CaO Nanoparticles Coated by ZrO2 Layers for Enhanced CO2 Capture Stability

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1281976

CaO is an attractive CO2 acceptor, due to its good kinetics and high capture capacity, even under low CO2 concentration conditions. The major problem associated with CaO acceptors is the loss of CO2 capture capacity during cyclic operations. The declining performance of the CaO acceptors is more pro...

Combined X-ray and Raman studies on the effect of cobalt additives on the decomposition of magnesium borohydride

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1300601

Magnesium borohydride (Mg(BH4)2) is one of the most promising hydrogen storage materials. Its kinetics of hydrogen desorption, reversibility, and complex reaction pathways during decomposition and rehydrogenation, however, present a challenge, which has been often addressed by using transition metal...

Titanium uptake and incorporation into silica nanostructures by the diatom Pinnularia sp. (Bacillariophyceae)

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1149434

Diatoms are an ecologically successful group within the phytoplankton, and their special feature is a biofabricated silica cell encasement called a frustule. These frustules attract interest in material technology, and one potential application is to use them in solar cell technology. The silica fru...

One-step electrochemical synthesis of tunable nitrogen-doped graphene

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1308440

A one-step electrochemical approach for the production of tunable nitrogen-doped graphene has been developed in this work. The simultaneous production and nitrogen incorporation of graphene are realized by electrochemical exfoliation of graphite in an aqueous electrolyte containing (NH4)2SO4 and NH3...

ZnO-Carbon-Nanotube Composite Supported Nickel Catalysts for Selective Conversion of Cellulose into Vicinal Diols

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1282169

A ZnO-nanolayer-coated carbon nanotube (CNT) composite (ZnO–CNT) was employed as a support to immobilise Ni catalysts. Well-mixed oxides, formed as a result of enhanced interfaces between the two oxides on CNTs, resulted in the formation of Ni–Zn alloys in reduced catalysts. The Ni/ZnO–CNT catalyst ...
