2. 1. Influence of hydrogen on corrosion and stress induced cracking of stainless steel

   Author : Ulf Kivisäkk; Christofer Leygraf; Roy Johnsen; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen; corrosion; hydrogen embrittlement; stainless steels; uniform corrosion; activation; dewpoint corrosion; low temperature creep; plastic deformation; microhardness; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : Hydrogen is the smallest element in the periodical table. It has been shown in several studies that hydrogen has a large influence on the corrosion and cracking behaviour of stainless steels. Hydrogen is involved in several of the most common cathode reactions during corrosion and can also cause embrittlement in many stainless steels. READ MORE

4. 2. Intermolecular interactions in hydrogen bonded 1:1 molecular complexes. A matrix isolation study

   Author : Anders Engdahl; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; infrared laser irradiation; dimethyl ether; water dimer; hydrogen chloride; formamide; acetone; formic acid; ammonia; water; intermolecular; matrix isolation; FIR; FTIR; infrared; isomerisation; ab initio; Physical chemistry; Fysikalisk kemi;

   Abstract : A number of matrix isolated binary hydrogen bonded complexes with water as one of the components have been investigated with FTIR in the mid and far infrared regions. Water has been found to be the hydrogen bond donor in complexes with water, ammonia, dimethyl ether and acetone. READ MORE

5. 3. Chloride-based Silicon Carbide CVD

   Author : Henrik Pedersen; Erik Janzén; Anne Henry; Yaroslav Koshka; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

   Abstract : Silicon carbide (SiC) is a promising material for high power and high frequency devices due to its wide bandgap, high break down field and high thermal conductivity. The most established technique for growth ofepitaxial layers of SiC is chemical vapor deposition (CVD) at around 1550 °C using silane, SiH4, and lighthydrocarbons e g propane, C3H8, or ethylene, C2H4, as precursors heavily diluted in hydrogen.

6. 4. Influence of the electrolyte on the electrode reactions in the chlorate process

   Author : Linda Nylén; Göran Lindbergh; Ann Cornell; Mårten Behm; Geoeff H Kelsall; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chlorate; chloride oxidation; critical anode potential; chromate; DSA; hydrogen evolution; iron; mass transport; oxygen evolution; REM; RDE; steel; Electrochemistry; Elektrokemi;

   Abstract : The chlorate process is very energy intensive and a major part of the production costs are for electrical energy. Since the electricity prices are constantly increasing and may also vary periodically, the chlorate plants may be forced to adjust their production rate to the price at each moment in order to minimise their costs.

7. 5. Initiation and Repassivation of Pits on Austenitic Stainless Steel

   Author : Fredrik Falkenberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chloro complex; pitting corrosion; metastable pits; phosphate; nitrogen; passive film; chloride; repassivation; molybdenum; austenitic stainless steel;

   Abstract : Stainless steels can be damaged by pitting corrosion in presence of aggressive anions, such as halide ions. The aim of this work was to study different aspects on initiation and repassivation of pits on austenitic stainless steel in chloride solutions at ambient temperature. READ MORE
