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.

Long and hollow glassy carbon microfibers were fabricated based on the pyrolysis of a natural product, human hair. The two fabrication steps of carbon microelectromechanical and carbon nanoelectromechanical systems, or C-MEMS and C-NEMS, are: (i) photolithography of a carbon-rich polymer precursor and (ii) pyrolysis of the patterned polymer precursor.

This video showcases the development and differentiation of human neural stem cells within a three-dimensional scaffold. A laminin coating on the scaffold promotes cell attachment, while a growth factor-free neural medium induces cell differentiation into neural progenitor cells, which extend their processes within a porous architecture in multiple directions, forming a three-dimensional...

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle. Biological Carbon Cycle All...

This article describes the effect of dissimilar charging/discharging temperatures on the degradation of lithium iron phosphate-graphite pouch cells, aiming at simulating close to real case scenarios. In total, 10 temperature combinations are investigated in the range -20 to 30 °C in order to analyze the impact of temperature on degradation.
FAQs
Retention reflects the combined effects of surface chemistry and pore architecture. Graphitized sp² carbon planes provide hydrophobic regions that can engage analytes through dispersion forces and π–π interactions, while nanoscale pores alter how molecules access and contact those surfaces. This coupling gives the stationary phase distinctive selectivity, helping separate compounds according to differences in their interactions with the material.
Solvent composition and pH can alter surface-induced retention, particularly for polar compounds. Changes in these conditions modify how strongly analytes interact with the graphitic surface and pore environment, shifting their chromatographic behavior. Controlling these variables is therefore important when optimizing a separation or interpreting why a compound elutes differently.
Porous graphitic carbon is useful when conventional materials do not adequately resolve target biomolecules. Its hydrophobic graphitic planes and nanoscale pore network create adsorption behavior based on dispersion forces, π–π interactions, and surface-induced retention. This gives chromatographic separations an alternative selectivity for challenging samples, including species that conventional approaches struggle to distinguish.
As a stationary phase, it provides the interaction surface through which a sample’s biomolecules are retained differently and then separated during liquid chromatography. The resulting separation can be used for structural characterization or purification, depending on the research goal. This role connects material properties directly to measurable chromatographic resolution.
Carbohydrates, glycans, and peptides are key biochemical targets, along with other biomolecules that conventional materials may not resolve effectively. Applying the stationary phase to these classes can support both separation and downstream interpretation, making it relevant to biochemical studies that require structural characterization rather than only broad sample handling.
The chromatographic separation can be incorporated into mass spectrometry workflows for biochemical samples. The same separations also support purification and structural characterization. Consequently, the material contributes not only to resolving analytes, but also to obtaining information about biomolecular structure through subsequent research steps.
