  1. 1. Electrochemical Deposition of Nanostructured Metal/Metal-Oxide Coatings

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Eskhult; Uppsala universitet.; [2007]
    Keywords : Inorganic chemistry; electrochemical deposition; local pH; Cu2O; Sb2O3; complex; EQCM; reduction; Oorganisk kemi;

    Abstract : Electrochemical deposition finds applications in the electronics- and protective coating industries. The technique is a versatile tool for the synthesis of alloys and thin films. Knowledge of the fundamental aspects of the electrode processes enables the design of nanostructured materials. READ MORE

  2. 2. Thermodynamic investigations of transition metal systems containing coabon and nitrogen

    University dissertation from Materialvetenskap

    Author : Lidong Teng; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; thermodynamic activity; galvanic cell technique; transition metal carbides; transition metal nitrides; phase equilibrium; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : In view of the important applications of carbides and carbo-nitrides of transition metals in the heat-resistant and hard materials industries, the thermodynamic activities of Cr and Mn in the Cr-C, Fe-Cr-C, Mn-Ni-C and Mn-Ni-C-N systems have been studied in the present work by the use of the galvanic cell technique. CaF2single crystals were used as the solid electrolyte. READ MORE

  3. 3. The Specter of Scarcity Experiencing and Coping with Metal Shortages, 1870-2015

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hanna Vikström; KTH.; [2017]
    Keywords : HUMANIORA; HUMANITIES; scarcity; critical metals; Sweden; small countries; strategic metals; metal shortages; history of technology; experiences of scarcity; coping with shortages; technological trends; World War I; resource crisis; construction of resources.; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

    Abstract : In spite of an ever-growing supply of metals, actors have long feared metal shortages. This thesis – departing from an understanding that metals scarcity is not an objective geological fact, but an experience, a fear of a shortage – explores why business and state actors have experienced metals as scarce and how they coped with scarcity from 1870 to 2015.

  4. 4. Heavy metal removal by floating treatment wetlands: Plant selection

    University dissertation from Stockholm : Stockholm University

    Author : Maria Schück; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phytoremediation; Rhizofiltration; Heavy metal; Chloride; Floating treatment wetland; Wetland plants; Stormwater; växtfysiologi; Plant Physiology;

    Abstract : Elevated levels of heavy metals and chloride are commonly found in stormwater, as a consequence of pollution from traffic, building material and industries, and the use of salt for deicing in wintertime. Floating treatment wetlands (FTWs), consisting of vegetated rafts that can be placed in stormwater ponds, may be able to reduce heavy metal and chloride concentrations, but until this date have mainly been used for nutrient removal in warm climates.

  5. 5. Safety Politics and Risk Perceptions in Malaysian Industry

    University dissertation from Department of Sociology, Lund University

    Author : Arne Wangel; [1997]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Malaysia; metal industries; manufacturing sector; working environment; safety politics; risk perceptions; occupational safety and health; labour process; labour-management relations; Sociology of work; industrial relations; South-East Asia; Sociology of labour; sociology of enterprise; Arbetslivssociologi; företagssociologi;

    Abstract : The thesis concerns risk and safety in manufacturing companies in a developing country. Risk and safety is viewed as integral to the social relations between management and labour. The Malaysian case presents a historical conjuncture of this conflict theme, which is very different from that of its Western genesis. READ MORE
