We investigate the material parameter requirements to fabricate efficient meta- surfaces with e-beam lithography in the NIR: minimum refractive index, minimum aspect ratio and maximum residual layer thickness values needed to reach efficiencies highe

Future energy carriers are needed in order to lower the CO2 emissions resulting from the burning of fossil fuels. One possible energy carrier is ammonia, which can be stored safely and reversibly in metal halide ammines; however, the release often oc

Metal halide ammines are very attractive materials for ammonia absorption and storage—applications where the practically accessible or usable gravimetric and volumetric storage densities are of critical importance. Here we present, that by combinin

Strontium chloride octamine, Sr(NH3)8Cl2, has been shown to be a highly efficient ammonia reservoir for selective catalytic reduction of NOx gases in vehicle exhaust and to hold great potential for indirect hydrogen storage. The possible applications

Herein we present results from experimental and theoretical studies concerning low temperature oxidation of CH4 over TiO2 supported Au nanoparticles. Our findings suggest that partial oxidation cannot be achieved under these conditions (1 bar, 30–2

Low temperature CH4 oxidation was studied on 2 nm gold nanoparticles supported on various metaloxides. The differences in reaction rates for the different systems suggest that the support material has an effect on the activity. From TEM analysis, we

We performed steady-state activity measurements in microreactors to obtain the reaction rates for CO and H 2 oxidation. These reactions were studied on three different gold particle sizes ( d ≈ 3.6 , 5.7 , 16.2 nm ) using either O 2 or N 2 O as oxi
