During her years as a researcher and data protection commissioner, the German computer scientist Marit Hansen has been a pioneer for the concept of privacy enhancing technologies (PET).
A virtual paper-making machine makes it possible to test run and optimise operations without costly downtime in the industry. New research at Karlstad University saves money and spares the environment.
”It is now possible to run the paper-making process virtually, without expensive equipment, to identify the optimal settings for each machine,” says Björn Sjöstrand, who recently submitted his doctoral thesis in chemical engineering at Karlstad University.
Research at Karlstad University shows that sludge and ashes as paper mill residues can be used as effective fertiliser. This involves biochar, that is, carbon from organic material returned to the forest and thus closing the cycle.
"Biochar has many beneficial effects on the environment," says Maria Sandberg, senior lecturer in environment and energy systems and research leader for the project.
At Karlstad University, there is research on polymer solar cells and how these can be made more stable and effective. Recently, a doctoral thesis was presented on how solar cell materials and functions are affected by contact with air and light.
”By now, almost everybody agrees that climate change is real,” says Vanja Blazinic, PhD in physics. ”We need to phase out fossil fuels and transit to renewable energy sources like sun, wind and water.
Since 2016, a partnership, called MIRAI, has been in operation between Swedish and Japanese universities. Next year marks the start of a new period for the MIRAI partnership with more Swedish and Japanese universities involved in research, education and innovation collaboration.
Did you know that it is possible to use mathematical models to calculate how best to repair a broken blood vessel? And that it is possible to find out what tire groove gives the best grip on wintry roads?
The launch of the 5G network is approaching and the expectations are great. Both individuals and businesses are looking forward to higher speed, minimal delays, and the possibility of handling a greater number of connected devices simultaneously. But how do we make optimal use of the potential offered by 5G technology?
The last two weeks the CCS, Centre for Climate and Safety at Karlstad University has been visited by two experts on natural disaster modelling from the US Federal Emergency Management Agency, FEMA.
Jesse Rozelle, the Acting Branch Chief for FEMA HQ’s Actuarial and Catastrophic Modeling Branch, and Casey Zuzak, a Senior Risk Analyst for Hazus and the Natural Hazards Risk Assessment Program (NHRAP) are in Karlstad in connection to a research project funded by the Swedish Ci
Doctor Natalie Holmes, organic electronics researcher at the University of Newcastle in Australia, is currently spending two months at Karlstad University as a visiting researcher.
Seke Chainda, a student in the Biology Master's Program at Karlstad University, has been named Global Swede of 2019. On May 21 he was celebrated, together with other Global Swede students, at a ceremony at the Ministry for Foreign Affairs.
On May 21 the distinction Global Swede was conferred on twenty-six international top students from Swedish institutions of higher education.
Lars Järnström, professor of coating technology, came to Karlstad University in 1999 and has been involved in building the current strong research environment for fibre-based processes and products. Now retirement is approaching but he will continue working at the university as senior professor.
Lars Järnström's research centres mainly on environment-friendly surface treatment of fibre-based packaging materials.
The cocktail of man-made chemicals that we are exposed to daily is a health risk which current regulations and risk assessment overlook. This is the conclusion of the EU Horizon 2020 EDC-MixRisk project that is now being presented.
We are exposed to a large number of man-made chemicals in our everyday life. This creates combinations of chemical mixtures, to which we are subjected during our whole lifespan.
The world needs more efficient energy systems based on renewable raw material, an equation not easily solved. At Karlstad University, research and education are in progress to find sustainable energy systems, for instance, through a project in which pellets replace charcoal in cooking solutions in Zambia, because cooking with charcoal as fuel leads to extensive deforestation as well as health hazards.
Carbon based nano materials such as graphene and carbon nanotubes were predicted a brilliant future when they were discovered. But quality problems curb the development of new products. The problem is that it is difficult to analyse the crystal structure and there are no established standard methods for classifying the materials.
Podcast dramas that enhance the listening experience through interactive effects have become reality through a collaboration between dramatist Amanda Fromell and computer technology students at Karlstad University.
An important part of packaging is the printed packaging surface, communicating a message to the consumers. Poor printing quality can affect the perception of the packaging as well as the product.
Adrian Muntean, Professor of Mathematics at Karlstad University, has been awarded funding by the Swedish Research Council to study the transport of matter through thin heterogeneous layers, that is, thin barriers preventing the free movement of particles.
Old sewer pipes that break down may cause a lot of damage. In the worst case, leaking water erodes the soil and this may result in sinkholes. Now researchers at Karlstad University have created a mathematical model to calculate the corrosion of sewers. This is important in selecting materials for future sewer lines.
Before creating a new type of sewer pipe that needs to function for decades, the user has to be able to obtain an estimate of the rate of corrosion.
