Researchers have developed a compound that can transform near-infrared light into broadband white-light, offering a cheap, efficient means to produce visible light.
The emitted light is also exceedingly directional, a desirable quality for devices like microscopes that require high spatial resolution, or for applications with high throughput, such as projection systems. Nils Wilhelm Rosemann and colleagues designed their compound of tin and sulfur, and with a diamondoid-like structure, then coating this scaffolding with organic ligands.
As a state university it no longer has any religious affiliation.
It was the main university of the principality of Hesse and remains a public university of that German state. It now has about 25,000 students and 7,500 employees, making Marburg, a town of 72,000 inhabitants, the proverbial “university town” (Universitätsstadt). Though most subjects are grouped, the University of Marburg is not a campus university in the broader sense. About 12% of the students are international, the highest percentage in Hesse. It offers an International summer university programme every summer and has an awarded ERASMUS programme.
Marburg is home to one of Germany’s most traditional medical faculties. The German physicians’ union is called “Marburger Bund”.
