Quantum point contacts are in use as an on-chip capacitative readout for the charge state of quantum dot systems. Here we investigate experimentally the back-action of quantum point contacts (QPCs) on a nearby double quantum dot (DQD). Driving current through a QPC influences the DQD state and leads to a measurable current flow in the DQD circuit with no bias voltage applied. The responsible me...

We report the electrochemical performance of a redox polymer-mediated glucose anode catalyzed by glucose oxidase and supported on a multiscale carbon material. The support is composed of carbon paper upon which is grown multiwall nanotubes by chemical vapor deposition combined with ohmic heating of the carbon paper. The material possessed 100-fold higher surface area and demonstrated tenfold hi...

The intake of nitrite in sausages is a concern for health-conscious consumers. This study investigated the effects heating method (smokehouse, water bath, or ohmic heating), temperature (40, 60, 75°C), sodium level (80 250 ppm), and frozen storage period (≤3 days 4 weeks) on residual nitrite, pigments, curing efficiency chicken sausages. results indicated that electrical conductivities samples ...
