Tailoring Auger Recombination Dynamics in CsPbI3 Perovskite Nanocrystals via Transition Metal Doping

Auger recombination is a pivotal process for semiconductor nanocrystals (NCs), significantly affecting charge carrier generation and collection in optoelectronic devices. This process depends mainly on the NCs’ electronic structures. In our study, we investigated Auger recombination dynamics in manganese (Mn2+)-doped CsPbI3 NCs using transient absorption (TA) spectroscopy combined with theoretical

The SAM-Krom biomonitoring study shows occupational exposure to hexavalent chromium and increased genotoxicity in Denmark

Background Hexavalent chromium (Cr(VI)) is a carcinogen. Exposure to Cr(VI) may occur in different industrial processes such as chrome plating and stainless steel welding. The aim of this study was to assess occupational exposure to Cr(VI) in Denmark. Methods This cross-sectional study included 28 workers and 8 apprentices with potential Cr(VI) exposure and 24 within company controls, all recruite

The Influence of bipolar plate wettability on performance and durability of a proton exchange membrane fuel cell

A significant surface wettability transition from hydrophobicity to hydrophilicity after long-term operation is observed in graphite bipolar plates of a proton exchange membrane fuel cell (PEMFC). Extensive in-situ electrochemical characterization was performed to investigate the impact of bipolar plate wettability on the performance and durability of two PEMFCs (named “New cell” and “Old cell”),

Underground Waterlines : Explaining Political Quiescence of Ukrainian Labor Unions

In order to explore factors conditioning the political quietude of Ukrainian labor, this article analyzes ethnographic data collected at two large enterprises: the Kyiv Metro and the privatized electricity supplier Kyivenergo. Focusing on a recent labor conflict, I unpack various contexts condensed in it. I analyze the hegemonic configuration developed in the early 1990s, at the workplace and at t

Numerical and experimental investigations of flow features over a wedge exposed to supersonic flow at high Reynolds numbers

Numerical simulation tools and experimental measurement techniques are required to provide accurate description of flow features in application relevant scales and boundary conditions enroute to realizing the design and integration of high-speed arial platforms. A case of 10° wedge exposed to Mach 3.5 supersonic flow at high Reynolds numbers provides an opportunity to conduct a comparative analysi

Towards alternative ecologies of encounter: crafting a vital materialist perspective of cultural entrepreneurship

In the wake of an aesthetic capitalism, the cultural and creative industries (CCI) have become a growing and thriving sector of Western and other economies. Cultural entrepreneurial processes propel the CCI and their regime of aesthetic innovation and constitute constantly evolving art worlds. My dissertation focuses on the material-affective dimensions of these art worlds. It explores cultural en

Negotiating and sustaining temporary organizing through affective practices

In this study I investigate how collaborative relations in temporary organizing are mobilized and aligned towards a creative vision using affective practices. Building on the current literature, I argue that affective relations are a central to understanding the tension ridden negotiations of collaborative relations in temporary organizing. I draw upon the notion of affective practices to conceptu

Getting into the Vibe: Affective temporality and collaborative creativity in recording studios

Although the relationship between time and creativity has fascinated scholars for centuries, little attention has been paid to the temporality of creative work, particularly in collaborative settings. In this paper, we turn to the recording studio as a particularly useful context to understand different feelings of time shape collaborative creativity. We mobilize the concept of affective temporali

Utility of interleukin-6 to identify serious bacterial infections in febrile infants aged ≤60 days

AIM: The aim of this study is to investigate the utility of interleukin-6 (IL-6) in the early diagnosis of serious bacterial infections (SBI) in febrile infants and to compare it with C-reactive protein (CRP).METHODS: Retrospective study conducted in the paediatric emergency department in Gothenburg, Sweden, on previously healthy, full-term infants aged ≤60 days with fever without a source (FWS) f

Aging enacted in practice : How unloved objects thrive in the shadows of care

In this paper, we explore the seeming stability of aging. More precisely, we offer an empirical account of how aging – images of aging, embodiments of aging, feelings about aging – is enacted in company practice, both in place and across time. Drawing on ethnographic fieldwork conducted at SMCare, a small-to-medium sized company active in the care technology sector, we show how aging achieves its

Estimating glomerular filtration in young people

BACKGROUND: Creatinine-based equations are the most used to estimate glomerular filtration rate (eGFR). The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), the re-expressed Lund-Malmö Revised (r-LMR) and the European Kidney Function Consortium (EKFC) equations are the most validated. The EKFC and r-LMR equations have been suggested to have better performances in young adults, but this

SILMAS Structured Illumination Light-sheet Microscopy with Axial Sweeping: 3D imaging of brain tissue

Modern healthcare allows people to live longer and healthier lives. However, as the average lifespan increases, age-related diseases are becoming more prevalent. Neuroscientists are therefore increasingly focused on understanding and developing treatments for neurodegenerative disorders, such as Alzheimer's and Parkinson's disease. These conditions are characterized by progressive neuronal degener

Mental health symptom burden in elite ice hockey players and its association with self-reported concussive events

Some studies suggest that elite athletes experience adverse mental health symptoms at rates commensurate with the general population, despite the well-established buffering effects of exercise. Within contact sports, such as ice-hockey, recurrent concussions may be a source of this discrepancy. We compared the point prevalence of various mental health outcomes with other athlete and general popula
