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.

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces. The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive force...
FAQs
The process uses interface-pressure sensors or force measurements to identify changes in contact load. A control response can then alter device position, applied force, inflation, or support conditions. Maintaining the selected pressure range helps create more consistent contact between tissue and a medical device or support surface, which can improve safety and support the intended mechanical function.
A measured contact load does not describe the entire clinical situation by itself. Pressure Contact Control connects mechanical measurements with tissue response and device performance, allowing clinicians and researchers to consider whether a device is interacting safely and functioning as intended. This combined perspective supports more individualized decisions about positioning, fitting, support, and treatment conditions.
Contact pressure may change when the position of a patient, device, or body tissue changes, or when applied force, inflation, or support conditions are adjusted. Because these variables alter the mechanical interaction at the contact site, monitoring can reveal whether pressure has moved outside the desired range. The information can then guide a corresponding control adjustment.
A typical workflow begins by placing interface-pressure sensing or force-measurement equipment at the relevant contact area. The measured load is compared with a target range, after which position, applied force, inflation, or support conditions may be adjusted. Repeated measurement and adjustment help establish consistent treatment conditions and provide data for evaluating device or tissue interaction.
Applications include pressure-injury prevention, patient positioning, prosthetic and orthotic fitting, rehabilitation, and instrumented diagnostics. In each setting, contact measurements help characterize how a device, support surface, or tissue interface behaves under use. The resulting information can guide safer positioning, improve fitting decisions, or support evaluation of mechanical conditions relevant to treatment and function.
Measurements show how mechanical load is distributed or transmitted at a specific contact interface, while related observations connect that load with tissue response and device performance. This evidence can inform individualized prosthetic or orthotic fitting and broader device design decisions. It also gives clinical teams a basis for comparing contact conditions and selecting more appropriate support or positioning strategies.
