Tracing the climate back 100 000 years in the Greenland

A three-kilometre-long cylinder of ice sheds light on what the climate was like one hundred thousand years ago. The ice contains traces of periods of higher or lower temperatures on Earth, but also of whether there were violent volcanic eruptions and high solar activity. By understanding the climate of the past, researchers can develop better models to predict the climate of the future. There are...

I-Ju Chen, Yang Chen and Xulu Zeng are all on the track to find better ways of harvesting sunlight using solar cells made of nanowires.

The sunhunters – with knowledge to collect the light

Increased use of solar cells in the future requires higher efficiency and lower production costs. Innovative research from the interdisciplinary centre NanoLund wants to optimize the nanowires so that sunlight can be harvested more efficiently. Meet three young international researchers in the PhD4Energy project, working on hunting the sun. Solar energy, which reaches our earth every day, corresponds to 15,000 times more than all the...

More efficient lubricants using sawdust

Cycling becomes a lot harder if you don’t oil the bicycle chain! Similarly, you can’t cut metal, turn metal on a lathe or press sheet metal without lubricant. Previously in engineering works there was a flow of lubricant that is hazardous for health and the environment, but now the technology exists to reduce consumption of lubricant. In time, the mineral oils used today may be...

Mathematic visualize climate changes

How did we end up here? What do we do to get out of it? In climate research, it is important to understand how the world works if we are to change our behaviour and prevent future catastrophes. Researchers use mathematical formulas to try and visualise reality, in order to find out what changes we need to make. “We build models in an attempt to...
