1. 16. γ-Radiation Induced Synthesis of Metal oxides : Control of Particle Size, Composition, and Morphology

   Författare :Zhuofeng Li; Mats Jonsson; Hynd Remita; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; γ-radiation induced synthesis; Metal oxide nanoparticles; Metal oxide nucleation; Mesocrystal formation; Carbon black reactivity towards radical; PVP nanogel.;

   Sammanfattning : Nanomaterials show a significant difference in chemical, mechanical, electronic, magnetic and optical properties compared with bulk counterparts. The synthesis is a key-step to achieve the unique properties of nanomaterials. LÄS MER

3. 17. Effects of biocides and metals on antibiotic resistance: a genomic and metagenomic perspective

   Författare :Chandan Pal; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; biocide; metal; co-selection; metagenomics;

   Sammanfattning : Background and aim: There is a concern that biocides and metals can co-select for antibiotic resistance. The aim of this thesis is to enhance our understanding of the roles of antibacterial biocides (e.g. antiseptics, disinfectants) and metals (e. LÄS MER

4. 18. Modelling the Molecular World of Electrolytes and Interfaces : Delving into Li-Metal Batteries

   Författare :Mahsa Ebadi; Daniel Brandell; Tejs Vegge; Uppsala universitet; []
   Nyckelord :Li-metal battery; solid polymer electrolyte; density functional theory; molecular dynamics simulation; solid electrolyte interphase;

   Sammanfattning : Lithium metal batteries (LMBs) are potential candidates for powering portable electronic devices and for electromobility. However, utilizing the reactive Li metal electrode means tackling serious challenges in terms of safety risks. LÄS MER

5. 19. FE-Simulation of Metal Cutting Processes

   Författare :Ahmet Semih Ertürk; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inverse identification; Machine learning; Metal cutting; Finite element method; Heat transfer; Machining;

   Sammanfattning : Machining a new component or a new material requires the selection of the cutting conditions, the tool material and the tool geometry. The selections should be also optimized for the existing components and materials to improve the quality of the produced components and reduce the cost of production. LÄS MER

7. 20. Modeling framework for ageing of low alloy steel

   Författare :Magnus Boåsen; Pål Efsing; Jonas Faleskog; Carl F. O. Dahlberg; Christian Niordson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low alloy steel; length scale effects; size effects; plasticity; cleavage fracture; brittle fracture; weakest link; ageing; weld metal; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Ageing of low alloy steel in nuclear applications commonly takes the form as a hardening and an embrittlement of the material. This is due to the evolution of the microstructure during irradiation and at purely thermal conditions, as a combination or separate. LÄS MER
