Intrinsic Signals

Accurate interpretation of functional brain images requires knowledge of the relationship between neurons and their supporting cells and vasculature. Our understanding of this complex and dynamic system would improve if we measure multiple aspects of brain function simultaneously. We have developed a semi-transparent electrode array which allows for concurrent multi-site electrophysiological recording and high-resolution optical imaging of intrinsic signals. The 8-channel electrode array is fabricated on a transparent glass substrate with platinum recording surfaces. We map stimulus-induced field potentials (evoked potentials) and changes in cerebral blood volume in rat somatosensory cortex. We also examine the evolution of these responses during the neuro-pathological state of cortical spreading depression. We have developed a planar multi-electrode array that is fully compatible with Optical imaging of Intrinsic Signals. It provides a sensitive and reliable tool to use in the study of neurovascular coupling in brain activation.

The Many

Transparent electrodes are used widely for the many kinds of devices. The most widely used material is ITO (indium tin oxide). The attempts to improve the resistance and flexibility have been tried. The low resistance can be achieved by increasing the thickness of the ITO; however, the increase of the thickness results in the decrease of the transmittance of the incident light. Therefore,decrease of the resistance is required without increase of the thickness. We investigated the effect of the metal material on the resistance of the transparent electrode. After deposition of the metal on the ITO, we investigated the resistance of the electrode after annealing. The lowest sheet resistance was obtained for the metal Mo after 500 °C annealing. The sheet resistance 25.6 Ω/ of the ITO was decreased to 9.6 Ω/ without any significant decrease of the transmittance.

Imbalanced supercapacitor was constructed by using various ratio of activated carbon (AC) of positive to negative electrode. The electrochemical behavior of imbalanced supercapacitor was investigated using 1.0 M spiro-(1,1′)-bipyrrolidinium tetrafluoroborate electrolyte in propylene carbonate. The results showed that there are some factors that influenced the imbalanced supercapacitor with different AC ratio of positive to negative electrode, the utilization of AC, electrode potential distribution, and life cycle. The imbalanced supercapacitor with an AC weight ratio of 80 : 120 of positive to negative electrode has an average potential distribution in each electrode, and it revealed the best electrochemical performance: specific capacitor was 39.6 F·g−1, while the charge-discharge efficiency was 97.2% after 2000 life cycle tests.

ABSTRACTWe have developed a low cost and convenient approach to fabricate ITO-comparable transparent electrodes by using solution process of silver nanowires mixed with poly peroxotitanic acid (PPT) gel. The PPT gel is applied to connect the dispersed silver nanowires to preserve its high conductivity while remaining transparency and reducing surface roughness of the transparent electrode. The silver nanowires were synthesized via a modified polyol method, and the PPT gels were prepared by sol-gel method in appropriate concentrations. After applying the PPT gels, the sheet resistance of the transparent electrodes was improved from 192 Ω/□ to 44.7 Ω/□ with a transmittance of 81 %. And the roughness (RMS) was decreased from 106.3 nm to 48.1 nm. The PPT gel also improved the reliability of the proposed electrodes, which the conductivity was remained after general atmospheric storage of 6 months. We also demonstrate an Alq3 based OLED with the proposed transparent electrodes.

The distribution of electrode reactions occurring in a stress corrosion crack which is growing by enhanced anodic dissolution has been used to analytically establish the electrode potential distribution within the crack. This calculated potential distribution is discussed with reference to existing models for stress corrosion crack growth. The results of the analysis have been applied to the growth of stress corrosion cracks in a low alloy steel in 8 m sodium hydroxide solution at a temperature of 373 K.
