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

   Author : Jonas Eskhult; Leif Nyholm; Jan-Otto Carlsson; Jay Switzer; Uppsala universitet; []
   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

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

   Author : Lidong Teng; Seshadri Seetharaman; Tooru Matsumiya; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; thermodynamic activity; galvanic cell technique; transition metal carbides; transition metal nitrides; phase equilibrium; Materialvetenskap; Materials science; 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

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

   Author : Hanna Vikström; Per Högselius; Dag Avango; Fjaestad Maja; Ingulstad Mats; KTH; []
   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.; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

   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.

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

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

   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.

7. 5. Preparation and characterization of graphene/metal composites

   Author : Kristoffer Harr Martinsen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; graphene oxide; metal matrix composite; Copper; surface functionalization; anticorrosion.;

   Abstract : Since the isolation of graphene in 2004, much research has been conducted to understand this novel material and how its properties can be utilized in different applications. One type of venture involves graphene as a reinforcing filler in metal matrix composites (MMC) which is becoming increasingly prevalent in the automotive and aerospace industries. READ MORE
