High-resolution pionic atom X-ray spectroscopy was performed with an X-ray spectrometer based on a 240 pixel array of superconducting transition-edge sensor (TES) microcalorimeters at the φM1 beam line of the Paul Scherrer Institute. X-rays emitted by pionic carbon via the 4f → 3d transition and the parallel 4d → 3p transition were observed with a full width at half maximum energy resolution of 6.

BACKGROUND: The current trend of upgrading undervalued agricultural by-products involves the recovery of natural antioxidants. The purpose of this study was to recover phenols from fresh olive mill wastewater (OMW) with their dispersion in 85 mL ethanol per 100 mL and to investigate the effect of processing parameters on the phenol content and antioxidant capacity of the extracts. Moreover, all th

Oil is very important for today’s society and the transportation sector is almost completely dependent on this material. Unfortunately, it affects the level of greenhouse gases negatively which in turn contribute to global warming. Therefore, it is necessary to reduce greenhouse gas emissions, especially in the sectors that emit the most, as transportation sector. The European Parliament has decid

Lower urinary tract symptoms (LUTS) can be categorized as storage, voiding, and postmicturition symptoms. Although often associated with benign prostatic hyperplasia (BPH), they may also occur in women. This observation, the beneficial effects of a-adrenoceptor (AR) antagonists in men with BPH and LUTS, and the frail correlation between LUTS, and prostatic enlargement and/or outflow obstruction ha

We investigate the target normal sheath acceleration of protons in thin aluminum targets irradiated at a relativistic intensity by two time-separated ultrashort (35 fs) laser pulses. When the full-energy laser pulse is temporally split into two identical half-energy pulses, and using target thicknesses of 3 and 6 μm, we observe experimentally that the second half-pulse boosts the maximum energy an

The open-circuit voltage (Voc) of all-polymer solar cells (all-PSCs) is typically lower than 0.9 V even for the most efficient ones. Large energy loss is the main reason for limiting Voc and efficiency of all-PSCs. Herein, through materials design using electron deficient building blocks based on bithiophene imides, the lowest unoccupied molecular orbital (LUMO) energy levels of polymer acceptors

Laman Magsudlu MSc in Strategic Communication, AzerbaijanParticipating in the Career Programme is a truly valuable experience. During our visit to Nederman, one phrase particularly resonated with me: 'We value people, not titles.' I think, it perfectly captured the essence of Swedish corporate culture. The in-depth presentations and open Q&A sessions gave us a clear understanding of how companies

Associate senior lecturer My recent research has focused on the structure and photoluminescence of assemblies (superlattices) of lead halide perovskite nanocrystals. In Lund, I aim to understand and control the cooperative properties of nanocrystals with the help of materials engineering, laser spectroscopy, and theory.

The microorganism Cupriavidus necator is a very interesting bacterium that has been established as a model microorganism for its capability to produce polyhydroxyalkanoates, more specifically polyhydroxybutyrate (PHB), a potential precursor/raw material for bioplastics. Lately, the scientific community has raised interest in the chemolithoautotrophic nature of C. necator as it can be grown using C

Denna rapport utforskar konceptet undvikna utsläpp, även kallat Scope 4-utsläpp, som en del av företags hållbarhetsrapportering- och kommunikation. Med fokus på PowerCell Group, en leverantör av vätgasdrivna bränsleceller, undersöker studien hur Scope 4-utsläpp kan integreras i hållbarhetsrapportering och vilka möjligheter och utmaningar detta innebär. Undvikna utsläpp refererar till de minskningThis thesis explores the concept of Scope 4 emissions, also known as avoided emissions, within corporate sustainability reporting. With a focus on PowerCell Group, a provider of hydrogen fuel cell solutions, this study investigates the integration of avoided emissions reporting, assessing both the potential benefits and the challenges associated with this practice. Avoided emissions refer to redu

Hydrogen (H2) and methanol (MeOH) are promising fuels for sustainable transport, owing to their ideal properties for use in internal combustion engines: CO2 neutral (when produced renewably), ultralow emissions, and high efficiencies. The dual-fuel (DF) technology where diesel is used as a pilot to ignite port fuel injected H2 or MeOH is of particular interest for retrofitting existing diesel engi

Lytic polysaccharide monooxygenases (LPMOs) are surface-active redox enzymes that catalyze the degradation of recalcitrant polysaccharides, making them important tools for energy production from renewable sources. In addition, LPMOs are important virulence factors for fungi, bacteria, and viruses. However, many knowledge gaps still exist regarding their catalytic mechanism and interaction with the

Second coordination sphere interactions of cyanido complexes with hydrogen-bonding solvents and Lewis acids are known to influence their electronic structures, whereby the non-labile attachment of B(C6F5)3resulted in several particularly interesting new compounds lately. Here, we investigate the effects of borylation on the properties of two FeIIcyanido complexes in a systematic manner by comparin

The metalorganic chemical vapor deposition (MOCVD) dynamics of beta-gallium oxide (β-Ga2O3) growth using trimethylgallium (TMGa) and oxygen as precursors were investigated through both theoretical thermodynamic analysis and experimental validation in a horizontal low-pressure hot-wall reactor. Thermodynamic analysis revealed that high-purity β-Ga2O3 can be grown through the complete combustion of

Centrifugal compressors are widely used in turbocharged powertrains for Heavy-Duty applications. The volute of the centrifugal compressors is generally of the overhung type. The design of volutes is often neglected, and the shape of the volute is dictated by the packaging requirements of the engine. However, with the advent of Hydrogen-based propulsion systems, the efficiency of all the components

The reactivity of six MnIV-oxo complexes in C-H bond oxidation has been examined using a combination of kinetic experiments and computational methods. Variable-temperature studies of the oxidation of 9,10-dihydroanthracene (DHA) and ethylbenzene by these MnIV-oxo complexes yielded activation parameters suitable for evaluating electronic structure computations. Complementary kinetic experiments of
