Influencing the "injection barriers" into prototype molecular wires through metal-molecule Context: Many NIST customers using our vacuum calibration services spanning the pressure range from 0.65 Pa to 133 kPa (5 millitorr to 1000 torr) desire direct traceability to NIST but cannot justify the cost of calibration against relative to the NIST NIST Ultrasonic Interferometer Manometers (UIMs).
