In contrast to a bare oxide catalyst, metal loading catalysts showed higher activities and efficiencies for the reaction.
The effect of a reduction pre-treatment at 350 °C on the catalytic performance of both, the platinum catalyst and the bare oxide was studied.
The bare oxide surface was covered with a confluent layer of organisms, making enumeration impractical.
In a separate 72-hour growth experiment with oxidized Ti-6Al-4V alloy, PEG 375 -acrylate coated alloy, and VPEG 375 -acrylate-acoatede coalloyandoy, the bare oxide surface was completely coVPA 3400 -PEG 375 -acrylates and glycocalyx (Fig. 5A–B).
Consistent with previous studies, band-gap excitation of the catalyst-loaded TiO2 showed smaller signal amplitudes and faster decays for photoexcited electrons compared to the bare metal oxides (Fig. 3).
Here, we report on adhesive interactions between diamond indenters and monolayer, bilayer and trilayer graphene on silicon oxide as well as bare silicon oxide and graphite over relatively small spatial domains.
The bonding status of carbon on the surfaces of the nanoparticles was checked using the wavelength-dependent transmittance data obtained using an FTIR spectrometer (Nicolet 380, Thermo Scientific, Waltham, MA, USA). Figure 3a, b shows the FTIR spectra for bare iron oxide and carbon-coated iron oxide nanoparticles, respectively.
The band at 2,920 cm-1 resulted from the stretching vibrations of O-H. Figure 3 FTIR spectra for bare iron oxide (a) and carbon-coated iron oxide (b) nanoparticles, respectively.
Hydrophilic carbon coating on iron oxide nanoparticle cores endows better dispersibility and stability than those shown by bare iron oxide nanoparticles.
Galvanostatic charge and discharge results indicate that the nickel-oxide film with monodispersed open macropores is capable of delivering a higher capacity than the bare nickel-oxide film, especially in high-rate charge and discharge processes.
