2015
Nitrogen is an effective supercritical fluid for extraction or drying processes due to its small molecular size, high density in the near-liquid supercritical regime, and chemical inertness. We present a supercritical nitrogen drying protocol for the purification treatment of reactive, porous materials.

Porous substrate electroporation (PSEP) pairs consistent, high throughput delivery with high cell viability. Introduction of transepithelial electrical impedance (TEEI) measurements provides insight into the intermediate processes of PSEP and allows for label-free delivery. This article discusses a method for performing PSEP delivery experiments and TEEI measurement analysis simultaneously.
FAQs
Performance is governed by the geometry of the void network. Pore size and shape affect how fluids, gases, heat, and molecules move, while connectivity determines whether pathways remain continuous or isolated. These features therefore influence permeability, selective transport, surface interactions, and density. Engineering designs adjust pore architecture when targeting filtration, insulation, separation, or lightweight structural performance.
Surface chemistry controls how molecules interact with the internal surfaces of the solid. This interaction is especially important for adsorption, separation, and catalysis, where performance depends on what the material can retain, transport, or support at its surfaces. Combining suitable chemistry with a controlled pore network allows engineers to tailor materials for specific chemical processing and treatment functions.
Interconnected pores can create continuous routes for fluid, gas, heat, or molecular transport, supporting permeability and separation. Isolated pores do not provide the same connected pathways, but their presence still contributes to characteristics such as reduced density and altered thermal behavior. Selecting between these architectures depends on whether an application prioritizes transport, insulation, or lightweight design.
Researchers can modify composition and pore architecture through foaming, sintering, or templating. These approaches provide routes for creating different internal structures rather than relying on a single fixed material design. The resulting changes can adjust density, surface area, permeability, and transport behavior, helping align the material with requirements in filtration, catalysis, adsorption, energy storage, or structural engineering.
Their combination of low density, high surface area, permeability, and selective transport supports several engineering roles. Porous materials can serve in filtration and water treatment, catalysis and chemical processing, adsorption and separation, energy storage, thermal insulation, and lightweight structural design. The relevant choice depends on which transport, surface, thermal, or mechanical-related property the application requires.
Selection should begin with the required transport and surface behavior. Filtration and separation depend strongly on pore architecture, permeability, and selective transport, while adsorption also relies on interactions at the material surface. Engineers therefore compare pore size, connectivity, and surface chemistry with the intended fluid, gas, or molecular process before choosing a composition and fabrication approach.
Porous materials extend beyond conventional filtration and chemical processing into biomedical devices and sustainable manufacturing. Their tunable composition and internal architecture allow engineers to adapt density, transport, surface area, and related performance characteristics to different design goals. This flexibility supports the development of application-specific materials while connecting porous-material engineering with resource-conscious production and device design.
