Robert M Rioux, Pennsylvania State University, University Park, PA The use of gases in a synthetic chemistry laboratory is essential for carrying out a variety of highly facile and atom economical transformations. Reactions such as hydrogenation, oxidation, and amination require the use of gases like hydrogen, oxygen, and ammonia. Due to the poor solubility of these gases in typical reactant solutions, high pressures are necessary to achieve a meaningful reaction rate. Not only are these gases...

We describe a "gold standard" for evaluating orthostatic tolerance (OT) using tilt testing with combined lower body negative pressure (LBNP). This can be combined with non-invasive evaluations of cardiovascular reflex control. Normal and abnormal responses are defined.

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.

Source: Alexander S Rattner and Kevin Rao Li Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA The objective of this experiment is to demonstrate the phenomenon of stability of floating vessels - the ability to self-right when rolled over to the side by some external force. Careful design of hull shapes and internal mass distribution enables seagoing vessels to be stable with low drafts (submerged depth of hull), improving vessel...

Here we present a protocol for performing reactions in simple reaction vessels under low-to-moderate pressures of CO2. The reactions can be performed in a variety of vessels simply by administering the carbon dioxide in the form of dry ice, without the need for costly or elaborate equipment or set-ups.
FAQs
Hydrostatic testing applies pressure through an incompressible liquid, allowing inspectors to evaluate whether an enclosed vessel maintains structural integrity under defined conditions. The assessment focuses on observable outcomes such as leaks, permanent deformation, and pressure loss. In chemistry settings, this approach supports safer evaluation of reaction vessels, autoclaves, gas cylinders, and storage systems.
Pneumatic testing uses a gas rather than an incompressible liquid to apply pressure. This provides a different test condition for evaluating enclosed containers, while inspectors still monitor for leakage, permanent deformation, and pressure loss. The distinction matters when laboratories or manufacturing facilities assess equipment used with gases, liquids, or controlled chemical reactions.
Three important warning signs are leakage, permanent deformation, and pressure loss under the defined test conditions. Leakage indicates that containment is not maintained, while permanent deformation suggests that the vessel has changed shape under pressure. Pressure loss can also signal compromised integrity, making these observations important for decisions about safe operation in chemical environments.
In chemical equipment, pressure does not operate in isolation. Temperature and corrosive chemicals can interact with pressurized conditions while a reaction or storage process is underway. Pressure vessel testing therefore contributes to confidence that equipment can maintain controlled reaction conditions and contain materials safely when these factors are present together in laboratories or manufacturing facilities.
Inspectors monitor the vessel under defined test conditions, paying particular attention to leaks, permanent deformation, and pressure loss. The selected pressure method may use an incompressible liquid or a gas, depending on the assessment. These observations provide evidence about structural integrity and safe operation rather than relying only on the vessel’s intended use or appearance.
The evaluation supports the safe use of reaction vessels, autoclaves, gas cylinders, and storage systems. In laboratories, it helps protect personnel and preserve controlled reaction conditions. In manufacturing facilities, the same principles help prevent releases and equipment failure when enclosed systems handle pressurized gases or liquids and may also encounter temperature changes or corrosive chemicals.
