Monolayer of PDDA/graphene/PDDA/H(2)PtCl(6) is fabricated on conductive glass using electrostatic layer-by-layer self-assembly technique, which is then converted to graphene/Pt monolayer for use as counter electrode in dye-sensitized solar cell (DSSC). As compared to the sputtered Pt counter electrode, the self-assembled monolayer reduces the Pt amount by about 1000-fold but exhibits comparable...
Rhodes, Apsimon, and Lawrie (1966) have recently measured pH in the duodenal bulb for long periodsl* using two glass electrodes. By this method it is possible to maintain the distal electrode within the duodenal bulb for long periods but its exact position in the bulb cannot be determined. Over short _.... periods of time, however, the electrode can be located accurately by radiological methods...
The simplest transducer in the development of potentiometric biosensors is the glass pH electrode. Glucose oxidase immobilization was achieved using cellophane [1], nylon [1-6] or nitrocellulose [5,7] membranes that are subsequently fixed on the sensitive bulb of the pH electrode that senses the pH diminution, as a result of the biocatalytical reaction occurring in the enzyme layer (glucose oxi...
Cadmium(II) is a common water pollutant with high toxicity. It is of significant importance for detecting aqueous contaminants accurately, as these contaminants are harmful to human health and environment. This paper describes the fabrication, characterization, and application of an environment-friendly graphene (Gr)/L-cysteine/gold electrode to detect trace levels of cadmium (Cd) by differenti...
We propose a new simple, low-cost method for providing all-round metal contacts to one-dimensional structures such as carbon nanotubes and nanowires on a transparent substrate. The nanostructures are first positioned in place to bridge a electrode gap by dielectrophoresis. The electrode structure is then used as a self-aligned mask during the subsequent photolithography through illumination fro...
Here we report a new type of sensing platform that is based on electrodissolution of a metallic bipolar electrode (BPE). When the target DNA binds to the capture probe at the cathodic pole of the BPE, it triggers the oxidation and dissolution of Ag metal present at the anodic pole. The loss of Ag is easily detectable with the naked eye or a magnifying glass and provides a permanent record of th...
Index-matched indium tin oxide (ITO) electrodes for capacitive touch screen panels have been fabricated to improve optical transmittance and reduce the difference of reflectance (deltaR) between the etched and un-etched regions. 8.5 nm Nb2O5 and 49 nm SiO2 thin films were deposited by magnetron sputtering as index-matching layers between an ITO electrode and a glass substrate. In case of 30 nm ...

Chemical exfoliated ultra-thin MoS2 nanosheets (NSs) with well 2D structure were demonstrated for interfacial layers and Ag nanowires composite transparent electrode in polymer solar cells (PSCs). The smooth and uniform n-type and p-type (after the plasma treatment) MoS2 NSs could improve fill factor of devices and light absorption in active layer. The optimized Ag nanowires-MoS2 NSs (AgNW-MoS2...
Present address: Xiao-Liang Wang, Seeo, Inc., 3906 Trust Way, Hayward, CA 94545, USA The review presents an overview of the recent advances in inorganic solid lithium ion conductors, which are of great interest as solid electrolytes in all-solid-state lithium batteries. It is focused on two major categories: crystalline electrolytes and glass-based electrolytes. Important systems such as thio-L...
