Fluorescent InP-based quantum dots have emerged as valuable nanomaterials for display technologies, biological imaging, and optoelectronic applications. The inclusion of zinc can enhance both their emissive and structural properties and reduce interfacial defects with ZnS or CdS shells. However, the sub-particle distribution of zinc and the role this element plays often remains unclear, and it has
Lateral dimensions of III-V nanowires are known to affect the growth dynamics and crystal structure. Investigations into size effects have in the past relied on theoretical models and post growth observations, which only give a limited insight into the growth dynamics. Here we show the first experimental investigation into how nanowire diameter affects the growth dynamics by growing Au-seeded GaAs
Aim: Bridge to surgery (BtS) aims to decrease perioperative morbidity and mortality in emergency resection (ER) of the colon. Previous results are inconsistent, and long-term comparisons are scarce. The aim of this study was to compare the short- and long-term outcomes of BtS and ER. Method: This retrospective study examined data from the Swedish Colorectal Cancer Registry for patients treated for
Ökat användande av testautomation föranleder en grundläggande fråga: Hur tillförlitliga är egentligen alla dessa automatiserade tester? Inom den akademiska forskningen anses mutationstestning vara den mest lovande tekniken för att bedöma en testsvits förmågas att upptäcka fel. Tekniken introducerar avsiktligt fel (så kallade mutanter) i produktionskoden och utvärderar hur många av felen som upptäcThe growing reliance on automated software tests raises a fundamental question: How trustworthy are these automated tests? Today, mutation testing is acknowledged within academic circles as the most promising technique for assessing the fault-detection capability of a test suite. The technique deliberately injects faults (called mutants) into the production code and counts how many of them are cau
The transport sector accounted for 37% of global CO2 emissions from end-use sectors in 2021. For the transport- and road freight sector to contribute to emissions reduction targets while still meeting the foreseen increase in transport demands, decarbonization will play a key role. This study focus on battery-electric heavy-duty trucks and the objective is to provide an overview of policy instrume
Neuron generation persists throughout life in the hippocampus but is altered in animal models of neurological and neuropsychiatric diseases, suggesting that disease-associated decline in cognitive and emotional hippocampal-dependent behaviours might be functionally linked with dysregulation of postnatal neurogenesis. Depletion of the adult neural stem/progenitor cell (NSPCs) pool and neurogenic de
In this study, a Eulerian-Lagrangian model is used to study biomass gasification and release of potassium species in a 140 kW atmospheric entrained flow gasifier (EFG). Experimental measurements of water concentration and temperature inside the reactor, together with the gas composition at the gasifier outlet, are used to validate the model. For the first time, a detailed K-release model is used t
We consider the problem of sharing sensitive files across users while relying on a common, untrusted third-party, e.g., a Cloud Storage Provider (CSP). Although users can rely on a secure peer-to-peer (P2P) channel for file sharing, this introduces potential delay on the data transfer and requires the sender to remain connected while the transfer process occurs. Instead, users can upload informati
There is an increasing interest in understanding the atomic level formation of functional materials, e.g. through nucleation and growth from their precursors in solution or through chemically induced phase transitions. Such information is achievable though synchrotron-based in situ X-ray absorption spectroscopy (XAS) and total scattering (TS) experiments. In this study we present a new and versati
The surface chemistry of the initial growth during the first or first few precursor cycles in atomic layer deposition is decisive for how the growth proceeds later on and thus for the quality of the thin films grown. Yet, although general schemes of the surface chemistry of atomic layer deposition have been developed for many processes and precursors, in many cases, knowledge of this surface chemi
Background: Current evidence supports the use of intravenous thrombolysis with alteplase in patients with wake-up stroke selected with MRI or perfusion imaging and is recommended in clinical guidelines. However, access to advanced imaging techniques is often scarce. We aimed to determine whether thrombolytic treatment with intravenous tenecteplase given within 4·5 h of awakening improves functiona
Four decades ago, a specific engineering BSc study program in Fire Safety Engineering was formed at Lund University, Sweden, and several Nordic universities have since included courses on such subjects in their own BSc og MSc programmes. The field of fire safety engineering encompasses topics from a wide range of engineering disciplines, including mathematics, physics, chemistry and advanced engin
Purpose: To evaluate and compare which factors are relevant to the diagnostic decision-making and imaging workup of intracerebral hemorrhages in large, specialized European centers. Methods: Expert neuroradiologists from ten large, specialized centers (where endovascular stroke treatment is routinely performed) in nine European countries were selected in cooperation with the European Society of Ne
