All inorganic halide perovskites in the form of colloidal quantum dots (QDs) have come into people's view as one of the potential materials for the high-efficiency solar cells; nevertheless, the high surface trap density and poor stability of QDs restrict the performance improvement and application. Here, we obtain colloidal inorganic perovskite CsPb1-xZnxI3 QDs by the hot-injection synthesis proc
In this article, the success of a risk communication programme conducted in two municipalities in Sweden is evaluated. The communication efforts were initiated in order to comply with the Seveso II Directive, passed as a national law in July 1999. Data from two different questionnaires are used. Between the distribution of the two questionnaires, an information campaign took place in the communiti
The European Spallation Source, currently under construction in Lund, Sweden, will be the world's most powerful neutron source. It is driven by a proton linac with a current of 62.5 mA, 2.86 ms long pulses at 14 Hz. The final section of its normal-conducting front-end consists of a 39 m long drift tube linac (DTL) divided into five tanks, designed to accelerate the proton beam from 3.6 MeV to 90 M
The core-multishell wurtzite structure (In,Ga)As–(Ga,Al)As–(Ga,Mn)As semiconductor nanowires have been successfully grown on GaAs(111)B substrates using MBE technique. The nanowires cores were grown with gold eutectic catalyser in vapour–liquid–solid growth mode. The double shell overgrowth, on the side facets of nanowires, was performed using lower substrate temperature (about 400 ◦C, and 230 ◦C,
A radioactive fallout following a nuclear accident can result in contamination of large areas of land. In order to protect human health against ionizing radiation, large-scale decontamination that includes multiple sets of clean-up measures may be necessary. Sweden lacks national experience of this type of large-scale decontamination. There are thus great uncertainties in the effect of such a deco
Collective collapse occurs when a majority of the players in a team suddenly perform below expected level in a match, in spite of a satisfactory start, or when a team underperforms right from the start. Research results from a study on 146 male players and 15 coaches in various team sports at the elite level, and a study on a team involved in a collective collapse, and the opposite, a winning turn
Wetland area in agricultural landscapes has been heavily reduced to gain land for crop production, but in recent years there is increased societal recognition of the negative consequences from wetland loss on nutrient retention, biodiversity and a range of other benefits to humans. The current trend is therefore to re-establish wetlands, often with an aim to achieve the simultaneous delivery of mu
European Union challenges and crises of the past decade, including the Eurozone sovereign debt crisis, refugees, ethno-nationalist/Brexit movements, COVID-19, and Russian invasion of Ukraine are part of a planetary organic crisis (POC) of economy, society, ecology, conflict, and polity. The recognition of the symbiotic relationships between these challenges is crucial for moving from symptoms to c
Functional magnetic resonance imaging (fMRI) is increasingly used to non-invasively study the acute impact of psychedelics on the human brain. While fMRI is a promising tool for measuring brain function in response to psychedelics, it also has known methodological challenges. We conducted a systematic review of fMRI studies examining acute responses to experimentally administered psychedelics in o
In this study, Raman spectroscopy has been used to evaluate the evolution of the structural modification of soot during oxidation processes at various preset temperatures up to 700 °C. Two types of well-characterized mini-CAST soot, representing black soot and brown soot, were examined. The major difference between the signals from the two types of soot was the higher photoluminescence (PL) signal
Free energy calculations play a crucial role in simulating chemical processes, enzymatic reactions, and drug design. However, assessing the reliability and convergence of these calculations remains a challenge. This study focuses on single-step free-energy calculations using thermodynamic perturbation. It explores how the sample distributions influence the estimated results and evaluates the relia
Translation is an essential genetic process for understanding the mechanism of gene expression. Due to the large number of protein sequences generated in the post-genomic era, conventional methods are unable to identify Translation Initiation Site (TIS) in human genes timely and accurately. It is thus highly desirable to develop an automatic and accurate computational model for identification of T
Pierre Bourdieu's writings on the state consist of a series of more or less coherent investigations approaching the state from different angles. His writings on the state may seem to contain internal ambiguities. On the one hand, they argue for an actor-centered approach to the state while, on the other hand, elaborating the power of the state as an institution transcending these actors. The purpo
This paper investigates how early career academics interpret and respond to institutional demands structured by projectification. Developing a ‘frame analytic’ approach, it explores projectification as a process constituted at the level of meaning-making. Building on 35 in-depth interviews with fixed-term scholars in political science and history, the findings show that respondents jointly referre
Recent years have seen dramatic improvements in computer power, allowing ever more challenging problems to be approached. In light of this, it is imperative to have a quantitative model for examining chemical reactivity, both in the condensed phase and in solution, as well as to accurately quantify physical organic chemistry (particularly as experimental approaches can often be inconclusive). Simi
BACKGROUND: Treatment for breast cancer poses major challenges and leads to a variety of side-effects and problems that affect life for a long time. Experiences and symptoms vary, and research indicates a lack of structures for ensuring individualized rehabilitation. This qualitative focus group study aims to explore the experience of women with BC after participating in a complex randomized contr
The integration of rare disease medical databases belonging to different countries is an important problem, as a large number of observations are required for reliable statistical inference of patient data in order to facilitate clinical research. Such integration of national registry data, which requires harmonization of the heterogeneous data sets into a unified view, is facilitated in the Europ
Despite the potential of smart home technologies (SHT) to support everyday activities, the implementation rate of such technology in the homes of older adults remains low. The overall aim of this study was to explore factors involved in the decision-making process in adopting SHT among current and future generations of older adults. We also aimed to identify and understand barriers and facilitator
This thesis focuses on the optimization and control of laser-driven plasma-based acceleration, whichinvolves the driver laser pulse, the accelerated electrons and the subsequent generation of x-rays.In laser wakefield acceleration (LWFA), a high-power laser pulse, typically with terawatt-levelpower, is focused tightly into a gas, reaching intensities on the order of > 1018 W/cm2. Even at the leadi
