Temperature accuracy and temperature gradients in solution-state NMR spectrometers.
In solution-state NMR spectrometers, there is a systematic deviation between the temperature of the sample and the temperature reported by the spectrometer. In addition, temperature gradients are often present in the sample. The size of both the temperature deviations and the temperature gradients depends on several factors, including the temperature, the flow rate of the heating/cooling gas, a...
متن کاملMeasuring temperature gradients over nanometer length scales.
When a quantum dot is subjected to a thermal gradient, the temperature of electrons entering the dot can be determined from the dot's thermocurrent if the conductance spectrum and background temperature are known. We demonstrate this technique by measuring the temperature difference across a 15 nm quantum dot embedded in a nanowire. This technique can be used when the dot's energy states are se...
متن کاملTemperature gradients in the rabbit eye.
Measurements of the temperature of the various parts of the rabbit eye under both local and general Nembutal anesthesia were made ivith the thermistor as the temperature-measuring device at a room temperature of 22 to 24° C, and a relative humidity of 33 to 53 per cent. The equipment and its calibration are described in detail. The existence of a temperature difference of 6° C. (corrected for t...
متن کاملSpatial temperature gradients guide axonal outgrowth
Formation of neural networks during development and regeneration after injury depends on accuracy of axonal pathfinding, which is primarily believed to be influenced by chemical cues. Recently, there is growing evidence that physical cues can play crucial role in axonal guidance. However, detailed mechanism involved in such guidance cues is lacking. By using weakly-focused near-infrared continu...
