We study the electronic structure and chemical bonding of the SO2 molecule adsorbed on Ni(100) surface using x-ray emission spectroscopy at the O1s absorption edge. Elemental and symmetry specificities of the method enable us to directly probe surface chemical bonding formed by strong hybridization of O2p with Ni3d orbital. Contrary to the expected π bonding due to strong π acceptor character of t

We successfully synthesized a hetero face-to-face porphyrin array composed of ZnTPP and RuTPP(DABCO)2 (TPP: 5, 10, 15, 20-tetraphenylporphyrin, DABCO: 1,4-diazabi-cyclo[2.2.2]octane) in 2:1 molar ratio. A cyclic Zn porphyrin dimer (ZnCP) was also used as the host molecule for the Ru porphyrin. In the latter, the Ru-DABCO bonding in RuTPP(DABCO)2 was stabilized by the host-guest complexation. React

Komplex produktutveckling med långa projekttider kräver framgångsrik överföring av kunskap inom och mellan projekt. Avdelningen för integrerat logistikstöd (ILS) vid Saab Kockums Malmö har identifierat ett behov av att överskåda de nuvarande arbetssätten. Syftet med detta examensarbete är att undersöka de olika typerna av kunskap som är viktiga för arbetet på ILS-avdelningen, undersöka avdelningenComplex product development with long project times requires successful transfers of knowledge within and between projects. The department of integrated logistics support (ILS) at Saab Kockums Malmö has identified a need to oversee the current working methods. The purpose of this master thesis is to examine the different types of knowledge important to the work at the ILS department and explore th

This thesis aims to find a design suggestion for the chassis of a new micromobility vehicle developed by the company LEVTEK SWEDEN AB by using a multiple load, compliance based topology optimization. For this purpose, 9 static load cases are suggested, 4 of which have been derived from dynamic scenarios using an equivalent static load inspired approach based on free-body diagrams. The results from

Currently studies aiming for the comprehensive metabolomics profiling of measured total fat (%) as well as fat distribution in both sexes are lacking. In this work, bioimpedance analysis was applied to measure total fat (%) and fat distribution (trunk to leg ratio). Liquid chromatography-mass spectrometry-based untargeted metabolomics was employed to profile the metabolic signatures of total fat (

The automotive industry is currently undergoing significant transformation to mitigate greenhouse gas emissions as sustainability emerges as a global imperative. While electrification reduces tailpipe emissions, adopting principles of circularity throughout the entire value chain enables further reductions. The research aims to investigate the feasibility of increasing recycled content in bearing

This paper investigates what can promote green energy projects on land which consist of solar and wind power. The research is done with an economic geographic framework of path-development. A paradigmatic case study is conducted with scientific semi-structured interviews and short “pop-up interviews” which validated the in-depth interviews. These pop-up interviews also highlight further points and

Titel: Från plast till hållbarhet - Svenska lågprisföretag inom skönhetsbranschen tar ställning: En kvalitativ studie om svenska lågprisföretags hållbarhetsarbete och hållbarhetskommunikation inom skönhetsbranschen Författare: Carolina Vanhollebeke och Siri Björklund Universitet: Lunds Universitet, Institutionen för Tjänstevetenskap. KSMK65, Examensarbete för kandidatexamen. Vårterminen 2023. Ha

Purpose: Although past studies have found well-constrained soil carbon (C)/nutrient ratios, the effects of increased nitrogen (N) and water inputs on these ratios across soil depths have rarely been assessed in semi-arid grasslands. Methods: In this study, we evaluated the contents of total C, N, phosphorus (P), sulfur (S), and their stoichiometric ratios in a 0–80 cm soil profile following 13 yea

Preening behaviours are widespread in extant birds. While most birds appear to autopreen (self-directed preening), allopreening (preening directed at conspecifics) seems to have emerged only in certain species, but across many families. Allopreening has been hypothesised to reinforce mutual relationships and cooperation between individuals, and to underpin various socio-cognitive abilities. Palaeo

BackgroundPatients with chronic right ventricular (RV) pacing are at an increased risk of heart failure. Previous studies have indicated that cardiac resynchronization therapy (CRT) is underused in this setting, and that there may be sex-based differences in both CRT use and clinical outcome.ObjectiveTo evaluate sex-based differences in CRT use and clinical outcome for patients with new-onset hear

The sixth volume in the Interdisciplinary European Studies assesses the changes that are taking place in the EU’s policies, institutions, and political structures. On the eve of a new chapter of European integration in the dark shadow of the war in Ukraine, it is high time to assess the changes that have taken place in recent time and consider whether current developments are taking the EU on the

2D van der Waals (vdW) antiferromagnets have received intensive attention due to their terahertz resonance, multilevel magnetic-order states, and ultrafast spin dynamics. However, accurately identifying their magnetic configuration still remains a challenge owing to the lack of net magnetization and insensitivity to external fields. In this work, the Néel-type antiferromagnetic (AFM) order in 2D a

The main purpose of this thesis is to prove the Bieberbach inequality using Grönwall’s area theorem, and discuss some consequences of the Montel’s theorem and Carathéodroty convergence theorem regarding single-slit maps, which is essential to the proof of de Branges’ theorem.

Background and Objective: Immobilization of enzymes as cross-linked aggregates is one of the cheapest, simplest and effective techniques for improving their stability and reusability and even avoiding contamination of the product with the catalyst. Clopidogrel is a widely used antiplatelet drug, only Sisomer is the biologically active enantiomer produced by resolution of the racemic compound. In t
