Fabrication of Carbon Nanotube/Indium Tin Oxide "Inverse Tandem" Absorbing Coatings with Tunable Spectral Selectivity for Solar-Thermal Applications. Energy Technol. (Weinheim, Ger.)Energy Technology (Weinheim, Germany). 2015;3 (10) :1045 - 1050.Abstract
We report the fabrication of a new selective "inverse tandem" absorbing coating based on carbon nanotube (CNT)/indium-tin oxide (ITO) on aluminum (Al) for mid-temp. solar-thermal application. The CNT layer is formed by spraying and functions as an excellent solar absorber whereas the ITO layer produced on top of the CNTs by sputtering serves as an IR reflector. The effect of the thickness of the ITO on the spectral selectivity of the absorbing coating was investigated. Controlling the thickness of ITO allowed the spectral selectivity of the coating to be tuned. The CNT/ITO solar coatings with optimized thickness of ITO showed excellent spectral selectivity values of absorptance (α) of 0.927 and emittance (ε) of 0.2. The performance of the coatings at high temp. after heating in air in the range of 25-300°C for different durations was also investigated. The performance and structure of the CNT/ITO coating was also compared with the wet deposition method in which the ITO coating was formed by spraying. [on SciFinder(R)]

The electrochem. redn. of indium tin oxide (ITO) on glass is systematically studied. The light absorbance and elec. resistance of ITO increases upon redn. SEM images show that the integrate ITO films dissolve and form particles upon applying neg. potentials. The particles consist of metallic In and Sn, as characterized by XRD and XPS. The redn. of ITO strongly depends on the electrolyte conditions, mainly pH and anions. The onset potential is found to shift neg. as the pH of the electrolyte increases. NO-3 ions significantly inhibit the redn. of ITO, shifting the redn. potential neg. by ∼500 mV as compared with SO2-4, Cl- and Br-. It can also serve as inhibitor by adding very low concn. to the Cl--dominant electrolyte. Also, the electrochem. reduced ITO show excellent nonlinear optical performance, with transmittance tuneable by redn. potential and time. This suggests a promising useful application of the electrochem. redn. of ITO. [on SciFinder(R)]

A sensitive electrochemical DNA biosensor based on the amplification of Au nanoparticles (AuNPs) has been developed. The AuNPs were modified with two types of signaling reporter DNAs, i.e. a methylene blue probe (MB-probe 2-SH) and T10 with a methylene blue signaling molecule (MB-T10-SH), forming DNA-AuNP conjugates. The MB-probe 2-SH is complementary to the target DNA, while MB-T10-SH is not. The presence of MB-T10-SH reduces the cross-reaction between target DNA and MB-probe 2-SH on the AuNPs, resulting in increased sensitivity of the biosensor. In our assay, the DNA sensor is fabricated by immobilizing a capture probe on the surface of the Au electrode, which then hybridizes with the corresponding target DNA, and further hybridizes with a DNA-Au conjugate. The signal of MB is measured by differential pulse voltammetry, while the DNA-Au conjugate enables the detection of target DNA in the linear range of 10(-13) to 10(-8) M with the detection limit as low as 50 fM.[on SciFinder (R)]

A novel approach of patterning graphene on conductive surfaces based on local electrochemical reduction of graphene oxide is reported. Graphene is "written" from typical graphene oxide dispersion by applying negative potential on conductive surfaces vs. a micrometer-sized counter electrode "pen" with scanning electrochemical microscopy (SECM). Micrometer scaled patterns are successfully generated on gold and stainless steel surfaces.[on SciFinder (R)]
