  1. 1. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

    University essay from KTH/Materialvetenskap

    Author : Mochen Li; [2023]
    Keywords : Photovoltaic; Molybdenum disulfide; Absorption coefficient; ab initio material design; Fotovoltaisk; Molybdendisulfid; Absorptionskoefficient; ab initio materialdesign;

    Abstract : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. READ MORE

  3. 2. Viability, feasibility and Sustainability of emission reducing solutions for Nordic wood stoves: Testing and evaluation : Degree project for Master in mechanical engineering with focus on innovative and sustainable product development

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Casper Berg; [2022]
    Keywords : Catalytic Filters; Variable filter deployment; Wood stove Emissions; Eco Design 2022; Reduced Emissions; Katalytiska filter; Varierande filter; Utsläpp från vedkaminer; Eco Design 2022; Reducerade utsläpp;

    Abstract : As of 2022 the European Union introduced a new Eco Design legislation which states emission limits for stoves sold in the EU. There are already requirements on emissions, but as both legislation are to be harder and there is a higher interest in Eco friendly products, there is an interest to study different ways to reduce the emissions from wood stoves.

  4. 3. Designing of two load bearing surfaces in a modern high-speed steam engine

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Anders Söderbäck; [2022]
    Keywords : Ranotor Modern high-speed steam engine mechanical engineering KISSsoft Bevel gears; Ranotor Ångmotor KISSsoft Maskinteknik;

    Abstract : The topic of this thesis is the designing of two load bearing surfaces in a modern high-speed steam expander. One of the surfaces is a synchronizing gear structure and the other a conical surface. The goal besides the design is to calculate the contact pressure these surfaces experience during operation.

  5. 4. Analysis of condition for ALD deposition of ferroelectric HZO

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Teodor Qvint; [2022]
    Keywords : HZO; Ferro; ALD; Temperature; Purge time; Technology and Engineering;

    Abstract : Deposition of ferroelectric hafnium zirconium oxide (HZO) on semiconductor samples with Atomic Layer Deposition (ALD) has proven to be a viable method of production. But while the physical processes of ALD deposition is relatively well know, there exists some gaps in knowledge about different parameters for the ALD and the resulting depositions. READ MORE

  6. 5. Simulating wave energy converter with twin generator torque converter in COMSOL

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Mashhur Billal; [2021]
    Keywords : Twin generator converter; dual generator; COMSOL; Savin; torque converter;

    Abstract : Uppsala University has been spending a lot of time and resources in developing wave energy converters. In the test site of Lysekil, a full-scale point absorbing buoy with its associated components have been tested. From the test, various new information were discovered. READ MORE
