The laser heated diamond anvil cell combined with synchrotron micro-diffraction techniques allows researchers to explore the nature and properties of new phases of matter at extreme pressure and temperature (PT) conditions. Heterogeneous samples can be characterized in situ under high pressure by 2D mapping and combined powder, single-crystal and multigrain diffraction approaches.

Drosophila is famous for its powerful genetic manipulation, but not for its suitability of in-depth biochemical analysis. Here we present a TAP-based procedure to identify interacting partners of any protein of interest from the fly brain. This procedure can potentially lead to new avenues of research.

Vapor Pressure

When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules move randomly about, they will occasionally collide with the surface of the condensed phase, and in some cases, these collisions will result in the molecules re-entering the condensed phase. The change from the gas phase to the liquid is called condensation. When the rate of condensation becomes equal to the rate of vaporization, neither the amount of the liquid nor the amount of the vapor...
FAQs
Flush placement helps the opening sense pressure at the wall rather than allowing the measurement to be strongly influenced by the fluid’s motion. This matters because pressure taps are intended to report local static pressure, not a value dominated by velocity effects. In pipe, duct, vessel, or aerodynamic-surface measurements, careful placement therefore improves the usefulness of the pressure reading.
Orientation works together with placement to reduce measurement disturbance. A suitably oriented tap can better represent the wall pressure while limiting the influence of turbulence at the opening. Engineers must also avoid leakage, since a leak can alter the connection between the flow system and the gauge, manometer, or transducer. These design details directly affect measurement accuracy.
Comparing readings from pressure taps at different locations reveals how pressure changes through a system. Engineers can use those changes to determine pressure loss and assess the behavior of components such as pumps and valves. The result links a local wall-pressure measurement to system performance, helping identify whether observed pressure behavior agrees with the expected operation.
Pressure-tap measurements provide an experimental check on Bernoulli-based predictions. Engineers compare measured local static pressures with the pressures predicted for the flow arrangement, then use agreement or disagreement to assess the analysis. This makes taps useful for validating flow calculations while also characterizing the behavior of real systems rather than relying only on theoretical expectations.
A practical measurement setup begins by selecting a flush location representative of the region of interest and connecting the tap to a pressure gauge, manometer, or transducer. Measurements can then be taken at one or more locations and compared to evaluate pressure changes. The chosen instrument depends on the monitoring arrangement, while tap placement remains central to reliable results.
Applications span several engineering environments because the same measurement principle can be adapted to different flow systems. Pressure taps help monitor HVAC airflow, investigate conditions in wind tunnels, and characterize fluid machinery. They also support pump and valve evaluation in piping systems. Across these settings, the measured pressure information aids analysis, verification, and efficient, safe operation.
