Long Lifetime

In order to develop long-lifetime neural electrodes, the insertion tissue injury caused by two optimized neural electrode (convex streamline electrode and vibration attenuation electrode) models were evaluated compared with a reference electrode. Based on the experimental evaluation system for testing tissue injury, the effects of insertion speeds on tissue injury of the two optimized electrodes with different insertion depths were studied. The maximum tissue strain caused by the two optimized neural electrodes firstly increased and then decreased with the increase of insertion speed at the depths of 3 mm and 4.5 mm. The insertion forces caused by vibration attenuation electrode are steady with the change of insertion speed. The convex streamline neural electrode caused less tissue injury compared with the other two electrodes. The higher or lower insertion speed causes smaller tissue strain for the two optimized electrodes, which is conductive to set implantation parameters to minimize tissue injury.

This investigation evaluated the applicability of a molybdenum sulfide reference electrode (MSRE) as an internal reference electrode for use in alkaline sulfide solutions over a range of pulp digester liquors at 170°C. The electrode remained stable during the exposure period of two weeks. The experimentally determined half cell potential of the MSRE is E = -0.91 VSHE. The surface of the MSRE was examined by scanning electron microscope (SEM) and electron spectroscopy for chemical analysis (ESCA) to verify the chemical composition of the thin surface film. Based on ESCA studies, the surface film contained molybdenum disulfide and sodium disulfide. During storage of the specimens, sulfide was partly oxidized to sodium sulfite in air. Next to the metallic molybdenum, a mixed molybdenum disulfide and molybdenum hydroxide layer was detected.

<p>We describe the growth and characterization of highly fluorescing, near-infrared-emitting nanoclusters made of bimetallic Au<sub>25-x</sub>Ag<sub>x</sub> cores, prepared using various monothiol-appended hydrophobic and hydrophilic ligands. The reaction uses well-defined triphenylphosphine-protected Au<sub>11</sub> clusters (as precursors), which are reacted with Ag(I)-thiolate complexes. The prepared nanoclusters are small (diameter < 2nm, as characterized by TEM) with emission peak at 760 nm and long lifetime (~12 µs). The quantum yield measured for these materials was 0.3 - 0.4 depending on the ligand. XPS measurements show the presence of both metal atoms in the core, with measured binding energies that agree with reported values for nanocluster materials. The NIR emission combined with high quantum yield, small size and ease of surface functionalization afforded by the coating, make these materials suitable to implement investigations that address fundamental questions and potentially useful for biological sensing and imaging applications.<br></p>
