Concrete is the world's most widely used building material – but the production of cement, its key component, generates significant carbon dioxide emissions. New research at Umeå University shows how electrification and carbon capture can make production both more energy-efficient and climate-smart.
When heavy machinery is to become robots with autonomous capabilities, safety is at highest priority. In a new EU project, researchers and industry collaborate to develop reliable and efficient AI-driven machines that minimize the risk of harming people or the environment.
Researchers at Umeå University have revealed details on how bacteria use calcium to regulate vital processes, in a way that differs from human cells. This breakthrough is significant in the fight against antibiotic resistance and for increasing safety in food production.
For the first time, scientists have succeeded in creating a self-driving forest machine controlled by artificial intelligence. In a research study at Umeå University, Sweden, an AI system was developed that can operate the 16-ton machine without human intervention. The study has been carried out in collaboration with Skogforsk and Algoryx Simulation.
The carbon dioxide emissions of the growing human population have a massive impact on the climate. While many are seeking solutions, researchers in Umeå, Sweden, might have found one right in front of their houses: Nordic microalgae. A thesis from the Industrial Doctoral School at Umeå University shows that microalgae fed on wastewater can be used to produce degradable bioplastic.
Air moisture landing on surfaces of materials forms thin, invisible, water films. These films play crucial roles in Earth’s soils and atmosphere as well as in new technologies. A thesis at Umeå University sheds new light on how this silent architect mediates chemical reactions.
A newly developed instrument makes it possible to measure gas pressure by using laser light. The method, developed at Umeå University and the Industrial Doctoral School for Research and Innovation, provides very precise measurements and can, for example, quickly detect extremely small gas leaks.
Researchers found how to convert cost free forest waste, like pine cones, into carbon materials useful for energy storage. The method allows for easy and environmentally friendly dispersion of carbon in water, even when it is not water-soluble. The blend can then be sprayed onto a surface to produce electrodes for supercapacitors.
Artificial membranes play a vital role in healthcare, energy storage and resource recovery. However, the fabrication is not environmentally friendly. In a thesis from Umeå University, Norafiqah Ismail introduces alternative solvents that outperforms traditional toxic ones in terms of cost, sustainability, and performance.
