1. The active phase of Pt(110) during catalytic CO oxidation
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. READ MORE

2. Acoustic Characterization of Catalyst
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. READ MORE

4. Tribological Performance of Novel Boron Dithiocarbamate Lubricant Additives
University essay fromAbstract : Different lubricant additives such as dialkyldithiophosphates (DTPs) of different metals have been extensively used as multifunctional additives to control wear and friction in mechanical systems. These additives can produce protective films on steel rubbing surfaces and, therefore, control friction and reduce wear. READ MORE

5. Defects in ceria
University essay from Institutionen för fysik, kemi och biologiAbstract : The solid oxide fuel cell (SOFC) technology has been under research since thelate 1950s, and most of the research has been on designs utilizing yttria stabilized zirconia (YSZ) as the electrolyte of choice. However, the SOFC technology has the major drawback of requiring high operation temperatures (up to 1000 degrees Celcius), so research of alternative materials have come into interest that would possibly require a lower working temperature without any significant loss of conductivity.
