The separation of hot carriers in semiconductors is of interest for applications such asthermovoltaic photodetection and third-generation photovoltaics. Semiconductor nanowiresoffer several potential advantages for effective hot-carrier separation such as: a high degree ofcontrol and flexibility in heterostructure-based band engineering, increased hot-carriertemperatures compared to bulk, and a ge
Spark ablation is an advantageous method for the generation of metallic nanoparticles with defined particle sizes and compositions. The reaction of the metal particles with the carrier gas during the synthesis and, therefore, the incorporation of those light elements into structural voids or even compound formation was confirmed for hydrides and oxides but has only been suspected to occur for nitr
The synthesis of core@shell nanoparticles has predominantly been carried out by chemical methods or physical deposition of a shell material post-growth onto core particles. By combining immiscible materials that differ in surface energy, we demonstrate the spontaneous atomic rearrangement to monodisperse Cu@Ag core@shell particles directly in the aerosol phase, starting from pure Cu and Ag electro

This workshop discusses the domestic and global aspects of China's environmental challenges. It provides insights into individual perceptions, behaviors and realities in both rural and urban China, as well as addresses different policies and government actions. The scholars pay attention to how environmental issues are related to inequalities in society, and how individuals, communities and local

A stable and convenient optical system to realize the forward phase-matching geometry for degenerate four-wave mixing (DFWM) is demonstrated in the mid-infrared spectral region by measuring DFWM signals generated in acetylene (C2H2) and hydrogen chloride (HCl) molecules by probing the fundamental ro-vibrational transitions. IR laser pulses tunable from 2900 cm(-1) to 3350 cm(-1) with a 0.025 cm(-1

This work investigates the effects of atmospheric-pressure nanosecond (ns) pulsed plasma discharges on NH3/air flames using optical emission spectroscopy (OES). Firstly, spatially-resolved OES in the 200–800 nm range of NH3/air flames with and without discharges are presented to identify the plasma-induced excited species (such as N2* and H*). Then, time-resolved OES with ns timescale resolution a
Light absorbing carbonaceous aerosols produced from combustion span over a range of physicochemical properties. Soot is the most recognized species in this category and its formation process involves gradual maturation from amorphous young soot with a high hydrogen-to-carbon-ratio toward mature soot aggregates. In this work, the optical response of a single particle soot photometer (SP2) to electr
This thesis approaches the challenges of data centre resource efficiency and global water scarcity through a techno-economic analysis of a desalination system driven by data centre waste heat. Membrane distillation is selected as a high-potential technology for this application and is examined through a case study of a hypothetical 1.5 MW direct-to-chip data centre located in Barcelona, Spain. Thr
A submerged submarine is highly sensitive to fires since the fire residues cannot be directly ventilated to the atmosphere. Deadly outcome could be the result if the submarine does not reach the surface within time or manages to purify the air while submerged. Reasons for not reaching the surface could be enemies at the surface or system failure. No Swedish submarines are today able to purify fire
Renewable diesel fuels may reduce greenhouse gas emissions and particulate matter compared to fossil diesel, but the toxicity of their combustion products remains unclear. This study assessed pulmonary effects of renewable diesel exhaust particles in female C57BL/6NTac mice after single intratracheal instillation (6, 18, or 54 µg/mouse). Particles were generated from renewable fuels (rapeseed meth
The modelling of filtered chemical source terms remains a fundamental challenges for large eddy simulation (LES) of reacting flows, such as combustion. This study investigates various scale similarity models for predicting filtered reaction rates. The theoretical foundation of scale similarity models is reviewed, and several extensions and generalisations are proposed. These include the distinctio
Popular Abstract in Swedish De mest briljanta ljuskällor som finns idag är de så kallade synkrotronljuskällorna som kan generera ljus över ett mycket brett våglängdsspectrum, från synligt ljus ända till mycket korta våglängder - röntgenstrålar. Det existerar många sådana faciliteter runt om i världen och de används dagligen i olika experiment för att öka våra kunskaper om material på en mikrospopiThere is a strong desire for short wavelength (~1 Å), short pulsewidth (<100 fs), high-brightness, transverse and longitudinally coherent light pulses for use by the synchrotron radiation community. These requirements exceed the limits achievable by existing, so-called, "third-generation" light sources, such as the Advanced Photon Source (APS) at Argonne National Laboratory (ANL), USA, the Europea
We study close encounters involving massive main-sequence stars and the evolution of the exotic products of these encounters as common-envelope systems or possible hypernova progenitors. We show that parabolic encounters between low- and high-mass stars and between two high-mass stars with small periastrons result in mergers on time-scales of a few tens of stellar free-fall times (a few tens of ho
