A Simplified Recording Potentiometer.

(WITH SIX FIGURES) Some years ago (1) the author described a recording potentiometer designed primarily to meet the requirements of flexibility so necessary in physiological work. A number of these instruments were built and are still in use. Ever since this earlier instrument was developed the writer has continued to improve and simplify until now one which is far superior in all respects to t...

A single-molecule potentiometer.

Controlling electron transport through a single-molecule device is key to the realization of nanoscale electronic components. A design requirement for single molecule electrical devices is that the molecule must be both structurally and electrically connected to the metallic electrodes. Typically, the mechanical and electrical contacts are achieved by the same chemical moiety. In this study, we...

A thermocouple for the brain.

IT seems ludicrous that the reading of a rectal thermometer should be taken as a guide for deciding how long a major cerebral artery may be safely clamped by a neurosurgeon. Although the temperature of the brain must approximate that of the blood passing through it, temperature gradients are present throughout the body during hypothermia and the reading on the thermometer will vary with the dis...

Problems Encountered in Fluctuating Flame Temperature Measurements by Thermocouple

Some thermocouple experiments were carried out in order to obtain sensitivity of thermocouple readings to fluctuations in flames and to determine if the average thermocouple reading was representative of the local volume temperature for fluctuating flames. The thermocouples considered were an exposed junction thermocouple and a fully sheathed thermocouple with comparable time constants. Either ...

Thermocouple Measurement

In 1822, Thomas Seebeck, an Estonian physician, accidentally joined semicircular pieces of bismuth and copper (Figure 1) while studying thermal effects on galvanic arrangements. A nearby compass indicated a magnetic disturbance. Seebeck experimented repeatedly with different metal combinations at various temperatures, noting relative magnetic fi eld strengths. Curiously, he did not believe that...
