  1. 1. Studies on Radiation-induced Defects in InP/InAsP Nanowire-based Quantum Disc-in wire Photodetectors

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Ebrahim Mansouri; [2018]
    Keywords : InP InAsP; QDiscs-in-wire; photodetectors; proton irradiation; Photocurrent; I-V characteristics;

    Abstract : Photodetectors are used in many applications such as digital and thermal cameras or in solar panels. They can also be designed to detect the omnipresent high-energy radiation/particles, and for radiation imaging in biomedical applications. READ MORE

  3. 3. Corrosion initiation induced by sodium sulfate and sodium chloride particles on Cu and the golden alloy Cu5Al5Zn at simulated atmospheric conditions

    University essay from KTH/Materialvetenskap

    Author : WEIJIE ZHAO; [2017]
    Keywords : atmospheric corrosion; sodium sulfate; sodium chloride; Cu5Al5Zn; Cu metal; mixed salt pre-deposition; laboratory exposure; LOM; SEM EDS; ATR-FTIR; cathodic reduction;

    Abstract : Effects of sodium sulfate (Na2SO4) particle deposition on the atmospheric corrosion of copper (Cu) metal and a Cu-based alloy (Cu5Al5Zn) used in architectural applications were investigated at laboratory conditions compared with effects induced by sodium chloride (NaCl) and to some extent ammonium sulfate (NH4)2SO4 induced corrosion. Pre-deposited surfaces were exposed to repeated wet/dry conditions in a climatic chamber and the formation of corrosion products were assessed using light optical microscopy (LOM), scanning electron microscopy with elemental analysis (SEM/EDS), Fourier transform infrared techniques (FTIR microscopy) and cathodic reduction (CR).

  4. 4. Evaluation of Esterification as a Valorization Route for Oxidized Lignin

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Johanna Lindmark; [2017]
    Keywords : Lignin; Kraft Lignin; Esterification; Peracetic Acid; Oxidized Lignin; Muconic Acid; Vanillic Acid;

    Abstract : RISE Bioeconomy is working with the biorefinery concept. That is, for the company, to utilize all wood derivatives in effective processes, resulting in unique products. RISE Bioeconomy is investigating the possibilities of producing holocellulose through an oxidative delignification process of wood, using peracetic acid (PAA). READ MORE

  5. 5. Lake condition changes of a boreal lake over the past ca. 6500 years based on varve geochemistry

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Jora Ligtenberg; [2017]
    Keywords : varved lake sediment; total element concentrations; biogenic silica; lake-water organic carbon; Holocene;

    Abstract : The purpose of this study was to assess changes in the in-lake conditions of lake Kassjön, northern Sweden, in response to environmental and climate changes over the past ca. 6500 years. READ MORE
