxide and methane, nitrous oxide is among the most important greenhouse gases: It is about 300 times more hazardous to the climate than carbon dioxide. In Germany, the main source of nitrous oxide emissions is agriculture and its extensive use of nitrogen fertilizers. Potential consequences on food production and climate change will Read more about Global Impacts of Agriculture on Climate Change[…]

3D Nanoprinting Facilitates Communication with Light

At Karlsruhe Institute of Technology (KIT), researchers have developed a flexible and efficient concept to combine optical components in compact systems. They use a high-resolution 3D printing process to produce tiny beam-shaping elements directly on optical microchips or fibers and, hence, enable low-loss coupling. This approach replaces complicated positioning processes that represent a high obstacle Read more about 3D Nanoprinting Facilitates Communication with Light[…]

Semitransparent organic solar cells in eyeglasses to power microprocessor

Organic solar cells are flexible, transparent, and light-weight – and can be manufactured in arbitrary shapes or colors. Thus, they are suitable for a variety of applications that cannot be realized with conventional silicon solar cells. In the Energy Technology journal, researchers from KIT now present sunglasses with colored, semitransparent solar cells applied onto lenses Read more about Semitransparent organic solar cells in eyeglasses to power microprocessor[…]

Turning Research into Innovations

The European Research Council (ERC) has decided to fund two innovative ideas of Karlsruhe Institute of Technology (KIT). For their first steps from fundamental research to commerciali-zation, these projects are now granted about EUR 150,000 each. The so-called “Proof of Concept Grants” serve to further de-velop application-relevant research findings for the market. The KIT projects Read more about Turning Research into Innovations[…]

Development of Metamaterial with Novel Properties

The Middle Ages certainly were far from being science-friendly: Whoever looked for new findings off the beaten track faced the threat of being burned at the stake. Hence, the contribution of this era to technical progress is deemed to be rather small. Scientists of Karlsruhe Institute of Technology (KIT), however, were inspired by medieval mail Read more about Development of Metamaterial with Novel Properties[…]

First Time Integrate Organic Lasers on a Silicon Photonic Chip

In the area of nano photonics, scientists for the first time succeeded in integrating a laser with an organic gain medium on a silicon photonic chip. This approach is of enormous potential for low-cost biosensors that might be used for near-patient diagnosis once and without any sterilization expenditure similar to today’s strips for measuring blood Read more about First Time Integrate Organic Lasers on a Silicon Photonic Chip[…]

Computer Simulation Discloses New Effect of Cavitation

Researchers have discovered a so far unknown formation mechanism of cavitation bubbles by means of a model calculation. In the Science Advances journal, they describe how oil-repellent and oil-attracting surfaces influence a passing oil flow. Depending on the viscosity of the oil, a steam bubble forms in the transition area. This so-called cavitation may damage Read more about Computer Simulation Discloses New Effect of Cavitation[…]
