|May 1, 1979
Summary
A new hand pump generates high hydrostatic pressure for magnetic resonance studies. This design simplifies high-pressure experiments by reducing the space needed between magnet poles.
Area of Science:
- Physics
- Chemistry
- Materials Science
Background:
- High-pressure studies are crucial for understanding material properties.
- Magnetic resonance is a powerful technique for probing molecular and material structures.
- Existing high-pressure equipment can be bulky and difficult to integrate with magnetic resonance setups.
Purpose of the Study:
- To develop a novel reciprocating hand pump for generating high hydrostatic pressures up to 20 kilobars.
- To facilitate high-pressure magnetic resonance studies by creating a more compact experimental setup.
- To adapt existing high-pressure seal designs for improved performance and integration.
Main Methods:
- Construction of a reciprocating hand pump with a separate pump body and high-pressure cell.
- Utilization of modified unsupported area seal connectors based on Warschauer and Paul's design.
- Integration of the pump system with a magnetic resonance apparatus.
Main Results:
- Successfully constructed a hand pump capable of generating hydrostatic pressures up to 20 kilobars.
- The two-unit design (pump body and cell) connected by high-pressure tubing reduces the required workspace.
- The modified connectors ensure reliable sealing at high pressures.
Conclusions:
- The developed hand pump enables high-pressure magnetic resonance studies in a more accessible manner.
- The compact design overcomes limitations of previous high-pressure setups for magnetic resonance.
- This innovation opens possibilities for new research in materials science and chemistry under extreme conditions.

02:57Definition and Measurement of Pressure: Atmospheric Pressure, Barometer, and Manometer
Gas pressure is caused by force exerted by gas molecules colliding with the surfaces of objects. Although the force of each collision is very small, any surface of an appreciable area experiences a large number of collisions in a short time, which can result in high pressure.
01:20Pressure Gauges
Most pressure gauges, like those on scuba tanks, are calibrated to read zero at atmospheric pressure. Readings from such gauges are called the gauge pressure, which is the pressure relative to atmospheric pressure. When the pressure inside the tank exceeds atmospheric pressure, the gauge reports a positive value. Some gauges are designed to measure negative pressure. For example, many physics experiments must take place in a vacuum chamber, a rigid chamber from which some of the air is pumped...
01:18Variation of Atmospheric Pressure
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...

03:02Constant Pressure Calorimetry
Calorimetry is a technique used to measure the amount of heat involved in a chemical or physical process or to measure the heat transferred to or from a substance. The heat is exchanged with a calibrated and insulated device called the calorimeter. Calorimetry experiments are based on the assumption that there is no heat exchange between the insulated calorimeter and the external environment. The well-insulated calorimeters prevent the transfer of heat between the calorimeter and its external...
01:24Pressure Relationships in Thoracic Cavity
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs during...

01:14Pressure of Fluids
There are many examples of pressure in fluids in everyday life, such as in relation to blood (high or low blood pressure) and in relation to weather (high- and low-pressure weather systems). A given force can have a significantly different effect, depending on the area over which the force is exerted. For instance, a force applied to an area of 1 mm2 has a pressure that is 100 times greater than the same force applied to an area of 1 cm2. That's why a sharp needle is able to poke through skin...
