3. 17. Corrosion-induced release of zinc and copper in marine environments

   Författare :Jan Sandberg; Inger Odnevall Wallinder; Dan Persason; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copper; zinc; marine environment; runoff rate; atmospheric corrosion; chloride deposition; anti-fouling paints; chemical speciation; bioavailability; cupric ions; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : This licentiate study was initiated by copper, zinc and galvanized steel producers in Europe, who felt a need to assess runoff rates of copper and zinc from the pure metals and commercial products at marine exposure conditions. Their motive was the increasing concern in various European countries and the on-going risk assessments of copper and zinc within the European commission. LÄS MER

4. 18. Micro-galvanic effects and corrosion inhibition of copper-zinc alloys

   Författare :Mattias Forslund; Jinshan Pan; Christofer Leygraf; Per Claesson; Jin Ying; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Copper; zinc; brass; octadecanethiol; IR Spectroscopy; AFM; atmospheric corrosion; aqueous corrosion; corrosion inhibition; Koppar; zink; mässing; oktadekantiol; IR-reflektions absorptionsspektroskopi; AFM; atmosfärisk korrosion; vattenaktig korrosion; korrosionsinhibering.; Chemical Engineering; Kemiteknik; Kemi; Chemistry;

   Sammanfattning :    With the advancement and accessibility of local probing techniques that can operate at the submicron scale it has become possible to analyse the local corrosion properties of industrially important metallic materials and relate these properties to microstructure characteristics of the same materials. In this doctoral study the focus has been on copper-zinc samples, both as industrial brass alloys and as micro-patterned copper-zinc samples. LÄS MER

5. 19. Prussian blue analogue copper hexacyanoferrate : Synthesis, structure characterization and its applications as battery electrode and CO2 adsorbent

   Författare :Dickson Odhiambo Ojwang; Gunnar Svensson; Jekabs Grins; Andrew Goodwin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; copper hexacyanoferrate; synthesis; structure refinement; thermal dehydration; CO2 adsorption; kinetic analysis; in operando synchrotron X-ray diffraction; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Prussian blue (PB) and Prussian blue analogues (PBAs) are compounds with potential applications in a large variety of fields such as gas storage, poison antidotes, electrochromism, electrochemistry and molecular magnets. The compounds are easy to synthesize, cheap, environmentally friendly and have been pursued for both fundamental research and industrial purposes. LÄS MER

7. 20. COPPER BINDING PROTEINS IN BREAST CANCER : CELLULAR AND MOLECULAR MECHANISMS

   Författare :Xiaolu Zhang; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atox1; Memo1; cell migration; breast cancer; copper; ROS;

   Sammanfattning : Cancer is one of the leading causes of human death. However, the mechanisms governing cancer are still not fully understood. Elevated levels of copper (Cu) have been observed in both cancerous tissues and the serum of cancer patients. LÄS MER
