It is expected that fuel cells will play a significant role in a future sustainable energy system. They are energy efficient and fuel can be produced nearly locally. There are no net emissions of greenhouse gases when a renewable fuel such as ethanol, methanol, biogas and hydrogen is used. Fuel cells reached during the latest years various progresses, but the technology is still in the early phase
Materials with heterogeneous microstructures architected across several scales are becoming increasingly popular in structural applications due to unique strength–ductility balance. One of the most popular 3D-architected structure designs is harmonic structure (HS) where soft coarse-grain (CG) islands are embedded in a hard continuous 3D skeleton of ultrafine grains (UFGs). In this work, a series
We show that high harmonic generation driven by an intense near-infrared (IR) laser can be temporally controlled when an attosecond pulse train (APT) is used to ionize the generation medium, thereby replacing tunnel ionization as the first step in the well-known three-step model. New harmonics are formed when the ionization occurs at a well-defined time within the optical cycle of the IR field. Th
Background: The occupational risk of COVID-19 may be different in the first versus second epidemic wave. Aim: To study whether employees in occupations that typically entail close contact with others were at higher risk of SARS-CoV-2 infection and COVID-19-related hospitalisation during the first and second epidemic wave before and after 18 July 2020, in Norway. Methods: We included individuals in
Semiconductors are vital for information technology, which is why we emphasize this field’s research for high-performance electric and optical devices. Devices and applications based on semiconductors are at the heart of modern society. Within the NanoLund research area of Semiconductor Technology, we aim to develop and understand new materials, structures, and concepts for applications in high-pe

The spin-state of cytochrome b559 (Cyt b559) was studied in photosystem II (PSII) membrane fragments by low-temperature EPR spectroscopy. Treatment of the membranes with 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) converts the native low-spin (LS) form of Cyt b559 to the high-spin (HS) form characterized with the g= 6.19 and g= 5.95 split signal. The HS Cyt b559 was pH dependent with the amplitu
At the nanoscale, electrons and atoms perform random thermal motion and can be subject to quantum effects. Can we use the kinetic energy of electrons to do useful work? Can quantum phenomena make energy conversion more efficient? We combine experiment and theory to explore the fundamentals of generating electricity from heat or light, and the use of information to generate work. A device for st

The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. Both the presence and the flux of water play key role
Spin electronic devices based on crystalline oxide layers with nanoscale thicknesses involve complex structural and magnetic phenomena, including magnetic domains and the coupling of the magnetism to elastic and plastic crystallographic distortion. The magnetism of buried nanoscale layers has a substantial impact on spincaloritronic devices incorporating garnets and other oxides exhibiting the spi
Small-angle neutron scattering is used to study the exchange bias effect in Mn50Ni40Sn10. The martensitic transformation is found to be responsible for the nanometer-scale spin clusters (SCs) inside the low-temperature ferromagnetic (FM) martensite phase. The magnetic field dependences of the SCs and FM domains exhibit an asymmetry that characterizes the exchange bias. We find that the surface geo
Regardless of our socio-juridical position in or outside of organisations, this much is certain: even if not formally employed, we all, Agamben’s Homo Sacer series and the bulk of his other texts imply, are subject to a violence that, if differentially, imprisons us in a world in which ‘work’ reigns supreme. But what precisely is ‘work’? And is there, in spite of our securing the necessities of li
GenerationNano is a Marie-Curie Cofund doctoral programme offering exciting research at the forefront of nanoscience, full-time employment for four years, an international network of cooperation partners and a comprehensive course program. The 14 PhD students that were recruited to the programme had to fulfill the MSCA mobility requirements on top of the general and specific admission requirements

Efficient generation of LHC events is hindered by the rapidly rising cost of evaluating QCD matrix elements with increasing multiplicity. We build on a recently proposed two-step strategy in which unweighted events are first generated using the leading-colour (LC) approximation and then reweighted to full-colour (FC) accuracy, utilising the LC integration efficiency while recovering the exact FC p
This project was performed in collaboration with CellaVision, a company that provides digital solutions for medical microscopy in hematology. Together with a hardware for blood analysis, CellaVision provides a software where cell images are displayed for further analysis. The user interface of this software was the focus of this research. With the aim to provide a suggestion of improvement for the
