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.

A facile, one-pot synthesis of N-succinimidyl-4-[18F]fluorobenzoate ([18F]SFB) was developed based on a non-aqueous, three-step radiochemical process. Using microwave heating, the entire procedure can be completed in less than 30 min, or 60 min with further purification by preparative HPLC. The decay-corrected radiochemical yields (RCYs) were 35-5% (n > 30).
FAQs
The key effect occurs while the casting material cures: elevated air pressure compresses gas bubbles suspended in the liquid and limits their expansion. As the material solidifies, fewer enlarged voids remain within the cast. This produces a denser object with a smoother, less porous surface, which is especially useful when the replica or model must preserve clear shape and visible detail.
Bubble suppression matters because internal voids can become casting defects rather than merely cosmetic marks. By reducing these defects, the finished object becomes more reliable for uses that depend on consistent form and surface quality. In biological work, that can improve the visual clarity of anatomical models and make replicas or holders more dependable during teaching, experimental setup, or documentation.
Three elements define the casting setup: the mold establishes the intended shape, the liquid casting material becomes the solid object during curing, and the pressure pot supplies elevated air pressure that acts on bubbles in the material. Keeping these roles distinct helps explain why pressure treatment improves the cast while working together with the mold and, often, resin as the casting material.
A basic workflow starts by placing the liquid casting material, often resin, inside a mold. The mold and material are then subjected to elevated air pressure while curing takes place. After the material solidifies, the cast can be used as a replica, model, holder, or custom component. The central procedural objective is applying pressure during curing so suspended bubbles do not expand.
Pressure pot casting is useful when a biological object must be represented with a durable, accurately shaped cast. Supported uses include anatomical models, specimen holders, custom laboratory components, and replicas. These products can serve teaching, experimental setup, and research documentation, particularly when smooth surfaces and reduced porosity improve handling or visual inspection.
Expected outcomes include a denser cast, a smoother and less porous surface, and fewer casting defects. For biological applications, those qualities can improve the reliability and visual clarity of models, replicas, specimen holders, and custom laboratory components. The practical value therefore lies in producing physical objects whose shape and surface are better suited to teaching, experimental setup, and research documentation.
