Nanowire (NW) Photovoltaics are a promising route for low-cost multi-bandgap tandem cells, which is taxing in terms of processing and lattice matching in traditional planar geometries.[1] III-V nanowires are more suitable for monolithic integration as they can assimilate the lattice mismatch to a larger extent.[2] GaAsP is a material that offers a wide tunability of the band gap from near infrared
Thin organic coatings (TOC) or paints on hot dip galvanized steel (HDGS) improve the corrosion properties and create visually pleasing surfaces. Delamination of these coatings leads to corrosion and peeling of the paints. Hence, a novel method for improved adhesion and corrosion properties for HDGS surfaces is introduced. It is shown how the fabrication of a nanomolecular silane film as an interfa
Generally, low temperatures are favourable for district heating (DH) systems, while several factors limit how low temperatures can actually be. The history of DH is characterized by a constant strive for lower temperatures. In order to stay competitive, and increase its market share, the DH industry must continue the work towards even lower temperatures. This chapter goes through the impressive re
Magnetic nanoparticles have shown great potential for use in drug delivery and bioimaging applications and are prospective building blocks in future high-performing permanent magnets. Today, magnetic nanoparticles are most often produced in batches by chemical methods resulting in the risk of chemical impurities and production of vast amounts of chemical waste. Aerosol generation methods on the ot
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
Nanoparticle superlattices consisting of densely packed particles with periodic arrangements can exhibit interesting collective properties different from those of individual nanoparticles and thus have attracted great interest in research due to their potential applications in optoelectronic, plasmonic, and magnetic devices. Evaporation-induced self-assembly on solid substrates which employs nanop
We present the synthesis of monodisperse aerosol InSb nanoparticles of high crystalline quality using the spark discharge generation (SDG) method. Apart from successfully using metallic In and Sb electrodes, we demonstrate the feasibility of using pure semiconducting InSb wafers as electrode material. We investigated the influence of carrier gas on the quality of the size selected particles. We sh
Background: The use of in vitro cell cultures is a powerful tool for obtaining key insights into the behaviour and response of cells to interventions in normal and disease situations. Unlike in vivo settings, in vitro experiments allow a fine-tuned control of a range of microenvironmental elements independently within an isolated setting. The recent expansion in the use of three-dimensional (3D) i
Since the Oslo Accords, the two-state solution has dominated, and frustrated, the official search for peace in Palestine/Israel. In parallel to it, an alternative struggle of resistance—centred upon the single-state idea as a more liberating pathway towards justice to the conflict—has re-emerged against the hegemony of Zionism and the demise of a viable two-state solution in Palestine/Israel. This
In this chapter I begin by giving a brief snapshot of the recent re-emer- gence of the single-state solution as a potential political force, and of its alternative intellectual worldview against the Oslo Accords. Predominantly powered forward by the Palestinian Diaspora within the international arena today, it is this unified vision that holds the whole of the alternative together as a movement of
Providing the first in-depth intellectual and organizational mapping of the single state idea’s recent resurgence in Palestine/Israel, this book enquires into its nature as a phenomenon of resistance, as well as into its potential as a counterhegemonic force in the making against the processes of Zionism.Reconstructing this moment of re-emergence through primary material and interviews with divers
Endoscopic resection of colorectal polyps reduce morbidity and mortality from colorectal cancer (CRC).Endoscopic submucosal dissection (ESD) is a highly efficient and established method for treating advanced colorectal lesions in Asia, but experience of ESD in Western countries is limited. Large non-pedunculated colorectal lesions are prone to malignant transformation and it is therefore important
Background and study aimsEndoscopic submucosal dissection (ESD) is an established method for en bloc resection of large non-pedunculated colorectal lesions in Asia but dissemination of ESD in Western countries is limited. The aim of this study was to evaluate the role of ESD in the management of malignant non-pedunculated colorectal lesions in a European center.Patients and methods Among 255 patie
This dissertation is a study in empirical macroeconomic history. The first two papers concern themselves with the functional distribution of income. The third paper is an examination of global real interest rates, and the final paper examines city growth in Sweden over the last two hundred years. While this thesis is not about secular stagnation per se, every articles is related in one way or the
In October 2010 new recommendations were issued in Sweden concerningthe treatment of acute otitis media (AOM). Watchful waiting is recommendedfor otherwise healthy children aged 1-12 years with uncomplicated AOM. In allpatients with complicating circumstances and all patients under the age of 1 yearand over the age of 12 years (including adults) antibiotic treatment of AOM isrecommended. In the gu
Objective: To summarize recently published key articles on the topics of biomedical engineering, biotechnology and new models in relation to otitis media (OM). Data sources: Electronic databases: PubMed, Ovid Medline, Cochrane Library and Clinical Evidence (BMJ Publishing). Review methods: Articles on biomedical engineering, biotechnology, material science, mechanical and animal models in OM publi
IntroductionNasopharyngeal cultures are commonly used to determine the causative bacteria in upper airway infections. However, several bacteria can occupy the nasopharynx simultaneously and most healthy children are asymptomatic carriers of presumptive pathogens. This makes the interpretation of nasopharyngeal cultures difficult. Knowledge about which bacteria reside in the nasopharynx can assist
