The Wallenberg Initiative Materials Science for Sustainability, WISE, donates SEK 44 million to Linköping University for new scientific equipment that will contribute to cutting-edge materials research.

The largest initiative in materials research in Sweden, WISE, will allocate approximately SEK 500 million to seven affiliated universities to build new research infrastructure. SEK 44 million will be allocated to Linköping University, divided into three projects. In addition to WISE, the Swedish Research Council, the Swedish government’s strategic research area for advanced functional materials (AFM), and Linköping University will also finance parts of the new infrastructure.

Electron microscopy at the atomic level

“It’s extremely important to achieve a basic understanding of how nanostructured and low-dimensional materials behave at the atomic level,” says Per Persson, professor at the Department of Physics, Chemistry and Biology.

X-ray photoelectron spectroscopy

X-ray photoelectron spectroscopy (XPS) is often used to determine the chemical composition of materials. This is currently a standard method in materials science.

But traditional XPS relies on an ultra-high vacuum to work, making it impossible to study materials and liquids as they are “in nature.” This is why a new type of XPS called Near Ambient Pressure X-ray Photoelectron Spectroscopy (NAP-XPS) will be procured.Portrait of Mats Fahlman.Mats Fahlman.

“The new equipment will be optimised to investigate soft and radiation sensitive materials such as organic semiconductors and biological materials. This makes it possible to study, for example, organic solar cells, batteries or biosensors during operation,” says Mats Fahlman, professor at the Department of Science and Technology, ITN.

Additive manufacturing

According to Simone Fabiano, senior associate professor at ITN, the purpose of the project is to expand the additive manufacturing capabilities at LiU. They want to be able to work with 3D printing and manufacturing of components based on organic electronics. Simone Fabiano.Simone Fabiano. Photo credit Thor Balkhed

The Printed Electronics Arena test bed at LiU currently has the expertise for additive manufacturing using both metals and soft materials, such as conductive plastics (which is the basis of organic electronics). However, the current equipment has relatively low resolution and it is only possible to print in 2D.The new equipment will complement that which is already in place, enabling the development of new organic electronics with great precision and in three dimensions.

About WISE

WISE is a collaboration between Chalmers University of Technology, KTH Royal Institute of Technology, Luleå University of Technology, Uppsala University, Stockholm University, Lund University and Linköping University, which also hosts the programme.

It is funded by the Knut and Alice Wallenberg Foundation and the total budget is just under SEK 3 billion for the period 2022–2033.

Simple methods made teachers better at teaching

All teachers improved their teaching considerably after receiving visits and feedback from experts on their performance during lessons. This is shown in a report from Linköping University that compiled observations from 30 compulsory schools.

LiU researchers are among the first in the world to have grown human nasal tissue from stem cells. It is used to study how different viruses infect the airways.

WASP extended with a new initiative: AI for Science

Knut and Alice Wallenberg Foundation grants SEK 70 million to WASP for a new initiative that promotes the uptake of AI based methodologies in academic research in Sweden.
