During the spring of 2020 the world was hit by the Covid-19 pandemic which led to unpredicted and interesting effects in the domestic tourism sector. As a result of travel restrictions and social distancing recommendations there was an increase in visitors to national parks, hiking trails and other recreational areas in Sweden. The amount of visitors to the High Coast trail located in the east of
An increase of dissolved organic carbon (DOC) from rivers into coastal waters has been observed in previous studies, leading to an increase in hypoxic zonesin coastal areas when the bioavailable fraction of the DOC is degraded causing harm to ecosystems and negatively affecting ecosystem services vital for society. The first part of this study investigates if constructed wetlands can be used a
The transport sector is responsible for a third of Swedens’ total GHG emissions, where the private cars are a large part of this. Sweden is committed to reducing the emissions from the transport sector with 70 % until the year 2030. Shifting the vehicle fleet to electrical will be one important factor in achieving the goal, but such technical innovation will not be enough. To reach a more sust
The agricultural sector is both affecting and affected by climate change. Future climate is predicted to be warmer and wetter with more weather extremes. This is going to affect the already vulnerable agricultural sector and we need to strengthen our food production and food security. Therefore, agriculture needs to adapt to climate change to prevent negative effects but also to utilize the p
The purpose of this study was to examine narratives from people who went from the assigned gender boy or girl, to the opposite binary gender identity, concerning differences in treatment from others, before and after a transition. Data were collected through a survey administered online, a total of fourteen questions about how their emotions were met before and after the transition. Questions were
Increased carbon sequestration in agricultural land is an important measure to reduce global warming. Since the soil is a large carbon sink, a small change in the soil organic carbon (SOC) stocks can make a substantial difference to the carbon dioxide content in the atmosphere. An increase in SOC improves the soil health and fertility which in turn gives better yields and a more secure food supply
The degradation of ecosystems and the loss of biodiversity occurs at an alarming rate. This results in an imbalance of ecosystem functions, leading to a loss of ecosystem services. Ecosystem services are benefits which humans can derive from ecosystems and their internal processes, thus vital to preserve from a societal perspective. The purpose of this study was to explore the possibilities for
Climate change is a global threat to human and animals’ well-being on Earth. The threat of climate change has been known for over 30 years and it is now a fact that humans are the main contributing factor to it. Despite this, in 2022 it is no longer an abstract phenomenon, but our reality. One of the reasons why so little has been done to save the environment is people’s lack of or insufficient kn
Microsoft Word - Decarbonisation Laboratory.docx Decarbonisation Laboratory Klimatförändringen är en av vår tids stora övergripande frågor och den har ofta inramats som en fråga om att nå kollektiva överenskommelser och därefter implementera de överenskomna åtgärderna som kan uppnå dessa mål. Klimatfrågan ses då som ett ”föroreningsproblem” som kan hanteras genom ”end-of-pipe” lösningar. Forskning

Photoluminescence (PL) of organo-metal halide perovskite semiconductors can be enhanced by several orders of magnitude by exposure to visible light. We applied PL microscopy and super-resolution optical imaging to investigate this phenomenon with spatial resolution better than 10 nm using films of CH3NH3PbI3 prepared by the equimolar solution-deposition method, resulting in crystals of different s
Telomere length has been associated with risk of many cancers, but results are inconsistent. Seven single nucleotide polymorphisms (SNPs) previously associated with mean leukocyte telomere length were either genotyped or well-imputed in 11 108 case patients and 13 933 control patients from Europe, Israel, the United States and Australia, four of the seven SNPs reached a P value under .05 (two-side
The development of a ternary AlxIn1-xP shell grown around GaAs nanowires epitaxially grown in the [(1) over bar (1) over bar (1) over bar] direction has been studied. Morphology and composition of the shell have been studied using cross-sectional transmission electron microscopy (TEM). The side facets of the shell are found to develop dominant {1 (1) over bar 0} macro facets with small (approx. 5
We present dc and RF characterization of InAs nanowire field-effect transistors (FETs) heterogeneously integrated on Si substrates in a geometry suitable for circuit applications. The FET consists of an array of 182 vertical InAs nanowires with about 6-nm HfO high-gate dielectric and a wrap-gate length of 250 nm. The transistor has a transconductance of 155 mS/mm and an on-current of 550 mA/mm at
III-V Nanowires (NWs) grown with metal-organic chemical vapor deposition commonly show a polytypic crystal structure, allowing growth of structures not found in the bulk counterpart. In this paper we studied the radial overgrowth of pure wurtzite (WZ) GaAs nanowires and characterized the samples with high resolution X-ray diffraction (XRD) to reveal the crystal structure of the grown material. In
Semiconductor-oxide heterointerfaces have several electron volts high-charge carrier potential barriers, which may enable devices utilizing quantum confinement at room temperature. While a single heterointerface is easily formed by oxide deposition on a crystalline semiconductor, as in MOS transistors, the amorphous structure of most oxides inhibits epitaxy of a second semiconductor layer. Here, w
Axially defined GaInP single nanowire (NW) p-i-n junctions are demonstrated, with photocurrent response and yellow-green electroluminescence near the indirect bandgap crossover point at 2.18 eV (569 nm). We use DEZn and H2S as p- and n-type dopants, and find that they both affect the material composition and the crystal structure. The photovoltaic efficiency is comparable to single NW devices from
Some patients with chronic obstructive pulmonary disease (COPD) show increased airway inflammation and bacterial colonization during stable phase. The aim of this study was to follow COPD patients and investigate chronic colonization with pathogenic bacteria during stable disease phase, and relate these findings to clinical parameters, inflammatory pattern, lung function, and exacerbations.
We present temperature dependent electrical measurements on n-type InAs/InSb nanowire heterostructure field-effect transistors. The barrier height of the heterostructure junction is determined to be 220 meV, indicating a broken bandgap alignment. A clear asymmetry is observed when applying a bias to either the InAs or the InSb side of the junction. Impact ionization and band-to-band tunneling is m
