  2. 1. Pool Boiling on Structured Surfaces: Heat Transfer and Critical Heat Flux : Experiments and Mechanistic Modelling

    Author : Zhen Cao; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pool boiling; heat transfer; critical heat flux; bubble dynamics; surface modification;

    Abstract : In this thesis, pool boiling heat transfer was experimentally studied on structured surfaces with dielectric liquids (HFE-7200, NOVEC-649, FC-72), organic liquids (Acetone, Pentane) and deionized water.In the first step, nanoparticle coatings on copper surfaces were prepared by an electrophoretic deposition method, with Cu-Zn nanoparticles (100 nm) and Cu nanoparticles (150 nm).

  4. 2. Food-Related Gram-Positive Bacteria: Enterotoxin A Expression in Staphylococcus aureus and a New Regulation Mechanism in Lactococcus lactis

    Author : Rong Cao; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactococcus lactis; multiple inhibition kinetics; dehydrogenase; ATP; ADP; food factors; biopreservatives; staphylococcal food poisoning; SEA; prophage induction; enterotoxin A; Staphylococcus aureus;

    Abstract : Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. READ MORE

  5. 3. Ag2S-Based Flexible Memristors for Neuromorphic Computing

    Author : Yuan Zhu; Zhen Zhang; Qing Cao; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ag2S film; flexible memristor; resistance switching; CMOS-compatible integration; neuromorphic computing;

    Abstract : Memristive crossbar arrays hold the great promise for fast and energy efficient neuromorphic computing due to their parallel data storage and processing capabilities. As the key component, memristor should achieve stable resistance switching (RS) characteristics with low energy inputs and be compatible with complementary metal–oxide–semiconductor (CMOS) technology.

  6. 4. Slag Cleaning of a Reduced Iron Silicate Slag by Settling : Influence of Process Parameters and Slag Modification on Copper Content

    Author : Jenny Isaksson; Caisa Samuelsson; Andreas Lennartsson; Anton Andersson; Pekka Taskinen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Copper losses; matte; speiss; fayalite slag; temperature; settling time; solid phases; industrial trial; CaO modification; Process Metallurgy; Processmetallurgi;

    Abstract : During the pyrometallurgical extraction of copper, a significant part of the copper is lost with discard slag, which decreases profits, overall copper recovery, and efficiency of raw material usage. Smelting furnace slag usually has a copper content that is close to or higher than that of copper ores. READ MORE

  7. 5. Settling Mechanisms of Valuable Metal Droplets in Iron Silicate Slag

    Author : Jenny Isaksson; Caisa Samuelsson; Andreas Lennartsson; Anton Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : A significant source of copper losses from pyrometallurgical copper extraction is attributed to dissolved and entrained copper in discarded slag. Entrained copper can be recovered via pyrometallurgical slag cleaning in a settling furnace where the droplets settle under gravity. READ MORE
